the houses, where they can be divided 

 into two 3-iiich flows for each house. 

 If more convenient, it will answer if 

 the four 3-inch flow pipes are connected 

 'lirectly with the boiler. The main re- 

 turns should be of the same size as the 

 flow pipes. If the highest point of each 

 flow pipe is connected with the expan- 

 sion tank, there will be no occasion for 

 using air valves. 



A PARTITIONED GBEENHOUSE. 



In piping a house fifty feet long, 

 containing solid beds, how should we 

 arrange the piping from the outlet of 

 the flow pipe? Should we use return 

 bends on the walls? Our house is 

 now 15x20; that is, it is twenty feet 

 wide and as yet only fifteen feet from 

 gable to gable. We want to lengthen it 

 fifty feet, making it 20x65. We will 

 leave the glass end in the present 

 liouse as a partition, so we can heat it 

 to 60 degrees at night, while the new 

 part will require a night temperature 

 of 50 degrees. This 15x20— the old part 

 —is sunk in the ground two feet; the 

 addition will be above ground. Our 

 iiot water heater has two 2-inch flows. 

 Would it be best to run both of these 

 to the far end of the sixty-five feet 

 and then run to the returns into the 

 eighteen 1%-inch pipes under the 

 benches of the 15x20, connecting them 

 when the returns get back to the 15x20? 

 If you think our plan of eighteen 1^- 

 inch pipes in the 15x20 is not correct, 

 please advise us. We use galvanized 

 pipe. 



We thought of using one flow for 

 each part, one for the 15x20 and one 

 for the addition, but do not believe 

 that one will heat the addition in this 

 section of Michigan, where the outside 

 temperature sometimes drops to 15 or 

 20 degrees below zero. Would a valve 

 'n the flow pipe help to control the

Two Tank Traps vs. One Tank Traps 



Orders for our TWO TANK TR4P8 are 



being repeated and qnadrupled by the largest 

 manufacturers in the Tnlted States. We will fill 

 your order just as quiokly as th« repeat orders. 



The Canadians killed Reciprocity, but they 

 buy our traps and pay big duties on them This 

 is good evidence that our traps are a huge success. 



Let us return the oondenaation to your 

 boil> rs and save the heat units. Our traps do the 

 work forone-tepth of the steam required by pumps. 



Will the saving paj? 



Try our traps and be convinced.
