How Much Does It Cost to Run a Pool Heat Pump?
A pool heat pump moves heat from the air into thousands of gallons of water — efficient per BTU, but the sheer volume makes it a major seasonal load. At the US-average rate of 16.5¢/kWh, running a pool heat pump costs about $100.25/month ($1,203.04/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.

Cost = power (kW) × hours × days × your rate. Defaults are typical values — enter your appliance's actual watts (often on a label) and your real rate for a precise figure.
How much electricity does a pool heat pump use?
At 5,000 W for 4 hours a day, a pool heat pump uses about 20 kWh per day — roughly 608 kWh per month and 7,300 kWh per year. That's about 70% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what a pool heat pump really costs you
The estimate above uses typical wattage and hours. This load is usually hardwired or on a 240 V circuit, so a plug-in meter won't fit it; a whole-home monitor's sensors clip onto the circuit's wires inside the panel and log its real kilowatt-hours. That means working in a live panel — hire an electrician if that isn't you.
