Your hydronic system heats zones unevenly, runs pumps when nobody is home, and gives you no visibility into buffer tank performance. You deserve better.
Most hydronic systems treat the entire building as one zone. Bedrooms overheat while living areas are cold. Underfloor circuits fight radiator circuits for flow.
Circulation pumps run 24/7 regardless of demand. Without flow monitoring, you can't tell if the pump is cycling efficiently or wasting electricity heating an empty building.
Buffer tank stratification issues go unnoticed. Short cycling, insufficient storage, and incorrect charging temperatures waste energy and reduce system life.
The Nexus Hydronic Controller connects to your pipework, pumps, valves, and buffer tanks — delivering per-zone control and complete system visibility.
Independent setpoints for every hydronic zone. Control underfloor circuits, radiator loops, and fan coil units separately — each with its own schedule, setpoint, and deadband.
Learn more →Track circulation pump run hours, power consumption, and flow status in real time. Detect pump failures instantly and optimise run schedules to eliminate waste during unoccupied periods.
Learn more →Monitor buffer tank stratification at multiple temperature points. Ensure correct charging and discharging cycles, detect short cycling, and verify thermal storage capacity is being used efficiently.
Learn more →Automated mixing valve management ensures each circuit receives water at the correct temperature. Underfloor loops get lower temperatures while radiator circuits run hotter — all managed automatically.
Learn more →Monitor boiler or heat pump performance — flow and return temperatures, firing cycles, and efficiency metrics. Detect issues before they cause comfort complaints or energy waste.
Learn more →See exactly how much energy each zone, pump, and heat source consumes. Generate automated reports to benchmark performance, prove savings, and identify optimisation opportunities.
Learn more →The Nexus Hydronic Controller integrates with any hydronic configuration — from simple underfloor loops to complex multi-source, multi-zone commercial systems.
No system replacement required. The Nexus Hydronic Controller integrates with your existing pipework and starts delivering data immediately.
We assess your hydronic system — zone layout, pump configuration, buffer tank setup, heat source type, and mixing valve arrangement — to design the optimal monitoring solution.
Install the Hydronic Controller and Universal Expansion modules. Strap-on and discreet sensors connect to pipework, manifolds, and buffer tanks without breaking into the system.
Set per-zone temperature targets, pump schedules, mixing valve parameters, and alert thresholds through the Nexus iQ™ dashboard. Group zones by floor, function, or tenant.
Live data flows to the cloud: zone temperatures, flow and return temps, pump status, buffer tank stratification, and energy consumption. Accessible from any device, anywhere.
From residential underfloor heating to multi-zone commercial hydronic systems, Nexus delivers precise control and measurable energy savings.
The Nexus hydronic ecosystem gives you everything you need to monitor, control, and optimise your hydronic heating system.
