When considering which boiler is right for you, there are certain factors to look out for. Depending on the size of your property and the demand for hot water throughout the day, different attributes may suit you better. There are three main types of boiler – conventional, combi and system boilers.
A combi boiler (or combination boiler) is the most commonly used boiler in the UK as it provides heat for both the central heating system and the hot water system on demand... as and when you need it.
