Which boiler does your home need?

While different kinds of boilers all do very similar jobs, it is still important to choose the right one for your home. If you are considering getting a new boiler, this is the best place to start your research.

As of 2004, all new boiler installs are required to be a form of a condensing boiler. This helps the homeowner to save money long term as they are much more efficient (90% at least) and waste less energy than non condensing boilers. The following are all forms of condensing boilers.

Conventional boilers (also called regular/traditional boilers)

Does your home have…

  • High demand for hot water?
  • An older radiator system?
  • Two or more toilets/bathrooms?
  • Low water pressure?
  • Plenty of free loft space?

If the answer to some of these questions is yes, then a conventional boiler is right for you.

Conventional boilers require two water tanks in the loft and a water cylinder, usually in an upstairs cupboard. This tends to make them unsuitable for smaller homes as they require a lot of space.
However, they can meet a high demand for hot water which makes them suitable for large homes.

System boilers

Does your home have…

  • Two or more toilets/bathrooms?
  • A very high demand for hot water?
  • Minimal extra space (e.g. no loft space)?
  • Low water pressure?

If the answer to some of these questions is yes, then a system boiler is right for you.

System boilers do not require water tanks and only need one water cylinder. This makes them more suited for smaller homes, as all other components are built into the boiler itself.
They are also cheaper and easier to install, as they have less components.

Combination (combi) boilers

Does your home have…

  • Minimal/no available space?
  • Good mains water pressure?
  • One bathroom?
  • A low demand for a lot of hot water simultaneously (e.g. two hot taps running at the same time)?

If the answer to some of these questions is yes, then a combi boiler is right for you.

Combi boilers are the most popular boiler installed in the UK, as they are less expensive than conventional and system boilers and they're easier to install and take up little room. They heat water instantly when it is needed, rather than storing it, so there is no need for a water tank or cylinder.
They deliver water at mains pressure and running multiple taps at the same time will decrease the water pressure, so they are suited for smaller homes with lower hot water use.
