The T-COSY solution is a complete solution for instantaneous domestic hot water production with primary storage and condensing gas boiler.

The principle of T-COSY is to produce instantaneous hot water from primary storage to reduce the risk of legionella. The solution can thus operate with low primary return temperatures to optimize the efficiency of the system with the condensing boiler. The plate heat exchanger is protected against limescale deposits.

Thanks to its original design in the form of light and compact modules, the handling is very simple and the installation times are considerably reduced.
