If a natural gas heater isn’t an option because you don’t have a natural gas line in your home, or you do but you can’t install a backyard line, a propane heater is another way to get fast powerful heat to your pool.

Like with a natural gas heater, propane heaters run your pool water through a heat exchange while a combustion chamber burns. Cold water comes in, and warm water is returned to your pool. Gas heaters work great in combination with solar blankets. The heater heats the water quickly and the solar blanket locks in the heat.

Propane heaters rely on a propane tank to run, so you’ll have to install a large tank in your backyard that will need to be filled regularly.
