In radiant wall and ceiling hydronic room heating or cooling systems, using tubing that is fed hot or cold water, the tubing is embedded in gypsum or cement wallboard in intimate thermal contact therewith so that the wallboard heats or cools the room

Abstract

A method of providing hydronic radiant heating and/or cooling to a room that is framed by wall studs and ceiling rafters, comprising the steps of: providing a sheet of gypsum or cement wallboard with a length of tubing embedded in said gypsum or cement material of said wallboard, attaching the sheet of gypsum or cement wallboard with length of tubing embedded therein to the wall studs or ceiling rafters of the room, abutting conventional wallboard of the same thickness and connecting a supply of warm or cool water to the tubing for feeding water through the tubing, so that heated water so fed through the tubing heats the gypsum or cement material in the wallboard, which heats the room, or cooled water so fed through the tubing cools the gypsum or cement material in the wallboard, which cools the room.

1 . A hydronic radiant heating and/or cooling system having a heating/cooling loop including a length of tubing that conducts water, mounted in a wall or ceiling of a room heated/cooled by said system so that the room is heated/cooled by conduction of heat between the water in the tubing and the room, the improvement comprising, 
 (a) a sheet of gypsum or cement wallboard,    (b) a length of tubing embedded in said gypsum or cement wallboard,    (c) said sheet of gypsum or cement wallboard with length of tubing embedded therein attached to the wall studs or ceiling rafters of said room, abutting conventional wallboard of the same thickness and    (d) means connected to said length of tubing for feeding water through said tubing,    (e) whereby, heated water so fed through said tubing heats said gypsum or cement material in said wallboard, which heats said room and    (f) cooled water so fed through said tubing cools said gypsum or cement material in said wallboard, which cools said room.    
     
     
         2 . A hydronic radiant heating and/or cooling system as in  claim 1 , wherein, 
 (a) said gypsum or cement material in said wallboard acts as a temperature sink for heating or cooling said room    
     
     
         3 . A hydronic radiant heating and/or cooling system as in  claim 1 , wherein, 
 (a) said wallboard sheet is sized for conventional attachment to wall studs or ceiling rafters alongside conventional wallboard and for finishing like conventional wallboard.    
     
     
         4 . A hydronic radiant heating and/or cooling system as in  claim 1 , wherein, 
 (a) said sheet of wallboard has an inside face and an outside face and grooves in one of said faces thereof and    (b) said length of tubing is embedded in said grooves.    
     
     
         5 . A hydronic radiant heating and/or cooling system as in  claim 4 , wherein, 
 (a) said grooves are in said outside face    
     
     
         6 . A hydronic radiant heating and/or cooling system as in  claim 4 , wherein, 
 (a) said grooves are in said inside face    
     
     
         7 . A method of providing hydronic radiant heating and/or cooling to a room that is framed by wall studs and ceiling rafters, comprising the steps of: 
 (a) providing a sheet of gypsum or cement wallboard,    (b) providing a length of tubing embedded in said gypsum or cement wallboard,    (c) attaching said sheet of gypsum or cement wallboard with length of tubing embedded therein to said wall studs or ceiling rafters of said room, abutting conventional wallboard of the same thickness and    (d) connecting a supply of water to said length of tubing for feeding water through said tubing,    (e) whereby, heated water so fed through said tubing heats said gypsum or cement material in said wallboard, which heats said room and    (f) cooled water so fed through said tubing cools said gypsum or cement material in said wallboard, which cools said room.    
     
     
         8 . A hydronic radiant heating and/or cooling system having a heating/cooling loop including a length of tubing that conducts water, mounted in a wall or ceiling of a room heated/cooled by said system so that the room is heated/cooled by conduction of heat between the water in the tubing and the room, the improvement comprising, 
 (a) a sheet of paper encased gypsum or cement wallboard that has grooves recessed in the outside face thereof, all entirely encased in said paper, said paper being specially adapted for the adherence thereto of hard plaster applied thereto as a skim coat,    (b) said sheet of wallboard attached to the wall studs or ceiling rafters of said room, abutting the like or conventional wallboard of the same thickness,    (c) a length of tubing inserted in said wallboard grooves,    (d) A skim coat of hard plaster covering the outside face of said wallboards including said inserted tubing,    (e) means connected to said length of tubing for feeding water through said tubing,    (f) whereby, heated water so fed through said tubing heats said wallboard, which heats said room and    (g) cooled water so fed through said tubing cools said wallboard, which cools said room.    
     
     
         9 . A hydronic radiant heating and/or cooling system as in  claim 8 , wherein, 
 (a) said gypsum or cement material in said wallboard acts as a temperature sink for heating or cooling said room.    
     
     
         10 . A hydronic radiant heating and/or cooling system as in  claim 8 , wherein, 
 (a) said hard plaster coat raises the radiation efficiency of the heated or cooled wallboard.    
     
     
         11 . A hydronic radiant heating and/or cooling system as in  claim 8 , wherein, 
 (a) said wallboard sheet is sized for conventional attachment to wall studs or ceiling rafters alongside conventional wallboard and for finishing like conventional wallboard.    
     
     
         12 . A method of providing hydronic radiant heating and/or cooling to a room that is framed by wall studs and ceiling rafters, comprising the steps of: 
 (a) providing a sheet of paper encased gypsum or cement wallboard that has grooves recessed in the outside face thereof, all entirely encased in said paper, said paper being specially adapted for the adherence thereto of hard plaster applied thereto as a skim coat,    (b) attaching said sheet of wallboard to the wall studs or ceiling rafters of said room, abutting the like or conventional wallboard of the same thickness,    (c) inserting a length of tubing in said wallboard grooves,    (d) applying a skim coat of hard plaster covering the outside face of said wallboards including said inserted tubing,    (e) connecting said length of tubing to means for feeding water therethrough,    (f) whereby, heated water so fed therethrough heats said wallboard, which heats said room and    (g) cooled water so fed therethrough cools said wallboard, which cools said room.
