Icopower Esco installs air source heat pumps to help clients save on energy used in heating of water. With ASHPs, savings of up to 60% are achievable. The pumps absorb renewable heat from the environment to heat water thereby replacing traditional hot water boilers; Electricity is used by the pump as it compresses the liquid to increase its temperature. It then condenses back into a liquid to release its stored heat. Less electrical energy is used in the process as compared to using the traditional boilers
