A combi or also know as a combination boiler is a single, small compact boiler that’s been designed to provide both hot water and heating. Typically a good option for space saving, the boiler is designed to heat water instantly, rather than heating and storing like a system boiler or standard boiler, which removes the need for a large hot water storage cylinder or cold water storage tank in the loft, as usually found with older boiler systems.
In order to provide instant hot water combi boilers are on constant standby and connected to the mains water supply. As soon as a tap is turned on, the boiler is ignites and it heats the water through a secondary heat exchanger, insuring you have hot water all day every day.
The combi boiler follows the same heating process as a conventional and standard boiler, but the expansion tank is within in the boiler itself, so water is heated within the boiler before being sent to the radiators like any other boilers.
So every household is different, that means each home will have their own central heating and boiler requirements. There are several advantages of having a combi boiler installed into your home, but they may not be suitable for everyone.
