How Often Should Commercial Boilers Be Serviced

How often should commercial boilers be serviced? We look at the signs that your boiler need servicing. Find out what is included in a commercial boiler service.

How Often Should Commercial Boilers Be Serviced?

Around the entire globe, the UK is the third biggest market for boilers. In the year 2016, the UK accounted for 1.7 million units of sales. The country has current 26 million boilers installed and in use. Almost all of these units are gas condensing types.

Just because of the boiler's wide use doesn't mean that everyone is looking after their boilers in the best way possible. If a boiler broke down in the middle of an active workday, then it would not only be incredibly inconvenient but also a huge safety hazard to both customers and employees.

It would in all likelihood completely compromise the company's operations for the day. Affecting both reputation and revenue.

The best way to ensure that your boiler functions without issues or disruptions are to schedule and follow through with regular commercial boiler maintenance.

What Is Commercial Boiler Servicing?

Any boiler unit that has a 70kW power rating or above is classified as a commercial boiler. Due to this, regular servicing is necessary to ensure that the boiler is working at its most efficient and effective.

Commercial boiler servicing is, above all, a service to give you peace of mind. It is for you to know that your boiler is safe and is going to operate properly for the foreseeable future.

Boiler servicing will also check that the boiler's seals, gaskets, and heat exchangers don't show any kind of damage.

Why is Boiler Servicing Important?

Whether the boiler you have installed is a brand new state of the art unit or simply an old reliable installation then it is still of the utmost importance to have your boiler go through preventative maintenance regularly.

Boilers are not cheap and represent a significant investment, so it makes sense that anyone would want to ensure that their purchase lasts as long as possible.

The best way to do this is by having your boiler serviced on a regular basis. A commercial heating installation that may have just stopped working in a few weeks time can be given several years extra life just by having the unit looked at by a professional Gas Safe engineer.

Boilers that have been poorly maintained can not only drain your wallet but can also be a huge safety hazard to everybody who is around them. In a commercial environment, this can mean not only your employees but your customers too. Boilers are highly dangerous, disruptive, and unsafe for people when they have not been maintained.

Taking a proactive approach to boiler maintenance is beneficial in a number of ways. From a safety angle, a damaged boiler can result in a gas leak or poor ventilation. These can cause serious health hazards in the workplace and can even be fatal. Carbon monoxide poisoning can result in around fifty deaths per year in the UK.

Regular maintenance means that any issue, even minor issues, will be identified earlier and reported. This is a much better method than waiting for when the issues appear and it is far too late, or in the worst-case scenario when the boiler is needed.

For example, you wouldn't want your boiler to suddenly stop working in the middle of winter. It also means that any parts which may be damaged or need replacing can be identified.

Proactive maintenance is a lot cheaper than paying for repairs when the strike. An efficient boiler will also save you a lot of money. Efficient boilers minimise fuel wastage which will reduce your monthly fuel costs.

What Is The Recommended Frequency For Boiler Servicing?

The average lifespan of a commercial boiler is somewhere between 10 to 15 years. For most owners though, their boilers are taken for granted, especially when they are working as advertised. The majority of boilers should be serviced at least once every year.

Commercial boilers are extremely susceptible to regular wear and tear, due to their regular use. Commercial boilers will never just completely break down out of nowhere. They will always show the warning signs first. Instead of waiting for the symptoms to show themselves, act proactively and schedule regular maintenance.

What Is Included In A Commercial Boiler Service?

Firstly, the plumber will check to see if your boiler, pipework, and flue are all installed correctly. This includes all internal and external components. Any signs of corrosion, correct ventilation, the flame within the boiler, and leaks will also be checked.

Commercial boilers will be checked against current existing regulations which cover non-domestic establishments. This includes regulations that involve building laws, gas safety regulations, water by-laws, British standards, and other similar rulings.

Next, the boiler's casing will be removed. This is done to take a closer look at each of the internal components.

Some of the parts that will require attention will be the burner, main injector, heat exchanger, flue and combustion, gas pressure and flow, fans, seals, spark probe, electrical connections, safety devices, electrodes, condensate trap and pipe.

After this process is done, the inside of the boiler will be cleaned in order to remove any blockages or debris.

The third step in the process is a performance test. This is done to ensure that your boiler works in accordance with The Gas Safety (Installation and Use) Regulations 1998. If at this point any faults are discovered, for example a gas leak, then the plumber will make note of it and include the faults in the final boiler report.

When the examination process is over, the plumber will provide you with an extensive report of the process they have conducted. Any notable issues will be included in the report, especially if they involve a repair or replacement process. At this stage, you will also be told if your boiler is in violation of any building regulations or gas safety regulations. If you have any questions about your boiler or the maintenance process then now is the time to ask.

What Are The Signs That Your Boiler Need Servicing?

If your property is remaining cold while the boiler is still switched on, then this can be a potential boiler issue. In this situation, the first thing you need to do is check the radiators and pipes to see if they are heating up at the same time and to the same temperature. If your radiators are working as normal, then it is your boiler that is the issue.

If you have been hearing any strange or previously unheard noises from your boiler, then this should not be ignored. These noises can include hissing, clunking, ticking, and whirring. A busy commercial environment can drown out these noises but do pay attention as they are a common early warning sign that something is wrong with a boiler.
