Hot water mat for floor heating and its installation method

Abstract

A heat radiating pipe ( 2 ) that is disposed in a hot water mat ( 1 ) is extended from the hot water mat ( 1 ) to provide an extended portion that is used as connecting pipes ( 2 a and 2 b ) to a heat source machine ( 11 ). The construction makes it possible to prevent a water leak as there is no connection therebetween, and reduces costs for parts and installation as no connection tool, such as a coupler, is used. Further, guide pieces ( 13 and 14 ) attached with cover members ( 17 ) are arranged at positions where the connecting pipes ( 2 a and 2 b ) are extended, and the connecting pipes ( 2 a and 2 b ) are disposed by using the guide pieces ( 13 and 14 ), so as to efficiently utilize heat radiated from the connecting pipes ( 2 a and 2 b ), and to prevent thermal loss.

What is claimed is: 
     
         1 . A hot water mat for floor heating, the hot water mat comprising:
 a mat body; and   a heat radiating pipe disposed in the mat body in a meandering manner, the heat radiating pipe including an extended portion forming a connecting pipe, whereby hot water sent from a heat source machine circulates through the heat radiating pipe, and returns via a hot water loop-back to the heat source machine again, wherein an inlet and an outlet of the hot water of the heat radiating pipe extend from the mat body to an outer side of the mat body, and the extended portion of the heat radiating pipe is used as the connecting pipe passing through a room and being connected to the heat source machine that is outside the room.   
     
     
         2 . The hot water mat for floor heating according to  claim 1 , further comprising:
 a guide piece to be used in a path directing the connecting pipe from the mat body to the outside of the room, the guide piece having a thickness that is approximately identical to a thickness of the mat body and the guide piece having a guide groove of a V-shape or U-shape cross section that is formed on a top surface so as to receive the connecting pipe; and   a cover member that is attached to cover an upper opening of the guide groove.   
     
     
         3 . The hot water mat for floor heating according to  claim 2 , wherein the guide groove of the guide piece has a diameter that is identical to or slightly larger than an outside diameter of the connecting pipe, and the guide groove is attached slidably along the connecting pipe when receiving the connecting pipe in the guide groove. 
     
     
         4 . The hot water mat for floor heating according to  claim 2 , wherein the guide piece is attached to the connecting pipe in a unit of one piece or a plurality of pieces. 
     
     
         5 . The hot water mat for floor heating according to  claim 3 , wherein the guide piece is attached to the connecting pipe in a unit of one piece or a plurality of pieces. 
     
     
         6 . The hot water mat for floor heating according to  claim 2 , wherein the guide piece is attached to the connecting pipe in advance or in a retrofitting manner. 
     
     
         7 . The hot water mat for floor heating according to  claim 3 , wherein the guide piece is attached to the connecting pipe in advance or in a retrofitting manner. 
     
     
         8 . The hot water mat for floor heating according to  claim 4 , wherein the guide piece is attached to the connecting pipe in advance or in a retrofitting manner. 
     
     
         9 . The hot water mat for floor heating according to  claim 5 , wherein the guide piece is attached to the connecting pipe in advance or in a retrofitting manner. 
     
     
         10 . The hot water mat for floor heating according to  claim 2 , wherein the guide groove of the guide piece comprises at least one of a straight line portion and a curved line portion with respect to a planar view. 
     
     
         11 . The hot water mat for floor heating according to  claim 2 , wherein the guide groove of the guide piece comprises at least one of a straight line portion and a curved line portion with respect to a planar view. 
     
     
         12 . The hot water mat for floor heating according to  claim 3 , wherein the guide groove of the guide piece comprises at least one of a straight line portion and a curved line portion with respect to a planar view. 
     
     
         13 . The hot water mat for floor heating according to  claim 4 , wherein the guide groove of the guide piece comprises at least one of a straight line portion and a curved line portion with respect to a planar view. 
     
     
         14 . The hot water mat for floor heating according to  claim 6 , wherein the guide groove of the guide piece comprises at least one of a straight line portion and a curved line portion with respect to a planar view. 
     
     
         15 . An installation method of a hot water mat for floor heating, the method comprising the steps of:
 providing a mat body;   providing a heat radiating pipe;   disposing the heat radiating pipe in the mat body in a meandering manner to form a hot water mat;   laying the hot water mat in a room; and   providing the heat radiating pipe with an extended portion forming a connecting pipe, whereby hot water sent from a heat source machine circulates through the heat radiating pipe, and returns via a hot water loop-back to the heat source machine again, wherein an inlet and an outlet of the hot water of the heat radiating pipe extend from the mat body to an outer side of the mat body, and the extended portion of the heat radiating pipe is used as the connecting pipe passing through a room and being connected to the heat source machine that is outside the room.   
     
     
         16 . The method according to  claim 15 , further comprising the step of:
 providing a guide piece in a path directing the connecting pipe from the mat body to the outside of the room, the guide piece having a thickness that is approximately identical to a thickness of the mat body and the guide piece having a guide groove of a V-shape or U-shape cross section that is formed on a top surface so as to receive the connecting pipe; and   providing a cover member that is attached to cover an upper opening of the guide groove.   
     
     
         17 . The method according to  claim 16 , wherein the guide groove of the guide piece has a diameter that is identical to or slightly larger than an outside diameter of the connecting pipe, and the guide groove is attached slidably along the connecting pipe when receiving the connecting pipe in the guide groove.
