Which type of boiler do I need?

How do I decide which type of boiler best suits my needs?

There are 3 different types of boiler:

  • Combi boiler (or ‘combination’ boiler)
  • Regular boiler (often also referred to as a ‘traditional’ or ‘conventional’ boiler)
  • System boiler

Combi boilers provide heating and hot water directly from the boiler.

Regular and system boilers heat your central heating system directly and produce hot water for your cylinder.

Requirements Most suitable boiler

You live in a flat or bungalow (i.e. have very little or no roof space) Combi boiler

Your main water pressure is low Regular or system boiler
You want to replace an old boiler to improve an existing conventional central heating system Regular, system or combi boiler

Which boiler you need will depend on several factors, including your property and lifestyle. It will also depend on the professional advice of a Gas Safe Register installer for gas boilers, or, an OFTEC registered installer for oil-fired boilers.

Find an installer

Please remember to discuss the following with your local installer or engineer when they visit your home:

  • Have your heating and hot water needs changed since your current boiler was fitted i.e. are there more or fewer residents using the hot water? Have you added an extension or a loft conversion?
  • We recommend system flushing and treatment to ensure your heating system efficiency over time - ask for more details.
  • How the different controls options can give you an even more efficient heating system and save energy and money.
  • What is the impact of having a new shower installed - will it work off the existing hot water system or is it electrically powered?
  • How can solar water heating or heap pump technology benefit your efficiency and carbon footprint?
  • What funding schemes are available i.e. Green Deal, Eco, Renewable Heat Incentive.
