How Does an LPG Boiler Work?
LPG boilers work similarly to natural gas boilers but use LPG as the fuel source. When the boiler is activated, LPG from the storage tank flows into the boiler and is ignited. The combustion process generates heat, which is then transferred to water that circulates through radiators, underfloor heating, or hot water taps, depending on the system’s configuration. The key components include:
- Burner: Where the LPG is ignited to produce heat.
- Heat Exchanger: Transfers heat to water or air, which is then distributed throughout the home.
- Water Circuit: Carries hot water through radiators or to taps.
The result is a highly efficient and responsive heating system that can deliver steady warmth and hot water on demand.
