CEE recommends replacing a boiler when you are 25 years of age or older. A boiler can operate beyond this age, but it will operate less efficiently and is more likely to need more frequent repairs as it ages. This means that you'll pay more to heat your home as your boiler ages. Many people don't even know that their boiler requires proper maintenance to extend its productivity and lifespan.
Most industrial boilers tend to last between 15 and 25 years, on average, and 25 years are high-end. It is common for oil and gas boilers to remain in operation for 11 to 27 years. Electrical systems tend to fail sooner. Natural gas has become the most common energy source for boilers in most parts of the country.
Most boilers will have an average lifespan of between 15 and 25 years. If your boiler is 23 years old and requires major repairs, it may be time to consider a new boiler. When it comes down to it, you can go on for a long time without a boiler, especially considering the UK winters. Another example is when you constantly change controls or participate in “thermostat wars” with your partner or roommate, which also contributes to reducing the life of the boiler.
A combined boiler can have a thermal efficiency of 98% when new, and a condensing boiler can have 92-95% depending on the model and brand. If you can't find the budget for your replacement boiler, you can consult the UK's green initiative for its new boiler grant. Rather than waiting for a total failure, ATI of New York outlines some telltale signs to pay special attention to if you're considering replacing your boiler. A complete conversion of the system to a modern combined condensing boiler will eliminate the need for an external central heating pump, zone valves, head tanks, hot water cylinder and a two-channel programmer.
It's not uncommon for homeowners or facility managers to wait until a boiler breaks down completely before replacing the unit. We replaced many of the ideal combination boilers around the age of 8 and up, the Bosch combination boilers in Worcester around the age of 12. This way, in addition to scheduling an annual maintenance review with your local heating engineer, you can make your boiler last longer. If you raise the temperature to compensate for the sudden drop, you're only over-igniting your old boiler, and that's considered a misuse of the thermostat. These tend to build up and create blockages in the storage tank and pipes that affect the performance of the existing boiler.
Obviously, the problem with that is that they usually decide to break down at the worst possible time, then you'll have to wait while you organize the boiler quotes. Even if your boiler is still operating after 10 to 15 years, it's a good idea to start considering replacing it, since its efficiency levels will have decreased. Before installing the boiler, it's best to consult your heating engineer about the best option for your home. Good boiler installers usually have an advantage over time, they specialize in boiler installations, so they are experts in what needs to be done.
