What size radiator do I need for a heat pump?

The size of radiator needed for a heat pump will all depend on the room you are heating. You can start by calculating the BTU requirements for your space, and then apply the manufacturer’s correction factor for your chosen heat pump. This will give you a new BTU requirement, and you can shop our range of beautiful cast iron radiators. To maximise the size of the radiator without sacrificing too much space, we recommend placing three radiators in a bay window. You can also opt for statement 9-column radiators, or choose a larger ornate design like the Balmoral.
