When it comes to boilers, there are a range of options available. The combination boiler is the most popular boiler choice throughout the UK. But does this mean it will be the right choice for you? Here at K and M Maintenance, we are Preston based boiler and gas experts. As a result, we have produced this guide to the advantages of combination boilers.

advantages of combination boilers

On demand

Combination boilers work on demand. This means that unlike conventional boilers, the combination boiler supplies heat to your radiators, as well as hot water, whenever required. This works by heating the water as it is supplied from the mains and directing it around your systems.


Because a combination boiler heats both the water for the radiators, as well as the taps, on demand, it does not require any storage. Conventional boilers make use of a storage cylinder for storing hot water to be used throughout the day. This gave rise to the common phrase “don’t use all the hot water!” With a combination boiler, this is actually impossible, as water is not heated and stored for later use, it is simply heated when needed.


Combination boilers are a lot smaller than conventional boilers. This is partly because of the lack of storage cylinder, which also means less pipework, but also because they tend to be less bulky. As a result, your combination boiler can be positioned in a range of more convenient places, rather than being stored away in the attic.

Simple installation

Generally speaking, installing a combination boiler is easier than installing a conventional boiler. This is because there is less pipework required. As a result, installing a combination boiler can actually be cheaper because it takes less time.

Water Pressure

Another advantage to the combination boiler is the water pressure. Because a combination boiler draws water directly from the mains and heats it before directing it through the system, there is never a drop in water pressure. When compared to a conventional boiler, that may drop in pressure when the hot water cylinder begins to run out of stored hot water, this is a big advantage.

In summary

Combination boilers are a great option for a range of homes, and there are many advantages of combination boilers. If you are looking for a new boiler installation, or need more advice, why not contact the experts at Preston based K and M Maintenance?
