Creenhouse Heating. 



SuBSCEiBERS are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, wd 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



A EANGE OF EIGHT HOUSES. 



Will you oblige me by telling me how 

 to pipe for steam my range of eight 

 greenhouses? Please state, also, what 

 size of boiler will be needed. Six of the 

 houses run east and west; they are each 

 18x100 and four feet high to the gutter. 

 The other two houses, which are new 

 and modern, run north and south; they 

 are each 25x125 and seven feet high to 

 the gutter. There is glass in the west 

 wall and in both ends. 



N. P. & F. C— 111. 



The temperature to be maintained is 

 not stated, and without knowing this we 

 are not able to give a definite reply. If 

 a temperature of 60 degrees will answer, 

 we would use in each of the 18-foot 

 houses one 2-inch flow pipe, carried un- 

 der the ridge, and eight 1 14-inch re- 

 turns, placing part of them on each wall 

 and the others under the benches. For 

 50 degrees use only six returns. 



In the new houses, for 60 degrees, use 

 three 1%-inch flow pipes, placing one 

 upon each plate and the other under the 

 ridge, with eight 1^4 -inch returns upon 

 the walls or under the benches. If a 

 temperature of only 50 degrees is de- 

 sired in any of these houses, omit two 

 of the returns. The house in which 

 there is glass in the side wall will re- 

 quire an additional return on that wall 

 for each two feet of glass. We would 

 use a 50-horsepower boiler for 60 de- 

 grees. For 50 degrees a 40-hor8epower 

 boiler will suffice. 



HOT WATER TOE TWO HOUSES. 



I intend to build two greenhouses, 

 running east and west, and I wish to get 

 your idea of how to pipe them for hot 

 water to maintain a temperature of 55 

 to 60 degrees in zero weather. The 

 north house will be 10x60 and twelve 

 feet high to the ridge. The north wall 

 will contain two feet of glass above 

 three and one-half feet of boards. The 

 ends, except the lower three and one- 

 half feet of boards, will be of glass and

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

 by Eroeschell specifications— the best that money and brains can produce. 

 ^Workmanship— the kind that is an inspiration to all other boiler makers. 

 Boiler efficiency— determined by actual tests underworking conditions. Boiler 

 ratings— honest and true blue— guaranteed actual working capacities.

Probably you have wondered why the Kroeschell Greenhouse Boiler is not sold by 

 any of the greenhouse construction companies. In justice to all concerned we feel 

 it is our duty to state that the Kroeschell Boiler is never sold by any one but— 

 THE KROESCHELL BROS. CO.— We have no agents, and as our prices are based 

 on sales direct from factory to user, we do not quote any one dealing in boilers 

 special resale prices. Our stand in this matter has brought out a lot of competi- 

 tion; nevertheless, the great efficiency of the Kroeschell Greenhouse Boiler 

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

 house Boiler is heating more glass than any other make.
