Combi Boilers
What Is the Best Combi Boiler?
If you’re wondering how to choose the right combi boiler, there are a few factors to consider. As a general rule, the more hot water you use, the higher the kilowatt rating you’ll need. For example, if you live in a flat or house with up to ten radiators and one bathroom, a 24-27kw combi boiler is the ideal choice.
For homes with up to fifteen radiators and two bathrooms, a 28-34kw combi boiler is best. Large homes or businesses with up to twenty radiators and two or more bathrooms should opt for a 35-42kw boiler.
Combi boilers are often the most energy-efficient choice in any central heating system, with options available to suit all budgets and home configurations. Check out our Boiler Buying Guide for more details on these and other boilers.
