Q What kind of fuel does your boiler use?

What Size Central Heating Boiler Do I Need?

One of the key deciding factors for the size of boiler needed is the number of radiators.

A small flat will only need a small boiler to provide the best economy.

A three to four-bedroom home usually has around ten radiators, and so a 24-30 kW boiler is generally recommended.  

A larger house with more radiators or additional bathroom will typically need a boiler in the range of 30-35 kW.

Which Type of Central Heating Boiler Is Right for Me?

If we were to pick just two boilers, then we’d go for the  Worcester Bosch Greenstar 8000 Style Combi Boiler and then the Viessmann Vitodens 050-W. These combi boilers aren’t cheap boilers, but provide exceptional value for money, excellent reliability, and high energy efficiency levels.

Once you have your boiler in place, make sure you have the best boiler and central heating cover to give you complete peace of mind. We’ve provided a complete guide to help you make the right choice for your boiler system.
