Important factors include pool and spa volume, desired temperature rise, climate, fuel type, available gas-line capacity, electrical service, plumbing size, altitude, venting requirements, indoor or outdoor installation, and local code requirements. A higher-BTU heater can heat water faster, but it must still be matched to the gas supply and installation conditions.\u003c\/p\u003e\u003ch2\u003eNatural Gas vs. Propane Pentair Heaters\u003c\/h2\u003e\u003cp\u003eAlways order the heater for the correct fuel type unless a manufacturer-approved conversion kit is specifically available for that exact model.
