Water is heated in either a cast iron or steel boiler before it is dispersed throughout your home. In a hot water system, the heated water is circulated through radiators or baseboards. In a steam system, the water turns to steam and rises through pipes to the radiators. In a warm air system, your furnace heats air. A blower then sends the heated air up through the ducts and out of vents in your floors or walls. The air gets drawn back to the furnace through a return duct and the cycle repeats.
