HEAT FOR PROPAGATING HOUSE. 



Kindly tell me how much pipe is re- 

 quired for a propagating house 12x90 

 feet. This propagating house is inclosed 

 by other buildings on all four sides, and 

 the only exposure is the roof. The house 

 has a single-span roof and the height is 

 five feet at the lowest point and eight 

 feet at the highest point. Tliere are two 

 beds, one five feet in width and the other 

 three feet in width. How much 4-inch 

 pipe would be required to heat this with 

 hot water in New York climate? 



J. Y. 



With a propagating house so thorough- 

 ly protected as the one described, it should 

 be practicable to heat it sufficiently for 

 roses and other high-temperature stock 

 by the use of five lines of -^--inch pipe. If 

 three of these can be placed under the 

 wide bench and two under the narrow 

 one, I think the service will prove satis- 

 factory. If, for any reason, more in- 

 tense l3ottom heat is desired in any por- 

 tion of the benches, this can bo secured 

 by inclosing the bench for the space de- 

 sired to be carried with increased bot- 

 tom heat. L. C. C. 



PIPING IN MICHIGAN. 



I wish to know how much radiation it 

 will take to heat my house, 16x50 feet, 

 with side wall^ four feet and a half high, 

 and also how many runs of 2-iuch pipe it 

 will take. There are three benches, the 

 center one six feet wide. I am going to 



put the boiler in my basement, which is 

 seven feet and a half deep. The distance 

 from the boiler to the greenhouse is 

 about forty feet, twenty feet of tihat dis- 

 tance being in the basement. The chim- 

 ney has an S^^s-inch square opening and 

 is forty feet high from the basement, 

 which, I think, will give plenty of draft. 

 I wish to get a boiler rated at 1,000 — a 

 Wilks boiler, I think. F. L. T. 



Your house, to maintain a temperature 

 of 65 to 70 degrees, will require 350 

 square feet of radiation. To provide this 

 in the house with 2-inch pipe, 560 lineal 

 feet of pipe will be required. If eleven 

 runs of 2-inch pipe are installed an(J ar- 

 ranged in two or three coils, one pipe in 

 each coil serving as a flow and the others 

 as returns, there will be no difficulty in 

 heating the house with a boiler of the 

 size suggested, provided the pipes are 

 properly installed and graded. L. C. C. 



HEAT FOR BEDDING STOCK. 



I am about ready to pipe a greenhouse 

 20x50 feet. It measures twelve feet to 

 the ridge, and the side walls, which are 

 concrete, are three feet high. The house 

 runs north and south. A shed 18x19 feet 

 is attached to the south end; the north 

 end is closed up. The house is fully ex- 

 posed on all sides. Kindly give your ad- 

 vice as to how to arrange the heating 

 system. The boiler has two 3-inch open- 

 ings on top for flow pipes and four 

 openings for return pipes. The boiler 

 stands about five feet below the level of 

 the house, which has a fall of six inches 

 from north to south. The pipes will be 

 under the benches at the east and west 

 sides. I shall have to run a flow pipe

from the boiler, in the west corner, over 

 to the east corner, a distance of sixteen 

 feet. Can I divide that pipe in the cen- 

 ter and run a branch five or six feet 

 high along the supports under the ridge 

 to the end of the center bench and down 

 to the floor to the returns? Can I not 

 place the expansion tank at the north 

 end of the house, instead of over the 

 boiler, at the south end? The tank has
