What Can Go Wrong With Your Commercial Gas Boiler?

Caledonian Heating • 30 January 2024

Commercial boilers are designed to provide both heating and hot water to large buildings, serving a similar function to boilers in domestic properties. This piece of equipment is incredibly important when it comes to creating workable conditions inside a commercial building, where appropriate temperatures and a hot water supply are essential for employee comfort and for everyday industrial processes.


As such, it is vital that your commercial boiler is well maintained and functional at all times. In order to achieve this, you need to be aware of all the things that can go wrong with your system, where having some knowledge of potential issues makes it easier to resolve small faults before you experience a major malfunction.


Read on to find out more about common problems that can arise with your boiler, with a look at the various causes of these faults.


Heating Issues

Heating issues are one of the most noticeable boiler problems that can quickly impact your building. Your system may only be emitting heat at low temperatures or your system’s heating capabilities may have failed entirely. This could indicate a superficial problem with your radiators, or you may be experiencing a more serious blockage inside your boiler system.


Leaks

Leaks also indicate a very visible problem with your boiler system, where this fault can cause damage to your boiler room and the surrounding areas. No matter the colour or consistency of your leak, a drip from your boiler typically indicates a problem with your tank. This may be caused by corroding pipes or a broken valve inside your boiler system.


Low Pressure

Low pressure is another common fault, where you will notice this is a problem if you see a change in your boiler pressure gauge. This can be caused by a leak in your boiler system, or if steam is being lost through unsecured valves and seals. Other causes of low pressure can include problems with your feed pump or steam trap.


Disruptive Noises

You may also notice that something is wrong with your boiler if you start to hear unusual noises emanating from your system, where these can include banging and whistling sounds. This can indicate low pressure issues or a limescale accumulation inside your boiler system, as well as potential breakages relating to your pipework.
