Warning Signs To Look Out For With Your Gas Appliances

10 September 2024

Gas has been widely used in commercial settings for decades, where it can provide a cheaper and more versatile energy source than electric alternatives. As such, gas power can be relied upon to run a range of appliances and installations, including boilers, heaters and refrigeration systems.

Importantly however, gas appliances should only be installed and handled by a fully qualified gas engineer. You should also carry out regular maintenance checks and ensure that your appliances are being used correctly. This is because gas appliances can be dangerous if they are mishandled, where you could be exposing yourself to leaks or explosions.

As such, it is essential to keep an eye on your gas instruments, so you can make sure everything is working correctly. Read on for a look at some of the key warning signs that something is amiss with your gas appliances.

Flame Changes

If you’re using a gas stove or cooker, then changes to the flame colour could indicate that something is amiss. Equally, if you’re unable to control the temperature as easily as you’d like then there may be a problem with your appliance. For boilers, you will know that there is an issue if the pilot light flame keeps extinguishing or flickering out.

Unusual Smells

Another key indicator that there is a problem with your appliances is if you start to smell gas. This is usually sulphuric in nature, where a serious leak should be detected by your carbon monoxide alarm. If you do detect a gas smell, then you should endeavour to ventilate the space and notify your gas supplier immediately, where they may encourage you to evacuate the building.

Noticeable Marks

Some gas appliances will leave marks on surrounding surfaces if there is an issue. For instance, black or brown areas could indicate that there is a leak or a fault with an internal mechanism. Soot deposits could also mean that incomplete combustion has taken place, where this should be inspected immediately by a gas engineer.

Loud Noises

If your appliances are making loud or unusual noises, then this could mean that there is a serious fault. Whistling, banging or vibrations coming from your boiler should be checked out by a professional, where this may indicate that there is an air blockage or that your system is overheating.

Emergency vs Routine Plumbing Repairs: When to Call the Experts

19 November 2025

When it comes to plumbing issues, timing is everything. A small leak can quickly turn into a major problem if left unchecked, while some situations demand immediate attention to prevent costly damage or business disruption. Understanding the difference between emergency and routine plumbing repairs can save you time, stress, and money, and help you know when it’s time to call in the experts. What Counts as a Plumbing Emergency? A plumbing emergency is any issue that poses an immediate risk to safety, property, or business operations. In commercial environments, even a short period of downtime can have serious consequences, so swift action is essential. Common plumbing issues include: Burst or leaking pipes – Sudden water leaks can cause flooding and damage walls, floors, and electrical systems. Blocked or overflowing drains - Particularly in high-traffic areas, this can create health hazards and disrupt operations. No hot water or heating - Especially critical in settings like schools, hospitals, or care facilities. In these situations, it’s vital to contact a qualified plumbing engineer right away. Our team at Caledonian Heating & Plumbing provides rapid-response emergency support to restore safety and minimise downtime for commercial clients. When Is It a Routine Repair? Routine plumbing repairs cover non-urgent maintenance tasks or issues that develop gradually. While they might not cause immediate disruption, they still need attention to prevent bigger problems later on. Examples of routine repairs include: Slow-draining sinks or toilets Minor leaks under basins or radiators Reduced water pressure Regular maintenance of heating systems or water tanks Scheduling routine repairs ensures your systems continue running efficiently and helps you plan maintenance at a time that suits your business, avoiding the cost and chaos of unexpected emergencies. The Benefits of Preventative Maintenance Many plumbing emergencies are avoidable with regular inspections and servicing. Planned maintenance helps identify potential issues before they escalate, ensuring your systems remain compliant, efficient, and reliable. At Caledonian Heating & Plumbing, we tailor maintenance schedules for each client, from small businesses to large facilities, to keep everything flowing smoothly year-round.
