How Do Commercial Boiler Systems Work?
Commercial boilers are sturdy and reliable pieces of heating equipment, supplying heating and hot water to very large commercial properties. However, many people are actually unaware of how they work.
In this guide, we’ll discuss how they work, the basic components and how they differ from domestic boilers.
What is the main difference in how a commercial and domestic boiler operates?
The main difference in how commercial and domestic boilers operate is how powerful they are. Although they both work in the same way, commercial boilers have increased duties in order to cope with being used in a busy commercial environment.
Domestic boilers usually have an output of 10-40kW, whereas commercial boilers tend to have an output of anywhere between 50-150kW in order to keep up with high demands in larger buildings for heating and hot water.

The basic components of commercial boilers
Listed below are the main components that you can expect to see on a commercial boiler system.
Burner
The burner is the part of the commercial boiler that mixes air with the fuel source and combusts. The hot combustion gases enter the boiler, which is used as a heat exchanger.
The right amount of combustion air is vital for clean and efficient combustion, which is why it is essential the burner is kept in good working condition.
Combustion chamber
The combustion chamber is where the fuel is burned to heat the water. The chamber is where the burner is located and is designed to be a very safe space for high-temperature combustion. It is usually made from durable materials such as steel or cast-iron.
Heat exchanger
The heat exchanger is the component that transfers heat produced by the burner to the water in the boiler. The heat exchanger is made up of several elements including bundles of steel tubes, cast iron and copper lines.
The elements are again made of strong and durable materials to withstand high temperatures and transfer the heat efficiently.
Heat exchanger
The controls on a commercial boiler allow the water temperature to be set to a specific temperature, as well as the internal pressure, ignition and air and fuel supply.
Without the right controls, high-pressure steam can be incredibly dangerous. Controls help to make sure your commercial boiler is safe by making sure that the internal pressure within doesn’t go too high and the water stays at a safe temperature.
Circulator pump
The circulator pump is what pushes the hot water through the supply lines to radiators and taps. It is also what brings the water back through the return lines.
The circulator pump plays an essential role in a commercial boiler, which is why it is essential that it is well maintained.
Exhaust stack
The exhaust stack, or commonly known as the flue, is designed to safely expel used fuel away from the building’s exterior.
The exhaust stack must be fitted safely and correctly so that dangerous gases, like carbon monoxide, are diverted away from the interior of your commercial environment.
How do commercial boilers work?
Commercial boilers work in the same way as domestic boilers, but just on a large scale.
The commercial boilers are pressurised systems that burn combustible fuel or electricity to heat water that is then distributed around the building for heating and hot water.
Some boilers will use the hot water itself, whereas others may use the steam itself if there is a very high demand for heating, such as in hospitals.
Maintenance of a commercial boiler system
Just like with a domestic boiler, commercial boilers require maintenance to ensure everything is in safe, working order. Boilers must be cleaned to prevent any breakdowns and therefore reduce downtime. They should also be checked for any leaks, as they can be extremely dangerous, causing injuries or damage to the property.
