<p>The system can be applied to any type of central heating and gives a gain of energy by using a coil circuit with the heat exchanger at the condenser of a cooling circuit. The solar panel is in three layers of cells, and the copper pipes carrying the working fluid pass through the lower of the three cells. The system works in summer and in winter, uses low cost materials and can be used in several locations such as glazed bays, roofs or veranders and does not spoil the aesthetics of the building.</p> |
