Which new system suits your home?
Here are some things to consider when choosing your new boiler:
-
How many bathrooms are in your home?
-
Are there more than two people living in the house?
-
Is it a small, large or older home?

Combi Boilers
A combi (short for combination) boiler is the most compact option because it generates both your heating and hot water from a single unit, usually wall hung. With a combi boiler there’s no need for a separate hot water tank.
How do they work?
Combi boilers are connected to the mains cold water supply and can heat water on demand. They burn fuel when you ask for hot water and have an integral heat exchanger that then gets hot enough to instantaneously heat the cold water from the mains supply as it flows over it.

Conventional Boilers
Also known as a ‘regular’ or ‘heat-only’ boiler, conventional boilers are one of the types of boiler that has a water tank. They heat up your radiators directly and connect to a separate cylinder or tank to provide hot water.
How do they work?
As with combi boilers, a heat exchanger warms water when fuel is ignited, but with a conventional boiler a pump transports the water to a storage tank. This hot water then flows through to radiators to heat them, or into your taps when you switch them on.

System Boilers
Like conventional boilers, system boilers need a hot water cylinder. However, unlike conventional boilers, they don’t need a cold water tank, and components like pumps and valves that are separate in conventional boilers are built-in with a system boiler. You might also hear system boilers being called ‘closed vent’ or ‘system sealed’ boilers.
How do they work?
System boilers work in the same way as conventional boilers, it’s just the components are slightly different. Think of them as the modern upgrade to a conventional boiler.
