Boiler types explained - Regular, combi and system

Posted on 7/20/2019

Choosing to install a new boiler in your home is a big decision and you may be unsure where to start. To make things easier, we’ve broken down the different types of boiler.

Combi boilers

A combi, or combination boiler, provides households with both central heating and hot water in one unit. It works by instantly heating water from the mains on demand, which means you only heat water as and when you need it. With combi boiler there is no waiting around for the tank to reheat and no chance of running out of hot water.

The single-unit combi boiler is compact and can fit into small spaces such as a kitchen cupboard. This makes a combi boiler well-suited to small to medium-sized homes where space is limited. Because you only heat water when you need it, combi boilers are both cost and energy efficient.

Regular Boiler

Regular boilers are ideal for homes that already have a traditional central heating system - this includes a boiler, radiators and a hot water cylinder.

They normally heat water in a hot water cylinder, taking cold water from the tanks located in the loft. Water is then circulated from the hot water cylinder to supply hot water throughout the home and to the radiators for heating.

Regular boilers are a good choice for larger homes, especially those with two or more bathrooms but hot water can run out

Regular boilers are a good choice for larger households with two or more bathrooms. This is because their hot water is supplied from a storage cylinder rather than the mains.

Regular boilers can therefore serve multiple taps and showers at once without a decrease in water pressure or temperature. However, as with a system boiler, your household will only be supplied with as much hot water as your storage cylinder can hold. Once the hot water is used up, you will have to wait for it to re-heat.

System Boiler

Like regular boilers, system boilers are ideal for homes with a traditional heating system, which includes a boiler, radiators and a hot water cylinder.

One of the main advantages is that system boilers don’t need a separate tank in the loft to feed the central heating system as they take water directly from the mains. This means they are a great option to save space in your property and provide a steady, high pressure supply of hot water to any number of taps at the same time.

A system boiler is a newer version of the traditional heat-only system, the difference is that it incorporates some extra components inside the boiler, so there’s no need of them being added externally, saving space and money.
