A big factor for the total energy consumption besides the heatpump is the rest of the heating system.
For our house the yearly energy consumption of the heatpump is around 1.4MWh/y (for floor heating, warm water and cooling of the bedrooms in summer;this number is reported by the heatpump control system) but the hole heating system including all the pumps and so on is 2,55MWh/y.
