Boiler types explained

Finding the perfect fit for your home

While all boilers essentially do the same thing - providing your home with hot water and heating - there are different types of boilers on the market. Some are more suited to smaller homes while others are ideal if you have multiple bathrooms. How many radiators and taps you have also plays a role too. Learn how different boiler types work and which boiler would best suit your home and needs, with our in-depth help.

A black Worcester Bosch combi boiler with display

Combi boilers

Great for smaller homes as they can fit in a cupboard and you don’t need a hot water cylinder or cold water storage tank, so they don't take up any loft space either.

A white Worcester Bosch regular boiler with display

Regular boilers

If there are several people living in your household and you often use hot water at the same time, consider a regular boiler. They're linked to a hot water cylinder and a cold water storage tank, and are great in areas with low water pressure.

A black Worcester Bosch system boiler with display

System boilers

Designed for homes with more than one bathroom, system boilers give you a constant supply of hot water to multiple taps. There’s no need for the tank in the loft either.

Long term energy savings with a new boiler

Efficiency levels of boilers in the UK are based on how much fuel is converted into usable energy. Our boilers are 94% efficient, which means only 6% of the fuel used by the boiler is wasted. You could save £205 a year by switching to a more efficient gas boiler1.
