Energy
Steam Trap Loss Calculator
Calculate annual steam loss, energy loss and cost from a leaking or failed-open steam trap.
Use a measured or estimated steam-loss rate. Do not infer leakage from pressure alone.
Optional energy-loss estimate. Edit using an appropriate steam enthalpy basis for your system.
Annual Steam Loss
—
Estimated steam lost during the entered annual operating period.
Annual steam loss
—
Steam loss per day
—
Steam loss per operating hour
—
Annual energy loss
—
Annual cost loss
—
Average cost per operating hour

Method:
Annual steam loss is:
Steam Loss =
Leak Rate × Operating Hours
The calculator converts the leak rate internally to kg/h and reports annual loss in tonnes.
Steam loss per operating day is estimated from:
Daily Loss =
Annual Steam Loss ÷
(Operating Hours ÷ 24)
Annual cost loss is:
Cost Loss =
Annual Steam Loss × Steam Cost
If steam energy content is entered:
Energy Loss =
Annual Steam Loss × Steam Energy Content
The default steam-energy value is only a placeholder for a practical estimate. Actual steam energy content depends on steam pressure, temperature, condensate return conditions and the energy basis used.
This calculator intentionally does not estimate trap leakage from steam pressure alone. Actual leak rate depends on trap type, failure mode, orifice condition, differential pressure and operating state.
For energy-audit use, obtain leak rate from trap testing, ultrasonic surveys, discharge measurements or a defensible engineering estimate.
