Which Boiler Is Right for You?

Choosing the right type of boiler depends on your home, your hot water usage, and your existing heating setup. Here’s a breakdown of the main types:

Combi Boiler

Combi (Combination) Boilers

Best for smaller homes and flats

  • Compact, all-in-one unit
  • Provides heating and hot water on demand
  • No need for a hot water cylinder or loft tanks
  • Fast, efficient, and cost-effective
  • Ideal for homes with 1 bathroom

Perfect if you want to save space and simplify your system.

System Boilers

System Boilers

Great for medium to large homes with higher hot water demand

  • Heats water and stores it in a cylinder for later use
  • Delivers hot water to multiple taps at once
  • No cold water tank required
  • More efficient than a regular boiler
  • Requires space for a hot water cylinder

Ideal if you have more than one bathroom or a busy household.

Boiler cylinder

Regular (Conventional) Boilers

Best for large homes or where older systems are in place

  • Requires a hot water cylinder and cold water tank (often in the loft)
  • Good for low-pressure areas
  • Compatible with solar water heating
  • Great for homes with traditional heating systems

Suitable for properties where the existing pipework and radiators are designed for this setup.
