Your boiler is the heart of your home. In freezing temperatures and heavy snowfall, a reliable boiler system keeps your home warm and heated. When you live in a busy, cold place like London, a boiler is an essential. Unfortunately, like most appliances, boilers don’t last forever. The issue is that many London homeowners fail to notice the warning signs that they need a new boiler. It’s not just the annoyance of a broken boiler and the risk associated, but also the energy bill increases you will see if you fail to get a new boiler. This article will serve as a guide to help you identify the signs that you need a new boiler.
6 Signs that You Should Consider a New Boiler Installation in London
Before your boiler completely breaks down, it usually gives you some kind of warning. If you see the following problems, it is likely time for a new boiler.
1. Your Boiler is Over 10–15 Years Old
Most boilers last for a maximum of 10 to 15 years and thus, should be replaced afterwards since they become less efficient and less reliable.
2. Energy Bills are Rising
If your heating bills continuously increase but your usage is the same, your boiler may actually be the reason.
3. Requires continuous Repairs
One payment for a repair is normal. Paying for a repair more than once a year is definitely not normal.
4. Boiler makes Strange Noises
All boilers will make some noise while working; however, if it’s banging, whistling, or gurgling, then there could be a serious problem.
5. The Flame is Yellow, not Blue
The flame in your boiler should always be blue. If the flame is yellow or orange, this could be very serious. It could be a sign of incomplete combustion, which means higher chances of carbon monoxide. If this happens, call a Gas Safe registered engineer straight away.
6. Water Leaks
Leaks around your boiler could indicate serious problems. If there are leaks inside your home, there are likely some internal components that have failed. The components may need to be replaced.
