What is the fan on top of my water heater?
A. O. Smith power vent gas water heaters are equipped with an electric blower fan that is installed on top of the water heater, which requires an electrical outlet to be close to the water heater. The blower pushes the exhaust and excess heat through the exhaust venting.
What is the difference between power vent and power direct vent water heater?
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 do some water heaters have a power vent?
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.
What is the difference between direct vent and atmospheric vent?
Basically, the difference between the two is that the power vent water heater removes combustion gases from the atmosphere via a powered venting fan, while a direct vent water heater vents these gases into the outdoor atmosphere using a chimney or exhaust pipe.
Can I use old power vent on new water heater?
No. You cannot use a regular vented gas water heater in place of a power-vent water heater with PVC exhaust system. The gas valve/thermostat is not designed on the regular models to accept any changes. It depends on why the power vent unit was installed in the first place.
Can you vent hot water heater out wall?
Direct vent or horizontally vented water heaters are designed for installation where vertical chimneys or flues are not available or would be more expensive to install. The vents go directly through an outside wall, and can also bring in combustion air to the gas burner.
Can a power vent be added to a water heater?
Natural gas or propane hot water heaters are generally less expensive to operate than electric heaters, but installing a standard vent in a house without an existing chimney is expensive. It’s easier to run the vent if you install a “power-vented” type of natural gas (or propane) water heater.
Can a water heater be vented out a sidewall?
There are three types of venting and only a power vent is allowed to terminate at a sidewall. venting system (vent piping) and chimney by natural means. flame retention burners). a structure to the outside atmosphere in lieu of a chimney.
Can a direct vent water heater be vented horizontally?
Compared to atmospheric, direct-vent water heaters offer more installation flexibility because they can vent horizontally. They also operate more quietly than their power-venting counterparts.
How long does a power vent water heater last?
about eight to 12 years
Based on the manufacturer’s suggested service life, the life expectancy of a water heater is about eight to 12 years. That varies with the location and design of the unit, quality of installation, maintenance schedule and water quality.
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.
What happens if a water heater vent is not installed properly?
If a vent connector isn’t properly installed, the potential for the water heater to backdraft increases. One of the most common installation defects with a vent connector is improper pitch; the vent connector need to pitch upwards towards the vent with a minimum slope of 1/4″ per foot, and there should be no sags or dips.
How do you fix a drafty water heater vent?
One way to fix this is to re-arrange the common vent so the water heater vent connector is offset from the furnace. Here’s a common scenario for water heater draft problems: an old 80\% efficient furnace is replaced with a new, high efficiency furnace that vents through the side of the house, leaving the water heater vent an orphan.
How do you fix a hot water heater that won’t heat up?
Start by checking the circuit breaker to see if it has been tripped. If it has, it’s an easy fix – simply turn it off and turn it back on again. You may also have to replace the fuse if it has blown. The next step is to check the high-temperature cut-off. Open the panel and press the red “reset” button. Check to see if the water will now heat.
Do electric water heaters need to be turned off?
Electric water heaters are high-voltage appliances, which means you should take full precautions when working with one. Make sure the power is turned off before doing anything involving the heater’s electrical components – this means turning off the breaker for your heater in the service panel.
