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

How to spend less running a heat pump
- Cut the hours: A heat pump at 6 h/day runs about $91.80/month — trimming one hour saves roughly $15.30/month.
- Tune the setpoint: a degree or two changes how long the heat pump has to run.
- Upgrade efficiency: a newer heat pump near 1,500 W uses far less than an old 5,000 W one.
- Kill standby: a smart plug or timer removes the ~5 W it draws even when off.

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.
