Annoyingly I can’t view current day usage. But previous days have been 40-50kWh when it’s about 5c outside in the day.

forcast -4c later this week for 2 days which is below design temp so will be whacking the 7kw log burner on!

At 5-10C outside, we easily push 55-60kWh per day. When temperatures tumble to zero and below, we had days in Feb two winters ago where we did over 100kWh. On today's tariffs that's a killer.

Hi @editor

is that electrical consumption, or heat output?

@drew-pa, electricity consumption. In January 2021, which was one of our coldest winters, we consumed 2,231 kWh of electricity. More detailed info here: https://myhomefarm.co.uk/potential-air-source-heat-pump-running-cost-issue

Ours used to be like that until we de-zoned everything. Much better now

These are quite scary amounts of electricity consumption. Is this normal?

The amount of electrical energy used is dependent upon the overall heat loss and how efficient your system is operating, plus of course the none heat pump electrical energy used.
