How Does a Boiler Work?

Boilers were one of the first whole-home heating systems. Today’s boilers are very energy efficient, and can distribute heat through radiators, baseboard heating and radiant heating. How does the system work? We’ll detail more of that below, but what is important is having a reliable heating company to call whenever you experience problems with your heating. For over 20 years, Sound Heating has provided expert heating service in Tacoma and we can help you with any problems you may be experiencing with your boiler. Call us today!

How a Boiler Works

Boilers work by heating water and distributing the heated water, or the steam created from the hot water, through outlets like radiators.  Fuel, such as natural gas or oil, is ignited in a combustion chamber, and this flame heats the water in the system in one of two ways:

  • Firetube – enclosed metal tubes are submerged in the water tank and heated by fire or hot flue gases; this heat transfers to the water.
  • Watertube – instead of gases, water is inside the tubes, and the water is heated via combustion flames that surround the outside of the tubes.

With steam systems, the steam produced is kept in a dome on the top of the water vessel until it is released into the system for heating; the hot water releases when it hits the correct temperature. The water or steam circulates around the system, and when it cools, the cooled water returns to the boiler’s vessel for the next cycle of heating.

Benefits of Boilers

There are a few benefits of boilers worth considering:

  • Energy efficient – boilers have an average energy efficiency of 89% and can go higher than 95%
  • Comfortable heat – the heat coming from a hydronic system (system that uses water) is gradual as it radiates, which can feel more comfortable than forced air
  • No dust – boilers are closed systems, and as such, do not circulate dust the way a forced air system can, which can be very good for allergy sufferers

Boilers are efficient, durable systems, and can be a great choice for heating. If you are in need of a new heating system in Tacoma, call the people you can trust: Sound Heating.
