How do you measure your COP? I'm having heat pumps installed now, and am interested in how everyone has this information at their fingertips.

  My heat pump will say how much kWh of heat it has output (~2400kWh last month). I also have a separate electrical meter just for the heat pump that tells me how much electricity it consumed (~700kWh last month). I simply divide the heat output by the electricity consumed which gives me a COP of ~3.4. I can connect the meter to the heat pump, in which case the pump will use pulses from the meter to calculate it internally, but i havent set that up. I have no idea why it doesnt come with an integrated meter... seems like that would be easier tbh.

    It's interesting. I wonder how they measure heat output.

      not sure, but i guess its sampling the flow through and the delta-T across the condenser and doing whatever the relevant calculation is off that.
