The power vent water heater has grown in popularity as homeowners gravitate toward more energy efficient devices. By using exhaust from the home's existing plumbing system, these heaters save energy and promote improved air quality and pressure within the home. Knowing what kind of heater you will require is the first step to purchasing this type of device.

The power vent water heater runs on combustion air provided from the home. The device requires an electrical connection, and running the fan costs on average a few dollars a year for a family of four. These devices often come with an automatic shut-off mechanism if the fan is disabled for some reason.

Energy Efficient

Power vent water heaters save energy by using outdoor air that already has been expelled and is already hot or cold. Using indoor air, by contrast is more energy-expensive. In addition, these heaters are more flexible in their placement, and some less expensive to install if they don't have to conform to fitting into a chimney. Power vent water heaters offer energy efficiency and air quality to its consumers.

The devices typically are sold in 40- to 50-gallon tanks and put out on average 40,000 to 65,000 BTU an hour. Not only do these devices meet Energy Star criteria, they often exceed it, ranking up to 15.5 percent more efficient than federal standards. Buyers of the power vent water heater can expect to save as much as 14 percent annually in energy costs.

To Chimney or Not to Chimney?

Whether you will need to use your chimney will determine what kind of power vent water heater you use; those with metallic b-vent material must be connected to a chimney, while those with small, plastic piping offer more options. When considering a power vent water heater, weigh the benefit of maintaining a chimney versus purchasing a device with a side vent. Also weigh the costs of these two methods, and when building a new home consider not installing a chimney to save money if you opt for a heater that does not require one.

Whether or not you have a chimney, consider how a power vent water heater can improve your life. Not only will you save money in energy cost, you will have cleaner air and your home will function more smoothly because of improved indoor air pressure.
