The size of your boiler will depend on the size of your home and your hot water needs.

Combi Boilers

Combination (or ‘Combi’) boilers are currently the most popular type of boiler in the United Kingdom.

They can handle hot water for your taps, shower, and central heating system at the same time. The supply for everything comes directly from one unit. They are considered ideal for smaller homes, particularly those with just one bathroom.

Benefits

  • Combi boilers can provide large amounts of hot water, instantly.
  • They only heat the water you use, making them economical and environmentally friendly.
  • They are a great way to save space. There is no need to install a separate hot water tank or cold-water cylinder.
  • With few additional parts, they can usually be installed quickly.
  • Can be remotely controlled, with a new installation.

Considerations

  • If you have low water pressure, multiple taps being used at once can slow down the heating system.
  • Combi boilers take a few more seconds to get going when heating water.

Conventional Boilers

Conventional boilers are also known as regular or heat-only boilers.

They’re the traditional way to heat a home or workplace. They send a reservoir of heated water into your radiators, via a hot water cylinder that acts as a reserve. These boilers are better suited to larger homes and buildings, especially those with more than one bathroom.

Benefits

  • Conventional boilers are ideal for larger UK homes with high hot water demand.
    They can supply hot water to multiple taps at the same time, making them suitable for households with more than one bathroom.

  • They work with a hot water cylinder and cold-water storage tank, helping to maintain good water pressure even in homes with low mains pressure.

  • Conventional boilers are well suited to older heating systems and are often the best option when replacing an existing regular boiler.

  • They are compatible with modern heating controls, including smart and remote thermostats, when installed as part of a new system.

Considerations

  • A hot water cylinder and a cold-water storage tank are required, so more space is needed, typically in an airing cupboard and loft.

  • Installation can be more complex than a combi or system boiler due to the additional components.

  • Hot water supply is limited to the amount stored in the cylinder, so you may need to wait for it to reheat once used.

System Boilers

System boilers are similar to conventional boilers.

However, they have some parts that are usually external built in to them. There’s no need for a separate feed and expansion tank with a System. They’re ideal for mid-sized to large homes and for homeowners who want to free up some extra space in their loft.

Benefits

  • System boilers are well suited to medium and large UK homes with more than one bathroom.

  • They provide a strong, consistent supply of hot water to multiple taps at the same time.

  • Key components such as the expansion vessel and pump are built into the boiler, allowing for a quicker and tidier installation than a conventional boiler.

  • They work efficiently with a hot water cylinder, making them ideal for households with higher hot water demand.
  • System boilers are compatible with modern heating controls, including smart and remote thermostats, when installed as part of a new system.

Considerations

  • A hot water cylinder is required, meaning additional space is needed, typically in an airing cupboard.

  • If the stored hot water is used up, you will need to wait for the cylinder to reheat. System boilers are not suitable for homes with very low mains water pressure.
