Heat Pump Water Heaters
Up until recently there were only two types of electrical water appliances commonly found in homes – hot water heaters and tankless water heaters. Now there is a new hybrid hot water heater, the electric heat pump water heater. Installing a heat pump water heater can reduce the amount of electricity used to heat water by 62% a year.
How a Heat Pump Water Heater Works
Heat pump water heaters work by removing heat they find in the air surrounding the water heater and transferring it to the water that’s in the hot water tank. The heat pump does this using a compressor. The heat pump’s evaporator vaporizes a liquid refrigerant under low pressure which then passes into the compressor. The compressor raises the temperature of the refrigerant which then passes into a series of condenser coils inside the water tank. The water draws the heat out of the coils, the refrigerant passes out of the tank through an expansion valve. This drops the pressure and the cycle repeats itself all over again.
Energy Savings from Heat Pump Water Heaters
This is cutting edge technology. The first models weren’t available until late 2009, but there are a number of reasons why home owners should already begin planning to purchase a heat pump water heater. A standard household with 2.6 occupants spends over $500/year just heating water with a standard electric water appliance. An ENERGY STAR qualified heat pump could cut that bill almost $300.00. So even though an electric heat pump water heater is going to cost more upfront, it will take only three years to recover the extra expense in electric bill savings.
Heat Pump Water Heaters Protect the Environment
Many people don’t realize that the electricity they use is actually very hard on the environment. In many areas electricity is generated by coal burning plants or diesel plants. When this is the case, heat pumps reduce the carbon dioxide footprint significantly. The U.S. Environmental Protection Agency calculates that if every electric water heater bought into 2010 had been replaced by an electric heat pump water heater, 19.6 billion pounds of carbon dioxide emissions would be eliminated in 2010. That’s like taking 1.6 million cars off the road.
Hybrid Hot Water Heater
There are advantages to a hybrid system that combines traditional electric heating elements with condenser coils from the heat pump. These hybrid models can be set to heat water entirely using the heat pump, which is great if you don’t have a family that places heavy demands on the hot water tank. Yet, the tank can be set to hybrid mode, which defaults to heat pump only unless the demand rises. For times when you have extra high demand, such as when you have guests, a hybrid electric water appliance can be set to cycle the heating elements on more often to keep up with the higher demand.
When temperatures drop too low for efficient heat pump operation, a hybrid electric heat pump water heater can also be set to standard mode. That way the compressor doesn’t continue to work when the temperatures drop below 45°F.
