Scope of Use

The heat pump most suited to each situation is determined by a number of factors. When combining the heating for a underfloor heating and domestic hot water, sizing priority is given to the underfloor as it has the greatest load requirement. These factors include; floor area, insulation, building structure and climate. For more information about heat pump sizing please contact Hot Water Heat Pumps.
