As temperatures drop, experts are emphasizing the importance of regular combi boiler maintenance and efficient usage to manage rising energy costs. Maintenance professionals note that boilers operate continuously, often facing issues from limescale in water and dust accumulation in fans and expansion tanks. It is recommended that periodic maintenance be performed at least once a year by authorized services to ensure components like circulation pumps and three-way valves function correctly. To reduce natural gas bills, users are advised to avoid running boilers at unnecessarily high temperatures, as higher settings do not always equate to better economic efficiency. Effective energy saving also depends on home insulation, preventing heat loss through windows and doors, and ensuring that radiators are not obstructed by furniture or heavy curtains, which can impede heat circulation. Recent expert advice suggests that regular maintenance can lead to savings of up to 30 percent on natural gas costs. Technical procedures to achieve this include checking water and heating combustion, verifying water tightness, cleaning the combustion chamber burner, and inspecting electrical and electronic connections. Other essential steps involve lubricating the flue fan, adjusting expansion tank pressure, and cleaning the dirt trap filter in the heating return line. For condensing boilers, cleaning the condensation water reservoir is also required. Furthermore, cleaning radiators is considered critical for efficiency, as rust particles can accumulate and clog filters. While cleaning may only be necessary every two years in areas with clean water, annual cleaning is recommended to prevent long-term damage and maintain performance.
