Heat Pump Water Heaters

It's generally easier to move something than to make something. Putting that principle to use, heat pump water heater (HPWH) technology uses electricity to move heat from one place to another instead of generating heat directly. This simple principle can save the average household almost $300 per year on its electric bills -- and reduce its carbon dioxide emissions significantly -- compared to a standard electric water heater.

The Stiebel Eltron Accelera® 300 features the highest energy factor (2.5) of any HPHW technology, reduces hot water costs by up to 80%, and comes with a 10-year warranty. The Accelera makes sense for all climates, and can be placed inside the house or in the garage. It is eligible for a federal tax credit of 30%, as are other ENERGY STAR qualified heat pump water heaters.

Savings and Benefits Big savings. ENERGY STAR qualified heat pump water heaters can save the average household almost $300 per year on its electric bills compared to a standard electric water heater. That's enough money to go on a weekend getaway every year. Larger families — that typically use more hot water — will save even more! A smart investment. While a qualified heat pump water heater costs more upfront, the savings will pay back the difference in about three years. Replace your aging electric water heater before it fails, and start enjoying the savings right away. A purchase that protects the environment. If everyone buying an electric water heater this year chose an ENERGY STAR qualified heat pump model instead of a standard model, we would avoid 19.6 billion pounds of carbon dioxide emissions. That's the equivalent of taking 1.6 million cars off the road.



How It Works

To understand the concept of heat pumps, imagine a refrigerator working in reverse. While a refrigerator removes heat from an enclosed box and expels that heat to the surrounding air, a HPWH takes the heat from surrounding air and transfers it to water in an enclosed tank.

A low-pressure liquid refrigerant is vaporized in the heat pump's evaporator and passed into the compressor. As the pressure of the refrigerant increases, so does its temperature. The heated refrigerant runs through a condenser coil within the storage tank, transferring heat to the water stored there. As the refrigerant delivers its heat to the water, it cools and condenses, and then passes through an expansion valve where the pressure is reduced and the cycle starts over.
