  • Page 3 According to this medieval saying by William of Ockham we should only use the elements we really need, by shaving off (hence the expression “Ockham’s Razor”) that which is superfluous. Following this philosophy EDN has shown the world the new direction of solar energy for heating.

  • Page 5 ENERGY BY NATURE T120 T150 T200 T250 THE ANSWER TO AN ACTUAL NEED “Domestic heating accounts for 25/30% of the world’s total atmospheric emissions. If we add also the industrial consumption of hot water, this percentage increases significantly. Today, such a huge energy need is still met through the use of fossil fuels that now represent a real threat to all of humanity.

  • Page 6: How It Works

    RADIASOL consists of a radiator with cylindrical tubes interconnecting containing water that absorbs solar radiation directly through the gasified double-glazing. It uses the best available solar radiation thanks to its particular constructive technique (EDN patent) and the thermal mass of its elements (stainless steel, water, glass) without accumulation, antifreeze and recirculation pumps.
  • Page 7 ENERGY BY NATURE DIRECT EXCHANGE RADIASOL is an integrated (collector-storage tank) system that directly transfers the solar radiation to the water contained within it. It contains less water than traditional systems with storage tank but the sun heats the three masses of the elements that make it up (double-glazed panel, radiator’s steel body and the water inside) employing the thermal inertia of the mass.
  • Page 8 ENERGY BY NATURE DIRECT EXCHANGE - THE DOUBLE-GLAZED PANEL The direct exchange technology, combined with the double-glazing is the only solar thermal technology that ensures high yields even in winter. The glass’ thermal transmittance and its solar factor are the key factors influencing the efficiency of a solar thermal system.
  • Page 9 If a horizontal position installation is chosen (fig. 2) layering does not occur and, in the same climate conditions, the output water is at 45 °C. EDN recommends using RADIASOL horizontally only in climatic zones with insolation values above 2000 kWh/m2 per year.

  • Page 11 Data provided is merely an example RADIASOL is marketed in Italy and abroad through specialized distributors of plumbing products. To see firsthand the unique performance of our technology, EDN recommend visiting our authorized distributors with RADIASOL exposed to the sun, especially in cold weather.
  • Page 12 • Prevents condensation on the glass and exploits 100% of solar radiation. This technique (patent solution EDN) involves a small power consumption (10-15 euro per year depending on the installation location). The map shows locations with RADIASOL systems installed through which EDN executes performance tests throughout the year.
