SPLIT SYSTEM FOR HEATING AND STORING WATER FOR SOLAR HEATING PLANTS AND RELATIVE METHOD TO CONTROL OPERATION OF THE SYSTEM

摘要

There is described a system for heating and storing water comprising: a sanitary water circuit and a thermal fluid circuit; a solar thermal plant (5) in which said thermal fluid circulates; a primary boiler (B1 ) and a secondary boiler (B2) the secondary boiler having a greater capacity than the primary boiler (B1 ) said sanitary water and thermal fluid circuits passing through said primary and secondary boilers; means to control circulation of the thermal fluid configured to cause circulation of the thermal fluid in a circulation circuit (7A 9 12) in said primary boiler (B1 ) until reaching a first temperature of the sanitary water and/or in a circulation circuit (7B 1 1 12) in said secondary boiler (B2); means to control the circulation of sanitary water configured to cause inflow (1 ) of the sanitary water to be heated in said secondary boiler (B2) passage (2 3) into said primary boiler (B1 ) and outflow (4) from said primary boiler (B1 ) toward the user.
