8 Common Boiler Faults and Issues

The average homeowner doesn’t really need to know what’s going on behind the cover of their boiler but they do need to maintain it to make sure that it’s running efficiently. Yearly boiler services can prevent problems from occurring, but like most appliances, small problems may happen throughout the life of your boiler. Here are the most common problems that we find at Glow Heating Services in Lincoln:

  1. No heating and no hot water

If you have no heating or hot water this could be due to a number of reasons including component failure, trapped air or low water levels, to mention a few. Here’s what you can do to identify the problem:

Check the pilot light in your boiler. It should be burning blue. Also, check your thermostat is set correctly; it might be set at the wrong time. Try resetting your boiler and restarting your central heating system.

  1. Boiler is leaking

A leaking boiler! Well, it’s obvious that your boiler should NOT be leaking. When this problem occurs within your boiler, you’ll need the assistance of a Gas Safe engineer as soon as possible as it could prove dangerous. Contact Glow Heating Services for a boiler repair in Lincoln. 

  1. Noises coming from the boiler

Your boiler will never be silent, but noises such as whistling and banging noises are something to take note of. Whistling and banging can be the sign of kettling, where limescale builds up in the boiler’s heat exchanger. It could also be due to trapped air within the system, causing low water pressure. This fault will cause your boiler to cycle on and off, meaning your boiler is working very inefficiently, costing you money. This boiler will need the assistance of a Gas Safe engineer, so contact us for fixed price boiler repair.

  1. Low boiler pressure

If your radiators aren’t heating properly it can sometimes be a cause of low pressure in your system. You can check your boiler’s pressure by identifying where the pressure gauge is marked at on your boiler. Dependent on the make and model of your boiler, it may turn itself off when the pressure drops below 0.7 bar. If your boiler is below 0.7 bar and repeatedly turning off then an engineer will need to find out why. Take a look at our helpful blog for guidance on checking the pressure of your boiler.

  1. Frozen condensate pipe

If it’s been particularly cold out and your heating has stopped working, your condensate pipe could be frozen. You can remedy this by applying hot water to the pipe, located outside your property. For more info read our blog on how to thaw a frozen condensate pipe. If this doesn’t solve the problem, then call us on 01522 300744.

  1. My pilot light has gone out

If your boiler is getting on in years, your pilot light may go out in high winds, so it may not need a repair, and as a homeowner, you are more than capable and allowed to re-establish your pilot light. It could also be a relatively easy fix for our engineers, as it could be the thermocouple that needs replacing. However, there is a possibility it could be something more serious such as damaged seals or a build-up of debris. 

New A-rated boilers don’t have pilot lights and provide top energy efficiency. According to Which? “If you replace an old G-rated boiler with a modern A-rated boiler with a full set of heating controls, the Energy Saving Trust estimates you’ll save around £340 a year on your gas bill.” That’s a huge saving. Read more about the Which? article here. If you have an old G-rated boiler it may be worth getting a free quotation for a new boiler. With a new appliance, you’re likely to make significant savings.

  1. Radiators not getting hot

Your radiators not getting hot can be due to a number of reasons such as a broken pump or a build of sludge in your pipes preventing hot water from circulating around the system. But before calling an engineer, look to bleed your radiators, as they may have excess air trapped in them. 

  1. Heating’s not coming on at its scheduled time

Your thermostat could be out of sync due to the clocks going backwards or forwards. Reset the thermostat by turning off your boiler and restarting your central heating system. Refer to your handbook for help. Did you know Hive (smart heating) automatically updates each time the clocks change? We install Hive Active Heating for £219. Contact us to find out more.
