Increasing condensate return savings estimator for steam and condensate systems

Use to estimate savings from increasing condensate return in a steam and condensate system

Amount of extra condensate to be returned
Temperature of extra condensate to be returned prior to hotwell feedtank
Cold water make up temperature
Hours of operation per year hr/annum
Fuel type
Cost of fuel (per kwh gas, per ltr oil, per kg coal) £
Steam boiler efficiency %
Raw water cost £/per 1000L
Water treatment cost £/per 1000L
Effluent cost £/per 1000L
Amount of extra condensate recovered per year
Fuel savings over period£/annum


Typical calorific values for the fuel are used. These may vary

Figures calculated are of a simple theoretical nature and other variables may need to be considered depending on application
