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 l3uy, 

 and each article the best in the special 

 field of its adaptation. 



RELATIVE NUMBER OF FLOWS. 



Seeing so many good things in The 

 Review in regard to heating green- 

 houses, I thought I would ask a ques- 

 tion with reference to my house, which 

 is 16x100. At present the house is 

 piped with three 2-inch flows and three 

 2-inch returns. In other words, I in- 

 stalled one return for each flow, think- 

 ing that the water would return to the 

 boiler much warmer than if only one 

 flow were used to serve the returns. 

 But, after reading your advice, I see 

 you suggest the use of one flow for sev- 

 eral returns. I may say I have not had 

 satisfactory results, but I have blamed 

 the position of the boiler, as it was not 

 low enough; so I lowered it this fall. 

 I am located in New York state. 



B. F. S. 



There is no particular objection to 

 using only one return for each flow 

 pipe, but, on the other hand, experience 

 has shown that, within certain limits, 

 it is possible to use several returns 

 upon one flow pipe. In the case of a 

 house 100 feet in length, however, I 

 would not, under ordinary conditions,

use more than two 2-inch returns for 

 a 2-inch flow. 



It has also been found that the cir- 

 culation can be improved by carrying 

 the flow pipes overhead, or at least upon 

 the eave plates, especially when the 

 boiler stands at or near the surface of 

 the ground. For this reason I recom- 

 mend the use of 2%-inch pipe for the 

 flow pipes in houses 100 feet in length 

 or longer, using only as many flows 

 as are needed to supply the returns. 

 Thus, in a house 16x100 feet, without 

 glass in the side walls, I would use two 

 2^^-inch flow pipes overhead, and six 

 2-inch pipes on the walls, or under the

benches, for 50 degrees, and two flows 

 and eight returns for 60 degrees. 



In case 2-inch pipes are used for both 

 flows and returns, with a return for 

 each flow, ten pipes should be used for 

 50 degrees and twelve for 60 degrees. 

 With such piping, however, if the flow 

 pipes were overhead the number would 

 not only be objectionable but the pro-
