An interesting statistic on my daily readout is that the max kwh produced by my heat pump was 2.65 kwh. Remembering the temp last night was -7*C and the max my 11kw heat pump had to produce was 2.65 kWh. My own heat loss calcs showed I needed a pump of 9kw but my installer insisted I needed at least 11 kw.
