The results of several solar systems fitted with the heat transport system developed at the JRC - Ispra are presented. The 10 m2 plant, installed at a textile company, transports the heat against a height of 8.5 m and has been working for 3.5 years. Two other plants, with 4 and 6 m2 of solar collectors, have been installed at two mountain shelters, for the heating of domestic water or, during the cold season, for the production of water by melting snow. Recently the operating scheme has been modified; this new scheme, with a higher efficiency, uses a double-effect valve, already available on the market and tested up to a high number of cycles.
