By heat pump type
Typical capacity is the middle half of each group; medians cover every product of that type.

|---|---|---|---|---|---|---|
| Air Source (ASHP) | 2,874 | 10.42–91.2 kW | 4.49 | 64 dB(A) | 170°C | 865 |
| Ground Source (GSHP) | 354 | 9–30.9 kW | 4.98 | 47 dB(A) | 82°C | 140 |
| Water Source (WSHP) | 1,087 | 92.7–568 kW | 5.7 | 86 dB(A) | 170°C | 7 |

Comparing fairly
| SCOP, not COP | Use SCOP at the same flow temperature (W35 vs W35). More |
|---|---|
| Test conditions | Only compare figures measured at the same condition, e.g. A7/W35. |
| Noise | Compare sound power with sound power, not sound pressure. |
| Capacity | Check output at your design outdoor temperature. Size calculator |
| Grants | Only MCS-certified products qualify for the Boiler Upgrade Scheme. Funding guide |
