COMBI BOILERCombi boiler is a single compact unit which produces instant hot water and heating on demand. Combi boilers are most popular heating and hot water solution across the UK with a wide range of models to suit your home and living conditions. You only pay to heat water as you use it.
HOW COMBI BOILER WORKSCombi boiler heats water directly from main supply, when you turn on your tap you get instant hot water running. Combi boilers are cost effective and energy efficient as water is heated instantly rather than being heated and stored in a hot water cylinder, which cuts energy bill costs. As water is delivered at mains pressure, which could get you a powerful shower flow without a separate pump. Combi boiler contains a expansion tank so water is heated within the boiler before being sent to radiators. Where as a conventional boiler has a separate expansion tank to heat water which is usually in loft and connected to boiler using external feed which acquires a lot of space.

- Ideal where there is little or no loft space
- No need for hot water cylinder provides increased living space.
