Your ground source heat pump was a significant investment. But without monitoring, you have no idea if the loop temperatures are optimal, if the COP is degrading, or if the compressor is working harder than it should.
Ground loop temperatures drift seasonally. Without monitoring, you can't tell if the loop is underperforming or if the heat pump is compensating by consuming more electricity.
Geothermal COP should be 3.5-5.0. Without live data, a system running at COP 2.5 goes unnoticed — costing you 40% more in electricity.
Compressor issues, circulation pump failures, and antifreeze degradation happen silently. By the time you notice, it's an emergency.
Nexus Geo connects directly to your geothermal system and delivers complete visibility — from ground loop temperatures to compressor health and energy draw.
Track supply and return loop temperatures in real time. Detect seasonal drift, identify underperforming boreholes, and ensure your ground loop is delivering optimal thermal exchange year-round.
Learn more →Live coefficient of performance calculation compares thermal output against electrical input. See exactly how efficiently your system is running and get alerted when COP drops below target thresholds.
Learn more →Monitor compressor run hours, discharge temperatures, suction pressure, and superheat. Detect refrigerant degradation and mechanical wear before they cause a breakdown.
Learn more →Monitor circulation pump status, flow rates, and power consumption. Detect pump failures instantly and optimise run schedules to reduce parasitic energy losses across the loop field.
Learn more →See exactly how much energy the heat pump, circulation pumps, and auxiliary systems consume. Benchmark performance across seasons and prove energy savings with exportable reports.
Learn more →Track buffer tank stratification temperatures at multiple points. Ensure the tank is charging and discharging correctly, and detect issues like short cycling or insufficient thermal storage capacity.
Learn more →Nexus Geo is system-agnostic. Whether you have a closed loop borehole array or an open loop water source system, the platform adapts to your configuration.
No complex rewiring. Nexus Geo connects to your existing geothermal system and starts streaming data immediately.
We assess your geothermal system — loop configuration, heat pump model, buffer tank setup, and existing controls — to determine the optimal sensor and controller placement.
Install the Nexus Geo controller and Universal Expansion modules. Strap-on sensors connect to loop pipework, buffer tanks, and heat pump refrigerant lines without breaking into the system.
Set alert thresholds for loop temperatures, COP targets, compressor discharge limits, and circulation pump status through the Nexus iQ™ dashboard.
Live data flows to the cloud: loop temperatures, COP, compressor health, pump status, and energy consumption. Accessible from any device, anywhere.
From residential ground source systems to commercial borehole arrays, Nexus Geo delivers continuous monitoring across Australia.
The Nexus Geo ecosystem gives you everything you need to monitor and control your geothermal heat pump system.
Purpose-built controller for geothermal heat pump systems. Monitors loop temperatures, compressor health, and system efficiency with cloud connectivity.
