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.

Changes:

  • Fix data-entry error on Ebac 45C 4.63 to 4.38 (down to 4th)
  • 2024-02 Ovum AC208P from 5.78 to 5.53 @ 35C, 4.15 to 4.00 @ 55C etc. old-datasheet
  • 2024-02 EBac H1A05WG-GB from 5.11 to 4.91 @ 35C, 4.12 to 3.96 @ 55C old-datasheet
  • 2024-04-25 Added Aira 6KW 1.0 with SCOP figures from MCS Product Database
  • 2024-06-03 Added Octopus Cosy 6 with SCOP figures from MCS Product Database
  • 2024-06-10 Remove inconsistent standard in favour of 3rd party MCS correlation for SCOP accuracy, devices re-ordered respectively
