As far as gas water heaters go, there are two popular venting options: direct vent water heaters and power vent water heaters. Depending upon which kind of system one uses will rely on the direction the vent is installed from the water heater to the outside so the harmful gases produced from the water heater’s burner are not released inside the home, but rather sent out into the outdoors atmosphere. You might have heard the term atmospheric water heater while looking at different types of water heaters. Likewise, air should be sent into the water heater for combustion to occur.

This video gives some tasks to perform to help see if your water heater is currently properly vented:

Direct Vent Water Heaters
It is optimal if the air required for combustion is from outside the house in order to decrease the danger of fires from the flammable vapors of the water heater. The air from outside the home will either be vented through a wall or the roof of the house. Direct vent systems will help resolve the concern of not having enough indoor ventilation by drawing in air from outside the residence.

The basic concepts of a direct vent water heater is that the heat produced from the burning of fuel is used to heat up the water in the storage tank. The exhaust gases are then vented outside the home. Given that warm air is lighter than cool air, the exhaust gases will normally rise and head out with the venting system. The ideal scenario is to have the vent pipes be installed to go vertically out from the water heater, without any requirement of any kind of blower to help push the gases out. One still has to beware about backdrafting, which is when the exhaust fumes enter back into the home instead of escaping through the vent to the outside. Likewise, conventional atmospherically-vented water heaters are not as energy efficient as other more current kinds that do not permit as much of the warm air produced to leave up and out the vent pipes.

Within the category of direct vent water heaters there are various types we will not discuss now, that can have different types of types of venting choices, like having a single or dual vent channel. However, there are times when a blower is required to aid with the removal of the gases, which leads this conversation to power vent water heaters.

The following video explains in more detail the details of a direct vent system:

Power Vent Water Heaters
As can be presumed from above, power vent water heaters have a fan or blower connected to assist with the removal of exhaust gases from the hot water heater. There are times that a water heater can not be installed where it is simple to set up a vertical vent or chimney. Given that a fan is utilized for eliminating the exhaust gases, the vent pipes can be installed either horizontally or vertically, or a mix of both.

The major advantage then for power venting is that ones water heater can be installed practically anywhere in the home. Another benefit is that generally PVC pipes can be utilized for the ventilation due to the fact that the blower will cool the exhaust air enough that it will not be too hot for the PVC pipe to manage.

Some downsides with a power vent system is that it could cost some to initially set up if the existing ventilation system is not in place. And, the equipment cost of the blower (though not that costly) and if one has to install a power outlet within six feet of the water heater’s position. It will make use of some electric power to run the fan but that also is not a big expense. Lastly, the blowers, depending upon the kind, run relatively silently, but some property owners do not like the added ambient sound it makes. With the appropriate installation Water Heater Repair Nashville can help reduce the noise of the blower within the home.

In conclusion, there are a fair amount of differences between direct and power vented water heaters.
