Pool Heaters and Heat Pumps
Heat pumps, gas, electric and solar heaters compared on heating output and the pool sizes they're built for.
Heat pumps move heat from the air into the water and cost far less to run than gas, but their output falls as the air cools, so they suit holding a temperature through a warm season. Gas heaters heat quickly in any weather and suit occasional use. Solar heaters are cheapest to run and depend on sun.
Size by how fast you want to warm the water: BTU per hour = gallons x 8.34 x degrees of rise / hours. A solar cover cuts heat loss more than any heater upgrade.
