Better and Cheaper than Any Other System 



Zanesvillk, ()., Feb. 11, 1911. 

 Gentlemen : In regard to the Kroeschell Threaded Tube Piping System, I 

 think it is better than standard piping system, not only in being cheaper, but 

 thinner, and giving more heat. I found the Generator was a paying proposi- 

 tion and would recommend its use to all using a hot water system. My No. 11 

 Boiler does the work satisfactorily on over 25,O0Orsq> ft. of glass. 



Very truly yours, C. L. Humphrey.

wall. The ends and partitions will be 

 glass, except three feet of double 

 siding. 



There will be three apartments, 

 forty-one feet, twenty-nine feet and 

 ten feet long, respectively. The 10- 

 foot section will be between the other 

 two and will be used as a potting 

 room; the boiler will be in a pit under 

 Mils part. I shall probably use a sec- 

 cional hot water boiler. I shall use 

 raised benches and should like to run 

 1%-inch return pipes under them, with 

 2^-inch flows on the purlins. 



Should the flows run uphill or down- 

 hill? How many pipes will be required 

 to heat the 41-foot part to 50 degrees, 

 for carnations, and the 29-foot part to 

 55 degrees, for pot plants, in zero 

 weather? What would be the best way 

 to arrange the pipes and where should 

 valves be placed? Could the expansion 

 tank be put lengthwise directly under 

 the angle of the roof, or what would be 

 the best place for it? P. A. D. 



In the house 21x41, use three 2i^- 

 inch flows and ten 1%-inch returns. 

 Carry one of the flow pipes about two 

 feet under the ridge and the others on 

 the plates. Give the flow pipes a slight 

 fall. For the other house use three 

 2M:-inch flow pipes, arranged as above, 

 and twelve IV^-inch returns, carrying 

 four under each bench. 



If there is no place where the ex- 

 pansion tank can be located so that it 

 will have greater elevation, it' can be 

 under the ridge, as proposed. It will 

 be well to have a valve on each of the 

 flow pipes, wherever it will be most 

 convenient. For the main flow and 

 returns use 3-iuch pipes, breaking each 

 up into three 2i/.-inch pipes.
