Is the water a little chilly? Fire up the heater! Heaters are part of most swimming pool equipment pads. Water at the normal temperature enters the unit and is heated by flames fueled by propane or natural gas. Warmer water exits the unit and enters the swimming pool.

Most heaters operate with a pilot or electronic ignition.

Pilot lights are lit continuously and may require re-lighting from time to time. Lighting the pilot is similar to a hot water heater. Just open the door on the front of the heater. Turn the gas valve to the pilot position. Push down the knob and the igniter button. Hold the gas valve down for a few seconds to make sure it stays lit.

Electronic ignition heaters use electricity to start the heater and contain no pilot. When you turn the heater on, a spark lights the heater.

Proper water balance helps extend the life of your heater. Corrosive water will cause problems for the copper heat exchanger. Make sure your water is always balanced!
