5 Things to Know About Pool Heater Maintenance

Clean the filter weekly during swimming season Restricted water flow from a dirty filter or blocked skimmer causes most gas and propane heater failures.

Flush the heat exchanger yearly with descaling solution Mineral scale builds up inside the heat exchanger, especially in hard water areas. Pull the drain plug and flush the line annually.

Keep electric heat pump air coils clean Leaves and debris piling up around the unit reduce efficiency. A quick rinse with a garden hose is enough.

Winterize properly in freezing climates Drain the pump, blow out the lines, and remove the heater’s drain plug. Standing water can crack the heat exchanger.

Skip expensive chemical treatments and professional service calls For a standard residential setup, a garden hose and a weekend of simple maintenance are all you need.
