The solar water heater has a loop of memory material (2), with leaves (3) in thermal contact with the reservoir (7), which in the 'cold' state, separate the thermal contact between the leaves and the ray absorbing surface (5). - Thermal loss is limited by a combination of the reservoir insulation (6), two ring insulation pieces (4), and a thin layer of insulation material (10) at the reservoir centre. When solar rays pass through the transparent cover (11), a flat surface (1) is heated and transmits its heat to the loop, which expands and transmits its movement to the wings (3), which make contact with the absorbing surface and allow heat transfer from the absorbing surface to the reservoir.(A/2)
