How Does a Boiler Work?
You might understand that a boiler utilizes water to heat your home, but it's actually a complex process that uses certain chemical characteristics in order to provide the utmost heating efficiency. The boiler starts by heating up the tank of water that sits inside of it; and while the boiler can provide a unique way of heating your home, it’s not uncommon for a small gas or electric furnace to do the water heating for your boiler. This heated water starts to create hot steam within the tank, which is then funneled out of the tank and into pipes and ducts within your home central heating system. This residual heat warms up the air within your home making it more comfortable and enjoyable.
This process is also highly efficient for a few reasons. Air does not hold heat very well, and water is much more difficult to move, so steam provides a happy medium for transferring heat throughout your home without losing energy. Another feature of efficiency is that oftentimes, the steam is circulating within a closed loop, so the water that was heating your home is sent back to the boiler to be recycled, giving you the most efficient process of utilizing resources and energy to heat your home.
