Radiant floor heating may seem like a modern concept, however, this technique has existed for thousands of years. It was first used by the Romans, who built raised marble floors; using fire to heat them. The also constructed flues to control the flow of the heat underneath the floors. As a result, the rooms were much warmer. Another concept developed centuries later which involved pumping hot water through buried copper pipes. This concept had one major flaw, constant erosion and leaking of these copper pipes. Due to recent technological advances, radiant floor heating is more efficient. Homeowners can install a radiant floor heating system in any room, providing the ultimate convenience and versatility. This technique uses special mats equipped with flowing wires. The mats heat the floor above them, once the electricity is generated through them.
