A quick guide to Combi & LPG Boilers

Combi Boiler

A combi boiler (short for combination boiler) is a type of boiler that provides both central heating and hot water directly from the boiler without the need for a separate water tank or cylinder.

Combi boilers are compact and efficient because they heat water on demand, meaning they don’t store hot water like traditional systems, so you won’t run out of hot water unless there’s a high demand. They are a popular choice for smaller homes or flats with limited space, as they eliminate the need for a hot water tank and can be installed in smaller areas, such as a kitchen cupboard.

The key advantages of a combi boiler include:

• Space-saving: No need for a separate hot water tank.
• Efficiency: Only heats water when needed, so there’s no energy wasted.
• Instant hot water: Hot water is available whenever you turn on the tap.

However, they might not be ideal for larger homes with multiple bathrooms, as the hot water supply can be limited if many taps or showers are being used at once.

LPG Boiler

An LPG boiler is a type of heating system that uses liquefied petroleum gas (LPG) as a fuel source to heat water and provide central heating for a home or business. LPG is a flammable mixture of hydrocarbons, typically propane and butane, stored in liquid form in a tank.

LPG boilers are often used in homes or areas that are not connected to the natural gas grid. They function similarly to natural gas boilers, but instead of using natural gas, they burn LPG to generate heat. The heated water is then circulated through radiators or underfloor heating systems to warm the building.

LPG boilers are known for being efficient and can be used for both heating and hot water supply. However, they require a storage tank for the LPG, and the cost of LPG can be higher compared to natural gas.
