Hot water heater 10
The hot water mat 11 is arranged on a floor structure 20 as shown in FIG. 1, and is preferably arranged in a range of 50 to 80% of the floor area of the room to be heated.

Here, the floor structure on which the hot water mat 11 is installed will be described. The floor 21 is a floor of a so-called wooden building, and the joists 22 are arranged side by side at an interval L, and the interval L is usually 303 mm. Joist 22, 2
2, a heat insulating material 24 is arranged, and the thickness of the heat insulating material is set to be substantially the same as the thickness of the joist 22. Joist 2
2 is a plywood 26 called a so-called control panel.
Is arranged. The hot water mat 11 is arranged on the structural plywood 26.

The hot water mat 11 is disposed on the plywood 26, and a dummy plywood 28 is disposed in an area other than the hot water mat 11. The plywood 28 is a so-called dummy control panel.

The hot water mat 11 has a hot water pipe (heat transfer tube) 14 into which hot water as a heat medium is introduced, a mat 12 as a base material for holding the hot water pipe 14, and a small size for fixing a floor plate (flooring). Joists 16a, 16b,

Hot water pipe 14 for flowing hot water as a heat medium
A cross-linked polyethylene pipe, polypropylene pipe, polybutene pipe, or metal pipe is used. However, according to a resin material such as a flexible polyethylene pipe, the mat 12 can be rounded, which is convenient for transportation. The hot water pipe 14 has a substantially circular cross section, and the pipe diameter is, for example, 7.2 mm.
The buried groove 4 in which the hot water pipe 14 is held
1 (see FIG. 3) has a shape corresponding to the cross-sectional shape of the hot water pipe 14.

If the cross section of the hot water pipe 14 is elliptical, the contact area with the aluminum foil 18 as the heat transfer member can be increased, and the heat transfer efficiency can be improved accordingly.

The aluminum foil 18 is a covering means for covering the hot water pipe 14 and the mat 12, and also has a role of transmitting heat from the hot water pipe 14 or holding the heat. Therefore, as shown in FIG. 1, when the hot water pipe 14 is arranged on substantially the entire surface of the mat 12 and heat conduction to the entire surface is not performed, the aluminum foil 18 is provided only on a part of the front or back of the mat 12. You may. Further, the thickness of the aluminum foil 18 may be different. In addition, the aluminum foil 18 is preferably provided as shown in FIG.
As shown in the figure, a marking 18a is provided to indicate the positions of the small joists 16a and 16b.
It is formed corresponding to the lengths of a and 16b. The marking 18a is, for example, a green line having a width of 30 mm.

Therefore, in the lead-in / out area A, the temperature difference between the forward pipe 14a having a high hot water temperature and the return pipe 14b which has been radiated after the circulation and the hot water temperature has become low can be balanced by the heat transfer, The temperature unevenness between the adjacent outgoing pipe 14a and the incoming pipe 14b is reduced. Furthermore, the outgoing pipe 1
The hot water heat of 4a absorbs heat in the return pipe 14b, and the temperature unevenness of both pipes is reduced. As a result, as a whole, an extremely high temperature in the lead-in / out area A is prevented, and temperature unevenness in the lead-in / out area A and the circulation area B is also reduced. In particular, in each of the regions A, C, D, and E, the forward pipe 14a and the backward pipe 14b have a counterflow, so that the heat exchange efficiency is improved.
