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. 



JOINING RETURNS TO BOILER. 



I wish to get some information as to 

 the proper method of connecting return 

 pipes to an ordinary return-tube, hori- 

 zontal boiler, rated at about fifty horse- 

 power and to be used for hot water heat- 

 ing. Of course, the flows should proceed 

 from the dome, but where should the 

 return openings be made? The boiler 

 is 14x44 inches, and has forty-six 3-inch 

 tubes. Would two 5-inch openings be 

 better than one 7-inch? I expect to use 

 the boiler under moderate pressure, ten 

 to twenty pounds. I shall appreciate 

 an early reply* S. C. W. — Pa. 



So far as the efficiency secured is con- 

 cerned, it really makes little difference 

 where the returns are connected. Two 

 5-inch returns will work well with a 

 7-inch main flow and we would connect 

 them where it will be most convenient. 

 Connection may be made on the top of 

 the shell if the boiler is well below the 

 lowest returns. In that case, one of the 

 returns could be connected two feet 

 from each end. Another way would be 

 to enter the side of the shell, connecting 

 the two returns on opposite sides of the 

 boiler, preferably near one end. 



SOME OF THE PIPES ARE COLD. 



Will you kindly help me out of a lieat- 

 ing trouble? A year or so ago I built a 

 salesroom in front of my greenhouse, 

 and placed in the salesroom a radiator 

 and four 1^/1. -inch returns. The four 

 1%-inch returns are fed by a 2-inch 

 flow, which also feeds three 2-inch re- 

 turns on the side wall of the greeuliouse. 

 The 2-inch flow, in turn, is fed by a 3- 

 inch main. Tho radiator is not fed by 

 this line at all, but by another 3-inch 

 pipe. The return from the radiator and 

 from the li/^-inch coil runs under the 

 2-inch returns to the rear of the green- 

 house and empties into the 2-inch return 

 tnrough a Y. 



Since installing the pipes in the sales- 

 room I have been unable to get any heat 

 from the 2-inch returns on the side wall 

 in the greenhouse, and I shall be thank- 

 ful if you can tell me how to change 

 the piping so these 2-inch lines will 

 heat. Hot water is used for heating. I 

 enclose a sketch of the piping. 



W. E. P.— O. 



The sketch shows that return bends 

 have been used in making up the coils, 

 and such an arrangement tends to hin- 

 der the circulation as compared with a 

 coil built with headers. It is also pos- 

 sible that the alignment of the pipes in 

 the 2-inoh coil is such as to ])ermit the 

 pocketing of the air. If the trouble is 

 not due to such wrong alignment, we 

 would suggest that a coil built up with 

 headers be constructed from the 2-inch 

 pipes, and that another be' constructed 

 in the sjilesroom from the lVl>-inch pipes, 

 provided a good circulation is not se-

PIPING IN A MILD CLIMATE. 



Will you please inform me as to the 

 best method of heating my houses for 

 carnations, by the hot water system? I 

 have two connected greenhouses, with a 

 12-inch gutter between them. They are 

 14x16, running north and south. The 

 north end is boarded up and contains 

 one door, 3x6 feet, with a ventilator 

 18x24 inches over the door. The south 

 end is all glass except the door and two 

 feet of boards just above the ground. 

 The east and west walls are four feet 

 six inches high and contain two feet of 

 boards and two feet six inches of glass.
