Quite an exciting milestone! The HeatpumpMonitor.org results are now available published in an academic paper 
thanks to Jan Rosenaw (University of Oxford) for working with us to make this possible!
The paper is available as open access in Elsevier Energy and Buildings here: https://www.sciencedirect.com/science/article/pii/S0378778825015154
-
The paper highlights the overall average performance result that systems on HeatpumpMonitor.org have achieved (SPF H4 of 3.86 for 169 air source systems, Nov 24 to Nov 25).
-
It covers the same discussion of weighted average temperatures that we have documented in the OpenEnergyMonitor documentation here: Low flow temperature = High performance — OpenEnergyMonitor 0.0.1 documentation
-
It also covers the analysis of the difference between the Electrification of Heat trial results and HeatpumpMonitor results documented here (including the simulation analysis): Analysis of Electrification of Heat trial data — OpenEnergyMonitor 0.0.1 documentation
Thanks to everyone who has contributed heat pump data to HeatpumpMonitor that has made this possible!
