Your neighbours and family may suggest them, you might choose to have one installed yourself, but when it comes to deciding on a Best Buy Combi Boiler, you should also be asking ‘Why?’
In brief, a Combi Boiler combines heating and hot water into one single unit. Unlike other types of boilers, it doesn’t require attic tanks (Open Vent) or a separate hot water storage cylinder (Sealed System). It simply heats water on demand as-and-when you require it. No storage tanks or cylinders. No hassle.
