Greenhouse Heating. 



Prices on coal contracts running 

 tlirough the year are being well main- 

 tained. 



A TENDENCY is apparent this season 

 among the soft coal producers to curtail 

 production, keeping tiie coal in the 

 ground whenever tliey cannot get a price 

 that leaves a margin of profit. 



SUBSCRIBEKS are invited to write tiie 

 Editor of this Department witli regard to 

 any details of greenhouse lieating tliat 

 are not understood. But please do not 

 ask The Keview to nuike a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



STEAM FOR ONE HOUSE. 



I am building a greenhouse 2()x60, 

 ten feet high to the ridge and six feet 

 to the eaves. The north wall is built 

 of cement and lumber. The south side 

 and the ends have two feet of cement 

 wall and the rest is glass. Kindly tell 

 me how to heat the house with steam, 

 from a cast-iron boiler, stating the num- 

 ber and size of pipes needetl. J should 

 like to run a How pipe from the boiler, 

 tapping it at each bench and running 

 a flow and return either under the 

 bench, or on the side if 1 use solid 

 beds. Is this jiractical? If so, please 

 give the size of all pipes needed. Will 

 the four flows and four returns give the

heat needed? We often have outside 

 temperatures of 15 to 20 degrees below 

 zero for a day or two. Our location is 

 west central Iowa. If my idea is not 

 practical, kindly suggest the cheapest 

 plan. E. S. F. 



The temiierature desired is not stated, 

 but if the house is to be used for roses 

 or other crops which require a night 

 temperature of (50 degrees, a consider- 

 able increase will be necessary in the 

 radiation mentioned. Instead of run- 

 ning a flow and return pipe under each 

 of the four benches, it is suggested that 

 a 2-inch flow be run overhead, about 

 two feet below the ridge, and that at 

 the end of the house two IVi-inch re- 

 turns be run in each direction and car- 

 ried back to the boiler on the plates. 

 In addition to this, there should be two 

 IVi-inch returns under each of the four 

 benches. These should be connected 

 with a ]^/> inch pipe, which .should be 

 taken off and run in each direction 

 from the overhead flow, at a point over 

 the ends of the benches. 



In case 50 degrees or a little less will 

 answer in the coldest weather, it can be 

 secured by means of eight 1^-inch re- 

 turns, in addition to the 2-inch over- 

 head flow pipe. If solid beds are used, 

 the returns can be on the walls, or a 

 part of them can be in the walks. 



FROM HOT WATER TO STEAM. 



W^iil you kindly let your heating c-x 

 l»ert pass on the following question? 

 My house is 34x70 and sixteen feet 

 high to the ridge, with two feet of 

 glass in the east wall and a solid con- 

 crete wall on the west side. The house 

 runs north and south. The south end 

 is glass; the north end abuts agaiust 

 my dwelling. There are six rooms in 

 the dwelling, all heated by a hot water 

 boiler situated in the basement. A 

 3-Jnch feed pipe, running under the 

 ridge, feeds nine 2-inch returns under 

 three center benches. One 2-inch tVcd 

 on the purlin posts feeds five 2-in<h 

 returns on the east wall; two 2-inch 

 feeds supply 2-inch returns on the west

Fires Once Every Four to Six Hours 

 In Coldest Weather 



I am fully satisfied with your No. 2 Kroeschell boiler. I have had differ- 

 ent kinds of saddle and tubular boilers, but none of them give such satisfac- 

 tion as yours. I have 7000 sq. ft. of glass, and your boiler would take care of 

 8000 sq. ft. of glass. I maintain 50<» temperature and fire every four to 

 'six hours in cold weather; otherwise from six to eight hours.
