(Continued on Page 41) THE SATURDAY EVENING POST 39 How a Pot of Coffee Saved $1502* WORKMEN in a certain plant found the barehot surface of a steam chest a most convenientstove on which to heat their coffee.Refilled by each oncoming shift, it became a con-tinuous service to coffee drinkers—and as it turned outit was the means of teaching the plant management avery valuable lesson. One day a Johns-Manville man (a Waste Killer) hap-pened in, saw the simmering brew and used the instanceas a simple demonstration of the way heat intended forpower alone was being wasted by many surfaces through-out the plant because of the lack of proper insulation.The calculations given in detail below* show that theplant was losing $1615. yearly in this way. Insulationcut the loss to $113., an annual saving of $1502. Through Johns-Manville, Insulation has become anexact science. Read about it.

There are hundreds of places where heat is beingwasted at a much greater rate than in this conservativecoffee-pot instance, and at a greater expense because fuelcosts more than ever. Many surfaces regarded as insulated are wasting almostas much heat as if they were bare—so poor is the protec-tion their covering affords. For rule-of-thumb often regulates the application of so-called Coverings. In fact, guess work coined the phrasepipe covering, a mysterious material that may have littleto commend it except that it saves some heat. Today there is an expert technology in Insulation.Johns-Manville now maintains a national service in Insula-tion for all fuel users. It is based on sound engineeringpractice, made practical through materials of known meritas heat savers. Moreover, it is possible to calculatelosses from present faulty materials now in service and topredict new savings under corrected conditions. And in this day of high coal prices it is nowonder that Industrial Management ea
