Heat Pumps

Heat Pumps are energy efficient electric pool heaters, that work by transferring heat from the surrounding air into the pool water, rather than generating heat themselves. In terms of energy used to heat they typically are more efficient then a gas powered heater. These units require temperatures above 10 degrees Celsius to perform efficiently.
