How Does a Boiler Work?

The name “boiler” is a bit misleading—or at least it is today. The earliest boilers did indeed boil water and use steam to heat homes and businesses, but few boilers now rely on steam. They instead heat water, but the term “heater” already has the general meaning of referring to all heating systems. So the word “boiler” has remained… and so have boilers. They have stayed popular in homes for well over a century because of their low initial cost and longevity.

You now know a boiler doesn’t use steam—or at least the one that warms you probably doesn’t—but how does a boiler actually work? In this post we’ll look at the operation of the most common type of boiler, the natural gas-powered boiler. (Boilers can also run on electricity and, less commonly, oil.) If you need help selecting a boiler for your Pickering home, or need other Pickering heating services, contact Advantage Airtech. We have been in business since 1987 and have extensive experience with boilers.

Better Understand Boilers Before Installing One in Your Pickering Home

Boilers—regardless of their fuel source—operate on the same principle: the circulation of heated water toward terminal points where the heat then radiates into the house. Radiators and baseboards are the most common end points for the heated water. This water runs in a fixed cycle, and once cooled down, it returns to the boiler’s tank to begin the process.

The tank is where most of the work in a boiler occurs. A pilot light ignites gas jets in a combustion chamber located underneath the tank. These jets transfer the heat into the water in the tank, raising it to the temperature needed to supply the heat set on the thermostat. The heated water moves through a pump at the top of the water tank, which then sends the water on its way to radiate its heat into a home. An expansion tank above the boiler tank absorbs a build-up of pressure to prevent the boiler pressure from rising too high.

Because this operation requires few moving parts, boilers do not wear down as fast as furnaces and can reach long lifespans that make them attractive heating options. Although gas power always carries some hazards, modern boilers rarely experience problems, and if you schedule regular boiler maintenance and trust repairs to professionals, a boiler should present you with few troubles through its many years of service.
