Domestic Hot Water Mixing Valve Upgrade

How has this idea enhanced your club's operation, etc.?

The new Domestic Hot Water (DHW) system upgrade has been in place for approximately one year, allowing the Club to collect meaningful performance data and user feedback. The original project replaced an aging wax-ring mixing valve — previously responsible for mechanically controlling water temperature based on differential heat — with a modern digital valve assembly capable of real-time monitoring and near-instantaneous adjustment. The new digital system utilizes high-resolution temperature sensors and automated three-way valves to continuously regulate domestic hot water with exceptional accuracy.

Beyond improving user experience, the system operates significantly more efficiently. By minimizing delta-T swings and fine-tuning flow with frequent micro-adjustments, the system requires less make-up water to maintain setpoints. Unlike the previous mechanical system — which required seasonal parameter adjustments to compensate for heat loss throughout the building — the new assembly automatically accounts for infrastructure-related temperature drops. This is achieved through programmed compensation logic informed directly by the digital sensors and three-way spring-return valve operation.

How was this idea implemented, and what have been the club members' reactions?

Thanks to this upgrade, the Club significantly reduced service calls related to fluctuating or insufficient hot water — especially in the locker rooms, where complaints were most frequent.

Overall, the project has delivered measurable improvements in reliability, energy efficiency, and Staff time savings, while providing Members with more consistent and comfortable hot water service year-round.
