Need to Know
- Energy bill savings will offset the investment cost within 5 years
- Need to consider the amount of space available for the installation
A hot water heat pump uses electricity to transfer heat from the air or ground to heat water. It works like a refrigerator or air conditioner, but instead of cooling air, it heats water. Hot water heat pumps use much less energy than a standard electric water heating system. In five years, the investment will pay off through reduced running costs. They are most efficient when the weather is warm but can still work well, even during colder months.
Hot water heat pumps can come as a split or integrated system. In a split system, the hot water tank sits inside the house and the compressor stays outside. In an integrated system, the compressor sits in the water storage tank. This option saves space but requires the installation to be outside. It is important to consider how much outdoor space is available to choose the best option.
