How do I know if my water heater is direct vent?
The difference is that a power vent water heater pulls in combustion air from the space around the appliance, then uses a fan to propel the exhaust through the vent. A direct vent system pulls in air from outside and then vents the exhaust through a horizontal pipe.
Why are direct vent water heaters so expensive?
Direct venting systems work well whether there is electricity or not. Power vent water heaters have more moving parts, which makes them more complex and costlier to install.
Does a gas water heater need to be vented through the roof?
In the US, it's required by code to have an exhaust vent, or flue, connected to the top of the water heater. That flue has to take the exhaust gases up and out of the house. This type of water heater is called a “natural draft” water heater because it removes the exhaust gases without assistance by a fan.

Can I replace a direct vent with a power vent?
A direct vent system pulls in air from outside and then vents the exhaust through a horizontal pipe. This difference in operation means that you can install a direct vent system almost anywhere, but a power vented water heater must be placed in a room with adequate airflow.
What is the difference between power vent and atmospheric vent?
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.
How does a damper work?
Fan blower devices and air currents above the chimney generate drafts within the main unit's heat exchange compartment. The damper component works in conjunction with furnace sensors to regulate draft levels. Normal air flows send harmful combustion gases up through the chimney flue, while directing heated air to water heater units. In effect, a system damper allows the furnace to operate at optimal energy efficiency levels.
How does a baseboard water heater work?
A baseboard water heater system operates off a hot water boiler unit. Using circulator pumps, hot water moves through heating circuits contained inside baseboard units throughout a home. These systems generate convection heat that travels through the air and radiant heat that's absorbed by objects and surfaces within a room. The radiant heat feature resembles the type of heat generated by ultra-violet rays from sunlight. This type of heat has a lasting warming effect, compared to convection heat, which uses air molecules to circulate heat in a room.
What gases are released when a water heater is leaking?
These gases largely consist of water vapor and carbon dioxide. The vapor becomes acidic and needs to be released in order to relieve combustion pressure and prevent the water heater from exploding. Power vent systems are an excellent option for protecting the integrity of your water heater unit.
