How To Install A Power Vent Gas Water Heater?

How to Install a Power-Vented Water Heater: Replace an Electrical Outlet

1. You may make it easier to operate the vent by installing some type of combustible gas (or propane) water radiator that is ″control vented.″ This type of venting framework is not the same as the type of venting framework used on the majority of gas water radiators.
2. The majority of them feature a ″natural-draft″ style of vent, in which the hot waste gases rise via an open draft diverter and into metal pipes that finally flow outside.
3. Maintaining one of these vents is time-consuming and may be expensive.
4. It’s best if you leave it to the professionals.

Power vents streamline a gas heated water storage establishment

1. The biggest advantage of using a power vent is that the water heater can be installed virtually anywhere.
2. Most crucially, it does not necessitate the installation of a vertical vent or chimney.
3. There are several possibilities here.
4. It is possible that the site where you wish to install your hot water heater is not close to the chimney, or that your home does not have a chimney.
5. Whatever method is used, a power vent may be ventilated by simply extending cheap pipe horizontally across the room.
6. However, there is a disadvantage to using this sort of water heater in terms of total cost consideration.

The blower/fan element of the vent requires electricity to function, which increases the cost of the blower or fan itself as well as the expense of providing a power line to the fan itself.Overall, because a fan/blower is required to run the power vent, the expenses of heating water will be greater over the power vent’s service life.Using a petroleum gas or propane warmer instead of an electric water radiator can help you save money on your electricity expenses.At that time, consider introducing a power-vented model with a sidewall that is successfully vented out to reduce establishment expenses.While power-vented water warmers perform similarly to typical water radiators, the fumes and gases are buried by a small fan rather than rising upwards via metal channels.You Might Find the Following Information Useful: What is causing my hot water tank overflow line to drip?

Tips

1. Despite the fact that power-vented water warmers are more expensive than conventional draft radiators, the establishment will be less on the off chance that you do not have a present smokestack.
2. You should be familiar with pipes, gas channeling, and electrical wiring, and you may be required to have the project reviewed.
3. Tools that will be required for this project Preparing the necessary tools and equipment for this do-it-yourself project ahead of time will save you time and frustration later on.

Converting atmospheric vent to direct or Power Vent

1. Control vent water radiators, direct vent water radiators, and power direct vent water radiators are the three types of water radiators to consider.
2. Every kind has its own set of advantages and disadvantages.
3. The power vent water radiators employ an electric fan to exhaust the fumes produced by the burning out of the water, and these types pull the air from within the building.
4. Due to the negative pressure that might impact the functioning of these heaters, they cannot be connected to a chimney or shared with any other equipment.
5. It is the recommended kind in the event that you need to run a lengthy pipe and want adjustability in the installation process.
6. Direct venting is recommended for homes if you do not want to be dependant on electricity since these devices evacuate the pipe gases by using the difference in weight between the hot pipe air and the cooler outside air.

Furthermore, you won’t have to be concerned about a possible spill because these units use outside air for ignition and have a permanent burning chamber and pipes in place.In addition, because there are no moving components, these models create no disturbance, require substantially less maintenance, and as a result, there are less things that might go wrong and cause you concern.

About the DV Heaters

1. The usage of DV heaters significantly reduces the likelihood of the home experiencing negative pressure.
2. It is possible to have a single point of termination for the vent with the pipe within the pipe type.
3. The drawback is the restriction on travel distances.
4. Power When the indoor air quality is an issue, direct venting is employed.
5. It pulls in fresh air from the outside for combustion while exhaust gases are removed from the combustion chamber by means of a fan.
6. Regarding your worry regarding the proximity of the water heater to the windows and other openings, there are laws that govern where a water heater vent may be placed, which includes how far away it must be from a door, window, deck, furnace exhaust, and other openings, among other things.

Your plumber should adhere to all applicable building and gas rules in the area, as well as any other applicable regulations.You can also refer to the handbook that came with your particular equipment.It’s important to remember that incorrect venting might result in carbon monoxide poisoning (it is odourless).

Can I replace a power vent water heater with a direct vent?

1. You will most likely be able to use a direct vent, but the exhaust system will need to be totally replaced.
2. Depending on the location of decks, windows, or doors, it may or may not be necessary to relocate the termination outdoors.
3. There should be no issues at all.
4. All that should be required of you is some little work on the cement blocks.
5. Because it is a pipe within a pipe, the pipe is significantly bigger.
6. It pulls in fresh air from the outside through the gap around the exhaust venting system.

Power vent water heater vs Direct vent

When using an instantaneous vent water warmer, the water is warmed by the heat generated by the ignition of the fuel. In light of this, it is common for an instantaneous vent framework to result in reduced water heating expenditures than before. Similarly to the power vent water radiator, the fumes gases are vented vertically, requiring no extra electrical power.

1. A power vent water heater exhausts gases by forcing them through vent pipes that are horizontally oriented, which is accomplished by the use of a blower or fan.
2. In certain cases, this may be the only form of water heater that makes sense because it does not require the use of a chimney or vertical vent to function properly.
3. Some places do not have access to a chimney or vertical vent, which means your options are restricted in these situations.

The differences between a power vent and a direct vent hot water heater are apparent, and it goes without saying that a power vent will result in a greater cost – but there are instances when this is just not an option. In situations when you do not have access to a vertical vent or chimney, a power vent may be the best option for you to choose from.

Direct vent water heater

When utilizing a direct vent water heater, the water is heated by the heat generated by the combustion of the fuel. In most cases, using a direct vent system will result in cheaper water heating expenses. In addition, because the exhaust gases are vented vertically, there is no need for additional power, as there is with a power vent water heater.

Rheem power vent water heater

1. The Rheem Power Vent is a high-efficiency gas water heater with a productivity of.67 EF and a long life expectancy.
2. The Power Vent is available in tall and short capacities of 40 and 50 gallons.
3. Versions with a First Hour Rating (FHR) of up to 71 gallons are available, while models with a First Hour Rating (FHR) of up to 87 gallons are available.
4. The Power Vent is equipped with a coordinated self-indicating architecture that makes installation and maintenance a breeze.

1. Metal channel valves as well as a T&P valve are included, and an approved magnesium anode pole protects the tank from rusting and consumption while it is in use.
2. The Guardian System is equipped with an air/fuel shut-off device that shuts off the warmer if a buildup of flammable vapor occurs.
3. The Power Vent provides venting runs of up to 100 feet in length, with pipe options including PVC, ABS, and CPVC.

• Most of the time, the warranty for the Rheem Power Vent water heater included the following provisions: 6-year limited tank warranty
• 6-year limited parts warranty
• 6-year limited labor warranty

The limited warranty does not cover the cost of labor in any way.

Can a standard water heater be side-vented?

1. A specific number of feet is raised in order to pull the gasses up and out before they are skewed to a particular degree.
2. You can purchase a Tjernlund side wall vent kit, however it will likely cost as much as a power vent water heater due to the higher cost of the kit.
3. If your water heater is located close to an exterior wall, you may want to consider a direct vent water heater.
4. Despite the fact that they are a little more expensive, they do not require electricity to operate.

Water heater vent types

1. A venting system is required for every water heater that uses natural gas or propane as a fuel.
2. The process of burning the gas is referred to as combustion, and it results in the production of heat, exhaust gases (including very toxic carbon monoxide), and moisture.
3. It is the ventilation system of the water heater that eliminates these by-products from the residence, which makes it an essential safety element.
4. In the majority of situations, the kind of ventilation system used is dictated by the type of water heater chosen.

Water Heater Venting Basics

1. In order to expel exhaust gases from the water heater to the outside, all water warmer venting systems make use of a vent pipe or pipe, which is also known as a fireplace pipe or a pipe.
2. Depending on the type of vent framework used, the channel may be made of metal or plastic material.
3. It is possible for water radiator conduits to be connected to a single outside vent pipe, or they may be integrated with a larger vent pipe that also feeds a gas or propane heater or evaporator in the house.
4. Most of the time, the gases from the larger apparatus warm up the ordinary vent, which helps the water warmer vent move more quickly.
5. Gas and propane water radiators, regardless of whether they are vented, require an air supply for igniting.
6. This might come from the surrounding air in the home, or it can come in through a vent pipe that draws air in from the outside, depending on the source.

Proper Venting Prevents Back drafting

1. Back drafting is the most well-known problem associated with water warmer venting, and it is caused by a situation known as back drafting.
2. The exhaust from the water radiator fails to exit the residence through the vent and instead condenses within the home.
3. Even though there are several reasons of backdrafting, the most common are faulty vent structure or installation, as well as a potential imbalance in the amount of air flowing through the residence.
4. As a result of ventilation fans, such as bathroom or kitchen vent fans, which pull in some circulation into the house while creating a suction effect that draws exhaust down and into the house from the water radiator vent, the last is frequently a result of the former.
5. Some water warmer venting frameworks, for example, those that utilize fan-assisted ventilation or direct venting innovation, eliminate the possibility of backdrafting.

Atmospheric Venting

1. Air venting is used by standard water warmers, which are the most generally recognized type.
2. The vent is comprised of a vertical or upward-inclining vent channel that is generally integrated with a standard vent channel.
3. In accordance with the premise that sight-seeing increases, the framework is entirely dependent on common convection to function.
4. Normally, hot gases from the water warmer rise through the vent and into the surrounding air, creating a pull that propels the upward wind stream farther up the chimney.
5. As the temperature of the vent pipe rises, the strength of the pull increases.
6. Climatic vent structures perform magnificently (and without the need for electricity) throughout the event.

In addition, the home is properly constructed and does not suffer from destructive surges.An inadequately constructed vent will frequently have a poor draw and will be vulnerable to back drafting to a great extent.

Power Venting

1. Water warmers with power venting are used in conjunction with an electric blower fan (which is usually quiet) that is installed above the water radiator and have either vertical or flat vent channels.
2. It is possible to run on a level plane to the exterior of the home, depending on how light the sight-seeing is to be.
3. The blower cools the air so that the vent may be maintained flowing in PVC pipe (as opposed to metal tubing, which is necessary with climatic venting) and is not difficult to collect when it is needed.
4. The water warmer must be located near an electrical outlet that can be used to regulate the fan.

Direct-Vent Water Heater

1. The air for ignition is obtained from a vent pipe that passes through an outside divider or the ceiling of the structure using an instantaneous vent framework.
2. It is possible that the fumes and gases are vented outdoors through a separate vent conduit or through an assembly of a similar pipe (this requires a twofold divider vent channel).
3. Direct-vent frames essentially ″inhale″ outside air, thus they are not subjected to the negative effects of back drafting in the home environment.
4. They also reduce the risk of unintentional fires caused by flammable fumes in the vicinity of a water heater.

Water Heaters for Mobile Homes

1. Water warmers in trailers are similar to those found in regular houses, but they should be specifically designed for this purpose.
2. When a water warmer is installed in a prefabricated house and is not clearly intended for that purpose, manufacturers frequently will not provide a warranty for it.
3. An exterior access board is usually required for standard climatic water warmers in prefabricated houses.
4. A fixed ignition unit with direct venting is almost certainly what you’ll find in a water warmer that’s been installed inside a prefabricated home without access to the outside world.

Power vents simplify a gas hot water heater installation

Mr. Fix-It-Up-For-The-Family Reduce excessive energy bills by replacing an electric water heater with a natural gas or propane heater. Then, to save money on installation expenses, choose a power-vented type that can be readily vented out a sidewall or a roof vent.

Installing a power vented water heater

Power-vented water heater

Power-vented water heaters operate in the same way as conventional water heaters, with the exception that the exhaust fumes are pushed out with a tiny fan rather than rising upwards through metal pipes.

Natural-draft water heater

A metal duct directs the hot exhaust gases from a natural-draft water heater to the outside.An open draft diverter directs the gases to the outside.The operation of natural gas or propane hot water heaters is normally less expensive than that of electric water heaters, but constructing a conventional vent in a house that does not have an existing chimney is more expensive.You’ll have an easier time running the vent if you choose to install a ″power-vented″ natural gas (or propane) water heater.This sort of venting system differs from the type of venting system seen on the majority of gas water heaters.The majority of them feature a ″natural-draft″ style of vent, in which the hot waste gases rise via an open draft diverter and into metal pipes that finally flow outside.

• Maintaining one of these vents is time-consuming and may be expensive.
• It’s best if you leave it to the professionals.
• A power-vented kind, on the other hand, is dependent on a fan to expel the exhaust gases.

Due to the fact that this approach does not rely on the inherent buoyancy of hot air, the vent pipes do not need to be installed higher up.They may be installed horizontally, which makes them considerably easier to install than vertically.Furthermore, because the fan dilutes the exhaust with colder air, you may run the vents using PVC tubing that is simple to build.Power venting is a particularly suitable option for more energy-efficient, closely constructed homes, where it is difficult to create a decent natural airflow due to the tight construction.

However, you should be aware of the following disadvantages:

1. The fan may be making a noise that you can hear. As a general rule, the water heater should be located in a room separate from the main living space in order to avoid being a nuisance.
2. You must have a normal electrical socket near the unit to supply power for the fan
3. you must ensure that you have an appropriate supply of ″make-up″ air to replace the air that is being blown out
4. and you must ensure that the machine is properly ventilated.
5. The third point to mention is that power-vented water heaters are at least 50% more expensive than natural-draft water heaters. Power-vented water heaters are available practically anywhere water heaters are marketed
6. they are manufactured by almost every major water heater manufacturer.

If you opt to install one yourself, make sure to thoroughly read the installation instructions and to adhere to all ventilation requirements. Additionally, contact your local building department to see whether you require a plumbing permit to do the repair.

Tips

• Power-vented water heaters are more expensive than natural-draft water heaters, but they are less expensive to install if you don’t already have a chimney.
• You should be knowledgeable with plumbing, gas piping, and electrical wiring, and you may be required to have the project examined.

Preparing all of your stuff ahead of time can save you time and money on last-minute buying visits. Here’s a list of things to do.

Can you add a power vent to a water heater?

No, no, and no!It is not necessary to use a power vent assembly unless the water heater was originally constructed with one and you are replacing it.Power vent water heaters are built in a different way than traditional water heaters.Water heater warranty and any homeowner’s insurance claims relating to the water heater will be voided as a result of this unsafe practice.The operation of natural gas or propane hot water heaters is normally less expensive than that of electric water heaters, but constructing a conventional vent in a house that does not have an existing chimney is more expensive.You’ll have an easier time running the vent if you choose to install a ″power-vented″ natural gas (or propane) water heater.

• Second, is it worthwhile to invest in a power vent water heater?
• Using a powervent water heater also has the added benefit of lowering your energy usage.
• Because they are more efficient, they consume less gasoline…

but not much less.Because they do not rely on a vent that goes up the middle of the house, powervent water heaters provide a great deal of freedom when it comes to where they may be installed in the home.How much does it cost to install a power vent water heater in this instance?Water heaters with a power vent.

In comparison to passive or direct vent systems, power venting a water heater costs around $500 to $1,000 extra per water heater.Power venting increases the cost of the device by $300-$600.Additionally, you’ll need to budget an extra $300-$500 for wiring and electrical work.What is the purpose of a power vent on a water heater?

1. To aid in the evacuation of exhaust gases from the hot water heater, power vent water heaters employ a fan or blower to circulate air through the unit.
2. It is possible that a power vent water heater will be your only option if your water heater is situated in an area that does not have access to a vertical vent or a fireplace.

How To Vent a Gas Water Heater

Similarly to a furnace, water heaters with gas burners will emit toxic gases including carbon monoxide, which is a result of the fuel used to light the burner in order to heat the water in the tank, regardless of whether the fuel is natural gas, liquid petroleum gas, or propane.In the same way that you need good venting for your furnace, you need adequate venting for your water heater in order to exhaust the harmful gases to the outside of your home in order to keep you and your family safe.

What you need to know about venting a gas water heater

Typically, the fumes from a typical gas water heater are expelled by a back draft insert and a flue.In order to prevent air from entering the top of the water heater and increase heat distribution in the tank, a back draft insert is installed.The flue is the venting system that allows fumes to escape safely from the house and be expelled into the outside air.An electric water heater that is equipped with atmospheric venting or direct venting will allow the fumes to exhaust naturally by rising straight up through a vertical vent that is routed to the home’s chimney or through an upward sloping vent that may be routed through the chimney or through a wall and out to the home’s outside.Both instances necessitate the placement of the water heater near an outside wall or a chimney in order for the ventilation system to function effectively.On some gas water heater types, a power vent blower fan will be employed to suck the exhaust gases out of the chimney and into the atmosphere.

• In comparison to a typical direct vent system, power venting water heaters are regarded to be more energy efficient and to be more successful in preventing back draft air from entering the water heater.
• Because the power vent makes use of a fan motor to drive the exhaust gases down the flue, the venting may be made longer and more horizontal, allowing you to choose from a wider variety of installation locations for your water heater.

Venting requirements

• While you should always check your local building rules to ensure that you are installing water heater venting in the appropriate manner, the following are some general suggestions to follow: The use of Type B metal flue piping with a diameter of three or four inches will be required if your water heater is designed to be vented into the atmosphere or directly into the atmosphere.
• A power vent system for water heaters can be vented using Schedule 40 PVC plastic tubing with a minimum diameter of two inches since the blower helps cool the air flowing through, however other experts say metal pipe is the safest option.
• Between the draft hood outlet and the first elbow or connector, there should be a minimum of 12 inches of vertical venting.
• Whenever possible, semi-horizontal pipe should have an upward slope of at least one quarter-inch per foot when used for direct venting. In order for the venting to function properly, the semi-horizontal distance should not exceed 75% of the total vertical height of the venting.
• In order to prevent air leaks, the venting pipe must be properly sealed where it runs through a wall or into the chimney.
• An UL-listed chimney or vent cap must be utilized to seal off the opening when venting through a chimney or other opening.

Additional gas water heater venting information and safety tips

• It is important to note that a direct venting system will draw combustion air from outside the residence (via the exhaust venting), whereas a power vent system would draw combustion air from the room air that surrounds the water heater. As a result, water heaters equipped with a power vent should not be put in tiny, enclosed locations.
• If space constraints necessitate the installation of the water heater in a utility closet, ensure that the closet doors are louvered or that enough room is provided at the top and bottom of the doors to allow for increased air movement.
• A power vent system may necessitate the installation of a slanted exhaust vent in order to adequately drain moisture that has accumulated in the pipe.
• Because gas water heaters operate on an open flame, keep flammable things such as paint cans away from the device.
• Because there is always the possibility that exhaust gases from a gas water heater or furnace can escape into your home, one or more carbon monoxide detectors should be put in your home near the bedrooms. It is necessary to check the detector batteries on a regular basis.

Replacing Your Water Heater? Don’t Overlook This One Key Factor

• Major Systems

If you’re in the market for a new water heater, installation will be easier if you stick to a water heater that vents the same way as your old one. But there are considerations beyond ease of installation. Read on to learn more.

Image courtesy of istockphoto.com When a home’s plumbing system is in good working order, homeowners seldom give the water heater a second consideration.A very different narrative unfolds when this critical appliance fails, interfering with all of the basic daily tasks that depend on having a constant supply of hot water available.When that happens, and you’re forced to take cold showers or wash your dinner dishes by hand, it’s likely that you’ll find yourself thinking about your water heater fairly often.If your water heater appears to be nearing the end of its useful life, or if it has completely ceased operating, you may be tempted to replace it as soon as possible.Rushing this choice, on the other hand, would be a mistake.For starters, there are many various types of water heaters available, each of which has a particular energy-efficiency profile to choose from.

• The type of water heater you pick will have a significant impact on how much you’ll end up paying to heat water on a consistent basis in the future.
• One other, more subtle reason to take your time is that ″choosing a replacement water heater carefully typically means avoiding extra installation charges,″ according to Daniel O’Brian, a technical consultant with SupplyHouse, a website that specializes in water heaters.
• If your present water heater requires venting, as the vast majority do, it is typically more cost-effective to purchase a replacement one that vents in the same manner.

If you don’t, you’ll almost certainly wind up spending more for installation than is actually necessary.Consult with a professional Identify qualified plumbing professionals in your area and receive free, no-obligation estimates for your plumbing project.+ That is not to imply that there is never a good reason to move to a water heater with a different venting system than the one you are currently using.In the words of O’Brian, ″A replacement that saves you a significant amount on your energy expenses may be well worth the additional installation cost.″ When evaluating your water heater alternatives, it’s important to address the issue of ventilation.

However, when it comes time to make a purchase, O’Brian advises that you ″consider both the upfront and recurring expenditures.″ Image courtesy of supplyhouse.com

Is Ventilation Necessary for Water Heaters?

Is it necessary to ventilate every water heater?No, but despite the fact that water heater technology has advanced significantly in recent years, combustion water heaters continue to be the most frequent.That is, the ordinary water heater continues to burn fuel, whether it is natural gas, oil, or propane, and the combustion of that fuel produces byproducts such as carbon monoxide.In the absence of adequate ventilation for the poisonous fumes produced by burning, contemporary water heating would be a potentially hazardous prospect.

Types of Water Heater Ventilation

• Unless you’re searching for a solar- or electric-powered water heater, or unless you live in a warm region and intend to install your water heater outside, you won’t have to worry about ventilation. Outside ventilation is required for virtually all other installations, but not every ventilation system operates in the same manner, and as a result, installation requirements might differ significantly. Figure 1 shows an example of an outside ventilation system. In the case of a water heater, atmospheric venting is a method in which the exhaust from the appliance naturally rises out of the appliance’s combustion chamber and travels up via a typical, chimney-style flue that culminates on top of the building. In contrast to certain other forms of ventilation, the atmospheric version does not need the installation of a motorized fan, but it does necessitate the installation of an exhaust pipe that extends uninterrupted from the water heater to the roof
• Due to the fact that they do not require a direct route to the roof, direct venting and power venting systems provide additional flexibility. A pipe that extends outside via an outside wall is often used to vent both systems. It is important to note that a power vent water heater draws combustion air from the surrounding environment before using a fan to force the exhaust through the vent. It is possible to use a direct vent system that draws fresh air from the outside and vents it through a horizontal pipe. Because of this difference in functioning, a direct vent water heater may be installed virtually anywhere, but a power vented water heater must be installed in a room with sufficient airflow to function properly.

O’Brian of Supply House explains that the decision between powered and non-powered venting frequently comes down to how the house is planned out and whether or not there is enough space for the venting to be installed. Image courtesy of supplyhouse.com

Power Vent Water Heater: Why You Should Buy One

When it comes to getting a new water heater, today’s homeowners have a plethora of alternatives to choose from.It seems like there is a water heater for every purpose, ranging from tankless versions with energy-efficient designs to tank-style units with smart technology embedded into them.One thing you may not have considered yet in your hunt for the ideal water heater is whether a direct vent or a power vent unit is the most appropriate for your needs.If you aren’t already thinking about this distinction, you should start right away.Continue reading to find out why.

What is a Power Vent Water Heater?

In order to remove potentially dangerous combustion emissions from your home, gas water heaters require venting.Direct vent and power vent are the two most prevalent venting systems on the market.The exhaust fumes from a power vent water heater are forced through vent pipes by an electric blower fan, which is powered by electricity.Additionally, the sort of venting required for these heaters is different from conventional heaters.Instead of using expensive metal venting, power venting heaters are fitted using less expensive PVC pipe.

Advantages 

There are several benefits to having a power vent water heater, but the freedom to put your heater virtually anywhere is undoubtedly the most significant.In addition, because these types of water heaters do not require vertical venting, a power vent water heater may exhaust gases through a horizontal vent to ensure proper ventilation.In other cases, a horizontal vent may be the only alternative available to you.In addition, many homeowners use these heaters to simply increase the removal of exhaust and to benefit from the peace of mind that comes with the extra layer of safety that these heaters provide.With the elimination of the possibility of backdraft, power vent water heaters significantly minimize the danger of carbon monoxide poisoning, however it is not completely eliminated in this situation.Another advantage is the reduction in energy use.

• Power vent water heaters are more energy efficient than traditional water heaters, which means they use less gas to run.
• The decreased energy use will save you some money, but it is unlikely to be more than $20 per year, making it an extra advantage rather than a decisive element in your decision.
• An issue that is sometimes neglected is the fact that many contemporary homes are constructed with energy efficiency in mind.

Because they are ″tightly constructed,″ it might be difficult to create a satisfactory natural airflow for ventilation in these structures.In this circumstance, a power vent water heater may be a smart alternative to consider.

Disadvantages

A power vent water heater, like any other appliance, has its downsides, which are listed below.To begin with, they are quite loud.However, you will hear the fan running, which is not the same sound as a mac truck.While this isn’t usually a problem if your heater is located in a basement or other inconspicuous spot, if it’s installed near a living space, you’ll most likely be aware while it’s running.Another drawback is that the fan will need to be hooked into an electrical outlet to function properly.If you have an electrical outlet nearby, that is not an issue; however, if you do not, you will need to have one built.

• One feature that many homeowners like about gas water heaters is that they can continue to run even if there is a power outage in the neighborhood.
• Water heaters that use a power vent do not fall under this category.
• If your electrical power is disrupted, your water heater will cease to function since it will be unable to expel the gases it produces.

Furthermore, power vent heaters are more expensive, ranging from 50 to 75 percent more expensive than direct vent heaters, and they have a shorter guarantee as well.In most circumstances, a guarantee of six years would be regarded to be the best available.

Power Vent vs. Direct Vent Water Heaters

When searching for a gas water heater, deciding on the sort of venting style to choose is an important consideration.Owning a power vent heater has some very distinct advantages and cons, which we explored in further detail in the preceding section.Despite the fact that there are some significant variations between power vent and direct vent water heaters, we must consider where the combustion (incoming) air is pulled in a power vent water heater in addition to the blower fan that aids with exhaust in a power vent.In contrast to a direct vent heater, which pulls combustion air from the atmosphere outside your home, a power vent heater draws combustion air from within your home.

Direct Vent

If you’re searching for a gas water heater, deciding on the sort of venting style to choose is an important consideration.A power vent heater has a number of distinct advantages and disadvantages, which we explored in further detail in the preceding section: We need to consider where the combustion (incoming) air is drawn in a power vent water heater because, while there are several significant differences between power vent and direct vent water heaters, we need to consider one more factor: the blower fan that assists with exhaust in a power vent water heater.In contrast to a direct vent heater, which pulls combustion air from the atmosphere outside your house, a power vent heater draws combustion air from within your house.

Power Vent

In a power vent water heater, the air necessary for combustion is drawn from the environment surrounding the water heater, and the surplus heat and exhaust are expelled through the venting system to the outside atmosphere by an electric blower fan mounted on the top of the heater.Power vent water heaters provide a number of advantages over other types of water heaters, including the ability to be vented vertically or horizontally and the ability to employ longer vent lines.When it comes to installation, this affords a great deal of versatility.Power vent heaters also have the advantage of using the heat from the exhaust to heat water, as well as emitting cooler exhaust, which allows them to use PVC pipe instead of metal venting.The power direct vent water heater, which is offered by some manufacturers, is a hybrid design that draws in incoming air from outside the home and exhausts the exhaust back outside.A blower fan is often used for both incoming and departing air, with the same motor and impeller.

• This is a fantastic alternative if your water heater needs to be positioned in a space where there is insufficient airflow for combustion to take place.

Can You Convert Regular Water Heaters to Power Vent Water Heaters?

Despite the fact that it is theoretically conceivable, we strongly advise against retrofitting a normal heater to a power vent system.Water heater warranties are nearly often voided when you attempt to convert a standard heating element to a water heater.The worst-case scenario is that it will void your house warranty, and in the event of a catastrophic breakdown, it may even cause a problem with your insurance claim.Rather than attempting to adapt an existing water heater, it would be in your best interest to acquire one from a quality brand such as Rheem or A.O.Smith that is intended specifically for this sort of venting in the first place.Water heaters were not meant to work in the manner in which they are now vented, thus altering the way they vent their exhaust places an additional burden on the heater.

• As previously said, this is not a do-it-yourself project, and if you are still seriously contemplating retrofitting your water heater, you should consult with a professional water heater installation to explore your alternatives.
• The safety of your family is not worth a few pennies in order to save money!

How Much Does a Power Vent Water Heater Cost?

Because power vent heaters have more components than their direct vent equivalents, they are often more costly than their direct vent counterparts.In general, you should expect to pay between $300 and $600 more for the power vent water heater itself, but you’ll also have to pay extra for the installation of the water heater.Keep in mind that if you don’t already have an electrical outlet close to the water heater, you’ll have to have one installed, which will increase the cost of the installation by another $100.In the end, the type of water heater you purchase will impact the amount of money you spend on it.It is important to note that power venting refers to the method through which exhaust gases from the water heater are evacuated from the surrounding atmosphere, rather than a specific type of water heater.Power vented water heaters are available in a variety of configurations, including tank and tankless types.

• Quality tankless water heaters are normally more expensive than tank-style systems, however there are certain manufacturers who sell units at a lower price point than the industry average.
• One example of a budget-friendly power vent tankless water heater is the Eccotemp FVI112-LP, which is an excellent choice if you need a tankless water heater for a vacation home, a compact home, or any other location with minimal water usage.

Are They Hard to Install?

In general, a power vent water heater is less difficult to install than conventional natural draft or direct draft water heaters of the same capacity.Because power venting does not rely on the inherent buoyancy of hot air, the vent pipes do not need to be routed higher as they would with conventional venting.Furthermore, because an exhaust fan is utilized to transfer the exhaust gases to the outside, the venting may actually run horizontally, making it easier to install.It is decided to utilize PVC pipe instead of metal venting since it is less expensive and much easier to build.The fact why PVC pipe may be utilized is due to the fact that the fan pumps cooler air into the system, diluting the hot exhaust gases.Considering that the final effect will be a cooler and more diluted exhaust, PVC pipe will be more than enough for the venting.

• When installing a power vented water heater, you should be aware of two installation considerations that are specific to this type of heater.
• You’ll need a regular electrical outlet close to the water heater so that you can power the blower fan, which is the first step.
• The second factor to evaluate is whether or not there is sufficient ventilation available to give make-up air.

Due to the fact that the fan will be drawing air from the environment surrounding the water heater, there must be sufficient ventilation to replace the air that is being drawn in by the fan.Despite the fact that power vent heaters are less difficult to install, you should check with your local building authority to determine whether you’ll need a permit before proceeding.In the event that you engage a professional plumber to complete the job for you, this will be included in the installation procedure.

An electric power vent water heater is, in general, less difficult to install than other natural draft or direct draft types of water heaters.Because power venting does not rely on the inherent buoyancy of hot air, the vent pipes do not need to be routed upwards as they do with traditional venting.Because the exhaust gases are removed from the building by means of a fan, the venting may be installed horizontally, making it simpler to install.A plastic pipe is utilized instead of metal venting, as it is less costly and much easier to put together.A major reason why PVC piping may be utilized is that the fan pumps cooler air into the system, so diluting the hot exhaust gases.PVC piping is more than capable of managing the venting since the final result is a cooler and more diluted exhaust.

• When installing a power vented water heater, you must be aware of two installation considerations that are very important to understand.
• You’ll need a regular electrical outlet next to the water heater so that you can power the blower fan, which will be the first step in this process.
• It is also important to make sure that there is sufficient ventilation available to give make-up air.

Due to the fact that the fan will be drawing air from the surrounding environment, there must be sufficient ventilation to replace the air that is being drawn in by the fan.Despite the fact that power vent heaters are less difficult to install, you should check with your local building authority to determine whether you’ll need a permit for your project.This will be included in the installation procedure if you hire a professional plumber to complete the task for you.

Is PVC an acceptable vent material for flue gases?

1. I just completed an inspection of the mechanical systems in student housing at a university in the Midwest.
2. In the school’s hundreds of apartments spread over a number of buildings, high-efficiency water heaters that were installed more than a decade ago were still in use.
3. A lack of hot water was said to be an issue, according to reports.

I discovered a high-efficiency water heater with purple/brownish PVC pipes and yellowish PVC flue pipe fittings, which I documented throughout my examination.The flue pipes had clearly been distorted as a result of the heat, and they were drooping.One of the university’s maintenance workers reported that some particularly poor pipes had fallen apart at the fittings and melted.This triggered the carbon monoxide alarm, which prompted a maintenance call to be placed.

The water heater had scaled up as a result of minerals in the water supply; as a result, the flue gas temperatures rose, resulting in the difficulties described above.Schedule 40 PVC pipe was used in this installation.We got a water heater installation handbook that advocated utilizing PVC pipe as a flue material; however, the producers of PVC pipe do not encourage doing so.I made a phone call to the manufacturer of the PVC pipe in this case and asked a few questions concerning the use of PVC pipe as a combustion flue for fuel gases with the representative.He was well-versed in this subject and promptly provided me a link to the company’s technical documentation, which described all of the piping’s physical and temperature restrictions.

He stated that the firm has had several complaints concerning the use of PVC pipes for venting flue gases, and that they constantly point out that they do not promote this use and that it is not included in their handbook as an option.He has contacted every major manufacturer of boilers and water heaters for statistics to substantiate the suggestions in their literature for the use of PVC pipe as combustion flue materials, but has gotten no responses to his requests for information.This is something that I am concerned about.The fact that a manufacturer promotes the use of PVC does not imply that it is suitable or safe to use.Just though PVC is effective in new installations does not rule out the possibility of a circumstance in which scale accumulates in a short period of time in hard water locations, causing high flue gas temperatures to develop.

• Most boiler and water heater manufacturers include other methods of venting using stainless steel in their documentation, but they always appear to promote the most cost-effective method in an attempt to make the boiler appear more economical to potential customers.
• The following information may be found in the PVC pipe technical manual provided by the pipeline manufacturer: Plastics are being used for combustion gas venting.
• If you have any questions concerning the appropriateness of plastic piping systems for venting combustion gases, the piping manufacturer suggests that you speak with the manufacturer of the water or space heating equipment that is being installed.

According to Section 503.4.1.1 of the International Code Council’s International Fuel Gas Code, plastic pipe and fittings used to vent appliances must be placed in accordance with the appliance manufacturer’s installation guidelines.As an added bonus, several of the ASTM standards that are relevant to PVC plastic pipe and fittings, and which this firm makes, include the following note: PVC pipe and fittings designed for use in the venting of combustion gases do not meet the standards of this standard specification for PVC pipe.Although many water heater and boiler manufacturers propose using a plastic flue vent for combustion flue gas pipe, there is no standard specified in any of the codes in the United States for doing so.Currently, only the ULC S636 Canadian standard is in use, and that standard has various problems, the most significant of which is that it enables flue gas temperatures to exceed those permitted by pipe material manufacturers.

As specified in the technical documentation of ABS, PVC, and Cpvc pipe manufacturers, the maximum temperatures mentioned below are indicative of their performance.Heat that is higher than the specified temperature will cause melting, sagging, and perhaps collapse or tear apart of the pipe.There are major implications to carbon monoxide asphyxiation and fire that must not be overlooked or minimized.According to industry standards, the stack temperature of a modern condensing water heater or boiler will be approximately 20 degrees higher than the water temperature.The stack temperature will be influenced by the design and efficiency of the unit, as well as a number of other parameters, such as the quality of the water.When a water heater is first installed, the flue gas temperature will be around 160 degrees Fahrenheit since the water heater is configured to hold water at 140 degrees Fahrenheit to prevent Legionella bacteria development.

• As scale accumulates and the heater’s effectiveness diminishes, the flue gas temperatures can readily rise to temperatures in excess of 350 degrees Fahrenheit.
• Even if a person’s water heater is set at 120 degrees Fahrenheit, the flue gas temperatures can soar to much beyond 300 degrees Fahrenheit when scaling occurs.
• Boiler thermostats or burner controls are typically limited to 200 degrees Fahrenheit, commercial water heater thermostats or burner controls to 180 degrees Fahrenheit, and residential water heater burner controls to 160 degrees Fahrenheit, with all of them having the potential to overshoot by a few degrees.

As scale accumulates on the heating surfaces, the scale acts as an insulator between the flue gases and the hot water in the system, raising the temperature of the flue gases as a result.In order to determine whether or not the boiler or water heater is scaling up and losing efficiency, certain boiler and water heater manufacturers include stack or flue gas temperature gauges, which are useful for monitoring the flue condition.It is possible to install a temperature sensor or probe with a high-limit control into the flue at the flue connection to the boiler or water heater and adjust the temperature from there.

If the temperature of the flue gas exceeds the temperature rating of the flue pipe, this control would switch off the burner and prevent any further combustion.In order to ensure the safety of plastic flue pipes, a standard will be required that includes a temperature gauge as well as a high limit probe.Then PVC, CPVC, and polypropylene flue gas pipes may be used safely on high-efficiency boilers and water heaters, as long as they are properly installed.This would provide a solution to the cost-versus-safety trade-off problem.In the absence of a standard for the correct use of these safety measures in conjunction with plastic flue gas pipes or without the use of stainless steel flues, plastic flue materials can melt when the temperature of the flue gas rises over a certain point.Not only does this result in energy loss, but it also has the potential to cause flues to become blocked or disconnected, posing a carbon monoxide or fire hazard.

In 2008, a family of four died in Aspen, Colorado, as a result of carbon monoxide poisoning caused by a breakdown of PVC plastic flue pipes on a condensing snow melting boiler system in a rental house.The cause of death was carbon monoxide poisoning.Since they had publicized limits on the usage of their pipes and had not suggested PVC pipe for that purpose, the plastic pipe manufacturer was not at blame in this case.The boiler manufacturer, who advised the use of PVC pipe as a flue material, was the object of a liability lawsuit filed by surviving family members against the company.PVC flue venting for combustion gases is not a problem, according to many contractors.

• However, I have seen melted and discolored piping in many of my investigations, so I am confident that it is a problem in many cases.
• The growth of recommendations for the use of flammable and unlisted PVC pipe items as corrosion resistant combustion flue venting from high efficiency, condensing boiler and water heater equipment manufacturers also concerns me.
• Installing a high-efficiency boiler or water heater appears to be a viable option for lowering the initial cost of the installation.
• Because high-efficiency equipment is substantially more expensive than less-efficient equipment, there appears to be a push among manufacturers to promote these unlisted and, hence, non-code-approved materials over corrosion-resistant stainless steel flues that are code authorized and listed.

Some individuals believe that following the manufacturer’s advice is permissible under the mechanical code, and this is correct.The following is the terminology used in the 2009 International Mechanical Code (IMC): 801.20 Vent Joints Made of Plastic Unless otherwise specified by the appliance manufacturer, all plastic pipe and fittings used to vent appliances must be fitted in accordance with those instructions.Vents in Section 802 (802.1) General.All vent systems must be identified and labeled in accordance with applicable regulations.Plastic pipe for flue gas venting applications is not included in the listing.

In addition, the 2009 IMC has the following language: The installation section is located in Section 304.2 Conflicts.The requirements of this code take precedence over any terms of listing or manufacturer’s installation instructions in the event of a discrepancy between the two sources of information.When a code provision is less stringent than the conditions of a product’s listing on the market or the manufacturer’s installation instructions, the terms of the listing and the manufacturer’s installation instructions will take precedence over the code provision in question.

It has been determined that sections 801.20 and 802.1 are in conflict.The installation instructions provided by the water heater manufacturer are in disagreement with the requirement in Section 802.1, which states that all vent systems must be identified and labeled for the application.Even though PVC pipe is not listed and labeled as a combustion flue pipe material, as noted in the piping manufacturer’s notes above, water heater and boiler manufacturers appear to be avoiding the issue, and they continue to recommend that PVC flue venting be used in their installation instructions.Section 304.2 deals with the issue of disputes.Due to the more rigorous language used in the code limitation requiring all flue materials to be listed and labeled for their intended use, the more stringent code requirement requiring listed and labeled flue pipe materials would be applied.

In the International Fuel Gas Code, there is extra wording to consider.Neither a boiler nor a water heater manufacturer has provided me with any testing data nor an independent test report which demonstrate that PVC pipe has been tested and authorized for the circumstances that it is expected to encounter in a water heating or boiler installation.Any testing should cover the severe circumstances that occur at the end of the equipment’s service life, when scaling occurs and flue gas temperatures climb dramatically.Specifically, the Canadian standard, ULC S636, addresses the design, installation, and operation of gas venting systems intended for negative or positive pressure venting of gas-fired appliances producing flue gases with temperatures between 0°C and 400°C.1.Class I venting systems are suitable for gas-fired appliances that produce flue gas temperatures greater than 135 C (275 F) but less than 245 C (473 F); 2.

• Class II venting systems are suitable for gas-fired appliances that produce flue gas temperatures less than 135 C (275 F); 3.
• Class II venting systems are further classified into four temperature ratings as follows: 1.
• Class I venting systems are suitable for gas-fired appliances that produce flue gas temperatures greater than 135 C (275 F) (A) Up to and including 65 degrees Celsius (149 F) This temperature limit was set in order to allow the use of PVC pipe as a flue gas material in certain circumstances.
• The temperature limit for PVC pipe is 140 degrees Fahrenheit, and the maximum allowable temperature specified in the ULC S636 standard is higher than the temperature limits established by PVC pipe producers.
• (B) Up to and including 90 degrees Celsius (190 F) The purpose of this temperature limit was to allow the use of CPVC pipe as a flue gas material in certain circumstances.
• The temperature specified in the pipe manufacturer’s technical data is 180 degrees Fahrenheit.

The ULC S636 standard allows the material to be used in applications where the temperature limit for CPVC piping is exceeded by 10 degrees Fahrenheit.(C) Up to and including 110 degrees Celsius (230 F) When this temperature limit was set, it was intended to allow the use of polypropylene (PP) pipe as flue gas material in certain applications.Although just one manufacturer is now recognized as adhering to this criteria, the possibility of flue gases exceeding 230 degrees Fahrenheit still exists.It would be advisable to install a high-limit switch to shut down the boiler or water heater.

1. (D) Up to and including 135 degrees Celsius (275 F) I am not aware of any plastic pipe manufacturers who are in compliance with this sub-section of the specification.
2. The possibility of flue gas temperatures exceeding 230 degrees Fahrenheit remains a possibility.
3. It would be good to install a high-limit switch to shut off the boiler or water heater.
4. On this issue, it will be interesting to see which way the indus
