New combi boilers

A new combi boiler is a high efficiency water heater and a central heating boiler combined in one compact unit, hence the name ‘combi’.

This means you don’t need a hot water cylinder or water tank, freeing up space in your home.

Combi boilers are suitable for most houses where a few people require water at the same time. With so many benefits combi boilers make up well over half of all new boilers fitted in the UK every year.

New system boilers

A system boiler only requires a cylinder for storing your hot water in, not a header tank in the loft.

The major heating and hot water system components are built into the main boiler itself, making this type of boiler generally quicker and easier to install.

System boilers are also great for homes that require hot water in more than one place at the same time.

New conventional boilers

Conventional boilers are also known as regular boilers, traditional boilers or heat only boilers. They require both a tank and a cylinder.

These boilers are suited to homes that already have a traditional heating and hot water system that is linked to a separate hot water cylinder in place.

These boilers also require a cold water storage tank to feed the hot water cylinder as well as another tank that preserves the water level of the main central heating system.

Conventional boilers are more common in older properties with a heating system that hasn’t been updated recently; consisting of a boiler, heating controls, a hot water cylinder, a cold water storage cistern plus a feed and expansion cistern.

FAQs

How do combi boilers work?

Combi boilers work by taking water directly from the mains and heating it producing a continuous supply of water. This makes new combi boilers more energy efficient, as they don’t store hot water in a separate tank.

How do system boilers work?

System boilers work by pumping hot water from the boiler through the heating system to the hot water cylinder and radiators around your home by removing the need for a feed and expansion cistern. A hot water storage tank will always be required with a system boiler, as it needs somewhere to store the water it has heated.

How do conventional boilers work?

A conventional boiler works by igniting fuel to heat the water stored in the hot water cylinder, which is fed by the cold water storage cistern. The boiler then passes water to the central heating through a feed and expansion tank.
