Solar collector from a hose or flexible pipe

two threaded rods;
propylene corners, fittings must have external threaded connections;
PVC plastic pipes: 2 pcs, length 1.5 m, diameter 32;
2 plugs.
The pipes are laid in parallel in the housing. They are connected to the hot water supply through shut-off valves. A thin cut is made along the pipe, into which a polycarbonate sheet can be inserted. Due to the thermosiphon principle, water will independently flow into the grooves (cells) of the sheet, heat up and go into the accumulator located at the top of the entire heating system. Silicone resistant to thermal effects is used to seal and fix the sheets inserted into the pipe.

To increase the thermal efficiency of a cellular polycarbonate collector, the sheet is coated with any selective paint. Water heating after applying the selective coating accelerates approximately twice as fast.

Those who have a private house with a garden or a summer cottage, of course, know that the water left in temporary light mains after watering the beds quickly heats up. This kazakhstan mobile database quality of hoses or flexible pipes was used by folk craftsmen, creating solar heat exchangers from them. It should be noted that such a collector will cost many times less than one bought in a store, but in order for the manufacturing process to be successful, some effort must be made.

Such a collector can consist of one or several sections, into which hoses tightly coiled in a spiral “snail” are placed and secured.

This design can be called the simplest both in design and installation. Its main disadvantage is that it is practically impossible to use it without forced circulation, since with too long pipe circuits the hydraulic resistance will exceed the pressure force created by the temperature difference. However, it is not difficult at all to solve the issue of installing a circulation pump. And such a system installed in a country house will be a great help and will quickly pay for itself, including the costs (very insignificant) for powering the pump.

Such collectors are also used to heat water in swimming pools. They are connected to a filtration system, which is necessarily equipped with a pump. The water, circulating through the collector pipes, has time to heat up before entering the pool.
