YORK® Intelligent Water Ecosystem (IWE).
An integrated hydronic HVAC system that intelligently coordinates chillers, pumps, terminal units and controls to optimise comfort, energy use and system reliability.
One intelligent system, from room demand to the water plant.
The YORK Intelligent Water Ecosystem connects the chiller, water circuit, terminal units and room controls through one coordinated control system.
Instead of operating each component independently, IWE continuously monitors actual indoor demand and system conditions. It then adjusts the chilled-water temperature, compressor loading and pump operation to maintain comfort while reducing unnecessary energy use.
The system can support cooling, heating, domestic hot water, fresh-air systems and compatible hydronic terminal units.
IWE thermostats collect real-time information including room temperature, temperature setpoints and operating status. The system also monitors chilled-water temperature, chiller loading and outdoor ambient conditions.
The AIoT-based control logic evaluates indoor and outdoor conditions to determine how much cooling or heating is required across the system.
The chiller, pumps, valves and terminal units are adjusted as one coordinated system. Chilled-water temperature, compressor loading and pump operation are continuously optimised according to demand.
By matching system output to actual load, IWE maintains stable indoor conditions while reducing unnecessary pump operation, compressor cycling and overall energy consumption. Where heat-recovery equipment is selected, recovered heat can also be used to produce domestic hot water.

Smarter control across the whole system
IWE coordinates the chiller, pumps and room terminals in real time to improve comfort, efficiency and reliability.
Efficiency through continuous system optimisation.
Traditional HVAC components are often controlled independently and may continue operating even when demand is low. YORK IWE coordinates the complete hydronic system and continuously adjusts its operation according to real-time room and equipment conditions.
The YORK catalogue indicates potential operating-cost savings of approximately 8%–18% through adaptive chilled-water temperature control, compressor-load optimisation and demand-based pump operation.
