Now that the harsh cold winter has arrived, it is time to check your heating system, and this means the boiler. Whether you are in an office building, school, hospital, or manufacturing facility, you’ll be depending on a commercial boiler. If you are toying around with the idea of getting one, read below to know more.

The basics of commercial boilers

Commercial boilers are pressurized systems. They use either electricity or combustible fuel for heating the water in one or more large tanks. Once done, they distribute the heat through air ducts, water pipes or steam. Note that natural gas is the most commonly used fuel. In some cases, the boiler heats water or steam and this is passed through radiators. The result? You now have comfortable and ventilated indoor spaces.

Commercial boilers typically contain the following:

Burner: It is the crucial part that provides flames to heat the water in the boiler. The primary task of the burner is to create a mixture of fuel with oxygen that produces a consistent and efficient burning flame.
Combustion chamber: It is the area within the boiler where the fuel gets burned. It is where the burner resides. It is designed for the high-temperature combustion of volatile gases. For this reason, it is made of cast iron, steel or other heavy-duty metal.
Heat exchanger: This transfers the heat produced by the burners to the water inside the boiler. This component is vital and usually made of cast iron, copper or steel tubes.
Controls: Using these, you can set the water temperature, the ignition, and the air and fuel supply mixtures. Also, internal pressure is now under your control.
Exhaust stack: Alternately known as the flue, the exhaust stack consists of one or more pipes for carrying the exhaust gases to the outside.

Even heat distribution

Commercial boilers work efficiently to distribute heat evenly across the premises. They are made to run for extended periods. The system works because water conducts thermal energy quickly and retains heat longer than air. This saves you money.


Commercial boilers are often used along with cooling towers and chiller systems for heating purposes. They are popular in the food, hospitality, and healthcare systems.
