How to Adjust Steam Heat | Hunker

Steam heat is a simple way of heating your home. A boiler heats water, turning it into steam. The steam is sent through the pipes to the radiators in your home. The steam heats up the metal of the radiator which in turn heats up the surrounding air. The steam cools down and condenses back into water and returns to the radiator through the same
