Warm Water Valve
Warm Water Valve
Reliable temperature control with minimal pressure drop
The Rinnai Demand Duo Warm Water Valve (DDWWV) is a high-performance circulating warm water valve that accepts hot water at 60°C or higher from a storage system and delivers a consistent, reduced outlet temperature across a full range of flow rates with minimal pressure drop.
Ideal for commercial applications such as apartments, hotels, hospitals, and nursing homes, the DDWWV can replace multiple tempering or thermostatic mixing valves (TMV) with a single centralised solution, simplifying installation and maintenance.
The system features an intelligent electronic controller that continuously monitors the warm water outlet temperature. A magnetically actuated three-way mixing valve automatically adjusts to mix hot and cold water at the precise rate needed to maintain the programmed temperature. The outlet temperature can also be fine-tuned to account for temperature losses along the ring main, ensuring accurate and safe water delivery at every point of use.
