new 2-3 year old houses, about 110-120 sqm, occupied homes, West Pomeranian, 7 kW Panasonic heat pump, electricity consumption for heating with underfloor central heating from about 1000 to about 1800 kWh per year. Of course, the controllers underestimate it a bit (percentage-wise maybe by e.g. 15-25%), but still these are low electricity costs used by the heat pump. For DHW purposes, consumption can vary and be 30% or 50% or 100% of what goes to central heating (depending on the amount of water used, preferences, water temp.).
