The main types of boilers are Combi, System, and Regular boilers. Combi boilers provide instant hot water without a tank, System boilers use a separate hot water cylinder ideal for homes with multiple bathrooms, and Regular boilers are traditional, reliable options suited to larger properties with high hot water demand.
Boilers should be serviced at least once a year to maintain peak efficiency, prevent costly breakdowns, and ensure safety. Annual servicing can also extend the lifespan of your boiler and keep your warranty valid.
Common signs include cold or unevenly heated radiators, unusual noises from the boiler, leaks, error codes, or a sudden drop in hot water pressure. Noticing any of these early can prevent more serious and expensive issues.

Gas and LPG are widely used for modern boilers, providing reliable and efficient heating. Oil is often used in rural areas without access to mains gas. All fuel types can work with Combi, System, or Regular boilers, and a qualified engineer can advise on the best option for your property.
