Gas pool heaters are the most popular system for heating swimming pools. Today you can find new gas heaters with much higher efficiency than older models with brands such as Rheem, Jandy and more. Gas pool heaters use either natural gas or propane. As the pump circulates the pool water, the water drawn from the pool passes through a filter and then to the heater. The gas burns in the heater’s combustion chamber, generating heat that transfers to the water that’s returned to the pool. They’re most efficient when heating pools for a short period of time, and are ideal for quickly heating pools. Unlike heat pumps and solar pool heaters, gas pool heaters can maintain any desired temperature regardless of the weather or climate. When selecting a gas pool heater you need to consider size, efficiency and cost.
