It's time tested, and in my opinion, the best form of heating you can have. Radiant heat uses invisible electromagnetic infrared waves to heat you. It doesn't heat the air, as the system did in the house you grew up in. The objects that are in the direct pathway of the infrared rays absorb the energy immediately. Once they heat up, they radiate heat to other objects in the room. It's a fascinating way to transfer heat very efficiently. Radiant heat sources in a home can take many forms.
