How to Install a Power-Vented Water Heater

It’s simpler to run the vent if you introduce a “control vented” sort of flammable gas (or propane) water radiator. This sort of venting framework is not quite the same as what you see on most gas water radiators. Most have a “natural-draft” type of vent, where the hot waste gases rise through an open draft diverter and into metal pipes,which eventually lead to the outdoors. Running one of these vents is complicated and may be expensive. It’s best left to a professional.


Power vents streamline a gas heated water storage establishment

The primary advantage of a power vent is that the water heater can be located in any area. Most importantly it does not require a vertical vent or chimney. It could be that the location where you want to install your hot water heater is not near the chimney, or your home does not have a chimney. Either way, a power vent can be vented by simply running inexpensive pipe horizontally.

However, the drawback to this type of water heater total cost consideration.  The blower/fan portion of the vent requires electricity to operate, the cost of the actual blower or fan, and running a power line to the fan. Essentially, because the power vent requires a fan/blower to operate, the costs of heating water will be higher over the power vent’s life span.

Diminish high electric bills by supplanting an electric water radiator with a petroleum gas or propane warmer. At that point lessen establishment costs by introducing a power-vented model with effectively vented out a sidewall.

Power-vented water warmers work equivalent to conventional water radiators; however, the fumes gases smothered with a little fan as opposed to rising upwards through metal channels.

Power-vented water warmers cost more than regular draft radiators, yet on the off chance that you don’t have a current smokestack, the establishment will be less.

You ought to be acquainted with pipes, gas channelling, and wiring, and may need the venture examined.

Converting atmospheric vent to direct or Power Vent

There are three kinds of water radiators you can look over: control vent, direct vent, and power direct vent. Every type has its own pros and cons.

The power vent water radiators use the electric fan to evacuate the results of burning out, and these models draw the air from within the house. Keep in mind that these heaters cannot be connected to the chimney and share venting with other appliances due to the negative pressure that affects the performance. Its prescribed sort in the event that you need to run a long pipe and need adaptability in the establishment

Direct venting is suggested for homes in the event that you would prefer not to be power reliant as these units evacuate the pipe gases utilizing the distinction in weight between the hot pipe air and outside colder air.

Furthermore, you don’t need to stress over conceivable spill as these units utilize the outside air for ignition and have the fixed burning chamber and pipes. Likewise, these models make no commotion since there are no versatile parts, they require significantly less upkeep so fewer things to turn out badly and stress you.

About the DV Heaters

With the DV heaters, chances of the house going under negative pressure are minimal. The pipe inside the pipe type allows you to have the vent termination at one point. The negative is the limitation on distances.

Power Direct vent is used when indoor air quality is a concern. It draws the fresh air from outside for combustion while removing the exhaust gases with the use of the fan.

Regarding your concern about the closeness to the windows and another opening… there are codes that oversee where a vent for certain water heater can be located, meaning how far from the door, window, deck, exhaust for the furnace and so on.

Your plumber should follow the local building codes and gas codes that are related to this problem. You can also consult the manual for your particular unit.

Keep in mind that improper venting might lead to carbon monoxide poisoning (it is odourless).

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

You can likely use a direct vent, but the exhaust will have to be completely changed. The termination outside may or may not have to be moved, depending on decks, windows, or doors.

should be no problem at all. some work on the cement blocks should be all you need to do.

the pipe is much larger since it is a pipe inside a pipe. it takes fresh air from outside thru the space around the exhaust.

Power vent water heater vs Direct vent

  • When utilizing an immediate vent water warmer, water is warmed by the warmth of fuel ignition. An immediate vent framework normally results in lower water warming expenses, in light of the fact. The fumes gases vented vertically, with no additional power required similar to the case with the power vent water radiator.


  • A power vent water heater uses a blower or fan to exhaust gases by pushing them through vent pipes that are horizontal. In some situations, this may be the only type of water heater that makes sense, because a chimney or vertical vent is not necessary. Some locations don’t have access to a chimney or vertical vent, so your options are limited.


  • The differences between a power vent and direct vent hot water heater, and it’s obvious a power vent will result in higher cost – but sometimes it simply cannot be avoided. When you don’t have access to a vertical vent or chimney, a power vent may be the right solution for you.

Direct vent water heater

  • When using a direct vent water heater, water heated by the heat of fuel combustion. A direct vent system typically results in lower water heating costs. Because the exhaust gases vented vertically, with no extra power required as is the case with the power vent water heater.

Rheem power vent water heater

  • The Rheem Power Vent is a vitality effective gas water warmer with productivity of .67 EF. The Power Vent comes in 40 and 50 gallon tall and short limits. 40-gallon models have a First Hour Rating (FHR) of up to 71 gallons, while 50-gallon models have an FHR of up to 87 gallons. The Power Vent includes a coordinated self-indicative framework for simple establishment and upkeep.


  • The unit includes a metal channel valve and a T&P valve, and a licensed magnesium anode pole shields the tank from rust and consumption. The Guardian System includes an air/fuel shut-off gadget which kills the warmer if combustible vapor amasses. The Power Vent offers venting keeps running of up to 100 feet with PVC, ABS, or CPVC pipe choices.


Usually, the warranty for the Rheem Power Vent water heater comprised of the following:

  • 6-year limited tank warranty
  • 6-year limited parts warranty

The limited warranty does not cover labor expenses.

Can a standard water heater be side-vented?

A certain amount of feet rises to draw the gasses up and out before offsetting to a certain degree.

You can buy a side wall vent kit made by Tjernlund but that might cost as much as a power vent water heater.

If your water heater is near an outside wall you can go with a direct vent water heater. They are a bit more expensive but do not require electricity to run a power vent

Water heater vent types

All water heaters that burn natural gas or propane require a venting system. The process of burning of the gas called combustion and it creates heat, exhaust gases (including highly poisonous carbon monoxide), and moisture. The water heater’s ventilation system removes these by-products from the home, making it a critical safety feature. In most cases, the type of ventilation system depends on the type of water heater.

Water Heater Venting Basics

All water warmer venting frameworks utilize a vent pipe or pipe—likewise called a fireplace or pipe—to bring exhaust gases from the water radiator to the outside. The channel might be metal or plastic, contingent upon the sort of vent framework.

Water radiator conduits may lead legitimately outside, or they may integrate with a bigger vent pipe that additionally serves a gas or propane heater or evaporator in the home. Much of the time, the fumes from the bigger apparatus warms up the regular vent, improving the progression of the water warmer vent.

Notwithstanding venting, gas and propane water radiators need an air supply for ignition. This may originate from the environmental air in the house, or it can get through a vent pipe that pulls air from the outside.

Proper Venting Prevents Back drafting

The most widely recognized issue related with water warmer venting a condition called back drafting. The exhaust from the water radiator neglects to leave the home through the vent and rather winds up in the house. Back drafting can have numerous causes, yet it is most usually because of poor vent structure or establishment or potentially a lopsidedness of air volume in the home.

The last is regularly a consequence of ventilation fans, for example, restroom or kitchen vent fans, that haul let some circulation into of the house and make a vacuum impact that draws exhaust descending and into the home from the water radiator vent.

Some water warmer venting frameworks evacuate the likelihood of back drafting with fan-helped ventilation or direct venting innovation.

Atmospheric Venting

Standard water warmers—the most widely recognized sort—utilize air venting. The vent comprises a vertical or upward-inclining vent channel that normally integrates with a typical vent. The framework works exclusively through common convection—in light of the rule that sight-seeing rises. Hot fumes from the water warmer normally ascend through the vent and into the air outside, making a draw that advances this upward wind stream. The intensity of the draw increments as the vent pipe warms up.

Climatic vent frameworks function admirably (and without power) in the event. The appropriately structured, and the home does not have fiery surge issues. Inadequately structured vents regularly have a deficient draw as well as are exceptionally defenseless to back drafting.

Power Venting

Water warmers with power venting accompany an electric blower fan (frequently calm) introduced over the water radiator and can have either vertical or flat vent channels. It depend on the lightness of sight-seeing it can run on a level plane to the outside of the house.

The blower cools the air so the vent can kept running in PVC pipe (as opposed to metal, required with climatic venting) and is anything but difficult to collect. The water warmer must have an adjacent electrical outlet for controlling the fan

Direct-Vent Water Heater

With an immediate vent framework, air for ignition drawn from a vent pipe that goes through an outside divider or the rooftop. Fumes gasses vented outside through a different vent conduit or through a different assembly of a similar pipe (this requires a twofold divider vent channel).

Direct-vent frameworks basically “inhale” outside air, so not exposed to the impacts of back drafting in the home. They additionally decrease the danger of inadvertent flames brought about by combustible vapors around the water warmer.

Water Heaters for Mobile Homes

Water warmers in trailers are like those utilized in standard homes, yet they should be intended for this application. Makers regularly won’t warrant water warmer in the event that it is introduced in a manufactured home and isn’t explicitly endorsed for that utilization.

Standard climatic water warmers in manufactured homes frequently require an outside access board. On the off chance that a water warmer situated within a manufactured house without outside access, it is no doubt a fixed ignition unit with direct venting.
