Creenhouse Heating. 



SuBSCKiBEBS 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. 



FOB LOW-PBESSXTBE STEAM. 



Will you kindly tell me how my two 

 greenhouses should be piped for low- 

 pressure steam? The larger house, 28x 

 125, runs north and south. The side 

 walls are six feet high and contain three 

 feet of concrete and three feet of glass. 

 The North end is boarded; the south end 

 adjoins the boiler shed. In this house I 

 wish to maintain a temperature of 50 

 to 55 degrees. 



Fifteen feet from the north end of the 

 house described, and on ground about 

 three feet higher, is the other house, 

 which is 22x60, running east and west. 

 It is nine feet high to the ridge. The 

 south wall is four feet high and is all 

 glass. The north wall is three feet high 

 and consists of one foot of boarding 

 above two feet of concrete. The west 

 end is boarded; the east end is all glass. 

 I want a temperature of 60 to 65 degrees 

 in this house, in zero weather, I have 

 nearly enough 2-inch pipe for the re- 

 turns. I also have some 2%-inch pipe 

 and valves which I wish to use in the 

 flows. E. F. C— Pa. 



For heating a greenhouse 28x125, with 

 three feet of glass in the side walls, to 

 55 degrees in zero weather, we would 

 run a 2i4-inch flow about three feet be- 

 low the ridge and connect it at the 

 farther end of the house with eight 2- 

 inch returns. All of these may be on 

 the walls, or four of the returns may be 

 distributed under the benches. Wo 

 would prefer, however, to use twelve 

 114-iiich pipes as returns.

For the house 22x60, with four feet of 

 glass in one wall, to be heated to 65 de- 

 grees, we would also use eight 2-inch 

 or twelve li/4-inch returns, and either a 

 2%-inch or a 2-inch flow pipe. Since 

 there is no glass in the north wall, we 

 would use one less return on that side. 

 The main returns in each house should 

 be 2-inch. 



Automatic air valves will be required 

 near the lower end of each coil, and 

 there should be gate valves at both ends 

 of one-half of the returns, as well as on 

 the main flow and return pipes. 



CANNOT GET ENOUGH HEAT. 



I am writing you for information 

 concerning the heating of my green- 

 houses, which are already piped for hot 

 water. The boiler is a Williamson un- 

 derfeed, 34 O. W. We are trying to heat 

 two houses, 32x90 and 21x60. They are 

 piped for 1,800 feet of radiation. The 

 pipe in the coils is 1%-inch. There are 

 two 3-inch outlet pipes for the larger 

 house; these are reduced to 2^-inch 

 and 2-inch where they empty into the 

 coils. The coils consist of eight pipes 

 on each side of the house, made up in. 

 two sections, and eight pipes under the 

 center bench. Two 2-inch main returns 

 run to the basement and enter a 3-inch 

 pipe just outside the boiler. The outlet 

 and inlet of the boiler are made for 

 5-inch pipes, but the steamfitter reduced

 the feed pipes is about ten feet above 

 the floor of the basement. 



The draft is good. The chimney, 

 which is of brick and twenty-five feet 

 high, gets so hot that it was necessary 

 to wrap it with asbestos to protect the 

 floor and roof at the outlet. Yet we 

 cannot get suflScient heat for the two 

 iouses. The greatest heat indicated by 

 the thermometer on the boiler is 160 

 degrees, with full draft, a«MF*s soon as 

 the draft is closed the heat falls rapidly,

 small, or is the piping improperly ar-
