One model of the proposed CSWH system was designed and
built to investigate the performance of it. Fig. 1 a shows the schematic cross-section of the components of the experimental model.
In Fig. 1 b the locations of the thermocouples into the water storage
tank have been shown. The water storage tank was constructed
from galvanized sheet of 0.0015 m inthickness and the volume
of 1.45 0.56 0.17 m3 .It was located inthe thermally insulated
box from 40 mmtick rockwool . Two transparent glass covers were
