As temperatures drop in October, your boiler becomes one of the most relied-upon systems in your home. But how do you know when it’s time to replace it? At Forte Heating Services, our qualified heating engineers help homeowners across Farnham, Surrey, and Hampshire decide when to upgrade to a more reliable, efficient system.
Here are some tell-tale signs your boiler might be due for a replacement, straight from our experienced heating engineers.
1. It’s Over 10–15 Years Old
Boilers typically last between 10 and 15 years. If yours is approaching this age or older, it’s likely running less efficiently and may no longer meet modern safety or energy standards. Even if it’s still working, an older system could be costing you more than it should in running costs. A qualified heating engineer can assess the condition of your current system and help you determine if a replacement is the best option.
2. Rising Energy Bills
Have your gas bills increased for no obvious reason? An inefficient boiler uses more energy to heat your home, which directly affects your wallet. Replacing it with a modern, energy-efficient model can help reduce your monthly heating costs. Our heating engineers are trained to evaluate system performance and suggest suitable upgrades.
3. Frequent Repairs
If your boiler regularly breaks down or needs new parts, it could be more cost-effective to invest in a new one. Not only do frequent repairs add up, but they can also leave you without heating when you need it most. Our heating engineers can help you weigh up the costs of ongoing repairs versus a complete replacement.
4. Strange Noises
Unusual sounds such as banging, whistling, or gurgling could indicate problems with internal components, limescale build-up, or trapped air. While some noises are fixable, recurring sounds may be a sign your system is wearing out. One of our expert heating engineers can carry out diagnostics to pinpoint the issue.
5. Uneven Heating
If some rooms in your home stay cold no matter how long the heating is on, or your hot water takes ages to heat up, your boiler could be struggling to keep up. A new installation could restore comfort and consistency. Let a heating engineer assess whether your current setup can be adjusted or needs replacing.
6. Yellow Flame or Warning Lights
A healthy boiler should burn with an intense blue flame. If it’s yellow or you notice warning lights on the boiler display, turn it off and call a Gas Safe registered heating engineer immediately. These issues may indicate carbon monoxide risk and should never be ignored.
