Converting from a system or regular boiler to a combi is a popular upgrade that frees up valuable space by removing the hot water cylinder and cold water tank. Norvera arranges boiler conversions through Gas Safe registered installers with a clear, fixed price and honest advice on whether a combi is right for your home.
A conversion involves removing your existing boiler, hot water cylinder, and (if applicable) cold water tank in the loft. The new combi boiler is connected directly to the mains water supply and the existing radiator pipework. Some adjustments to pipework are usually required, which makes a conversion more complex and slightly more expensive than a like-for-like replacement.
A combi boiler works best in properties with one or two bathrooms and adequate mains water pressure. If your home has three or more bathrooms or multiple showers that may run simultaneously, a system boiler may be the better choice. Our team will give you an honest assessment before you commit.
