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 of0.0015 minthickness 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
