Hot Water When It's Needed.
Not a Drop More Than Necessary.
Domestic hot water is one of the most resource-intensive —
and most overlooked — systems in any commercial building.
It runs continuously, serves dozens to thousands of endpoints, and in most facilities
operates with little more visibility than a thermostat and a water bill.
The result is a system that wastes energy keeping water hot that no one is using,
delivers inconsistent temperatures that frustrate occupants, and
conceals inefficiencies that silently erode your operating budget.
BluSENSE brings full-system intelligence to hot water — optimizing delivery,
reducing waste, and ensuring performance you can measure and defend.
The Hot Water Management Problem
The Problem with "Set It and Forget It"
Most hot water systems are designed once and largely left alone. Recirculation pumps run on fixed schedules that don't reflect actual demand. Water heaters maintain temperatures around the clock regardless of occupancy. Distribution inefficiencies go undetected until energy bills or occupant complaints make them impossible to ignore — and in large buildings, domestic hot water is one of the biggest contributors to total energy consumption, much of it unnecessary.
How BluSENSE Optimizes the Entire Hot Water System
BluNODE sensors deploy across your hot water infrastructure — at heaters, recirculation loops, distribution headers, risers, and end-use points.
Built for Every Stakeholder
Hot water intelligence delivers value at every level of your organization.
Precise control and visibility over a system that typically runs in the background — reducing complaints, simplifying compliance documentation, and eliminating guesswork from maintenance decisions.
Reduce domestic hot water energy costs, extend equipment life through optimized operation, and demonstrate measurable utility performance to tenants, investors, and acquisition teams.
Continuous performance data to validate distribution design, identify recirculation inefficiencies, and support system modifications with real-world evidence rather than assumptions.
Quantify hot water energy reduction, track water consumption trends, and produce documented performance records for green building certifications, ESG reporting, and benchmarking ordinances.
Beyond Efficiency — A Compliance and Risk Management Tool
Hot water systems carry real regulatory and liability exposure. Legionella proliferates in water that sits at inadequate temperatures in under-utilized distribution loops. Compliance with ASHRAE 188 and local health codes depends on maintaining and documenting temperature ranges throughout the system — not just at the heater.
BluSENSE provides a continuous, auditable record of system temperatures across every monitored point — giving facility teams, engineers, and risk managers defensible documentation without manual logging or periodic testing alone.
Hot Water Performance at a Glance
| Metric | What BluSENSE Tracks |
|---|---|
| Generation | Water heater output temperature, recovery cycles, equipment efficiency |
| Recirculation | Loop temperatures, pump runtime, heat loss across distribution |
| Distribution | Flow rates, pressure, temperature at headers and risers |
| End Use | Consumption by zone, demand patterns, peak usage windows |
| Compliance | Continuous temperature records for ASHRAE 188 and Legionella management documentation |
