two openings, one for water to enter and 

 one for water to discharge in case of 

 overflow. Can I not connect this dis- 

 charge pipe with a return pipe? What 

 piping shall I use under the side benches 

 and under the center bench? 



I wish to maintain a temperature of 

 60 degrees, with an outside temperature 

 that sometimes goes down to 20 degrees 

 below zero. The house will be used most- 

 ly to grow bedding stock. C. G. A. 



If you contemplate heating the house 

 in question with hot water it will be well 

 to install a boiler with a rated capacity 

 of from 750 to 1,000 feet. The house, 

 to carry a temperature of 60 degrees, 

 siiould have 400 square feet of radiation. 

 This can be installed by using thirteen 

 lines of 2-inch pipe, which can be fetl 

 either from a single 2 Ms -inch flow under 

 the ridge or two 2-inch lines on the pur- 

 lins. The expansion tank should be 

 placed above the boiler, elevated as much 

 as is practicable — from twelve to fifty 

 feet — and connected to the main return 

 near th« entrance to the boiler. The ex- 

 pansion tank should be provided with an 

 overflow pipe, but this cannot be con- 

 nected with the heating system. If the 

 tank \s large and elevated there will be 

 little need for the overflow with ckreful 

 firing. The flaw pipe or pipes should be 

 carried to the far end of the house, and 

 there branched to drop to and connect 

 with the returns under the benches.

UNSATISFACTORY PIPING. 



* I have three parallel greenhouses, lo- 

 cated in central Kansas. My heating 

 plant was installed about a year ago, by 

 the city plumber, who declared it to be 

 the latest and best hot water system and 

 guaranteed it to maintain a temperature 

 of 60 degrees with the outside tempera- 

 ture at zero. However, a season's trial 

 has proved the system to be unsatisfac- 

 tory. Had it not been for the mild win- 

 ter, we should have been frozen out. 



The houses extend north and south. 

 There is a stone wall, three feet high, 

 on the west side of the range. The wall 

 on the east side consists of a foot and 

 a half of stone and a foot and a half of 

 glass. The three houses are separated 



» by stone walls, three feet high. The 

 floor level of the houses is two feet and 

 a half below the level of the ground. 

 The boiler, which is six feet below the 

 ground level, is at the north end of the 

 middle house. The west house is 12x100 

 feet, and seven feet to the ridge. It is 



^ piped with four 2-inch flows and one

2i/{,-inch return. The middle house, 

 which is intended for carnations, is 20x90 

 feet, and ten feet to the ridge. In this 

 ^ house a 4-inch main flow, running to the 

 west, is reduced to a short piece of 

 .3-inch pipe before reaching the header, 

 which separates into three 2M!-inch flows 

 and one 3-inch' flow, extending to the 

 manifold at the south end of the house. 

 From the manifold, three 3-inch pipes 

 and one 2i^-inch pipe run northward to 

 the return at the north end of the house. 

 The east house is 12x75 feet, and seven 

 feet six inches to the ridge. It is piped 

 on each side with three 2-inch flows and 

 one 214-inch return. These pipes are 

 placed, one above the other, on the sides 

 of the house. The lowest of the three 

 flows never gets as hot as the others, and 

 the returns are almost under ground, 

 throwing out very little heat. R. M. 



The west house, 12x100 feet, has about 

 one-half as much 2-inch pipe as would 

 be necessary to maintain a temperature 

 of 60 degrees. It would make the plant 

 more efficient if the flow pipe were car- 

 ried to the far end of the house before 

 entering the manifold. The system is a 

 long one for hot water without a circu- 

 lating pump, and with the present ar- 

 rangement I should expect to get several 

 degrees of difference in temperature in 

 the two ends of the house. 



The carnation house has sufficient pipe 

 for a temperature of 60 degrees, but, 

 making an indirect circulation, it is not 

 more than one-half as efficient as it 

 would be with an independent flow for 

 each coil. The flow is carried to the far 

 end of the house before entering the

manifolds. The present arrangement 

 puts all the cool water at one end of the 

 house and makes one coil much cooler 

 than the other, which is not necessary. 

 The east house, 12x75 feet, has suffi- 

 cient pipe to maintain a temperature of 

 60 degrees, but the same criticism holds 

 here as in the carnation house. If you 

 are not getting enough heat from the 

 radiation, it is possible that even the 

 modifications I have suggested may not 

 remedy the trouble. Possibly the boiler 

 is too small or the expansion tank may 

 not be sufficiently elevated and not con- 

 nected in the most efficient manner. The 

 boiler should have a rated capacity of at 

 least 2,000 feet of radiation; the plant 

 actually requires a little over 1,600, on 

 a 60-degree basis. It is likely the plant
