ThermoHexa heat interface units use temperature-based thermostatic control. Domestic hot water preparation and heating operate simultaneously. The thermostatic valve reduces heat loss. Compact design enables easy installation. Heat exchangers and pipes are manufactured from AISI 316 stainless steel.
This model provides combined domestic hot water (DHW) and space heating (SH). Thermostatic control manages both circuits simultaneously.
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.
