What is an LPG boiler?

An LPG boiler is a boiler that utilises Liquid Petroleum Gas as its fuel source; this is stored in an external tank ready to supply the boiler. Due to being 250 times denser as a liquid than as a gas, large quantities of LPG can be stored in a small space. This makes LPG boiler installation an ideal choice for various property sizes.

For convenience, an LPG tank can also be stored underground. LPG tanks usually come in capacities of 1,000 to 2,000 litres. A wide choice of LPG boiler installation options is available in the UK market.

Like gas and oil boilers, LPG boiler installation is available for combi boilers, conventional boilers and system boilers. LPG boilers are often used with a renewable energy source such as solar.

With an LPG boiler installation, you can have some of the lowest CO2 emissions available to off-grid properties – typically 20% less than the CO2 emissions of an oil boiler. LPG boilers are cheaper to install than oil boilers but can be more expensive to run.
