What is a Boiler?

In the simplest terms, a boiler is a sealed pressure chamber. Inside it, fuel is combusted in order to heat water. That heated water is then used to provide heat in commercial and residential heating systems. Water is an excellent medium for transferring heat through heating systems because it retains heat for a long period. For this reason, boilers are much more efficient than forced-air heating systems and furnaces.

How Does a Boiler Work?

In order for a boiler to heat water, combustion must take place. The most common boiler combustion systems burn natural gas to generate heat, but other fuels (oil, LPG, electricity) can be used depending on the boiler. Typical boiler combustion temperatures hover around 2200°F. The exact water temperature that the boiler will achieve depends on the type of boiler.

Difference Between Hot Water Boilers and Steam Boilers

Hot water boilers and steam boilers are the two main types of boilers. Both heat water for use in heating systems, but the way they go about this is a bit different.

In a hot water boiler, the goal is to raise the water temperature to a level just under its boiling point. In hot water boiler systems, the water itself is then pumped through the heating system to provide radiant heat.

In a steam boiler, the goal is to actually boil the water and create steam. The hot steam is then used in the heating system to provide radiant heat. In general, steam boilers require more energy to create steam but use less energy to circulate the steam through the system.

Find out which boiler is right for your application.

How Does a Boiler Heat Water?

There are two main designs found in today’s commercial boilers: firetube and watertube. This refers to the design of the boiler’s internal heating elements.
In a firetube boiler, combustion takes place inside tubes within the boiler. The tubes run through a large water tank and are completely surrounded by water. Heat is transferred into the water through the walls of the tubes.

Firetube boilers are generally less expensive because they are simpler in design and easier to produce, but they are limited to low and medium pressure applications.

Watertube boilers have a similar yet opposite design. In these boilers, tubes filled with water run through a large combustion chamber. This design offers high thermal efficiency, but can be more costly. Water quality can also have an impact on watertube boiler performance and water filtering may be required in the feedwater system.

Regular maintenance and service can extend the life of your boiler.

Why regular maintenance and service for your boiler is important?

The graph below shows 3 scenarios of a boiler in various stages of maintenance. Curved lines represent the boiler’s remaining life depending on the service performed. As you can see, our complete lifecycle advantage can extend the life of your boiler over 4x!

Boiler Lifecycle Preventive Maintenance Scenarios

ICA Boiler Burner Service Repair Maintenance

Scenario 1 – Complete Neglect

Boiler is installed, never started up properly, and no annual preventive maintenance is ever performed.

Life Expectancy: 5 Years

Scenario 2 – Inconsistent Maintenance

The boiler is installed and started up properly. However, preventive maintenance is not prioritized after the first 5 years.

Life Expectancy: 10 Years

Scenario 3 – Routine Maintenance

The boiler is installed and started up properly. Preventive maintenance is a priority every single year.

Life Expectancy: 20 Years
