Typically Homeowners who have a Heat Pump use them to Heat or Cool their home. However a Heat Pump can also be used to heat a water heater.
Unlike the Conventional Water Heaters Heat Pump Water Heaters use only one source to heat the water. They use electricity which moves the heat from one place to another instead of in one place. This alone makes them up to three times more efficient then your conventional water heater system.
Heat Pump Water Heaters require insulation that will maintain the temperature between 40 and 90 degrees F year round. They will not operate efficiently if the space is cold, so it is recommended that they are installed in a warm space.
There are different options which make the Heat Pump Water Heater a wise choice, such as installing an air-source heat pump system. The air-source heat pump system combines the heating, cooling, and water-heating in one. This option allows heat to be pulled indoors from the outside in the winter, and from the indoor air in the summer time.
This type of system is recommended for warm climates, since they are more efficient in this type of climate.
