When it comes to choosing a new boiler, it’s important to ensure that the new system fits into your property and runs efficiently and effectively. To assist we have put together a guide to help you choose your new boiler. There’s three main types of boilers including system boilers, combi boilers and regular boilers, each system has its own range of advantages and what situation they work best in.

So should you require a new boiler fitted into your existing system, it’s important to consider your pipework and radiators, as should they be old and worn, they could cause damage to your new boiler.

Regular boiler

Regular boilers are also known as conventional or traditional boilers, they’re suited to home which already have a traditional heating and hot water system which is linked to separate hot water cylinders as well as tanks that maintain the water level of the central heating system.

Regular boilers can be the best option should you need to replace an existing boiler, if you’re property includes an older boiler system then it may not be able to cope with the higher water pressure that’s delivered by the system or combi boilers.

Here’s the top benefits of regular boilers

  • Ideal if your property has more than one bathroom
  • A great choice when it comes to water pressure being low
  • Great for homes where a lot of hot water is used at the same time
  • Compatible with solar water heating systems for lower carbon footprints and lower energy costs

System boiler

These boilers need a cylinder for storing water, however, major heating and hot water system components are built into the boiler themselves, making them easier to install. With this system there’s no requirement to have a tank in the loft, so it’s an option for homes with no loft space or where space is earmarked for conversions.

System boilers are also compatible with solar water heating systems and these deliver a number of environmental benefits including lower energy bills.

The benefits of system boilers

  • Perfect for homes with multiple bathrooms
  • No requirement for a separate water tank in the loft, creating more space and less worry about leaks or frost damage
  • Economical to run
  • Constant supplies of hot water to a number of taps at the same time
  • Built in components making installations quicker and neater

Combi boiler

A combination boiler includes both high efficiency water heaters and central heating boilers, both in single compact units, combi boilers heat water directly from the mains when you turn the tap on, so there’s no need for a hot water storage cylinder or a cold water storage tank in the roof space.

Combi boilers are cost effective and energy efficient as the water is heated straight away, rather than being heated and then stored in a cylinder. Extra benefits include hot water being delivered by mains pressure, so you can have a power shower with no requirement for a separate pump.

The advantages of combi boilers includes

  • They’re compact in size, so they’re great for smaller properties
  • No need to have a hot water cylinder, so there’s more space for living
  • No risk of the pipework freezing
  • Ideal where there’s little loft space
  • No cold water tank storage, so there’s more loft space
  • Less pipework required so the overall installed is cheaper
