| * | Average American | US DOE EERE Advanced Manufacturing Office 2012 Return Condensate to Boiler | USA: Steam heating system () | 0.65 | proportion (0-1) | "A large specialty paper plant reduced its boiler makeup water rate from about 35% of steam production to between 14% and 20% by returning additional condensate. Annual savings added up to more than $300,000." |
