We have recently bought newly built 2 story house (140m2) with the heat pump and foor heating completely insulated. Our electricity consumption is 600 KWh per month including heating end everything else. We keep thermostat at 20 degrees centigrade. Is the consumption too high or normal for the house of this size and configuration?

That sounds about right if you've got the thermostat at 20 degrees constantly; I live in a 700~ sq ft apartment and consume around 300kwh/pm; 10% of that is an inefficient NAS I built from old parts and I hardly use the heaters because god almighty are electric heaters inefficient.

Assuming you are in western Europe, I'd say for 140m2 it seems a bit more than okay, depending on how much windows you have. And depending how north you are. And depending on your usage (WFH, cooking...), it can be great.

I do have 9 windows, living room is the sliding one which is 2,5x4 meters. I rarely work from home, cooking almost every evening.

Depends on the outside temp too. Best to monitor SCOP. My 180 m2 house with 18 degrees inside in January w ground souce heat pump (IVT Geo 508) and normal radiators ->

- SCOP: 3.88

- kWh used: 525 kWh

- kWh produced: 2034.8 kWh

- Outside min: -11.4

- …max: 5.65

- …mean: 0.3

Nearly €120 a month for electricity sounds like quite a lot, but I don't know what's common for standalone houses.
