Abstract:
An apparatus for attaching a thermally conductive metal plate or sheet to flat surfaces of wood holders in a process of fabricating modular unit radiation panels for mounting in a floor or a wall of a room of a building heated by a hydronic heating system that pumps hot water through tubing that is held by said modular units for RFH or RWH, respectively, wherein said modular unit is an assembly of said thermally conductive metal plate or sheet having length, width and thickness and said wood holders are flat wood boards that provide a slot in which said tubing is inserted and held against said metal plate or sheet, comprising:a tool having a base, a point, a front face, a rear face, two sides and two point sides extending from said base to said point,wherein said point defines a cutting edge extending from said front face to said rear face, andthe length of said point edge is greater than the width of said point sides at said base,whereby said tool point thrust into said modular unit through said metal plate or sheet into one of said holders makes a hole in said holder and cuts a tab of said metal that is embedded into said hole,the free end of said tab being wider than the end thereof attached to said metal plate or sheet, andsaid free end of said tab being wider than said hole in said holder at said holder surface at said attached end of said tab.
