MYdens 60 wall hung 60 kw IT ALWAYS WORKS IN CONDENSING MODE SO IT IS IDEAL EVEN WITH RADIATORS Usually a standard condensing boiler works in condensing mode only in combination with low temperature heating systems. This happens because the floor heating installation works with water at low temperature and the condensing boiler reaches its maximal efficiency at this condition. But traditional radiators need to be heated with high temperature water and traditional condensing boilers do not condense when they work at high operating temperatures. Thanks to the innovative, wide surface, patented R.V.C. heat exchanger of MYdens 60 flue gases condense at 55 C return temperatures, working always in condensing mode also in installation with radiators. For this reason MYdens 60 is the ideal condensing boiler not only for new installations, but also in the replacement market. 10
