A heat pump moves heat instead of making it, so it delivers several times more heating or cooling per watt than resistance heat.

FAQ
How many watts does a heat pump use?
Typically 1500-5000 watts while running, with a surge at compressor startup.
Why is a heat pump efficient?
It transfers existing heat rather than generating it, so each watt does more work.
