Since the time of the Roman Empire, radiant systems have been used to deliver heat to buildings. One of the more recent modern examples involves Frank Lloyd Wright, who incorporated hydronic radiant heat into his designs in the 1930s. With the development of advanced materials in the 1960s-specifically PEX, or cross-linked polyethylene-this comfortable, efficient and effective source of heat has become extremely reliable, durable, safe and readily available.
