Can the heat pump heat the whole house?
A. Yes it can. Newly built or well-insulated buildings can be easily heated with a heat pump. Old, badly insulated buildings can however be a problem in cold weather, with heat pumps struggling to satisfy them. In these buildings, the temperature of the radiators or underfloor heating may have to exceed the efficient working temperature levels for the heat pump. Fires or boilers are often necessary to ensure adequate heating in the winter. Even in very well insulated houses, it is not uncommon to retain a fire or stove for extra comfort in cold weather. Air source systems require more back-up heat then ground source systems.
