(greenhouse Heating. 



Subscribers 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 Eeview to make 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. 



MOSTLY FOB PROPAQATINO. 



I have a house 36x75, which I have 

 been heating to a temperature of 52 

 degrees without forcing the boiler. I 

 wish to build another house, 15x30, 

 placing it so it will run parallel with 

 the present house, only it will be six 

 feet away and the east end of it will 

 join the boiler room on the west. I 

 wish to heat the new house to 60 de- 

 grees in zero weather. Please tell me 

 how to pipe it. It will be used for 

 propagating geraniums and coleus, for 

 starting vegetable plants, and for ferns. 

 It will contain two side benches and 

 one center bench. The walls will be 

 entirely of concrete and will be five 

 feet high. . The pipe to be used is all 

 2-inch and a hot water system is used. 

 Will gate valves be needed in each 

 house, and how many, to keep the right 

 temperature! F. C. F. — Ind. 



To heat the proposed house, 15x30, 

 to 60 degrees, we would run a 2% -inch 

 flow pipe upon each plate and connect 

 each of these flow pipes at the farther 

 end of the house with a coil of four 

 2-ineh returns, placed under the side 

 benches. With a downhill system of 

 piping, there will be no occasion for 

 any air valves if the highest point in 

 each flow pipe is connected with the 

 expansion tank. Without knowing how 

 the pipes in the present house are ar- 

 ranged, we cannot advise definitely re- 

 garding the number and location of the 

 gate valves. It is generally a good 

 plan to have either a gate or an angle 

 valve upon each of the flows. Unless 

 a break in the system occurs, there is 

 seldom any occasion for valves on the 

 returns. 



WOULD OVERTAX THE FLOW. 



We have a greenhouse 32x100, 

 heated with hot water on the downhill 

 system. The piping consists of one 

 flow and six returns on each side, and 

 four flows and four returns in the cen- 

 ter. This piping heats the house with 

 ease. We should like to add a house

20x50, at one side, and heat it by plac- 

 ing returns in it and connecting the 

 returns with one of the side flows in 

 the present house. We want a temper- 

 ature of 60 degrees in the new house, 

 in zero weather. Can this plan be car- 

 ried out and how many 2-inch returns 

 will be needed! The side flows are 

 214-inch. J. A. F. & S.— O. 



The present radiation is well planned 

 so far as the side coils are concerned, 

 and we would not care to make the 

 change just as suggested. The flow 

 pipes now supplying the side coils are 

 providing for 450 square feet of radiat- 

 ing surface, which is the maximum 

 amount that can be handled to advan- 

 tage by a 214 -inch flow pipe. The new 

 house should have about 400 square 

 feet of radiation and for this two sepa- 

 rate 2V^-inch flow pipes should be pro- 

 vided. 



, If there is no glass in the side walls 

 of the house 32x100, two of the flow 

 pipes in the middle of the house can be 

 spared and it is suggested that the 

 returns to which they are now con- 

 nected be joined to the other two flow 

 pipes. If these flow pipes are carried 

 overhead, the two spare ones can be 

 cut off at a point even with the end

 Each of these flow pipes may be used 

 to supply a coil of 2-inch pipes, located 

 on the walls. To give a temperature 

 of 60 degrees with hot water, a house 

 20x50, with one wall exposed but hav- 

 ing no glass in the wall, will require 

 seven 2-inch returns in the coil on the 

 outside wall and six returns on the 

 inner wall.
