When to Use a Power Vent Water Heater (Incl. Review of Rheem 50 Gal)

  • If you’re on the market for a new water heating solution, you’ll almost certainly come across devices that use power vent technology.
  • Because of the multiple advantages it provides, a power vent water heater has become one of the most popular alternatives for residential usage.
  • When selecting a new water heater to install, you’ll want to make sure that you get the one that is appropriate for your area and demands, as described above.
  • In this section, we will discuss what one is and when one should utilize one.

What is a Power Vent Water Heater

  • Power and direct vent water heaters are the two types of vent water heaters that are available.
  • Essentially, your heater will emit dangerous combustion fumes that must be expelled from the house as quickly as possible.
  • The difference between these two types of heaters is the sort of venting mechanism that is employed.
  • The location of the venting on a power vent water heater is different from the location of the venting on an earlier direct vent water heater.
  • Direct vent types can only be installed in conjunction with your home’s chimney, where the gasses are released vertically from the furnace.
  • An exhaust pipe is used in conjunction with a power vent model to allow the vents to exhaust horizontally.
  • Unlike the chimney, this does not have to be attached to the building and can be directed anywhere outside the structure.
  • ‘Power’ refers to an extra fan or blower that is used to drive the exhaust gases out of the system.
  • When using these sorts of water heaters, the blower will always require a separate source of electricity to operate.

Occasionally, you will have a gas water heater, but you will still want an electrical connection for the venting system.

When to Use a Power Vent Water Heater

  • Power vent water heaters, like any other appliance that is put in your home, have their advantages and disadvantages.
  • When utilized in the appropriate place and fitted properly, these models are fantastic choices.
  • For starters, and this is the most essential thing to remember about these heaters, their venting mechanism allows them to be installed almost anyplace.
  • The installation of a direct vent heater is limited to areas with a chimney, but power vent heaters may be put almost everywhere.
  • Nothing more than a horizontal pipe to run out of the heater will be required in this location.
  • Aside from that, they may be simply included into the style of your house.
  • In this case, power vent versions are an excellent option if you do not have access to a chimney or if the heater must be installed in an awkward location.
  • Additionally, the use of an electric fan or blower to vent the exhaust gases is an advantage of these versions as well.
  • As a result, the risk of backdrafting is much reduced, making these units significantly safer to have around the house.

Unfortunately, a power vent type will require a source of electricity, therefore they will need to be installed in an area where they will have easy access to one or more power outlets.Because of the fan, these versions can also be a little louder than other models from time to time.In order to do this, they are frequently best suited for placement in locations that are a little separated from the main living spaces.

Differences Between Direct Vent and Power Vent Water Heaters

  • We at Haley Mechanical recognize that, given the plethora of names that are used to describe water heaters, selecting the most appropriate one may be challenging.
  • 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.
  • There are several possibilities here.
  • 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.
  • Whatever method is used, a power vent may be ventilated by simply extending cheap pipe horizontally across the room.
  • 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.
  • Essentially, because the power vent requires the usage of a fan/blower to operate, the expenses of heating water will be greater over the course of the power vent’s useful life.

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.For the majority of individuals, the noise is not very apparent or annoying; nonetheless, it is something you should be aware of if you are considering installing this sort of vent in your home.When correctly placed, noise may be reduced to a bare minimum, if not completely eliminated.It is evident that a power vent hot water heater will be more expensive than a direct vent hot water heater, but in some cases, it is just not possible to avoid installing a power vent hot 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.


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.

  1. In this circumstance, a power vent water heater may be a smart alternative to consider.


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.

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

While conventional water heaters burn the air that surrounds the device, a direct vent water heater takes air from the surrounding environment outside your home to burn.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.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.

  1. 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.
  2. In the event that you engage a professional plumber to complete the job for you, this will be included in the installation procedure.

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: Direct & Power Vent

Direct 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.

If a chimney is not accessible, horizontally venting the water heater to the exterior using a cheap venting pipe will also benefit the homeowner by allowing him or her to save money on the water heater installation.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.


Because of the additional equipment required, such as the fan and blower, a power vent water heater will be more expensive to purchase initially.Additionally, you will need to install a power line to the fan, which will add to the overall cost of the project.Another disadvantage is that the blower element of the water heater will require power to run, increasing your hot water heating bills over the course of the water heater’s lifetime.The sound of the fan running when the hot water heater is in use is also a source of complaint for some individuals, as previously mentioned.

Despite the fact that it is probably only a minor risk, it is something that should be taken into consideration.Proper installation can assist to eliminate or reduce the severity of most of these problems.Whichever water heater is best for you will be determined by your location in relation to access to a vertical vent (vent stack) passage or chimney.

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.When installing a normal atmospheric vent with your water heater, it is critical to ensure that your property has a fully functioning vent system.Any obstructions or misalignments in your home’s ventilation system may result in the discharge of excess heat and gases into the surrounding environment.

We recommend that you seek the services of a competent plumbing contractor for the installation process.

Power Vent

Water heaters from A.O.Smith with a power vent are equipped with an electric blower fan, which is mounted on top of the water heater and requires that an electrical outlet be located adjacent to the water heater.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.As a result, they are more versatile in their installation than other types of water heaters.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.

Because of the lower exhaust temperatures, PVC pipe may be used instead of typical atmospheric vent metal piping, which is both less costly and easier to build than standard atmospheric vent metal.We recommend that you seek the services of a competent plumbing contractor for the installation process.

Power Direct Vent

In situations when there is insufficient air for combustion in the space in which you are putting a water heater and you want flexibility around the installation, power direct vents are employed.Before proceeding with this installation, consult with a skilled plumbing contractor to ensure that you require power direct venting.Power direct venting is similar to direct venting in that it employs a blower to draw in air from outside your home for combustion and deliver it straight to your water heater, similar to the way direct venting works.

  1. The same blower is also utilized to vent the combustion exhaust gases outside of your home once they have been expelled inside.
  2. A power direct vent water heater, which is similar to the power vent design, may be installed with PVC pipe to save money on installation expenses.
  3. It is vital to remember that they must be installed near a water heater where there is an electrical outlet.

Direct Vent

Water heaters that are vented directly into the atmosphere are the most suitable for usage in situations when there is inadequate ventilation available within the installation area of your home.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.

  1. 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.
  2. The water heater’s venting is sent through the side of your house to the outside.
  3. They draw and push air from the outside to ensure that there is no backdrafting within your home or building.
  4. When installing and utilizing a gas or liquid propane tank water heater, this can assist to reduce the chances of injury or death.
  5. We recommend that you seek the services of a competent plumbing contractor for the installation process.

Concentric Vent

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.

  1. Direct vent water heaters are the most common.
  2. The material of the concentric venting, on the other hand, may change depending on the type of water heater being used.
  3. Direct vent water heaters and concentric vent tankless water heaters are examples of devices that are specifically intended for concentric venting and may be utilized to complete the whole vent line (from water heater to exterior of the home) in a single installation.
  4. 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.
  5. Separate intake and exhaust vent pipes are run between the water heater and the inside wall in that installation, with only the wall penetration and termination utilizing concentric plumbing throughout the rest of the system.
  6. We recommend that you seek the services of a competent plumbing contractor for the installation process.

Direct Vent vs Power Vent Water Heaters: The Differences That Matter

With so many products available on the market, it can be difficult to make a selection, especially when looking for spec-heavy electrical items such as water heaters that have a lot of features.Many different variants and brands are available to you, each with its own set of characteristics from which you may choose what you want.However, there is one problem.

  1. Is it better to go with a direct vent unit or a power vent unit for your home?
  2. If you haven’t thought about it yet, we’ll go over all the facts, as well as the advantages and disadvantages of each method, so you can make an informed decision.
  3. Power vents may be the only realistic choice in certain homes because of the position of the water heater, or they may be the only option in some homes since there is already a direct vent device in place.
  4. Throughout this post, we’ll go through the specific pros and downsides of each system in depth.

Difference Between Direct Vent & Power Vent Water Heaters 

Simply simply, water heaters require some type of energy to heat the water they produce.In the case of water heaters, it is given by the combustion of fuel.It is necessary to release the gases created during burning into the environment.

  1. In order to do this, two options are available: a direct vent system and a power vent system.
  2. The primary difference between the two is that in a direct vent water heating system, the combustion gases are discharged into the atmosphere through chimneys and exhaust pipes, whereas in a conventional water heating system, they are not.
  3. In contrast, the combustion gases produced by water heaters are evacuated by the use of powered venting fans in the power vent system.
Direct Vent Power Vent
Mostly used in old homes Seen in relatively new homes
Uses chimneys and exhausts to remove combustion gases Uses power-driven fans to remove combustion gases
Has restrictions in terms of placement of the water heater The water heater can be placed anywhere
Installation cost is lower Installation costs can be high

Direct vent water heater systems do not require any additional electricity since they rely on chimneys to function, and the water heating costs can be cheaper than those associated with power venting systems because they do not require any more power to function.However, this restricts the placement of direct venting water heaters since the chimney or vents must be put vertically and cannot be installed in areas that do not have direct access to the chimney.Direct venting water heaters are also more expensive to install.

  1. The use of power vent water heating systems, which can be installed anywhere in the home, eliminates the need for these types of issues.

Direct Vent Water Heaters

Direct Ventilation Water heaters draw their energy from the air outside your home, which is drawn from the atmosphere, while the exhaust gases and excess heat produced are vented outside the property through chimneys and vents.Many direct vent water heaters are equipped with coaxial venting, which allows the entering and exiting air to be separated from one another.The venting extends horizontally down the length of the home and sends the air outside to avoid the air from being drawn back into the house.

  1. This enables the direct vent system to use a single vent for both processes rather than having to install two separate vents for each process as previously required.
  2. By using direct venting, you may take advantage of the fact that hot air naturally rises higher than cold air owing to the difference in buoyancy of the two types of air.
  3. Vertical venting allows the system to operate at peak performance without requiring additional power consumption.
  4. As a result, the overall running cost of the water heater is reduced.
  5. Let’s take a look at the advantages and disadvantages of a direct venting water heater installation.


  • For older homes with a chimney, installation methods are simple, and the initial expenditures are minimal.
  • When it comes to the transport of air, no more power is required.
  • As a result of the reduced amount of moving components, it does not generate additional noise.
  • Maintenance costs are reduced.


  • This places restrictions on the location of the water heater since it requires direct access to vents or chimneys.
  • Incomplete combustion can occur if the sufficient amount of air is not provided.

Power Vent Water Heater

Power vent water heaters make use of a fan or blower that is powered by electricity to ease the passage of hot air outside the residence.This is quite convenient since it allows the user to locate the water heater anywhere in the house without having to worry about connecting it to the chimneys.By utilizing power vents, it is possible to move hot air even via horizontal ventilation openings.

  1. This is quite handy for contemporary dwellings, but it may necessitate the installation of elaborate ventilation systems in order to exhaust the gases.
  2. Aside from that, many homeowners use such heaters for the purpose of removing exhaust gases and increasing their house’s safety factor.
  3. Because of the mechanical pressure supplied by the power vent water heaters, the danger of a backdraft of air is eliminated.
  4. Hazardous gases such as carbon monoxide, which are typical consequences of incomplete combustion, are less likely to escape from the vents and cause poisoning, as a result.
  5. The majority of new homes are constructed with energy efficiency in mind.
  6. As a result, the positioning of water heaters, as well as the potential of natural venting, is frequently compromised.

In many cases, a power vent heater may be the only alternative available in a home.However, like with many wonderful things, power vent water heaters have their own set of downsides and disadvantages.The most significant is the addition of an additional motor, which can increase both the overall amount of power consumed and the cost of installation.The additional fan creates another annoying issue, which is the noise produced by the motor when it is running.It will not be an issue in most circumstances, but if the engine fails, the noise will be magnified by the vents, making life more difficult.Because it is reliant on energy, it is unable to function during power outages or electrical failures.

  1. Let’s take a look at the advantages and disadvantages of power vent water heaters.


  • Power vent heaters allow the user to locate the water heater wherever in the home without having to worry about the natural venting of the exhaust gases
  • they are also more energy efficient.
  • Risk of dangerous gases spilling out of the vents and harming people has been decreased
  • It does not necessitate the use of a chimney, and the exhaust gases may be routed through PVC pipes.


  • When compared to a direct vent water heater, the installation costs are higher in the beginning.
  • Because of the existence of extra moving components, the cost of maintenance is higher.
  • It is reliant on energy and will not operate if there is a power failure.
  • Can push up the electricity cost
  • Because of the vent fan, it is possible to have noise issues.

What Is Better Direct Vent Water Heater or Power Vent Water Heater? The Verdict

  • We have discussed the differences between direct vent water heaters and power vent water heaters, as well as the pros and downsides of each type of water heater. Heaters that exhaust directly into the atmosphere are better suitable for older homes that have a chimney or other sufficient venting options. Keep in mind, however, that the location of water heaters in such systems is limited due to their size. Power vented systems are more adaptable and may be installed virtually anyplace in the home, independent of the presence or absence of chimneys or the presence or absence of vertical vents. However, because they require additional electrical power to operate, these power vented water heaters are not as efficient as direct vent systems. In addition, maintenance fees and power bills will rise as a result of this. There is also the risk that noise could detract from the environment of your property. In situations when you have a handy location for the water heater, as well as connections to vertical vents or a chimney, direct vent water heaters are a better choice. Aside from that, it may be employed in areas where power shortages are regular.
  • Water heaters with power vents are an option for families that live in a complex or who do not have enough room to locate the water heater near accessible vents. In addition, if you live in a region with fewer power outages, you can benefit from it since power vents lower the chance of poisoning.

The decision between a direct vent water heater and a power vent water heater is totally dependent on the user’s living situations and surrounding environment.When installing water heaters in your house, you should weigh the advantages and disadvantages of each system listed above in order to make an informed selection.Don’t miss out on: 11 Simple Techniques for Reducing Blender Background Noise What Causes a Microwave to Beep?

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.

  1. 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.
  2. Rushing this choice, on the other hand, would be a mistake.
  3. For starters, there are many various types of water heaters available, each of which has a particular energy-efficiency profile to choose from.
  4. 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.
  5. 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.
  6. 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.

  1. 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
