A power vent water heater is vented horizontally and vents exhaust through a horizontal pipe that leads out your home. An added fan/blower pushes the exhaust gases through this pipe. Extra power is required to power the blower, and this power source is separate from powering your water heater.
Does an electric water heater require a vent?
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.
Do electric water heaters have a flue?
Electric water heaters do not have a Flue Baffle. … The Flue Baffle is typically located inside of the heater, directly beneath the vent hood (Standard Atmospheric) or the blower/fan assembly, and it runs directly down the center of the heater. You cannot see the Flue Baffle from the outside of the unit.
What happens if a water heater is not vented properly?
The residual gas fumes from your water heater’s burn process must be drawn through the vent pipes and up the chimney to exhaust outdoors. When that isn’t happening properly, the results could be costly — or worse, extremely dangerous.
How does a direct vent water heater work?
A direct vent water heater uses special coaxial venting that has separate chambers for intake air and exhaust in a single assembled vent piece. The venting runs from the water heater through the side of your home. They pull and push air from outside to negate any backdrafting within your home.
Why are power vent water heaters so 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 a hot water heater out the side of the house?
Since flue gases from the water heater are warmer than the surrounding air, they will rise naturally through a vertical vent pipe or chimney to the outdoors. … This type of venting allows gas water heaters to be installed as far as 40 feet away from an outside wall and in homes without existing vertical vents.
What’s the difference between power vent and power 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 have a power vent water heater?
Venting systems are necessary to prevent flue gases from accumulating in your water heater. 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.
Are power vent water heaters better?
Power vent water heaters are more energy efficient, so they require less gas to operate. The lower energy consumption will save you some money, but probably not more than $20 a year, making this an added benefit, but not a deciding factor. … A power vent water heater can be a good option for this situation.
How hot does water heater vent pipe get?
If a water heater is set to store water at 140 F to minimize Legionella bacteria growth, the flue gas temperature will be about 160 F when the heater is new. As scale builds up and the heater efficiency falls off, the flue gas temperatures can easily increase to over 350 degrees F.
How high does a water heater vent need to be?
For a single-wall pipe, you need 6″ clearance, and you cannot pass it through a ceiling, floor, or wall unless it’s masonry or concrete (non-combustible). For the draft hood connection, you need to allow for at least 12″ of vertical vent before throwing an elbow fitting in the line.
