  • Radiant heating systems which are more efficient to build, and methods and apparatuses for building them
    Patent number: 5577554
    Abstract: A radiant heating system uses a conductive heat shield comprising a flat portion designed to be placed in contact with the underside of a floor and an elongated tube holding portion extending from the opposite side of the heat shield. Preferably the tube holding portion has an elongated opening for receiving tubing after the floor-contacting portion has been placed in contact with the underside of a floor, and has resilient restraining portions to hold the tubing in place once it has been inserted into that opening. It is also preferred that the tube holding portion be at least three quarters of an inch below the underside of any floor to which the flat portion is attached or is covered with a puncture-proof nail guard, so tubing in the tube holding portion will not be punctured by nails driven into the floor to which the heat shield is attached.
