Top 8 Most Common Boiler Problems

Welcome. Hope you’ve been having a great time with yourself, family, friends and boiler? Yes, boiler—we know how important your boiler is to your everyday life.

What you should know about boilers is that no matter how good they may be, at some point, they will begin to develop some mechanical or electrical faults.

So, we have put together a list of some common boiler problems you can experience plus simple measures you can take to fix them on your own before reaching out to a more experienced boiler service provider.

Here we go.

This shouldn’t happen to you, especially in winter. But what if it does? No problem at all. All you need to know is that your boiler can turn off due to a frozen condensated pipe, the air in the system, low water pressure, a faulty thermostat or a faulty pump.

A simple measure you can take could be to thaw your condensate pipe (if that’s the issue) or bleed your radiators to remove air in the system.

If you can’t do any of these, call Plumbers in islington, and it’s done.

  • Noisy Boiler or Central Heating

Have you been hearing a rumbling noise which sounds like a kettle boiling? That’s what is known as kettling. It happens when limescale builds up and restricts the flow of water in the heat exchanger. The effect of this is that the boiler works harder to heat your water; this will shorten its lifespan.

Another cause of this noise could be air in the system. But you can power flush your pipes or bleed your radiator to remove lime scale and air.

The failure of the pumps can be a factor too. If you try and the problem persists, you can get a 24 hour emergency boiler repair immediately.

  • Faulty Thermostat

Your boiler can go bad with a faulty thermostat, especially when it’s a little old. So, if your thermostat is no longer accurate or doesn’t turn the heating on and off the way it should, then it’s time to get it changed.

But you can do a simple check on the thermostat to see if it’s in the on position and the schedule and time settings are correct.

  • No Heat or Hot Water

This can be caused by broken diaphragms and airlocks, a faulty thermostat, low water levels, or failure of motorised valves. Any of these can be replaced to restore heat or hot water in your boiler.

  • No Heat in the Radiators

The absence of heat in the radiators can be experienced when:

  • The radiators are heating up at the bottom
  • There’s no heat at all
  • Sludge builds up

You can try bleeding or power flushing in the first case. You could also adjust the valves of your radiators—a method called balancing in the second case. But the third case certainly requires professional help.

  • Pilot Light Keeps Turning Off

The pilot light on your boiler may turn off due to a faulty thermocouple cutting off the gas supply, damaged seals, deposit build-up, or a draught blowing out the pilot light. Check to see if there is a problem with your gas supply. For example, if the gas stopcock is on, but the gas is not getting to the boiler. If none of your other gas appliances is working, you should call your gas supplier. Gas is dangerous, so if you can’t try relighting the pilot light yourself, please call local plumbers in Islington to get a Gas Safe registered plumber.

  • Loss of Boiler Pressure

A water leak or expansion vessel can cause your boiler to lose pressure. You can try re-pressurising your boiler by following the instructions on the manual. But it’s better to leave it for the experienced plumber.

  • Frozen Condensate Pipe

A condensate pipe removes acidic water from the boiler and takes it outside into a drain. If it becomes frozen, you can try thawing it by pouring warm water into the pipe.

You can be confident enough to resolve some of these boiler issues yourself but if the problem is complex, feel free to contact our emergency plumber today.
