Troubleshooting: Boiler Issues and How to Fix Them: Part Two

By 3rd February 2017TrustATrader Blog

Previously we looked at three of the most common boiler issues, and how to fix them. There are a number of boiler issues that can prevent your central heating and hot water systems from working efficiently, particularly in colder weather. In our final blog in the series, we look at three more common boiler issues, and what you should do if you experience them.

Problem 4: Boiler Switches Off

There are several problems that could cause your boiler to switch itself off including faulty thermostat, air in the system, a frozen condensate pipe, or low water pressure.

Quick fix: If the temperatures outside are very low, you may have to defrost your condensate pipe. Alternatively, bleeding your radiators could help to remove excess air from the system.

Call your water supplier if you notice that the water flow from your tap is slower than normal. If this is the case, the problem could be down to low water pressure; phone your supplier to see if they are aware of any issues locally.

Problem 5: Low Pressure

If you have a pressurised system, your boiler may be losing pressure. When the pressure drops below a certain line, your boiler will stop working properly.

Quick fix: You may be able to return pressure to your boiler yourself using an air pump; check your user manual for instructions.

Call a plumber if you are unsure about re-pressurising your boiler. They should be able to diagnose the cause and prevent it from happening in the future.

Problem 6: Leaking or Dripping Boiler

Age is the most common cause of a leaking or dripping boiler, although it is possible that pipe damage can be caused by freezing pipes in prolonged cold temperatures. If your boiler is in an exposed area, such as a loft, make sure that it is well insulated and regularly used to prevent pipes from freezing.

Call a plumber. Even if you can identify the source of the leaking or dripping, it is important that you call a plumber to repair cracked or damaged pipes, to maintain the efficiency and safety of your boiler.

It is very important that you don’t work on your boiler unless you are absolutely confident that you can do it correctly. If you are in any doubt, call a certified gas engineer who will be able to offer you safe, professional advice. Regular servicing will help to prevent many common boiler issues, and save you from the inconvenience of being without heating or hot water in colder weather.
