When the valves 24 are opened simultaneously or alternately, the floating valve 14 or the floating valve 14& is displaced by water pressure to the open side, thereby forming a hot water supply system D. The hot water system D can be combined with a normal solar water heater, or the hot water stored in the hot water storage tank 8 can be connected to a normal instantaneous water heater to produce desired hot water during non-sunshine or cold weather. Of course, you are free to make changes and deviations without any restrictions.

Now, solar heat from sunlight is collected by a heat collection pipe lK@, and the pipe l
To change the cold water that passes through the interior as a Yr heat receiving medium into the desired hot water, first set the desired temperature value, for example 40°C, on the thermostat B of the hot water supply system D, then turn on the switch and open the solenoid valve. Then, when the valve is opened, water flows into the heat collecting pipe 1, and while the water passes through the horizontal pipe 80 and the skeleton 80 and moves up in the vertical pipe 29 arranged on the slope 2, the internal cold water pipe 1 is heated. , due to the synergy and effects of the thermal conductivity of each vertical pipe g9, its inner diameter, flow ratio, length, etc.

(1) Install heat collection piping on roofs, building rooftops, gardens ~
Piping is installed in a lattice-like or serpentine shape on the slope of a thermally conductive flat plate, etc., in the long direction of the slope, so simple equipment can sufficiently absorb solar heat and provide cold water in a short period of time. You can change it to the desired hot water.

(2) A solenoid valve and a detector are placed on the water supply and hot water supply routes, and the two are linked via a thermostat, so the detector can detect a low temperature value based on the temperature value set in advance on the thermostat. When hot water of The temperature of the supplied and stored hot water can be maintained constant at all times.

(8) We designed a system that allows hot water to be supplied to the bathtub using a pipe pipe during the day, and at the same time stores hot water in the hot water storage tank by making the most of the daylight hours. You can secure enough hot water for washing dishes, bathing, etc., so you can almost eliminate your utility bills, and at the same time, you can use hot water at the right temperature for bathing small children, washing hands, and flushing the toilet bowl. You can use your toilet comfortably without the hassle of having to do it.
In particular, during defecation in winter, the area around the sluice can be warmed and moistened with hot water, which not only makes defecation easier, but also has a great effect of keeping the sluice and surrounding area clean at all times. In the middle of the water supply pipe that connects the water supply pipe, we installed a drain ring that disconnects the water supply source and drains the secondary pressure side, so it can be used when not in use at night in cold regions or during snowfall. It is possible to reliably protect heat collection pipes, water heaters, water supply pipes, hot water supply pipes, etc. from freezing.
