Ground, Air and Water Source heat pump systems require larger radiators than those used on conventional boiler heating systems. This is because heat pump systems operate at lower temperatures. Heat pumps operate between 40 and 50 degrees Celsius, whereas conventional boilers operate between 60 to 80 degrees Celsius. Radiators on a heat pump system, operating at these lower temperatures, will produce around 30% of the heat output of the equivalent radiators on a conventional system.
Dave Wood, of Feature Radiators, the UK’s leading radiator specialist, commented:
"In our experience, most heat pump design engineers favour aluminium radiators as being the "radiator of choice" for these type of installations. Aluminium radiators such as the Decoral, Trend, Lie Low and I-Line have a very low water content and the excellent heat conducting properties of aluminium gives these radiators a rapid reaction time: achieving full radiator temperature up to three times as fast as steel panel radiators. Aluminium radiators aren't the only radiators suitable: Our steel Bordo and Volcano radiators, both with excellent heat outputs, have also been used with great success on heat pump systems."
