Frequently Asked Questions
Is a combi boiler right for my home?
Combi boilers are ideal for homes with 1–2 bathrooms and up to 3 bedrooms. They're not always the best choice for larger properties with high hot water demand.
Can a combi boiler replace my old system boiler?
Yes, but it requires removing the hot water cylinder and cold water tank. Our engineers handle all of this as part of the installation.
Do combi boilers work with all radiators?
Yes — combi boilers work with any standard radiator system.
