Water Heating System. (Pots above Jerusalem)
1.1 Introduction.
As still it states in the art a water tank placed above
solar panel to make convection flow possibility.
Shown in Fig.1. Other non-worst illustrations may be found in attachment.
Drawbacks. The first is trivial, it not makes a pleasant look. The second it needs to provide electrical power and full flow tubes to the roof. And the last is more significant. Each time you need a hot water you have to throw out to sewerage amount about 5…10 liters. This in dependence on distance from the roof to your floor.
This mean that about 8750 liters per year for one family losses. The losses of water for a whole city is about 1575000 m3/ year.
Possible partners / investors of the project may be city hall, building companies, the systems manufacturers.

1.2 First stage of the project development.
As planned at first stage may use almost all existed components with minimal changes.
The first step is to place water tank in the service balcony, as it shown in Fig. 2.
Such displacement required circulate tubes (3/8’’) and pump (2 l/min, 30m pressure). In this way all drawbacks may eliminated. The similar systems just exist in new multistory buildings with some none principal difference.
So, it will no difficult to get required regulations.

1.3 Second stage of the project development.
During last several tenths of years were a lot of attempts of solar energy usage. The only a few of they were successful. And no one of they were undoubtful profitable. This relates to all types of systems: Dish (Spain), Tower (Weitzman institute), widely applied Photo Voltaic panels, Huge scale of Through panels (Solel). The last was the best in the sense of functionality. (Hence was buried by Siemens company). After analysis it were revealed some advantages of through type systems but in the scale suitable for domestic usage. It seems rational to organize their development.
