Combination Boilers

A Combination Of Convenience, Efficiency And Performance

Combination (combi) boilers are the most popular in the UK market and can be found in around 70% of our homes.

Providing central heating and instant hot water without the need for a hot cylinder, combi boilers work by heating mains cold water instantly as it flows through the unit.

Combi boilers are both water and energy efficient as they only heat the amount of water that is needed.

However, as these types of boiler heat cold water directly from the mains, water flow is reduced when two or outlets are in use at the same time.

For example, shower flow and performance may be compromised if a hot tap is run in another room or if a dishwasher of washing machine is in use.

Due to this combi boilers are recommended for small family homes with only one bathroom for best performance.

Advantages of combination boiler heating systems:

  • Instant and unlimited domestic hot water
  • Combi boilers are compact and maximise space
  • They can free up your loft space for renovation as a cold water tank is not required
  • A hot water cylinder is not required
  • Combination boilers are relatively easy to install and do not require as much labour in comparison to sealed system or open vented units

Disadvantages of combination boiler heating systems:

  • Combination boilers cannot supply more than one outlet at a time without loss of flow
  • Combination boilers often offer a lower flow rate that boilers which utilise a hot water cylinder

A combi boiler may suit you if:

  • You have a small family with one or two children
  • You live alone or with a partner
  • You live in a house or flat with only one bathroom
