Combi Boiler

Combination boilers are the most common type of boiler used in the UK. Combi boilers are hugely popular as they don’t require any external parts such as water tanks or cylinders. There are electric or gas combi boilers available.


  • They don’t take up much space
  • There is no need for a water tank
  • You get unlimited heat and hot water whenever you need it


  • The water pressure might be reduced if you need to use more than one tap at the same time
  • Combi boiler installation is slightly more complex

Suited to almost any home but are better suited to homes where multiple people won’t be using a lot of hot water at the same time.

System Boiler

Also known as sealed system – come with a water cyclinder which will usually be installed into an airing cupboard, and no water tank.


  • There is no need for a water tank
  • You can use multiple taps for hot water at the same time


  • You will need to find room to fit the cylinder
  • You don’t get hot water instantly
  • When the hot water runs out you will need to wait for it to reheat

Suitable for homes which require hot water in more than one room at the same time.

Conventional Boiler

Also known as open-vent or regular – come with both a water cylinder and tank.


  • You can get hot water from multiple taps at the same time


  • When the hot water runs out you will need to wait for it to reheat
  • You will need to find space to fit the cylinder and tank

Suitable for homes that require hot water in multiple rooms at the same time.
