Radiator Outputs Could Cause Heat Pump Problems

April 12, 2024 10:00 - 51 minutes - 35.1 MB

Heat pumps move energy from and energy source e.g. air, ground water (hence they are called :air source, ground source) to a sink. The sink is the emitter system within a home e.g. radiators, underfloor heating (UFH) and fan coils. Engineers, Installers, designers and the occupants of a home rely on radiators having accurate power output data. Unfortuanlty, it looks like their is a big problem in the radiator industry: the published power outputs are being over stated. This has huge cons...
