What is a combi boiler?

A Combination boiler or Combi boiler is one of the most commonly installed gas central heating appliances. They are ideal for the majority of small to medium sized homes.

They heat cold water instantaneously as it passes through the boiler on its way to your hot tap.

Benefits of having a combination boiler

  • No hot water storage cylinder removing you airing cupboard creating extra potential storage space in your home
  • A combination boiler does not store water so there will never be any left over hot water that will cool down and be unused/ wasted- This will save you money!
  • Hot water demand is only on when you open the tap creating better efficiency and saving you money
  • Combi boilers are much cheaper to install due to less material being used
  • Labour costs are much less for a combination boiler installation compared to a unvented cylinder
  • These boilers can easily fit within most modern kitchen cupboards they can hide away neatly out of site
