No matter how long you've been turning to your local HVAC contractor for maintenance and repairs, you may not know exactly how the boiler works. With warmer months ahead, now is an excellent time to dive into the inner workings of this system before it gets back to work again later this year.

How the Heating Begins

Once you flip an electric switch, a valve will open and let a steady supply of natural gas into the boiler's sealed combustion chamber. After that, the electric ignition system kicks in and jets of lit gas contact a heat exchanger. This component is connected to a cold water pipe, which transfers the heat, so the water temperature can rise to the desired level.

Delivering Warmth Throughout the Home

A continuous circuit of piping takes the heated water around the home, passing through the radiators before making its way back to the boiler. Since the water eventually cools again as it travels through the house, the boiler steadily fires while an electric pump keeps the circuit running. A thermostat maintains the best level of heat for you and switches the boiler off and on, depending on whether the set temperature has been reached.

With the amount of work a boiler does, it’s essential to have an HVAC contractor provide regular maintenance. A professional can clean the combustion chamber, replace the filter, test the system's efficiency, and inspect the flue pipe for holes or corrosion.
