75,000 to 112,000 BTU suits an in-ground pool of 15,000 to 25,000 gallons in a warm climate. They run on a 230 V circuit, typically 30 to 50 A, and need a steady flow from the pool pump. Size up in a cooler climate or for a pool without a cover: a bigger unit warms the pool faster in spring and holds temperature on cool nights.
