The use of transparent insulation material in such
water heating systems increases its efficiency and provides hot water
at higher temperature as compared to conventional integrated
storage solar water heater with glass glazing. The ICSSWH, by its
combined collection and storage function suffers substantial heat
losses to ambient, especially at night-time and non collection periods.
To be viable economically, the system has evolved to incorporate new
and novel methods of maximizing solar radiation collection whilst
minimizing thermal loss
