Gas Pool Heaters

The greatest benefit of gas pool and spa heaters is that they heat your pool and spa in minutes or hours versus the hours or days required initially to warm the pool with a heat pump. Gas heaters are ideal if you don't use your pool or spa on a daily basis, and just want to heat your pool or spa as needed.

Another benefit of gas pool heaters is they perform well in any climate. They'll heat your pool and spa on the coldest of days versus the limits of a heat pump.
