flow pipe and taking it oflf at the height 

 of four feet. While it is desirable to 

 have the expansion tank more than one 

 foot above the flow pipe, it will be bet- 

 ter to make the change proposed than 

 to have it outside the house. 



Globe valves retard the circulation 

 to some extent, but whether it will 

 be better to discard them and pur- 

 chase new gate valves will depend upon 

 several things, such as the size and 

 length of the pipes, the amount of 

 radiation supplied through them and 

 the length of the pipes above the boiler. 

 The chances are about three to one 

 that the globe valves can be used 

 without seriously affecting the work- 

 ing of the system. 



ONE NEBRASKA HOUSE. 



Please state what piping will be 

 needed in my greenhouse, which is 

 20x96 and sixteen feet high to the 

 ridge. The side walls contain three 

 feet of glass. The boiler house is at 

 the north end and the office is at the 

 south end. The pipes to be used are 

 .S-inch flows and IV^-inch returns. The 

 boiler is 4x14, with a grate surface four 

 feet square. The temperature wanted 

 is 60 degrees. 



B. F. C. 



The letter does not state whether 

 steam or hot water is to be used. For 

 steam one S-inch overhead main and 

 eight l^,{.-inch returns would answer. 

 For hot water use three 3-inch flows 

 and fourteen l^j-iuch returns. Were it 

 not for the fact that the foregoing 

 sizes are on hand, I would suggest that 

 for hot water three 214-inch flow pipes 

 and twelve 2-inch returns be used. 



BOILER ABOVE GROUND LEVEL. 



Will you kindly give us some in- 

 foimation with reference to the heat- 

 ing of our greenhouse? The house is 

 3(1x100. The side walls are six feet 

 high and contain three feet of glass. 

 The height to the ridge is fourteen 

 feet six inches. The boiler is 100 horse- 

 power. The bottom of the boiler is 

 from twelve to fourteen inches above 

 the floor level of the greenhouse. I 

 should like to heat the house with hot 

 water, if possible, and use a great 

 many 2-inch pipes. The house will be 

 used mostly for carnations and gera- 

 niums and T wish to carry a temp<?ra- 

 ture of about 52 degrees, in this Ohio 

 climate. Kindly let us know what size 

 of pipe should be run from the boiler 

 to the greenhouse, what size is needed 

 for the return pipe and how many 

 strings of pipe are needed for the house, 

 in order to make it a practical sys- 

 tem. How would you advise us to 

 distribute the pipes? There will be 

 three low beds, on the ground, and two 

 benches on the north side, one to be 

 used as a propagating bench. The 

 greenhouse runs east and west and the 

 boiler house is at the northwest corner.

For the main flow and return, 4-inch 

 pipes would answer. The problem 

 would be simplified if the bottom of 

 the boiler were below rather than above 

 the level of the floor. The best re- 

 sults would be secured if the 4-inch 

 flow pipe could be carried under the 

 ridge to the farther end of the house, 

 but it should be supported upon posts. 

 If there are purlin posts, two lines of 



WHEN YOU BUY-OET A KROCSCHELL 

 'THE BOILER OF UNEQUALED FUEL ECONOMY' 



You will never be disappointed with a KROESCHELL Boiler. 

 Read what others say who have used different kinds: 



Get the Kroeschell First 



Several years ago Mr. Ponting corresponded with us In regard to 

 the Kroeschell Hot Water Boiler, but was persuaded to install two 

 sectional cast Iron boilers which were claimed to be superior to the 

 Kroeschell. 



In the meantime we placed a number of Kroeschell Boilers in the 

 Immediate vicinity of Mr. Ponting, and he could not help but notice 

 their great efficiency, and last year, while at the convention, he placed 

 his order for his first Kroeschell. The following letter speaks for 

 itself: 



"We like the KroeHrhell Boiler very much. It Kives entire satis- 

 faction, and it Ih ho easy to Are. I will trade you the two cast iron 

 sectional boilers for another like the Kroeschell I have."

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 fire same only twice a night. The following 

 letter speaks for Itself: 



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

 weather. Your Kroeschell Boiler is the best I ever had. Before I h«ard about your 

 boiler I had four cast iron boilers, and I would not part with the Kroeschell for a 

 hundred cast iron boilers now." (Signed) CHARLES SCHULTZ.

Kroeschell Replaces 2 Cast Iron Boilers 



The Marysville Floral Co., of Marysvllle, O., installed a Xo. 4 

 Kroeschell Boiler in 1905. Previous to this time they used cast iron 

 boilers. The following letter speaks for itself: 



"Has the Kroeschell given entire satisfaction? YES! We had 

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

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

 the expense that we have been put to was a smoke dome."

Kroeschell Replaces Cast Iron 



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

 iron boilers. Last season this firm installed their first Kroeschell, a Xo. C. which i> 

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

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

 write as follows: 



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

 ever had. For years we have flred many diflTerent 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 iMiiler proposition.. \\'<' 



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



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



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