Miles of Steam Pipes 

 Millions of Heat Units 



In the miles of steam pipes that heat your green- 

 houses, steam containing many dollars' worth of heat 

 units is condensing into water every season. 



Of course, you are drawing this water off— for the 

 heating plant will not do its work unless the pipes are 

 kept clear— but in drawing it off. are you wasting the 

 heat units that remain in the hot water? 



Water from city supply is usually about 60° F., but 

 from a well, considerably colder. The boiling point 

 of water is 212° F., and the temperature of the con- 

 densation in your pipes but a trifle below that. 



In other words, if you are not utilizing the hot water 

 that condenses in your heating coils you are wasting 

 enough coal to raise the water almost 160°. 



And when you consider the amount of water that must 

 be turned into steam to supply your heating coils, you 

 can see that this is no small item. 



There is a way to remove the condensation from your 

 heating plant and "boost" it again into steam. 



The "Detroit" System, once it is installed, will do 

 this automatically:- There are no pumps to watch, no 

 drain cocks to open, no power used in operating the 

 device. 



The "Detroit" System has advantages over the pump 

 or other means of handling condensation. 



It returns the water to the boiler just a trifle under 

 the boiling point; there is no waiting for the water 

 to cool. 



There is a "Detroit" System to meet every problem of 

 condensation. 



Just write the particulars about your greenhouse 

 heating plant, and we will send you full description 

 of the "Detroit" Systems and will advise you as to 

 which one best suits your needs. ■ - — . ,
