The types of boilers available

There are 3 types to choose from. Each one has their own distinct characteristics and features. Since there are differences, each boiler type will also carry certain advantages and disadvantages, depending on your current and desired heating situation.

  • Conventional (or Regular, Heat-Only)
  • System (or Mains Pressure)
  • Combi (or Combination)

Conventional Boilers

Conventional boilers (also known as regular or heat-only) are the most traditional kind of boiler. Usually found in older homes, conventional boilers require more space as it uses both hot water cylinders and cold water tanks located in the loft.

Cold water is supplied by your mains, and moves to the boiler to be directly heated. The hot water is stored in the hot water cylinder for later use—once a kitchen or bathroom tap is turned on, hot water is drawn from this tank.

Conventional boilers are become less and less common as combi boilers have grown in popularity because they do not require large storage tanks, resulting in a smaller piping network and boiler size.

System Boilers

System boilers are similar to conventional ones in that they require a hot water cylinder and the boiler generates heat directly. However, the boiler has the main heating and hot water components integrated into it, making installation easier.

Compared to conventional boilers, there is no need for a feed and expansion cistern as well. System boilers don’t use cold water tanks as they heat water directly from the mains. As such, system boilers take up less space than conventional types.

This kind of boiler is best suited for households with a high demand of hot water or low mains pressure.

Combi Boilers

Combination types, usually shortened to combi boilers, are the most popular type used in UK households. Combi boilers provide hot water and heat without water storage tanks, and runs on gas or electricity.

Water runs through the boiler and is heated, after which it is pumped throughout your home to radiators and to bathroom and kitchen water outlets. Combi boilers heat water on demand and so hot water storage tanks are not needed; water output is diminished, however, if multiple taps are being used at once.

This kind of boiler has become a popular choice because of its advantages: the compact size and energy savings, to name a few.

Which type is right for you?

Deciding which type of boiler is right for you depends on many factors. These include:

  • Respective advantages and disadvantages
  • Price
  • Desired outcome
  • Current heating system
  • Characteristics of your house

One of the most important things to consider is which type of boiler is suited to your current house. For example, you might not have a loft or only have limited space, which means a conventional boiler will not be possible. In this case, you should opt for either a system or combi boiler.

If your house is older, it might have a traditional central heating system and as such, only a conventional boiler is available. Older heating systems are not compatible with a combi boiler so if you want to make the switch, you will have to go for a full upgrade of your whole piping network and radiator system.
