    What is a gas leak?

    A gas leak poses a grave danger, not to be underestimated, as it can result in severe health risks for your family. The presence of a gas leak is typically detected by its distinct odor, as natural gas is intentionally scented for easier detection. When your boiler encounters issues preventing proper fuel combustion, it may produce and release carbon monoxide, a highly toxic gas known for its lethal effects and potential health complications.

    Carbon monoxide has no smell added to it. It is also colourless. In order to detect a carbon monoxide leak, an alarm system should be placed near your system.

    What are some of the most common boiler repairs? 

    Boiler leaking

    A leaking boiler or central heating system, regardless of its size, demands immediate attention due to its severity. It’s advisable to shut off both the water supply and the boiler upon detecting a leak to prevent further damage.

    A malfunctioning component typically triggers boiler leaks, necessitating repair by a Gas Safe registered engineer. Common culprits include worn pressure valves or pump seals, which may require replacement. Additionally, pipe corrosion or improper installation can contribute to system leaks.

    Excessive boiler pressure is another potential cause of leaks. When adjusting your boiler’s water pressure, ensure it remains within the manufacturer’s specified limits to prevent leaks.

    No hot water or heating

    We know how annoying and upsetting it is to be left without hot water in the midst of winter. Several factors and reasons can cause this problem. To name a few:

    • Power to the boiler is off
    • Gas is not being supplied to your property or that the oil storage tank is empty
    • Boiler pressure is too low.
    • The condensate pipe may be frozen due to freezing weather conditions

    Check the pilot light on your boiler to see if it is on or not if you have an old boiler. Without a pilot light, you will be left without hot water and heating. A pilot light is an indication of the status of your boiler. It lights a larger flame when there is a need for hot water or heating.

    Cold radiators

    Encountering cold patches on radiators is a common issue, fortunately, easily resolved. When central heating is activated, hot water circulates throughout the radiators. However, air accumulation within the system can occasionally obstruct proper circulation, leading to incomplete heating and cold patches on the radiators.
