Different types of boilers you can install

Is it time to install a new boiler in your home? A new boiler is a large investment, so it is important you decide on the right model for your home. The three main types of boilers you will come across are combi, conventional and system boilers, each with their own pros and cons. 

As well as this, you will hear about condensing boilers. As of 2007, all boilers are required to be condensing, as it is much more efficient. Not only is this better for the environment, but it also helps to save you money!

Conventional boilers

Conventional boilers operate with two water tanks, which will be located in your loft space. They can meet a very high demand for hot water, making them best suited to larger homes and big families. 


  • Can meet a high demand for hot water
  • Hot water is available form several taps at once, without affecting water pressure
  • Doesn't rely on good mains pressure
  • Compatible with regular solar water heating systems


  • Requires the most loft space
  • Hot water needs time to heat up before it can be used
  • When you empty the tank, it needs to refill and reheat
  • Heat can be lost while the water is stored in the tank unless it is well insulated

System boilers

System boilers only require one water tank for hot water. As a result, they require less space than conventional boilers, while still have many of the same benefits. They can also meet a high demand for hot water, so are great for large homes and large families.


  • Can meet a high demand for hot water
  • Doesn't require two water tanks so saves some loft space
  • Can be compatible with solar water heating systems
  • Doesn't rely on good mains pressure
  • Multiple taps can be used at the same time, without affecting the pressure


  • Water needs to heat up before use
  • When the cylinder is emptied, it needs to refill and reheat

Combi boilers

Combi boilers only require the boiler unit itself and no sperate components. This makes them ideal for smaller homes with less available space, although they struggle to meet a high demand for hot water. They work directly from mains water, heating water immediately when you need it.


  • Requires no loft space
  • No need to wait for your hot water to heat up in a tank
  • Very cost effective and efficient 


  • Relies on good mains water pressure
  • running several taps at once may affect water pressure
  • Will struggle to meet a high demand for hot water
