Five Common Boiler Problems and How to Fix Them

We all take our boilers for granted, expecting them to keep our homes warm during the cold winter months and provide us with warm water as and when needed. However, when a boiler breaks down it can be an expensive inconvenience that requires professional help. Let’s explore some of the most common problems you’re likely to come across if your boiler decides to act up.

No Hot Water or Heat

The most common causes can include low water levels, thermostat issues, motorized valve failure or broken airlocks and diaphragms. The issue could be due to low pressure. According to British Gas, the pressure gauge should read above one bar. If this is not the case, then it could be due to a leak within the boiler or a pressure relief valve that needs replacing. Recently bled radiators can also lead to reduced boiler pressure.

Dripping and Leaking

This could be due to a number of reasons. You’ll have to locate the source of the leak to determine the cause. If the leak originates from the pressure valve, this may indicate that your boiler’s pressure is too high. If it comes from the pump seal, then it might be worn out and need replacing. Boilers that leak from the pipes or tank maybe suffering from corrosion.

Extinguished Pilot Light

his could be due to a broken thermocouple leading to a stop in the gas supply, a gust of air which has blown out the pilot light or a build-up of deposit in the pilot light. Make sure there are no issues with the gas supply before you try to reignite the pilot light. If you are unable to light it, then maybe it’s best to call out a professional such as http://www.hprservicesltd.com, who carry out boiler repair in Cheltenham and the surrounding region.

Thermostat

Ageing thermostats can lose accuracy and turn your boiler off when they shouldn’t. Ensure that the thermostat is in the correct position and that it is set to the right settings like schedule and time. If it still doesn’t work, then you’ll have to invest in a new one.

Kettling

Limescale can build up on the boiler’s heat exchange, restricting the movement of water. The water becomes overheated and boils, making it harder to run and more expensive to operate.
