Heating/ CALCULATOR

Heat-pump daily electricity

Convert useful heat from the heat pump and auxiliary heater into an ideal daily electricity estimate.

Useful heat from heat pumpkWh/dayThermal energy delivered by the heat pump during the day.

Average COP for the periodratioUse performance for the relevant temperatures and operating conditions.
