sired. This can be secured by running 

 a 2 14 -inch main under the ridge to the 

 farther end of the house and with it 

 supplying twenty 1^4 -inch returns. If 

 a temperature of 50 degrees will answer, 

 the flow pipe may be 2i^-ineh and only 

 fourteen 114 -inch returns will be 

 needed. 



There are several excellent steam 

 traps on the market and any of those 

 advertised in The Review will give sat- 

 isfaction. Without knowing just how 

 the benches are arranged, no definite 

 plan for locating the returns can be 

 suggested, but about one-third of them 

 may be placed on each wall and the re- 

 mainder under the benches. 



YOKma TWO BOILEBS. 



Will you kindly give me some infor- 

 mation on the connecting of two hori- 

 zontal steam boilers, each of which has 

 a capacity of 100 horse-power? I wish 

 to be able to use them either as a bat- 

 tery or separately. I should like to 

 know whether they must be placed on 

 the same level and how the water con- 

 nection should be made so as to keep 

 the water line the same. On account of 

 limited space, I want to have them rest 

 on the same central wall. Can that be 

 done? We are using a return trap. 

 Would it answer for both boilers? 



H. F. C. 



If the boilers are of similar construc- 

 tion they can be set at the same height, 

 but if one is of greater diameter than 

 the other care should be taken to set 

 them so that the desired water levels in 

 the two boilers will have the same ele- 

 vation. There is no reason why a' sin- 

 gle wall will not answer between the 

 boilers. The boilers can then be yoked 

 together so that either one or both can 

 be used. One trap will serve for the 

 two boilers, using it to return the water 

 to a feed tank with which the boilers- 

 should be connected. . » . 



PIPING A PARTITIONED HOUSE. 



Will you kindly inform me how to 

 heat a greenhouse of the following de- 

 scription with hot water? The hoyse is 

 three-quarter-span and is 18x70. It is 

 twelve feet high to the ridge and has a 

 4-foot wall on the south and a 6-foot 

 wall or the north. The office is at the 

 east end and the boiler is at the west 

 end. There is a glass partition through 

 the center and I wish to heat the east 

 end to 60 degrees and the west end to 

 50 degrees. The office is not heated 

 from the greenhouse. Kindly give the 

 size and number of pipes and their ar- 

 rangement. As it will be extremely in- 

 convenient to place the boiler in a cel- 

 lar, can I place it on a level and use a 

 mercury generator? If so, please esti- 

 mate the piping accordingly. In this 

 part of North Dakota the outside tem- 

 perature sometimes drops to 40 degrees 

 below zei*©. M. B. 



To heat the house described, under 

 the severe conditions, it will be well to 

 run a 3-inch pipe about two feet below 

 the ridge, and with a slight fall, to the 

 farther end of the house, and connect 

 it with eight 2-inch pipes to be carried 

 uhder the middle benches back to the 

 boiler. Then run a 2-ihch flow pipe on 

 each wall plate and carry back three 2- 

 inch returns on each wall, or under each 

 s\de bench, as far as, the jmrtition, from 

 which,point a 2-irich return on each side 

 of the house should- fun to 'the boiler. 



THE MAN WHO NEEDS A BOriER 



The customer's Interest first — Is the basis of the Kroeschell standard, and this prin- 

 ciple makes the Kroeschell policy the most liberal of all In the greenhouse boiler 

 business. 



The great variety of boilers that we make places us in a commanding position. We 

 make every type of boiler that Is used, from the smallest house heater to the largest 

 water tube steam boiler (600 horsepower). For the above reason we can furnish the 

 most efllcient boiler unit in every case. 



It is the Kroeschell principle to supply only that type of boiler which is best suited 

 to the conditions and under no circumstances do we take any other stand. . . . , 



WHEN YOU BUY- GET A KROESCHELL 

 ««THE BOILER OF UNEQUALED FUEL ECONOMY" 



Kvery boiler made at our works is of the highest standard. Material — governed 

 by Kroeschell specifications — the best that money and brains can produce. Workman- 

 ship — the kind that is an Inspiration to all other boiler makers. Boiler efl[lciency — 

 determined by tactual test under working conditions. Boiler ratings — honest and true 

 blue — guarantee actual working capacities. 



Probably you havo wondorod why the Krooscholl Greonhous* Boiler Is not sold by 

 any off the KfAenhoueo construction companies. In lustice to all concerned we 

 ffeel It Is our duty to state that the Kroeschell Bolier Is never sold by any one 

 but-Tho KROESCHELL BROS. CO.-Wo have no asents, and as our prices are 

 based on sales direct from factory to user, we do not quote anyone deallns In 

 boilers special resale prices. Our stand In this matter has brousht out a lot off 

 competition; nevertheless, the xrcat efficiency of the Kreescheli Greenhouse 

 Boiler cannot be disputed, and in spite of the keen competition the Kroeschell 

 Greenhouse Bolier Is heatins more (lass than any other make-" DO NOT GET 

 CHEATED OUT OF THE KROESCHELL BUT PLACE VOUR ORDER DIRECT AT ONCE." 



Get the Kroeschell Tint 



Several years ago Mr. Pontlng 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. Pontlng. and he could not help but notic» 

 their great eflSclency, and last year, while at the convention, he 

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

 for Itself: 



"We like the Kroeschell Boiler very much. It gives entire satis- 

 faction, and It Is so easy to Are. I will trade you the two ca«t iron 

 ftectional boilers for another like the Kroeschell I have." 

 July 16. 1913. Cleveland, Ohio. (Signed) FRED PONTING. 



Kroeschell Replaces Cast Iron 



In 1912 our cast iron sectional boiler 

 cracked in one section and we ordered 

 a No. 3V4 Kroeschell Boiler by tele- 

 graph. This boiler is heating 10,200 

 sq. ft. of glass, besides the oflilce and 

 potting shed, and you will note this 

 is 1,200 ft. more than its rating. We 

 have no trouble to maintain proper 

 temperatures at any time and the 

 boiler has given perfect satisfaction. 



With the Kroeschell we have added 

 one more house, but have not used any 

 more coal than with the cast iron 

 boiler and 3,000 ft. less to heat. One 

 cast iron break-down was enough for 

 us, for we have found it pays to get 

 the best — the Kroeschell. 



(Signed) MICHLER BROS. CO.

Kroeschell Replaces 3 Cast Iron Boilers 



The No. 6 Kroeschell which we pur- 

 chased some years ago is heating 18,- 

 000 sq. ft. of glass, and we should 

 Judge that it would take care of 5,000 

 or 6,000 ft. more easily. 



Our houses require a temperature of 

 50 to 62 degrees at night, and we cer- 

 tainly do not have the least trouble to 

 keep temperatures In the coldest 

 weather. We do not have to fire our 

 boiler as often as our brother florists 

 who are using different makes. The 

 Kroeschell has replaced three cast iron 

 sectional boilers, and it certainly has 

 given entire satisfaction. 



It only takes a few words to ex- 

 press the good quality of your boilers 

 and they are as follows: "Of all firms 

 handling boilers and advertising them 

 truthfully, the party buying a boiler 

 would have to get the Kroeschell, as 

 you are certainly advertising nothing 

 but facts."
