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. 

Liquid Petroleum Gas (LPG) is a combination of propane and butane stored under moderate pressure. It is widely available in the UK and is recognised as a low carbon and low polluting fuel.

Due to being 250 times denser as a liquid than as a gas, a large quantity of LPG can be stored in a small space. This makes LPG boiler an ideal choice for installing in a wide variety of property sizes. For convenience, the LPG tank can also be stored underground. LPG tanks usually come in capacities of 1000 to 2000 litres.

There a wide choice of LPG boiler options available on the UK market. These include dedicated LPG boilers, standard natural gas boilers that can be adapted using an LPG conversion kit, and boilers such as Viessmann’s Vitodens 200-W which automatically adapts to the properties of LPG without the need for a conversion kit. 

Like gas and oil boilers, LPG boilers are available as combi boilers, conventional boilers and system boilers. 

LPG boilers are often used in conjunction with a renewable energy source such as solar.

LPG boilers 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.

LPG boiler tanks

To install and use an LPG boiler at your property, an LPG storage tank will be required. These tanks will need to be refilled periodically, either by a tanker truck that you arrange to visit your property or from smaller LPG cylinders or bottles.
To ensure you are aware of when you are running low on fuel, most LPG tanks are fitted with a device that warns you when it will need refilling.

An LPG tank can either be installed above or below ground and typically start as low as a 1m by 2m footprint. The position and regulations surrounding LPG will need to be taken into consideration when installing the LPG tank. However, this is something which we are able to advise you on.

Cost Calculation

LPG boiler costs

The average annual cost for heating and hot water using LPG in the UK is £796, this is based on a household consuming around 12,000 kWh a year. This figure is derived by using the average cost of LPG across the UK in 2020 and then multiplying this by the amount of kWh used on average by a medium gas-energy user according to Ofgem.

LPG boilers are usually more expensive to run than oil boilers. However, LPG boilers are cheaper to install and can easily be combined with renewable energy sources. LPG is also a highly efficient fuel so you get a good return on every unit of energy.

By changing to a new A-rated LPG boiler, you could be quite comfortably saving anywhere between £300 – £600 per year.

It should be noted that the cost of running an LPG boiler is dependent on a number of factors, including:

  • Whether you choose to rent or buy the LPG storage tank
  • The size of your household and your hot water demands
  • The size of your property and the number of radiators you have
