Greenhouse Heating. 



■^^"^■" ■■ ' — - ■■■■■■» 



Sdbsgeubers 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 Beview to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, tiie best for the trade to Duy, 

 and each article the best in the special 

 field of its adaptation. 



DEPENDS Olt STYLE OF BEDS. 



I am planning to erect a small green- 

 house and should like to get the advice 

 of The Eeview's Heating Department 

 about the piping of it. The house will 

 be 18x36, with 6-foot side walls, each 

 containing three feet of glass. It will 

 be an even-span house, running east and 

 west, with a boiler room and potting 

 shed across the west end. I propose to 

 use hot water and shall want a tempera- 

 ture of 70 degrees in zero weather. 

 What size and arrangement of pipes 

 will be best for this house? How far 

 below the level of the greenhouse floor 

 should the boiler be placed, for best 

 results? H. M, D. — Tenn. 



To heat a greenhouse 18x36, with 

 three feet of glass in the side walls, to 

 70 degrees in zero weather, we would 

 use three 2i^-inch flow pip^, placing 

 one upon each plate and the other two 

 feet below the ridge. For the return 

 coils place three 2-inch pipes on each 

 side wall and five under the middle 

 bench. In case solid beds are used, it 

 would be possible to heat the house 

 with a 2% -inch flow pipe upon each 

 plate and with six 2-inch returns on 

 each wall. 



While a fairly good circulation may 

 be secured if the top of the boiler is 

 even with the floor of the greenhouse, 

 we would prefer to place the boiler 

 two feet lower. 



"PIPED WITHOUT ANY SYSTEM." 



We are repiping three houses which 

 we recently purchased, and which are 

 now piped without any system at all. 

 The houses are each 28^^x100. We 

 have a 35-horsepower steam boiler. One 

 house is used for carnations, one for 

 chrysanthemums and geraniums and 

 the other for ferns. I am enclosing a 

 rough sketch of tlio piping, so you can 

 gather some idea of its present arrange- 

 ment. 



We had planned to run one 2-inch 

 flow through the gable of each house 

 and return with two 1-inch pipes under 

 each of the four benches. These flows 

 would leave a 4-incli main at the west 

 end and run to the east end. We should 

 also like to place a l^/^-inch or li4-inch 

 return under each gutter, to serve in 

 case of snow. Will this be enough pip- 

 ing in the mum and carnation houses, 

 where we want a temperature of 55 de- 

 grees at night? In the north house, 

 which will be used for ferns, we planned 

 to place two 2-inch flows on the pur- 

 lins, with the returns the same as in the 

 other two houses. Will it be satisfac- 

 tory to run a coil on the east end and 

 above each door? The houses are lo- 

 cated on a small hill and are entirelv 

 without protection. T. F. C— 111. ^

Remarkable Commercial Records 



The past year has developed unheard-of commercial records for 

 the business interests of this country. 



U. S, exports have reached the enormous sum of $4,000,000,000. 



The bank clearings of our country were $260,102,653,054. 



The tonnage in steel assumed the astounding figure of 40,000,000 

 (forty million) tons. 



The year's earnings in freight and transportation of the railroads 

 ran into billions. 



HORTICULTURALLY speaking, 1916 also made remarkable 

 history. 



Cut Flowers and ) $70,000,000 to $72,000,000 (accord- 



Greenhouse Products j ing to the best available figures). 



These figures, we hope, will leave a generous and well deserved 

 profit for our numerous florist friends. 



Our company takes pride in announcing that the year 1916 goes 

 on record as the world's highest mark in the sales of greenhouse 

 boilers. During the year of 1916 we sold direct from factory to user 

 the following boilers for greenhouse heating: 



Kroeschell Greenhouse Hot Water Boilers 1,639,500 sq. ft. glass 



Kroeschell Tubeless Hot Water Boilers 104,860 sq. ft. glass 



Kroeschell Tubeless Steam Boilers 65,400 sq. ft. glass 



Kroeschell Water Tube Steam Boilers 203,200 sq. ft. glass 



Kroeschell High Pressure Steam Boilers 1,003,336 sq. ft. glass 



TOTAL 3,016,286 sq. ft. glass
