This radiator is much like floor heating, but with the advantages of the large surface design of a radiator. The inside of the radiator is made with tubing you find in floor heating. Floor heating tubes have triple walls to prevent heat expansion. The outside is casted with glass fiber reenforced concrete. The unique baroque decoration of the radiator is applied to expand the surface. According to Joris' tests the radiator has better heat transmission capabilities than a normal steel radiator or floor heating.
