Nobody likes the idea that their boiler will eventually fail. But, unfortunately, these pieces of equipment don’t last forever. Instead, they often require repair.
That’s where this post comes in handy. It explores when boilers require replacement and how you can tell if they’ve reached the end of their serviceable life.
The Boiler Is Old
First, you almost always need to replace a boiler once it gets to around 15 to 20 years old. After this point, most of the internal components have become degraded and the unit simply isn’t operating as efficiently as it once was.
Sometimes, you can replace the odd part here and there. But most of the time, it is simply better value to replace the entire unit.
Strange Noises
You might also need a gas safety engineer if you can hear strange noises coming from your boiler. Usually, furnaces should hum and perhaps clang a bit when you first fire them up. But there shouldn’t be any crunching or rasping noises coming from the unit. These sounds usually indicate serious component failure and require you to address them immediately. (If you don’t, you could risk carbon monoxide poisoning)>
Changing Pressures
You may also notice the pressure on the dial on the front of the unit oscillating up and down over time. Again, this suggests an internal leak or component failure that’s making it more challenging for the system to pressurise.
If this happens, get a professional to check it out. Usually, they can swap out old parts for new ones, but not always.
Leaking Water
Water leaks are another sign of a serious problem with your boiler that could indicate failure is imminent. When water comes out of the pipes, it leads to a drop in pressure, which may prevent some boiler types from delivering hot water to your faucets.
Usually, you will see the water leaking onto the floor below the unit. When this happens, it can damage the carpet and lead to additional issues, including an inability to heat the entire home.
Higher Energy Bills
Higher energy bills are another telltale sign your boiler is on the brink of failure. Rising costs suggest it isn’t using energy as efficiently as before and needs your help to put it right.
Usually, the highest bills precede an impending failure. You may notice them rise by over 20% compared to the previous year before components finally wear out and the time comes to replace the unit.
Foul Smells
You could also notice foul smells if your boiler has an issue. Rotten egg smells indicate a serious gas leak which could be a fire hazard.
If this situation develops, shut off all the gas and electricity to your home and call emergency repair workers immediately to help you resolve the problem. Don’t leave it to fester.
Warning Lights
Finally, you might see various warning lights and error codes on the front of the unit, telling you a failure is imminent. Deal with these as quickly as you can to prevent further damage.
