I’ve posted another test result from my EcoDan from last night, it met the datasheet output of an average output of 5kW and COP of 3, though time between defrosts seemed quite long! not really conclusive enough yet, just another datapoint: 5kW R410a Ecodan PUHZ-W50VHA2(-BS) maximum output testing - #7 by TrystanLea
@glyn.hudson also did a test at the same time on his Samsung 5kW (in the same village so similar conditions) and also achieved the same match to datasheet capacity 4.5kW on his, full details in his thread here https://twitter.com/glynhudson/status/1729591159146586180
