    In-floor heating uses hydronic piping (floor heat) embedded in or below the floor to provide heat (Figure 3). Heat is provided from a boiler or ground source heat pump (geothermal). These systems often are preferred because the heated floor provides a warm surface to stand on and water on the floor dries rapidly. Figure 1. Forced-air propane Learn More
