How to Compare Heat Pumps
Before reviewing individual brands, the key specifications that allow meaningful comparison between heat pump models are worth understanding.
SCOP (Seasonal Coefficient of Performance) is the efficiency rating for heating — the ratio of heat output to electrical energy input averaged across a full heating season. A SCOP of 4.0 means 4 units of heat are delivered for every unit of electricity consumed. Higher is better. Most current heat pumps achieve SCOP of 3.5 to 5.1.
SEER (Seasonal Energy Efficiency Ratio) is the equivalent rating for cooling mode. Relevant only for models with cooling capability.
Noise level in dB is critical for urban installations and properties with noise-sensitive neighbours. Below 50dB is generally considered quiet; below 45dB is exceptionally quiet.
Minimum operating temperature indicates how cold the outdoor air can be before the heat pump’s efficiency falls below the threshold for effective heating. Models with -25°C to -28°C rating maintain performance throughout UK winters including the coldest snap.
Output range in kW determines which property sizes the model suits. Domestic models typically range from 3.5kW to 16kW.
