How gas pool heating works
A gas heater burns LPG or natural gas to heat water rapidly through a high-capacity heat exchanger. It's completely weather-independent, so it delivers heat on demand — ideal for spas and for pools you use occasionally rather than every day.
Why choose gas
- Fastest heat-up of any system — from cold to swimming quickly, whenever you want it.
- On demand, any season — not reliant on sun or air temperature.
- Compact & quiet — fits tight equipment spaces without intruding on your poolscape.
- Perfect for spas and spontaneous weekend swims.
Running costs
Gas has the highest cost per swim, but because you only run it when you need it, it's the smart choice for spas and occasional use. Many owners pair gas with solar or a heat pump for the best of both.
