    You walk through the village and you are amazed: at each site there is a “summer shower” booth with a black barrel on the roof. Such a “shower” is suitable only with a hangover - even on a hot day, the water in your barrel will not warm up properly! But it’s not difficult to get hot water without messing with a dangerous electric boiler in the basin.
    How much of the barrel area on the roof do you think is exposed to direct sunlight? 20 per cent. The remaining 80, according to the laws of physics, give off heat. Add to this the breeze -I and all the futility of the idea is obvious.

    All you need is a box. We make its side facing the sun from a strong transparent film, and cover the rest with a heat insulator (at least we just fill up the sawdust). That's all, but the temperature of the water in the barrel will now be constantly 60-70 degrees, and no problems with electricity bypassing the meter!
    You can also get hot water. To do this, it is enough to attach two pipes to the barrel - one at the very bottom, the other at the top. We connect the nozzles with a black hose coiled into a spiral, and the hose itself is placed in a box, glued inside with foil, with a film wall on the sunny side. But there is one “but” here: there should not be air pockets in the hose, which means that constant circulation of water is necessary, i.e. as water is consumed, the barrel should immediately be replenished with a new one.
