Swimming Pool Heater Information

Natural Gas and Propane Pool Heaters

Natural gas and propane pool heaters provide an efficient way to warm your pool water to your preferred temperature, in any conditions. Gas pool heaters are assorted by the heat output, in BTU's. Manufacturers offer model sizes ranging from 100K BTU to 400K BTU. Above ground natural gas pool heaters are usually between 100-200K BTU. In-ground gas pool heaters are between 200K-400K BTU, and sized according to pool size in gallons and surface area.

Larger pool heaters will heat the water faster, but may not always be necessary. As a general rule of thumb, we recommend shopping for a natural gas pool heater with at least 100K BTU for every 10,000 gallons of pool water. Using a solar pool cover can also help reduce evaporative heat loss by 95%, decreasing the size of gas heater required and the cost to operate the heater.
