How Does a Boiler Work? A New York Tech Explains Ranshaw

But the primary purpose of all boilers is to transfer heat to water. Basically, boilers work by heating water or producing steam that is then used to heat a home. But, of course, thats a barebones explanation of how boilers work. The inner workings of a boiler gets more complicated once you start looking at the different kinds of boilers.
