Ground source heat pump systems, air source heat pump systems 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 water 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 water 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 for instance 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: many contemporary steel column and tubular radiators, have also been used with great success on heat pump systems."  

Also it is always recommended that you employ the services of a consultant heating engineer to design your heat pump system; the cost involved will be paid for in reduced operating costs in a short period of time. Heat pumps are great, but full system design is imperative if the full benefits are to be enjoyed.
