that a rough pipe, by furnishing more 

 surface, is more effective for radiating 

 heat than one that is smooth and 

 glossy. 



COAL OB NATUBAL GAS? 



Which would be cheaper to burn in 

 this section of Missouri, natural gas at 

 30 cents per thousand square feet or 

 steam coal at $2.9Q per ton in the bin? 

 We are about ninety miles south of 

 Kansas City and have 50,000 square 

 feet of glass. What vpould it cost to 

 equip the boilers for burning gas? 



E. F. C. 



The comparative cost .of natural gas 

 and coal at the figures given would be 

 slightly in favor of the coal, but the 

 gas can be burned with little attention, 

 and if a steady pressure can be ob- 

 tained the saving in labor for firing, 

 removing cinders, etc., will make it 

 more economical in the end. The cost 

 for piping, burners, etc., for burning 

 gas is not great, but will depend upon 

 the style of burner, the number and 

 size of boilers, etc. Local gas fitters 

 should be able to give quotations. 



HOT WATEE CIECULATION POOB. 



I have two houses 100 feet long, one 

 twenty-four feet wide and the other 

 thirty-two feet wide. I have torn out 

 the glass that formerly separated the 

 houses. How many 2-inch pipes will be 

 required to keep the houses at the 

 proper temperature for tomatoes in 

 northern Illinois with a hot water sys- 

 tem? At present the 32-foot house has 

 sixteen 2-inch pipes; the 24-foot house 

 has twenty-two 2-inch pipes fed by a 

 4-inch main. Two coils are of six pipes 

 each and two of five pipes each. Each 

 coil is attached to a header, to which 

 the water is supplied as shown in the 

 sketch. (Sketch shows upright feed 

 pipe attached to lower end of header 

 connected with pipes lying one above 

 another.) Under no conditions am I 

 able to heat more than three pipes in 

 each coil; there is no circulation in 

 the others. I have been advised to 

 change the headers in this manner. 

 (Sketch shows header in horizontal 

 position, the pipes dropping a few in- 

 ches before running horizontally.) Can 

 you suggest any method that will give 

 me the benefit of all the pipes? 



E. C. S. 



The sketches submitted give little 

 idea how the pipes are arranged, ex- 

 cept that the coils are vertical, i. e., 

 the pipes lie one above another, and 

 that the feed pipe comes down from 

 above and connects with the bottom 

 of the header. Nothing is furnished 

 to show where, the main is located, 

 the height of the returns abbve the 

 heater, or the size of the feed pipes 

 leading to the coils. 



While a 4-inch flow pipe is large 

 enough for the house 24x100 feet, it 

 would be better to use four 2 1^ -inch 

 pipes as flows in this house, carrying 

 one on each eave plate and one on 

 each side of the ridge under a purlin. 

 Sixteen 2-inch returns will be suffi- 

 cient if the 214-inch flows are used, 

 but eighteen will be needed if the 4- 

 inch flow is retained. At any rate, 

 the feed pipes to the coils should be 

 2%-inch, and they should enter the 

 upper end of the headers. 



For the house 32x100 feet, five 2%- 

 inch flow pipes and four coils of five

Kroeschell Replaces 4 Cast Iron Boilers 



Previous to 1909, Mr. Schultz, of Menominee, Mich., heated his entire plant with cast 

 Iron boilers. It had been claimed that cast Iron boilers are superior to the Kroeschell. 

 Mr. Schultz is now heating 18,000 sq. ft. of glass with the Kroeschell which was In- 

 stalled In 1909, and they are required to Are same only twice a night. The following 

 letter speaks for Itself: 



"We do not have the least trouble to maintain about 60 degrees in tlie coldest 

 weather. Your Kroeschell Boiler is the best I ever had. Before I heard alK>ut your 

 boiler I had four cast iron boilers, and I wouid not part with the Kroe sche ll for a 

 hundred cast Iron boUers now." (Signed) CHARLES SCHULTZ.

Kroeschell Replaces 2 Cast Iron Boilers 



The MarysviUe Floral Co., of Marysville, O., installed a No. 4 

 Kroeschell Boiler In 1905. Previous to this time they used cast Iron 

 boilers. The following letter speaks for Itself: 



"Has the Kroesch^I given entire satisfaction? Yes! We had 

 two cast iron boilers, but yours proved by far the best. Your boiier 

 has already outlasted the two cast iron boilers by five years, and all 

 the ezpenite that we liave been put to was a smoke dome."

Kroeschell Replaces Cast Iron Boilers 



The range of C. Peterson & Son, at Escanaba, Mich., was formerly heated by cast 

 IroB boilers. Last season this firm installed their first Kroeschell, a No. 6, which is 

 now heating 13,000 to 14,000 sq. ft. of glass. They state that they fire these boilers 

 three to four times during the night in zero weather. Under date of June 28, 1913, they 

 write as follows: • 



"The Kroeschell Boiler has given better satisfaction than any other boiler we have 

 ever had. For years we have flred many difTerent boilers, and really never could get 

 one that we might say was entirely satisfactory — there was always something wrong — 

 but now since we have tried the Kroeschell, we have solved our boiler proposition. We 



have a ( ) oast iron sectional boiler here, only used two years, and we wish we 



could get rid of it and put in another Kroeschell in its place." 



Escanaba, Mich., June 28, 1913. (Signed) C. PETERSON ft SON.
