At the holiday house (www.VarisHoliday.co.uk), we now have about three months data (96 days). The house has had guest in for most of this time but we ran the heating regardless as we wanted to bring the house which had sat with minimal heating through the winter up to proper warmth throughout.
From 5th May to 9th August:
Total house import 1066 kWh
PV Generation 1073 kWh
Air source heat pump consumption 1082 kWh
So on average, 11kWh a day for each measure.
We've experimented with the setting on the ASHP so that it runs more during the day so we maximise running the ASHP on sunshine.
