Whether your pool is the site of the neighborhood Memorial Day cookout and "cannonball" contest, or your remedy to a long, stressful day, keeping it at a comfortable temperature is key. No one wants to swim in a pool that's too cold. On the other hand, a pool that's too warm is not refreshing.

Propane pool and spa heaters offer greater than 80 percent efficiency, and temperature accuracy within 1°F to keep you comfortable.
