When it comes to maintaining a target temperature, a traditional forced-air system leaves a lot to be desired. For one thing, by operating in a cyclical, stop-and-start pattern, forced-air heating makes temperature swings the norm. Second, there's the fact that warm air rises. So when furnace-heated air enters a room, it quickly flies up to the ceiling. Contrast that with in-floor heating, which concentrates warmth where you can actually feel it. By steadily transmitting thermal radiation (not warm air) into the space, in-floor panels provide even, "everywhere" warmth across the entire square footage of a space.
