Pool Heater
A heater raises and maintains pool water temperature. Gas heaters heat quickly on demand, heat pumps extract heat from the air efficiently over a slower ramp, and solar heaters route water through rooftop or ground panels that use direct sunlight.
Most manufacturers estimate this range for a well-maintained pool heater, though the real number depends heavily on usage, water balance, and how consistently it's serviced.
Routine maintenance
- Clear debris and vegetation from around a heat pump's air intake and exhaust
- Inspect solar panel connections and check for cracked tubing each season
- Have a gas heater's burner, venting, and gas pressure inspected annually by a licensed technician
- Check the heat exchanger for scale buildup, especially in pools with high calcium hardness
- Verify the thermostat and safety switches respond correctly at the start of each season
Common issues
- Ignition failure or recurring pilot/control-board faults in gas heaters
- Reduced heating output from a heat pump in very cold ambient air
- Scale buildup on the heat exchanger from imbalanced water chemistry
- Cracked or leaking solar panel tubing after a freeze cycle
When to replace
A heat exchanger with pinhole leaks, a control board that's already failed once, or an aging gas unit facing a repair bill approaching half its replacement cost are typical signals to replace rather than repair. Heat pumps and solar systems are generally worth repairing longer, since major failures are less common across their typically longer lifespan.

See pricing →An automation system centralizes control of pumps, heaters, lighting, and sometimes chemical feeders through a control panel or app, and can include ORP/pH controllers that automatically adjust sanitizer and acid dosing.
A pool cover reduces evaporation, heat loss, and debris, and — in the case of safety and automatic covers — restricts access to the water when it's not in use.
The pump circulates water from the pool through the filter and back again — the mechanical heart of the filtration system that every other piece of equipment depends on.
