What is the Energy Factor rating?

This rating is used by the US Department of Energy to rate the energy conversion efficiency of water heaters. It is often abbreviated EF. The higher the number, the more efficient the water heater is. It is a useful metric for determining the future energy efficiency of your water heater, but must be viewed as a theoretical estimate, and your actual EF may vary according to the unique circumstances of your home.

What is Energy Star?

Energy Star is a voluntary program set up by the Environmental Protection Agency in 1992 that seeks to rate a wide range of residential and commercial equipment according to their energy efficiency in order to promote awareness about the risks of air pollution. In the water heater industry, there are minimum Energy Factor ratings that must be met in order to qualify for the Energy Star rating, such as greater than 0.62 for gas tank water heaters and greater than 0.82 for whole-home gas tankless water heaters.

How can I apply for a Federal Tax Credit?

Depending on the current status of the Taxpayer Relief Act, you may be eligible for Federal Consumer Tax Credits for Energy Efficiency. This applies to non-solar water heaters whose Energy Factor rating qualifies. You could receive a tax credit of 10% of the cost up to $500, or some other specific amount on your new water heater installation. You have to fill out the 5695 form with the IRS. Speak to one of our friendly technicians to find out whether your new water heater will qualify.

Does the water leaking out of the overflow pipe from the water heater indicate a problem? Is it dangerous?

Because your tank water heater contains pressure that can fluctuate and become too high, sometimes it is necessary to relieve that pressure. Your water heater is equipped with a pressure release valve with an overflow pipe that allows it to drain naturally when necessary. This isn’t typically an issue unless it seems as though the water leaking has become excessive, in which case you should have water heater inspected.

My water heater makes a rumbling sound—should I be concerned?

Yes, you should. While you can expect a certain amount of operational noise to emit from your water heater, a rumbling sound could indicate excessive sediment or scale buildup at the bottom of the tank that can cause the water temperature to reach scalding temperatures.
