Energy is specified in KWh here, i.e. we have a metering system installed which states that our heat pump delivered 128024 KWh of heat and the electricity company's metering system tells me that it used 34844 KWh of electrical energy to do this.

Anyway, for one unit input we got about 3.6 units of output, which has been produced with an almost zero carbon footprint, as we buy only ecologically produced electricity.

And yes, English is a second language.

How does a meter compute delivered heat? Computing delivered electricity is easy, but to compute heat delivered you'd need to have adiabatic walls surrounding your house or something like that.
