PlflNG IN OrtlO. 



My greenhouse is 12x60, and seven 

 feet and a half high to the ridge. The 

 boiler will be placed in a cellar adjoin- 

 ing the north end. The cellar is 12x12, 

 with a workroom above it. I expected to 

 get a Wilks boiler, 20x36, and to run 

 a 2-inch flow from the boiler along the 

 ridge, returning with twelve 1^4 -inch 

 pipes, six under each bench. The expan- 

 sion tank would be ten feet above the 

 boiler, in the upper room. The house is 

 intended for a general line of plants. 

 Will the proposed piping be sufficient to 

 heat to 60 degrees in zero wfeather? 



A. O. N. 



Yes, the piping you have planned 

 should give you a temperature of 60 to 

 65 degrees during severe weather. Eun 

 the flow pipe from the boiler under the 

 ridge of the house to the far end, and 

 there use branches of 2-inch pipe to carry 

 to the manifold supplying the six 1^4- 

 inch pipes under each bench. Connect 

 the expansion tank with the main return 

 close to the boiler, and be sure it is 

 several feet higher than the highest point 

 in the flow pipe in the house. The high- 

 est point in the flow pipe should be at 

 the far end of the house. At this point 

 an air valve should be placed and tried 

 at least twice .each day, morning and 

 evening, during the time the plant is in 

 operation. L. C. C. 



A VARIETY OF ESTIMATES. 



A florist here, in Missouri, is about to 

 build a greenhouse, 30x96, with 5-foot 

 concrete walls. He was thinking of mak- 

 ing it into two 15-foot spans. He has 

 estimates from a local plumber and the 

 junk man, as follows: A tubular boiler, 

 forty-eight inches by sixteen feet; eight 

 runs of 4-inch pipe, consisting of four 

 flows and four returns. He says he in- 

 tends to carry forty pounds of steam 

 pressure and use oil at 80 cents per 

 barrel. 



I have argued for a single house and 

 have figured as follows for 70 degrees 

 above outside air: For hot water, 180 

 degrees at the boiler — three 2-inch flows 

 and eighteen 1%-inch returns. For five 

 pounds of steam — two 2^4 -inch flows and 

 fourteen 1^4 -inch returns. For ten

pounds of steam — two 2-inch flows and 

 ten li^-inch returns. The house is partly 

 protected, but not much. 



Is it better to place the pipes overhead 

 or near the ground? With the heat gen- 

 erators, as the Honeywell or the Kroes- 

 chell," does the elevation of the expansion 

 tank still retain its relation to pressure, 

 as with the open system? H. G". M. 



My personal preference, in such a 



case as this, is for the one large, even- 

 span house. There is a decided saving in 

 cost of construction. There is a consid- 

 erably larger volume of confined air, 

 which is a decided advantage in sections 

 where outside temperatures sometimes 

 change quickly. 



This plant can be satisfactorily heated 

 with either steam or hot water. If I 

 were to use hot water, I would use a 

 single 3-inch flow pipe and sixteen 2-inch
