It is exactly as efficient as a resistive electric heater, but heat pumps are 3-4x as efficient.

- kloch 4y agoHeat pumps only work at that level of efficiency above about 10 degrees C. That is why they often have integrated electric resistance heaters.
- ericpauley 4y agoThis is an antiquated figure. Modern heat pumps maintain competitive performance at much lower temperatures.
- ericd 4y agoNot true anymore. Check out eg the Mitsubishi Hyper-Heat, if I’m reading the COP right, it’s something like 280% efficient at -8 C.
- AustinDev 4y agoIf I wasn't renting I would install a heat pump but, we don't have that option at the moment. I do throttle it back to 60F ambient temp in the evening when no one is there. I use a raspi with a temp sensor to control the speed of the hashing in the cluster.
