What Is A Power Vented Water Heater

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.

What is a Power Vent Water Heater?

In order to remove potentially dangerous combustion emissions from your home, gas water heaters require venting. The two most typical venting options are direct vent and power vent. Direct vent is the most common. 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.

Another advantage is the reduction in energy use.

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.

Because they are “tightly constructed,” it might be difficult to create a satisfactory natural airflow for ventilation in these structures.

Disadvantages

A power vent water heater, like any other appliance, has its downsides, which are listed below. To begin with, they make a lot of noise. 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.

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.

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 vents and direct vents, Beyond the blower fan that aids with exhaust in a power vent, we need to look at where the combustion (incoming) air is pulled in water heaters to determine their efficiency.

Direct Vent

A direct vent water heater, in contrast to a conventional water heater, pulls air from the surrounding environment for burning. The exhaust gases, as well as any surplus heat generated during the process of heating the water, are then vented to the outside. Special coaxial venting is utilized to split the entering and departing air, allowing for the use of a single vent rather than two in order to save space. To prevent backdrafting, the venting goes horizontally through the side of the house and draws and pushes air outside.

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.

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.

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. Water heaters intended for power venting are available from most premium manufacturers, includingRheeman and A.O.

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.

You should avoid taking on this job on your own. If you are still contemplating retrofitting your water heater, you should speak 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!

What’s the Best Power Vent Water Heater?

If you’re ready to make the investment in a power vent water heater, you have a plethora of choices. The majority of water heater manufacturers provide power vent heaters as part of their product lineup. Here are a handful of the greatest options now available on the market.

A.O. Smith 50-Gallon ProMax Power Vent

The A.O. Smith GPVL-50 ProMax Power Vent is a high-performance power vent. A gas water heater with a capacity of 50 gallons is a good alternative. An A.O. Smith heater is almost impossible to go wrong with, and this water heater is no exception to that rule. Improved energy efficiency is achieved via the use of a cutting-edge electronic gas control, a Dynaclean II dip tube, and 2-inch thick ecologically friendly insulation. One distinctive feature of the GPVL-50 ProMax is the 3-position rotatable blower, which allows you to work in a variety of positions.

Rheem 50-Gallon Power Vent Water Heater

With an energy efficiency rating of.67 and a first hour rating (FHR) of up to 87 gallons, the RheemPROG50-42N 50-gallon power vent water heater provides excellent performance for a tank with a capacity of just 50 gallons. It makes use of a low Knox design, an environmentally efficient burner, and an electronic gas control. If you’re in the market for a 50-gallon water heater, Rheem is a well-known and high-quality manufacturer, and this is a good option. Water heater with a capacity of 50 gallons from Rheem

American Standard Tankless Natural Gas Water Heater

The American Standard TCWH199S-AS-NG is a national standard. is a natural gas power vent water heater that does not require a tank. It has an excellent 96 percent efficiency rating, as well as a sturdy construction that includes two heat exchangers made of 304-grade stainless steel to ensure long service life. It’s reasonably priced for a gas tankless heater, and with good care and maintenance, it should be able to provide service for 20 years or more without needing to be replaced. Tankless water heaters by American Standard

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.

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.

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.

Eccotemp FVI112-LP is a wonderful example of a power vent tankless water heater that is both affordable and efficient. It is a perfect choice if you need a water heater for a vacation house, a tiny home, or any other low-use setting.

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.

  • Considering that the final effect will be a cooler and more diluted exhaust, PVC pipe will be more than enough for the venting.
  • 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.
  • 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.
  • A skilled plumber will take care of this for you, and it will be included in the cost of the installation service.

Get Help Installing Your Power Vent Water Heater

It is one of the most crucial items in your home, and it is the water heater. You should carefully follow the manufacturer’s installation instructions if you decide to acquire a new power vent water heater. It is possible that failing to do so may result in countless hassles in the future. With this in mind, you might want to consider hiring a plumbing specialist to help you with the installation procedure. They’ll have the knowledge and experience to guarantee that your power vent water heater is properly installed and configured to last for many years.

Differences Between Direct Vent and Power Vent Water Heaters

We at Haley Mechanical recognize that, given the variety of terminologies used to describe water heaters, selecting the most appropriate one might be difficult to determine. There are several varieties, and deciding which is the most appropriate for your scenario might seem like an intimidating undertaking at first. Direct vent and power vent water heaters are two of the most common types of water heaters on the market today. A power vent water heater removes combustion gases from the environment by the use of a powered venting fan, whereas a direct vent water heater vents combustion gases into the external atmosphere through the use of a chimney or exhaust pipe.

Direct Vent Water Heater

When you use a direct vent water heater, the water is heated by the heat generated by the combustion of the fuel.

In most cases, a direct vent system results in cheaper water heating expenses than a power vent system since the exhaust gases are vented vertically rather than horizontally, and no additional power is required, as is the case with the power vent water heater.

Power Vent Water Heater

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. 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. Some places do not have access to a chimney or vertical vent, which means your options are restricted in these situations. When using a power vent, the key advantage is that the water heater may be installed almost anywhere because it does not require a vertical vent or chimney.

  1. 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.
  2. The disadvantage of this type of water heater is the overall cost, which includes the cost of the blower/fan element of the vent, which requires energy to function, as well as the cost of the actual blower or fan and the expense of installing a power connection to the blower or fan.
  3. Power vents have another disadvantage: they produce a tiny sound, which some homeowners notice, when the blower or fan operates while the hot water heater is in operation.
  4. When correctly placed, noise may be reduced to a bare minimum, if not completely eliminated.
  5. 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.
  6. We at Haley Mechanical can assist you in determining which type is most appropriate for your individual scenario and budget.

What is a Power Vent Water Heater?

Power vent water heaters, which are equipped with built-in fans that push the exhaust gas out of the vent through a powered fan, have quickly become the standard for newly constructed homes. Power vent water heaters have become the industry standard for newly constructed homes because of their efficiency. It is practically hard to backdraft a power vent water heater because of the way they are constructed. If you have a power vent water heater installed, you will have a considerably decreased likelihood of experiencing carbon monoxide problems as a result of your water heater.

The majority of these gases are made up of water vapor and carbon dioxide.

In order to maintain the structural integrity of your water heater unit, power vent systems are a great choice.

AdvantagesDisadvantages of Power Vent Water Heaters

Power vent water heaters, like all other water heater systems, have advantages and disadvantages that may be considered when deciding whether or not such a system is appropriate for your house. Before making the conversion to a power vent water heater, take the following factors into consideration:

  • Water heater backdraft: As previously stated, power vent water heaters are nearly difficult to backdraft, therefore safeguarding your house from the possibility of carbon monoxide poisoning from your water heater. Electric power vent water heaters are well-known for their energy efficiency, consuming less fuel than other types of accessible venting systems. Rather than utilizing a vent that runs through the centre of your home, power vent manufacturers allow for longer runs on the vent, enabling you to install the unit nearly wherever in your home that is most convenient for you. In terms of performance, power vented water heaters can supply hot water more quickly than other solutions. Homeowners may experience difficulties with noise because these systems are noisy straight out of the box and do not become any better with time. Electricity: Because power vent water heaters must be connected into an electrical outlet, they may need the construction of electrical outlets, increasing the cost of initial installation. Cost: On average, power vent systems are around 75% more expensive than alternative venting systems. Guarantee: When compared to other units, these devices have a significantly shorter warranty duration, with the majority of them having a warranty of only six years.

You may obtain expert advice from a local specialist if you’re still unclear whether a power vent water heater is the best option for your household.

Direct Vent vs. Power Vent Water Heaters

There are several varieties of water heaters available, making it overwhelming and difficult for homeowners to choose which type of water heater would be the greatest fit for their home’s requirements. We will discuss the two most prevalent types of water heaters in this section: direct vent and power vent. The difference between the two types of water heaters is the amount of fuel that is burned from the burner to the vent system. A direct vent water heater vents these combustion gases to the atmosphere, but a power vent water heater eliminates them with the use of a powered venting fan, which is included with the water heater.

Two Different Types of Water Heaters: DirectPower Vent

Especially in the Northern Colorado area, direct vent water heaters are highly popular. Fuel is burned in a direct vent water heater and the heat generated by the combustion process is used to heat the water. The exhaust gases are subsequently vented to the exterior of the home through the exhaust pipe or chimney, depending on the model. Direct venting is effective because warm air is lighter than cool air, and as a result, it will naturally rise as a result of the difference in buoyancy between the hot and cold air temperatures.

A basic technique that works well when the exhaust gases can be vented vertically is the one being discussed here. A reduction in overall hot water heating expenses is achieved by eliminating the requirement for additional electricity.

Power Vent

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. 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. With the help of a fan or blower, exhaust gases may be forced through horizontal exhaust pipes and out the other end. The flexibility to position a power vent water heater away from a chimney is the primary advantage of using a power vent water heater.

It is more popular in some regions of Northern Colorado, such as the Loveland, Fort Collins, and Longmont areas, for this kind of water heater to be installed.

Disadvantages

When using a power vent water heater, a fan or blower is used to help in the evacuation of exhaust gases from the hot water heater’s combustion chamber. It is possible that a power vent water heater will be your only option if your water heater is situated in an area where there is no access to a vertical vent or chimney. With the use of a fan or blower, exhaust gases may be forced into horizontal exhaust pipes. The flexibility to position a power vent water heater away from a chimney is the primary advantage of using a power vent water heating system.

If there is no chimney available, horizontally venting the water heater to the exterior using an affordable venting pipe will be an option.

Resources

Not all A. O. Smith water heaters require venting within your house, but if you have a gas water heater that does require venting, it’s critical that you use the proper venting material to ensure that the water heater operates safely. Selecting the proper venting for your water heater can assist to guarantee that it performs safely and effectively. Because you may not be aware of the type of vent that your water heater requires, you should call a professional plumbing contractor to assist you in determining the best option for your property.

Standard Atmospheric Vent

Standard atmospheric water heaters are the most popular form of gas water heater used in residential settings. In order to escape the residence, atmospheric gas water heaters must exhaust their exhaust through a vertical or upward sloping metal duct vent. This venting can be devoted to the water heater or it can be shared with other atmospheric vent appliances, such as a furnace, depending on the situation. The principle of atmospheric venting is based on the rise of heated air. This means that the venting must be vertical or upward sloping in order for the hot exhaust to ascend through the venting and out of your home.

Any obstructions or misalignments in your home’s ventilation system may result in the discharge of excess heat and gases into the surrounding environment. It is recommended that you hire a competent plumbing contractor to do the installation.

Power Vent

A. O. Smith is a fictional character created by American author A. O. Smith. The electric blower fan on the top of a power vent gas water heater necessitates the installation of an electrical outlet adjacent to the water heater since power vent gas water heaters are equipped with an electric blower fan. The blower is responsible for pushing exhaust and extra heat through the exhaust venting system. Power vent water heaters may be installed either vertically or horizontally, with a longer line to accommodate concerns with space and dimensions in your home.

Power vents are a more energy-efficient alternative since they are intended to use the heat generated by the exhaust to heat water, resulting in significant energy savings.

It is recommended that you hire a competent plumbing contractor to do the installation.

Power Direct Vent

A. O. Smith is a fictional character created by American author A. O. Smith in the 1960s and 1970s. The electric blower fan on the top of a power vent gas water heater necessitates the installation of an electrical outlet adjacent to the water heater since the fan is powered by electricity. The exhaust and extra heat are forced via the exhaust venting by the blower. Power vent water heaters are more versatile to install since the venting may be extended either vertically or horizontally with a longer line to deal with space and sizing difficulties within your home.

Because of the lower exhaust temperatures, PVC pipe may be used instead of normal atmospheric vent metal piping, which is both less costly and easier to build than the latter.

Direct Vent

Insufficient ventilation in the installation space of your home makes direct vent gas water heaters the most suitable choice of gas water heater. In contrast to an indirect vent water heater, a direct vent water heater takes air for combustion from outside your home rather than from within. All of the exhaust gases and surplus heat generated by your water heater are vented back into the environment. A direct vent water heater makes use of specific coaxial venting, which features separate chambers for intake air and exhaust air in a single manufactured vent component, which allows for more efficient operation.

They draw and push air from the outside to ensure that there is no backdrafting within your home or building.

When installing and utilizing a gas or liquid propane tank water heater, this can assist to reduce the chances of injury or death. It is recommended that you hire a competent plumbing contractor to do the installation.

Concentric Vent Termination

In a coaxial “pipe in pipe” venting system, concentration refers to a configuration in which both the intake air and the exhaust gas vent through a single common assembly. It is possible to achieve an aesthetically pleasing installation with only a single wall or roof penetration. Concentric venting may be utilized with a variety of water heaters, including direct vent, power direct vent, and tankless water heaters. Direct vent water heaters are the most common. The material of the concentric venting, on the other hand, may change depending on the type of water heater being used.

On a power direct vent tank or tankless water heater, a concentric vent termination can be utilized to achieve the same benefits of a single wall or roof penetration while maintaining an aesthetically pleasing vent termination.

It is recommended that you hire a competent plumbing contractor to do the installation.

How to Install a Power-Vented Water Heater

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 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.

  • 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.
  • It’s best if you leave it to the professionals.
  • 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.
  • 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. You must have a normal electrical socket near the unit to supply power for the fan
  2. You must ensure that you have an appropriate supply of “make-up” air to replace the air that is being blown out
  3. And you must ensure that the machine is properly ventilated. 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
  4. 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.

Power Vented or Gravity Vented Water Heater: Which Do I Need?

Even though water heaters are an absolute necessity in any family, there are so many different varieties available that it may be tough to determine which one is appropriate for your new home. Do you require a tank or a tankless water storage unit? And what kind of size do you think it should be? Is it better to use natural gas or electricity? The answers to all of these concerns should be discussed with a water heater installation specialist; however, one subject that many consumers are unaware of is whether they require a gravity vented or a power vented water heater.

Gravity Vented Water Heater is The Most Common

When it comes to gas-fueled water heaters, the gravity-vented water heater is the most prevalent type. There will be some plumbing installed to link the unit to an exhaust pipe or chimney, and a typical gas-fired storage tank water heater will be installed. There must be a destination for the combustion gases produced as a by-product of heat generation, otherwise they might provide a fire danger or threaten to pollute the surrounding environment.

Power Vented Water Heater

Power vents are less frequent and may be more expensive to install at first, but they provide a number of advantages over other types of vents. They will not be required to be connected to a vent pipe or chimney, which makes them perfect or critical for certain home designs and siting options. As an alternative, they exhaust combustion gases through a vent that is mounted directly to the wall near the heater. Existing vent pipes can sometimes limit the size of water heaters that can be placed, but with power vents, the vent can be configured to be large enough to support any size water heater that is being used at the time.

Installed incorrectly, or if your installer attempts to connect it to the chimney or an existing vent pipe, it has the potential to cause a fire or carbon monoxide poisoning in your house.

It can be difficult to choose which sort of water heater you require, and a skilled professional is the best person to determine what is appropriate for your house. Call Advantage Airtech if you want to find out more about gravity vented units or power vent installation in Whitby.

Venting types

There are two types of tanks available: tank-type and tankless. The following venting options are available: atmospheric, direct vent, power vent, and power direct vent (for power direct vent).

What are the power vent water heaters?

Model with a Power Vent Power vent water heaters (PV) are constructed with an electric-powered fan positioned on the top of the device, which allows for better ventilation. As a result of the blower’s help, combustion gases are mechanically pushed to the outside while fresh air is forced in from the inside. A fan’s pressure reduces the likelihood of negative pressure building up within the house, while simultaneously improving the quality of the air. In addition to being factory installed, the vente pipe is sealed, allowing for lengthy lengths, and other than the installation of the venting pipes, no additional work will be required to complete the installation.

Forced-draft or fan-assisted water heaters are other names for power vent water heaters.

Differences between atmospheric and power vent models

The simplest of these four venting kinds is atmospheric venting, which is often referred to as the normal type of venting. A chimney or vertical flue is used to effectively move the products of combustion outdoors when using natural airflow (buoyancy effect). Positive pressure can build in the household, causing flue gases to be drawn back into the house, increasing the danger of carbon monoxide exposure for those living there. This sort of water heater is often less efficient, but it is also less expensive to purchase.

Differences between direct and power vent models

Direct vent water heaters (DV) are similar to power vent water heaters (PV) in that they use a sealed combustion chamber but do not include an electrically controlled fan or blower, as do power vent versions (PV). Their venting system, which may be either solid or flexible, is designed to send the combustion products outside and into the surrounding environment, as seen in the illustration. They draw in fresh air from the outside using an air intake pipe, which can be either a single or a dual-pipe configuration.

Direct vent water heaters are those that exhaust gases through a horizontal vent pipe without the need of a fan or electricity, as opposed to those that use both.

Direct venting is also an option, although it is less efficient.

When compared to the two types of water heaters mentioned above, power vent water heaters are more advanced, cost more, and provide more benefits, such as higher energy efficiency – resulting in greater savings, venting flexibility – allowing for easier installation, and no problems associated with back-drafting.

Power vent water heaters – Things to consider

  • Purchase a power vent water heater (PV) if you want to replace an outdated electric water heater with a high-efficiency gas water heater. When there is no access to a chimney or vertical vent, or when the ordinary atmospheric model cannot be utilized, or when a house is densely packed together, the PV water heater should be used. The PV versions should be used when installing a water heater, whether it is close to or far away from an outside wall, due to the long pipes and blower that provide proper venting. Installation near an electric wall outlet (often 120 V) is recommended due to the fact that the device cannot function without electricity.

When deciding where to install your PV water heater, keep in mind that it will need to be close to the intake and exhaust vent systems as well as the combustion air supply. The venting system must be installed in accordance with the manufacturer’s specifications and must meet all applicable local standards. From the water heater to the termination, it must be able to be run with the shortest possible length and the smallest possible number of elbows. Make an appointment with an expert for a safe, professional, and worry-free installation.

Popular manufacturers of power vent water heaters

If you are searching for an energy-efficient water heater that employs the power vent and is manufactured by a well-known US or Canadian company, the following are some suggestions: AO Smith, Bradford White, and Rheem are three of the most well-known names in the industry.

AO Smith

Power venting is used in over 20 distinct models from AO Smith, and both natural gas and propane gas are used. The low NOx burners are used in the majority of the models, with only two models using ultra-low NOx burners. Almost all of the power vent water heaters are from the ProLine XE series, with only one being from theVertexseries, which happens to be the most energy-efficient and best model to buy. The various sizes range from 40 to 75 gallons, with the 50-gallon unit being one of the most widely used and most widely accessible.

Installing a power vent water heater

The vent pipe for power vent water heaters can be terminated either horizontally through an outside wall or vertically through the roof, provided that it is supported adequately along its length. There are two types of venting options for your water heater that you should consider: The concentric system (coaxial), which is a pipe inside a pipe, can be used to establish a single vent pipe system. In this case, one pipe is used as a discharge and the other is utilized as an intake pipe. When the internal air is utilized for combustion, it is necessary to provide a designated area with access to sufficient supply of fresh air to ensure proper combustion.

These can be either horizontal or vertical in orientation.

Provide a downward slope for horizontal termination in order to avoid possible condensate from re-entering the system and interfering with the blower’s functioning.

Providing enough air ventilation must be made when it is positioned in a limited location is a legal requirement.

Venting tips

Purchasing a venting kit from the manufacturer or a supplier ensures a worry-free installation because they are compliant with all applicable standards and safety regulations. In order to appropriately design the system, consult the manufacturer’s handbook and model specifications to establish the BTU rating of the system, the model, the venting lengths, and any other needs. Plastic pipes, for example, cannot be used in non-condensing tankless water heaters; only stainless steel may be used in these applications due to the acidic nature of the combustion products.

  • In addition, they are featured in condensing tankless units.
  • When building the air inlet and vent outlet, it is critical that both pipe diameters are the same size as one another.
  • In any vent installation, a certain number of elbows is suggested, however this number varies depending on the length of the vent.
  • There should be no diminution in the diameter of the vent pipe, and it should be vented as directly as feasible.
  • When placed in a building, power vent water heaters cannot be connected to the chimney and shared with other appliances due to the severe depressurization that will occur, which would adversely impair the performance of other gas-burning appliances in the building.

For the purpose of connecting the vent to the blower, a rubber coupling and gear clamps are included with the water heater. These connections must be properly sealed in order to prevent the leaking of combustion products into the living space.

Required tools

  • Power vent kit or PVC pipe and fittings are both options. Adjustable wrench, drill, saw, screwdriver, level, pliers, multimeter, PVC tube cutter, caulk gun, electric wire, and other miscellaneous tools

Drawbacks

You should be aware of the following disadvantages:

  • There are numerous disadvantages to be aware of:

Conclusion

Installation of the power vent pipe system by a qualified professional, with clear combustion and ventilation air supply, is essential for the safe and effective functioning of the system for many years to come. The PV type is recommended for households that do not have access to a chimney and where energy-efficient heating is necessary for comfort.

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

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, you’re likely to find yourself thinking about your water heater quite a bit.

  • Rushing this choice, on the other hand, would be a mistake.
  • 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.
  • “Taking your time” is a good idea for a variety of reasons.
  • If you don’t, you’ll almost certainly wind up spending more for installation than is actually necessary.
  • 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.

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.

  • An atmospheric venting system is one in which the exhaust from a water heater naturally rises out of its combustion chamber and goes up via a typical, chimney-style flue that terminates on the roof of the house or 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
  • Direct venting and power venting systems both provide greater freedom because neither requires a direct route to the roof, allowing for more creative design. 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

Even if you want to update to a water heater that vents in the same manner as your previous one, O’Brian suggests talking with a professional. When dealing with potentially fatal gases, it may seem like a basic exchange, but as O’Brian points out, “even slight leakage may be disastrous when dealing with potentially lethal gases.” To put it another way, don’t take any chances. Carry out your study, select an energy-efficient unit with a capacity that suits the demands of your family, and then leave the rest to the HVAC installation.
