Common Issues With Commercial Heating Systems

If you are working within a commercial facility, such as a hotel, retail outlet or care home, heating systems are essential. It is always important to ensure that your commercial boiler is functioning optimally and reliably, especially when you and your employees are working during the winter months. Whether it’s an office or a hotel, there’s no denying that commercial buildings can be tricky, and expensive, to heat. 

In order to help prevent costly repairs, it pays to know some common issues with your commercial heating system. Things can always go wrong and the team at Murdock Heating and have put together a list of some of the most common issues with commercial heating systems. 

Boiler Blockages

Hard water is one of the main reasons for pipe blockages, as this contains a high level of mineral content. The minerals in hard water will leave deposits in the pipe walls, and should these become thick enough, it can cause clogging to occur. 

Another common culprit for pipe clogs is rust, as this will start if too much oxygen gets mixed into the system. If this is the cause, repairs by a team of specialist commercial boiler engineers will be required to eliminate the clogs, but also to find out what has caused the rust to start.

Pressure drop

Every boiler needs to maintain pressure within a specified range in order to function correctly. One of the main causes of this drop in pressure is due to water leakage, which can be hard to identify due to the complex nature of modern plumbing. Corroded pipes and radiators can also be a good clue to where a leak may be located, as well as a damp floor, leaky pipes, or a small hole in a radiator somewhere. A damp floor, leaky pipes, or a small hole in a radiator somewhere. 

Boiler noise

A noisy boiler should never be ignored, but it is important to establish exactly where the noise is coming from. As these noises will normally not go away on their own, it is prudent to consult with an expert.

It could be a number of things, such as a noisy boiler, or a noisy radiator or central heating pipe, each of which can have different causes. For example, if the boiler is buzzing or whining, this could be a genuine cause for concern that is typically caused by worn pump bearings, a defective burner or vibrating fans. In this case, it would be best to speak to a qualified professional who would be able to fix the problem. 


The three issues we have mentioned are just a few of the common problems that businesses experience with their commercial heating systems. These can often be avoided by having regular boiler servicing, which will help keep it in good working condition. This will help to detect any potential problems with your boiler, preventing unwanted disturbances to your heating supply.
