This is a comparison table of all 2024-2025 heat-pump datasheet figures for make+models I am aware of.

Criteria:

  • Target property 4-5Kw
  • EN 14511/14825 (?) Average Climate and Low temperature = 35C and Medium = 55C
  • Ordered by SCOP where higher is better. Where order is ambiguous the SCOP at 45C is used, and then 35C i.e. We prefer mild weather performance which gives greater yearly SCOP.

All SCOP figures are now correlated (i.e. replaced) with MCS 3rd party certified figures where possible. Please be aware :broken_heart: currently indicates a device that has not got a verified performance and may not be correctly ranked among others.

31.23 = SCOP at 45C calculated as MEAN(35,55) when not made available in datasheet. This produces conservative underestimate of SCOP when unavailable.

4Only if directly shown in datasheet, many, if not all could be wall mounted, but not directly mentioned in datasheet.

ToDo:
