The hot-water loop ΔT collapses while the boiler runs.
The hot-water loop ΔT collapses while the boiler runs.
Over-pumping and bypassed coils raise pump energy and return temperature (killing condensing).
Check three-way valves and bypasses, pump speed / ΔP reset, and coil control valves.
How Energy Agent prices a finding
Estimate the extra pump energy from moving more water than the load needs.
Enter positive numbers to see an estimate.
Pump power rises with the cube of flow. At design ΔT the loop needs only (actual ÷ design) of today’s flow, so pump power at design would be that ratio cubed. Energy Agent measures ΔT and pump power from the plant trends.
Screening estimate. Energy Agent measures the real fault hours and load from your trends and prices them at your tariff.
Screening-level estimates; confirm with measurement and verification before capital commitment.
The chiller is on but CHW supply temperature is above its setpoint by more than the tolerance.
The chilled-water loop's supply-to-return delta is below design when the chiller is loaded.
The chilled-water supply setpoint stays flat for weeks while the weather swings.
The condenser-water setpoint never follows the wet-bulb.
