Boiler Repair Issues Warranting a Professional’s Visit

So many things can stop your boiler from delivering maximum performance. Though you can do a little tweaking and handle minor issues on your own, it is better to contact a professional technician when you’re not sure about the underlying problem.

A Leak Problem

It is never a good idea to ignore leaks and drips because the loss of water makes your boiler lose pressure. Also, a constant drip could create a short-circuit or damage components by leaving them vulnerable to corrosion. Leaks can create water damage around the boiler and even contribute to structural issues over time. Since electricity is involved, or gas which you can not legally touch anyway, you are better off calling a professional for emergency boiler repair London area. Be sure to turn off both the cold and hot water and wait for a professional to help fix the issue.


Have you ever heard an unbearable noise coming out of the boiling kettle? The problem is called ‘kittling’ and is the result of limescale buildup. It creates a sludge that restricts water flow making it difficult for the boiler to work. Obviously, you will have to deal with the causal factors to resolve the issue. While you can try to fix it yourself, it may become tricky if you don’t have the right tools or lack the knowledge about how the boiler works. A professional can flush out the whole system and get the boiler back in peak working condition.

Pilot Light Issues

If you notice the pilot light going out, it could be a faulty thermocouple. It also means that the burners don’t ignite to heat the water. A number of underlying problems may cause pilot light issues, so it is better to seek a professional’s help.

Low Boiler Pressure

The main reason for low boiler pressure is a leak. However, it could also be a malfunctioning expansion vessel. If the pressure is too low, the boiler will switch off automatically and won’t restart. To re-pressurize, you can refer to the manual, but keep in mind, there will be some instructions to follow that could be complicated. If you’re not sure about anything, it is much better to let a professional take care of the repair.

Thermostat Issues

A faulty thermostat can make it impossible for your boiler to sense the room temperature correctly. It means that the main unit will not receive correct signals to switch on and switch off. It is a good idea to troubleshoot the thermostat and check your power supply. It may also be a good idea to check the timer settings. If nothing works, call in a professional right way.

 Boilers are expensive. They are also finely tuned pieces of equipment not meant for bashing. But, if you take that thermocouple off, can you be 100% certain you can put a new one on? What if you did and the boiler still isn’t working or it works but the pressure won’t stay up? At what point will you concede you need the skills of a professional to save yourself time, frustration and bother and call the boiler expert in?
