Safety & Efficiency – a well-maintained and regularly serviced boiler will work safely and more efficiently. If a boiler is incorrectly calibrated, it may be working harder than it is designed to, thus increasing your bills unnecessarily. Fossil fuels (such as natural gas) could produce poisonous carbon monoxide (CO) if they are not working properly, so to keep your family safe, your Gas Safe registered engineer will check your boiler’s general condition and CO levels.
Most older boilers are complete with old systems, old radiators, old valves, and old controls and are likely full of sludge if they haven’t been flushed in recent years. With all these things considered, replacing a boiler that has an energy efficiency rating lower than an A is the best possible way to minimise energy costs. If set correctly, the projected figures are that it can save you up to 30% on your heating bills, depending on the age and rating of your current boiler.
