Causes

The main causes of boilers breaking down are limescale build-up, corrosion, low water pressure, thermostat faults and sludge accumulation. In areas with hard water, it is usually limescale which causes an issue, as it leads to chalky deposits which restrict water flow. Corrosion leads to weakening of metal components which eventually cause leaks. A faulty thermostat means your boiler doesn’t respond to temperature demands correctly.

What to do when the boiler fails

In the first instance, check your troubleshooting guide, as it may be a simple issue which you can solve yourself. However, if you smell gas or spot a leak, turn the boiler off and contact a registered engineer immediately.
