For a full year I have lived in a house that has one of these.

It’s a hot summer and I’m delighted that it can not only heat but also keep my place cool!

Now I got an email from my electricity provider that during the last weeks (I was at home most of the time) my electricity consumption was roughly twice of what it usually is.

Hence my question: compared to its heating capabilities, does a heat pump use much more electricity for cooling?

I’m not looking for a scientific breakdown.

edit:

Thanks for all replies so far. Cooling seems to be trickier than heating and I should keep my windows closed, which just feels wrong during summer… but apart from that cooling does not use more energy than heating.

    Why would they use more energy in one direction versus another? This doesn’t really make sense to me. Heating and cooling is just swapping which element is the condenser and which element is the evaporator.

    The gradient determines that. Moving heat energy from inside ambient 25°C to outside ambient 30°C is easier than moving heat energy from outside ambient 5°C to inside ambient 20°C, for example.
