What is a boiler and how does it work?

A boiler is water containing vessel which transfers heat from a fuel source (oil, gas, coal) into steam which is piped to a point where it can be used to run production equipment, to sterilize, provide heat, to steam-clean, etc. The energy given up by the steam is sufficient to convert it back into the form of water.

Is a boiler considered HVAC?

Boilers also heat water, but in addition to giving you hot water for all the purposes above, they provide warmth by circulating the hot water through your home using a series of pipes and baseboard radiators. … Because boilers are designed to provide heat (not just hot water), they fall into the HVAC category.
