Description

The Duoheat range of dual-purpose heat pump water heaters eliminates the need to invest in two separate heat pumps. They are ideal for heating both underfloor and domestic hot water needs, reducing unit redundancies and minimising the overall footprint of the equipment.

The Duoheat system pipe work distributes heat to the entire floor area, so there are no hot or cold spots. Separate controls for each zone means users can tailor the water flow for each area to suit individual room or zone requirements night and day. 'Ub' series Duoheat Heat pump water heaters have been developed specifically for use in residential and commercial hydronic floor heating systems.

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.
