Greeohoose Heating. 



SOFT COAL OR SEMI-ANTHRACITE? 



We have been using soft coal that 

 costs us $3.55 per ton in the bin. We 

 have not storage room for a season's 

 supply, and along towards spring the 

 price is liable to rise 50 cents or more. 

 If we can get domestic semi-anthracite 

 coal at $5 to $5.75 in the bin, we want 

 to know which will be the cheaper. The 

 soft coal is Cherokee, and the dealers 

 say it is the cheaper. It makes a great 

 deal of ashes and clinkers. J. W. M. 



It is likely that the actual number of 

 heat units contained in a ton of soft 

 coal is greater than in the semi-anthra- 

 cite. The cost of firing with the soft 

 coal will be greater and there will be 

 more ash to handle, I suspect, but you 

 are buying heat cheaper in dollars in the 

 soft coal. L- C. C. 



HOT VATER PIPING IN KANSAS. 



Will you kindly tell me how many 

 feet of 2-inch pipe, water heat, a hori- 

 zontal boiler, with twenty-three 2y4-inch 

 flues fifty inches long, will take care off 

 The grate is 23x30 inches. I use gas 

 for fuel. 



Please state, also, the number of feet 

 of 2-inch pipe, and the arrangement of 

 flows and returns, which will be required 

 for an even-span house, 24x84 feet, with 

 walls five feet high; twelve feet to 

 ridge; glass gables; three feet of glass 

 in the south wall. Half of the north 

 wall is boarded, and the other half of" 

 it joins another house. The house is 

 for lettuce, in solid beds. I have a four- 

 way manifold against the side wall, with 

 the flow entering at the top and the re- 

 turn leaving at the bottom, at the other 

 end. The water does not warm up in the 

 two bottom pipes. Is my connection at 

 fault? L. C. B. 



The boiler in question should be able 

 to care for about 1,000 lineal feet of 

 2-inch pipe. 



The house 24x84 can be heated with 

 hot water by using two 2-inch flow pipes 

 from the boiler to the far end of the 

 house, each returning through seven 

 2-inch returns. These can be arranged 

 in manifolds on the side walls, or a part 

 of them can be thus arranged, and the 

 remainder, say three from each flow, or 

 six in all, can be arranged about twenty 

 or twenty-four inches above the surface

of the bench and distributed about equal 

 distances apart across the bed. The 

 boiler in question is hardly large enough 

 to put the house on a safe basis in se- 

 vere weather. 



If your pipes are ppoperly graded and 

 the flow is ^rect from the boiler to the 

 manifold and not over 100 feet long, the 

 coil should heat up throughout.

PIPING IN SOUTHERN IOWA. 



I am about to install a hot water 

 heating system in my greenhouse and 

 would like to have some information 

 about it. My house is 17x56 feet and 

 runs north and south. The walls are 

 boarded and are three feet high ; ten 

 feet from floor to ridge. The door is 

 in the center of the south end. The 

 boiler is in a pit outside of the south 

 end, west of the door. My boiler is 

 a vertical, round steam boiler, 30x60 

 inches, with forty-three 2-inch flues. 

 My plumber proposes to make two 3- 

 inch outlets, one on each side near the 

 top, and one 3-inch return inlet at the 

 bottom, and he would run one 3-inch 

 pipe to each side of the greenhouse 

 and reduce them to one 2-inch flow un- 

 der each side bench up to the north 

 end, and there divide each one into five 

 2-inch returns and jiin them again 

 into one 3-inch main return into the 

 boiler. He would place the expansion 

 tank at the north end, overhead, and

connect to each side with a 1-inch pipe. 

 This plan might do at present, but 

 I am not quite satisfied, as 1 intend to 

 raise my glass eighteen inches and put 

 in some side ventilation, and I may 

 extend the house north twenty-five or 

 fifty feet in a year or so. I fear I 

 will not have enough circulation, so I 

 have planned to give each 3-inch main 

 two 2-inch flows and tap the boiler for 

 a 4-inch return, carrying a 3-inch re- 

 turn from each return header and join- 

 ing them into the 4-inch just inside
