Contact Pool Supply DepotFrequently asked questions
Is a 400K BTU heater always the best choice?
Not necessarily. Heater sizing depends on pool and spa volume, desired heat-up time, climate, and fuel capacity. An installer can check whether a larger heater is appropriate.
Are the natural gas and propane models interchangeable?
No. Choose the model made for your available fuel and confirm installation requirements before ordering.
Heater installation, fuel connections, venting and permitting should be reviewed by a qualified professional. Product selection is subject to the manufacturer's installation instructions and local requirements.
