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 Review 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. 



A PARTITIONED GREENHOUSE. 



I am building a greenhouse 31x85 and 

 twelve feet to the ridge. The house 

 will be used for oarnations and other 

 stock, except twenty feet next to the 

 boiler, which will be used for roses and 

 will be cut off by a i)artition from the 

 rest of the house. My iilea is to use 

 two 2*/^-inch flows on the purlins and 

 one 3-inch flow under the ridge, with 

 three coils of 2-inch pipe for returns. 

 How many returns should be used in 

 this West Virginia climate, and what 

 would be the best arrangement of the 

 return pipes? I shall use raised benches 

 in the carnation house and on the side 

 of the rose house; in the center of the 

 rose house there will be solid beds. The 

 house runs east and west, with the 

 boiler at the east end. The side walls 

 will be three feet high and will contain 

 no glass. H. E. H. 



Good results could be obtained with 

 the flow pipes as proposed, although it 

 would be fully as well to make all the 

 flows 2y2-inch and in some ways this 

 would be better. The carnation house 

 can be heated by using ten 2-inch re- 

 turns, and if these can be carried back 

 through the rose house it will only be 

 necessary to place two additional re- 

 turns oii each of the walls to furnish 

 the extra heat required. These can be 

 fed by a 2-inch flow taken off from the 

 wall flows on each side, at the west end

of the rose house. In the carnation 

 house two or three of the returns can 

 be on each of the walls or under the 

 side benches, and the others can be 

 under the other benches. As solid beds 

 are to be used in the center of the rose 

 house, it will be necessary to carry the 

 returns from the carnation house on the 

 sides of the beds.
