Most homeowners who have heat pumps use them to heat and cool their homes. But heat pumps can also be used to heat water - as a stand-alone water heating system or as a combination of a water heating and space conditioning system.
Heat pump water heaters use electricity to transfer heat from one place to another, rather than producing it directly. As a result, they are two to three times more energy-efficient than conventional resistance water heaters. To transfer heat, a heat pump works in reverse like a refrigerator.
Whereas a fridge draws heat from the inside of the box and vents it into the surrounding room, a stand-alone air-source heat pump water heater draws heat from the surrounding air and vents it at a higher temperature into the tank to heat the water. You can purchase a stand-alone heat pump water heating system as an integrated unit with a built-in storage tank and a backup resistance heating element. You can also retrofit a heat pump to work with an existing conventional storage water heater.
The heat pump water heater needs to be installed in a location that maintains a year-round temperature range of 40º-90ºF (4.4º-32.2ºC) and provides a minimum of 1,000 cubic feet (28.3 cubic meters) of air space around the water heater. Cooler exhaust air can be vented indoors or outdoors. Install them in spaces with excessive heat, such as furnace rooms. Heat pump water heaters do not operate effectively in cold spaces. They tend to cool the space they are in.
Heat Pump Water Heater
Heat pump water heater systems usually have a higher initial cost than traditional storage water heaters. However, they have lower operating costs, which can offset their higher purchase and installation prices.
The following points also need to be considered before purchasing a heat pump water heating system.
Size and first hour rating
Fuel type and availability
Energy efficiency (energy factor)
Total cost of ownership
Proper installation and maintenance of your heat pump water heating system will optimize its energy efficiency. Proper installation depends on a number of factors. These factors include fuel type, climate, local building code requirements, and safety issues. Therefore, it is best to have your heat pump installed by a qualified plumbing and heating contractor (or geothermal heat pump system installer/designer).
When selecting a qualified professional, do the following.
request a cost estimate in writing
request a reference
check with your local Better Business Bureau for the company
see if the company will obtain a local license if necessary and find out about local building codes
Regular maintenance of your water heater can significantly extend the life of your water heater and minimize efficiency losses. Read your owner's manual for specific maintenance advice.
After installing and maintaining your water heater correctly, try some additional energy-saving strategies to help reduce your water heating costs. Some energy-saving devices and systems are more cost-effective when installed in conjunction with a water heater.
