What is an atmospheric vent hot water heater?
Atmospheric gas water heaters vent their exhaust through a vertical or upward sloping metal duct vent to exit the home. The venting must be vertical or upward sloping so that the hot exhaust rises up through the venting to exit your home.
Are direct vent water heaters better?
Another benefit offered by a powervent water heater is lower energy consumption. They’re more efficient, so they use less fuel… but not a lot less. Because they don’t use a vent that runs up through the middle of the house, powervent water heaters give a lot more flexibility when it comes to locating the unit.
What is an atmospheric heater?
But an atmospheric furnace is simply a furnace that draws on air inside a home in order to mix with the natural gas from the burner and allow combustion to occur. A grill on the furnace pulls in this air for the combustion process. This, in turn, pulls air from the rest of the house.
Why are power vent water heaters more expensive?
A power vent water heater will cost more initially due to extra equipment needed such as the fan and blower. Also, you will need to run a power line to the fan which will also add to the cost.
Can you vent hot water heater out wall?
Venting. All natural gas water heaters must be vented to the outdoors to remove the byproducts of combustion. The vents go directly through an outside wall, and can also bring in combustion air to the gas burner.
Does an electric water heater need to be vented?
No. Unlike gas tankless water heaters and gas traditional tank style water heaters, electric tankless water heaters do not require any venting. This is often one of the deciding factors when choosing whether you should purchase a gas or electric tankless water heater.
What’s the difference between atmospheric vent and power vent water heaters?
Two of the most common type of water heaters are atmospheric vent water heaters and power vent water heaters. While atmospheric vent water heaters are simple and don’t require electric power or moving parts, power vent water heaters use a fan to push the excess gases through the venting pipes and outside.

What’s the difference between vented and open vented hot water systems?
Choosing between the two types of heating systems and cylinders depends on your budget and your type of home. Vented systems are known as ‘gravity fed hot water systems’. Vented cylinders (also called open-vented cylinders) need to be supplied by a large tank of cold water which is kept in the loft.
What do you need to know about venting a hot water heater?
Water Heater Venting Basics. All water heater venting systems use a vent duct or pipe—also called a chimney or flue—to bring exhaust gases from the water heater to the outdoors. The duct may be metal or plastic, depending on the type of vent system.
How does a direct vent water heater work?
The direct vent design solves two problems that are inherent in an atmospheric vent water heater: Water heater manufacturers use a gap between the top of the water heater flue and the vent connector pipe above it in a regular water heater to pull additional air into the upward flow of combustion air to help it exit more efficiently.

What are the disadvantages of a power vent hot water heater?
Noise is another disadvantage with a power vent, as there is a slight sound some homeowners notice when the blower or fan runs as the hot water heater is operating. For most people, the noise is not that noticeable or distracting, however it’s something you should be aware of should you consider this type of vent.
