Combi Boiler FAQs
Common questions about combi boilers
Is a combi boiler suitable for my home?
Combi boilers are ideal for flats and smaller homes with one bathroom. If you have two or more bathrooms and need hot water to multiple taps simultaneously, a system boiler with a cylinder may be better.
What size combi boiler do I need?
Combi boiler size depends on your hot water demand and the number of radiators. We assess your home and recommend the right output. Common sizes are 24kW to 35kW for most homes.
How long does a combi boiler installation take?
A straightforward combi boiler replacement usually takes one day. A system conversion or new installation takes longer. We give you a clear timescale before starting.
Will a combi boiler work with my existing radiators?
Yes. A combi boiler works with standard radiators. We power flush the system before installing the new boiler to remove sludge and ensure the radiators heat evenly.
What are the disadvantages of a combi boiler?
Combi boilers can struggle to supply hot water to two taps or showers at the same time. They also have no backup immersion heater if the boiler fails. For larger homes a system boiler may be better.
Which combi boiler brand is best?
We install combi boilers from Worcester Bosch, Vaillant, Ideal and Baxi. Each has different warranty lengths and features. We recommend the best combi boiler for your budget and needs.
