We love the old boilers, they’re brilliantly constructed and we still see plenty of 30 year old boilers going strong. We agree that ‘if it aint broke, don’t fix it’ in regards to SOME of the golden oldies. HOWEVER and it is a massive however, they are horrifically inefficient in relation to cost of energy.
Most older boiler are complete with old systems, old radiators, old valves, old controls and 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 efficency 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 of your current boiler.
