The Difference Between Boilers And Water Heaters

Then, once the steam cools, it turns back to water, and moves back to the boiler. Because it is already warm, the boiler doesn't have to use much energy to get it back into steam and send it on the journey once again. What is the difference between the two? A boiler is used to heat a home using steam and radiant heat techniques.
