Abstract

The design of the new type of solar water heater built into the façades did not come from chance. It relies on "prerequisites" and previous studies, namely a) knowledge of the constitution of the solar water heater with its two components solar collectors and storage b) The existence of the well-known Trombe wall concept, c) The façade heating itself formed by solar air collector, d) Our patented innovation since 1989 for the integrated storage solar water heater. The solar water heater type integrated storage solar collector is integrated to the wall facade to reduce the cost and to better intercept solar radiation in winter when the need for hot water are the most important. Moreover, to save hot water for several days, we rely on another concept which is the thermosiphon solar water heater that we have developed and innovated by removing all threaded connections and / or Internal soldering to the solar collector and storage of hot water, thus resulting in innovation of solar water heater wall with thermosiphon, where the collector is in the facade and storage inside. The solar water heating system performs well since a temperature of 64°C should be reached in winter.
