With each of curtains that you see in the balcony of the photo you can raise the temperature of 300 litres of water, increasing it from 12/14 degrees to approximately 60/70 degrees after a period of medium insolation of 6/8 hours. The balcony is exposed to West/Soutwest, to sun descent. This equipment can produce warm water to sanitary use, rendering a family of 4/6 persons self-sufficient during the period that goes from April to October (an integration is demanded during the days not sunned). In the other months of the year it contributes, in presence of the sun, to contain the consumption's.
