SmartHexa heat interface units provide both hydraulic and thermostatic control. The cold exchanger principle eliminates limescale buildup. SmartHexa units prioritize domestic hot water production. Heat exchangers and pipes are manufactured from AISI 316 stainless steel.
This model provides combined domestic hot water (DHW) and space heating (SH). DHW priority mode ensures user comfort is maintained.
The Indirect series acts as a pressure breaker in high-rise buildings, enabling removal of intermediate mechanical rooms. Heating operates as a closed system through a separate exchanger circuit.
