Top 5 Commercial Gas Boiler Faults

Commercial boilers are made specifically to handle high demand; they generate a lot of energy to heat the water and move it around the system. Because a boiler relies on so many components operating together, a single failure can often lead to additional problems that you will be unable to resolve on your own. At this point, specialist assistance is required, so it’s time to contact boiler professionals that are knowledgeable about commercial boilers, whether they are for a hotel, restaurant, school, or hospital.

In this post, we’ll look at some of the most typical boiler problems that you can encounter in a business setting. Most of the time, the problems can be fixed quickly and inexpensively, but more significant problems might necessitate ordering and installing new parts as well as more examination.

Whistling Or Banging Noises

Commercial boilers should operate quietly and without noise unless they are heating water, at which point you might hear a tiny blowing sound coming from the burner. But, if your boiler is pounding, bubbling, or whistling, that could be a sign of something more catastrophic.

It can be the result of the low pressure or the minerals that the water in the system deposited that have led to limescale on the inside of the appliance. In either case, it must be checked to make sure it is secure for usage.

You Have Low System Pressure

There is probably a leak in the system if you’ve noted that the boiler pressure gauge is substantially lower than usual, which in most systems should be between 1-2. The pressure of the entire system might be impacted when steam is lost due to leaky pipes or poorly secured valves and seals.

If you feel this is the problem, get in touch with a commercial boiler repair firm so they can evaluate the situation. Another potential cause might be your feed pump not functioning properly or even the steam trap. They will be able to perform a series of tests to identify the issue and replace any necessary components.

The Boiler Is Leaking Water

A steady drop coming from the boiler, regardless of whether the water is filthy, rusty, or clean, suggests a problem inside the tank. This could be a result of internal pipework or component corrosion, or the leak may be brought on by damaged valves and seals.

Condensation may just be dripping from inside since it can’t be removed correctly, but in more serious situations, your expansion tank may be rusted and directly leaking water. Call a commercial boiler engineer for service and repair and position a huge bowl under it where you can observe the water dripping out.

Neither producing heat nor operating above a low temperature

When you turn on the faucets or turn on the shower, you can see that absolutely no heat is being transmitted. The water could be lukewarm, icy cold, or even at normal temperature. It can occasionally take a commercial boiler some time to deliver the hot water it produces, especially if the building has a lot of plumbing.

If nothing has changed after a minute, make sure the tap is turned to the hot setting, then turn it off since your boiler or pipes may be malfunctioning.

The problem could be that the buildup on your burners has caused them to get blocked, which prevents heat from being produced. Please refrain from attempting to clean this debris yourself since it poses a risk of fire.

This fault can also be caused by issues with the thermostat, the ignition, the pump, or even the thermostat itself. If you turn up your thermostat to the highest setting and your boiler still won’t start, have it looked at by a professional.

There is an uneven distribution of heat

If you notice that certain areas of your office building are chilly while others are warm, there may be a problem with the radiators or the plumbing. Make sure your boiler is off before you bleed any radiators that are filled with air. You need to do this slowly until water begins to flow out of the upper area of the radiator.

Once the air has been removed, turn the heating system back on, and the radiator should be warm throughout. This could be the explanation; your heating system may have controls in place to detect which zones require warmth. Carpeted areas should require less heating than those with bare wood or concrete floors.

Unless the boiler has been configured to heat zones to different degrees, the issue may not necessarily be with the boiler in this instance.

Is the operation of your boiler system malfunctioning? Contact Rowlen, the industry leader in commercial boiler servicing, and we’ll send a team to your location to look into the problem. Many of the defects we see can be fixed right away, but occasionally new parts must be ordered and fitted. We may always recommend new boilers for your precise needs if the problem cannot be fixed.
