KEATING^ VEGETABLE HOUSE. 



I have a house 33x141 feet, running 

 east and west; it is fourteen feet to the 

 ridge and the walla are six feet high, 

 with four feet of glass. I expect to heat 

 it with hot water, using two 4-inch 

 flows, one on each side on the purlin 

 posts, and four 4-inch returns, two on 

 each side. I shall have, an 85-horse- 

 power boiler located at the northeast 

 end of this house. There, are no other 

 jfaouses connecting. The house will be 

 used for growing vegetables and vege- 

 table plants. Will this plan provide 

 sufficient radiation? 



H. D. C— 111. 



With two 4-inch flow pipes and four 

 4-inch returns it would hardly be pos- 

 sible to maintain more than 40 degrees 

 in the house described, although, as the 

 boiler is several times al large as is 

 necessary, if the grate is as large in 

 proportion it would probably be pos- 

 sible to do somewhat better than this, 

 unless the temperature outside drops be- 

 low zero. However, it would be ad- 

 visable to put in six 4-inch returns. 



Far more economical results might be 

 expected with a boiler rated for 2,000 

 square feet of hot water radiation and 

 having a grate, area of about eight 

 square feet. It is necessary to have a 

 ■ larger boiler when 4-inch pipe is used 

 for the returns than when 2-inch re- 

 turns are installed. It would be better 

 to use five 2%-inch flow pipes and ten 

 2-inch returns, although twelve or thir- 

 teen would be required if 50 degrees 

 is desired.

PIPINa TO BESIDENCE. 



■ I am sending you a diagram of the 

 residence now built and of the green- 

 house that I intend to build as sbon as 

 the weather will permit. I should like 

 to know how to heat both residence and 

 greenhouse from one boiler. The resi- 

 dence is of frame construction, with 

 brick foundation and plastered interior. 

 The greenhouse will be 28x64 feet, with 

 concrete walls three feet above ground 

 and two feet of ghiss on the sides. 

 There will be a boiler room at the north 

 end and an ofi&ce, 16x16 feet, at the 

 south end. I plan to use solid beds, 

 with concrete walks sunk twelve inches 

 and beds raised twelve inches. Would 

 it Jbe advisable to run the pipes through 

 the bottom of the bedst How many 

 should there be and how large! Could 

 I run a main pipe two feet below the 

 ridge to the office and then drop it to 

 the floor and across to the residence, a 

 distance of sixteen feetf What size of 

 pipe would be required for this? Will 

 an ordinary steam boiler work for a hot 

 water heating system? If so, what 

 horsepower will it take to heat the resi- 

 dence and a greenhouse of about twice 

 the size of this one, since I may want to 

 build another one of about this size 

 later? T. L. G.— Tenn. 



The sketch shows the residence to be 

 32x60 feet, with eight rooms, averaging 

 about 16x16 feet each. There are some 

 fifteen windows and seven outside doors. 

 The sizes of the wndows and height of 

 the rooms are not shown, but probably 

 about 500 square feet of radiation will 

 be required for heating the residence

KROESCHELL BOILERS have no bulky, 

 soot-accumulating surfaces— you avoid the 

 disagreeable work and trouble indispensable 

 to cleaning boilers with complicated and 

 tortuous back and forth fire passages. 



The superiority of our boilers has resulted in the removal 

 and abolishment of hundreds of cast iron sectional boilers 

 -in every instance KROESCHELL BOILERS give more 

 heat with the same piping with less fuel.

Rose Range of Riverbank Greenhouses, Geneva, III. Charles McCauIey, Supt 



Heated by No. 15 Kroeschell Boiler, Kroeschell 2-inch Return Piping System and Kroeschell 

 Generator. Greenhouses each 28 feet by 200 feet. Garland Construction. 



The mains are arranged to take care of a future addition of 40,000 sq. ft. of elaas; 2-inch returns are 

 used throuuhout the entire range and each 2-ineh return line ia controlled b^ 1-incn gate valve (strictly a 

 Kroeschell feature), insuring perfect control. It is a gravity job; the circulation is perfect, reaching the ex- 

 treme ends of range in fifteen minutes. The Kroeschell Generator (the high speed gear for hot water beat- 

 ing) is also used for this system. 



"Your No. 15 Kroeschell Boiler heats our entire range. We maintain a temperature of 

 60 degrees in our greenhouses, and this" temperature is easily maintained, even in the very 

 coldest weather. Your boiler has given entire satisfaction. It is the best and quickest 

 heater I have ever used or seen. I have found the boiler very economical in the use of fuel 

 and labor, as it is not necessary to use the best coal, and any labor will do for a fireman. 

 The Kroeschell Piping System with Generator works like a charm. When I want to sulphur. 

 I can heat the water up to 230 to 240 degrees and I get the same results as from steam. See- 

 ing is believing— ail Growers are invited to call. Any further information concerning boiler 

 and piping system will be gladly given. We had a large number of florists at our place 

 recently, and they all thought we had the finest equipped plant in the business."
