Bob's Tip of the Day: Furnaces heat air. If your heating appliance heats water, then it’s a boiler. If your appliance sources heat from the air, the ground, or a water reserve, then it’s one of several types of heat pumps. If there are ducts through which warm air blows, then you have forced-air distribution. If you have baseboard radiators, your distribution system is hydronic (hot water). If the heat comes from your floors (or walls or ceiling), you use radiant heat distribution.
What If Your Residential Heating System Ran On Compost? What if you could heat your house all winter for free, heat your household water for free, and cook with free gas most of the year? Sound to good to be true? Well, it’s not! And you can get almost everything you need to complete this project for free or next to nothing. Build your own residential heat5ing system in just a few days.
