Balanced domestic hot water

Honeywell, DHW, balance, balancing

Honeywell’s Kombi 4 valve provides a low-cost means of ensuring immediate hot water and reducing water wastage while enabling easier and faster commissioning in buildings with many DHW outlets. These throttle and balancing valves are installed in the secondary return of constant hot-water systems to balance them. A optional thermostatic control attachment additionally maintains constant circulation temperature.

Kombi 4 valves allow easy thermal flushing as required daily for legionella prevention. The temperature control is typically set for 50 to 55°C for normal operation. When water at 70°C is flushed through the system for thermal disinfection, the valve automatically opens further to ensure hot water is rapidly distributed in all risers and pipelines, whilst maintaining the balance.

These valves have a visible presetting dial with a concealed presetting handwheel.
