Most homeowners who have heat pumps use them to heat and cool their homes. But a heat pump also can be used to heat water -- either as stand-alone water heating system, or as combination water heating and space conditioning system.

Air source heat pumps are a great, energy efficient choice for heating your home and water and as well as being low maintenance, they can help to cut your heating costs and lower your carbon footprint.

Commercial heat pumps take natural thermal energy from the air, ground, or water and turn it into heat that can be used for hot water and heating systems. They are an alternative to the traditional gas boilers that are currently used to heat business properties up and down the country.
