HOT WATER IN LONG HOUSE. 



Will you kindly advise me as to the 

 size and horse-power of a horizontal 

 boiler, for hot Avater, that would be re- 

 quired to heat an even-span house, 30x 

 242 feet; sides of house twenty-two 

 inches high; double boards; eleven feet 

 to ridge? How many runs of 4-inch 

 cast-iron pipe will be required to heat 

 to 55 degrees in zero weather, New Jer- 

 sey climate? Would one flow and one 

 return on each side keep up a night 

 temperature of 50 to 55 degrees? What 

 would be the proper rise of the 4-inch 

 pipe in the 242 feet, from the boiler to 

 the far end? How deep should I dig 

 the boiler pit for hot water heating? I 

 mention the 4-inch cast-iron pipe, as I 

 have it on hand. The house is for grow- 

 ing lettuce. F. W. V. 



It would not be advisable to attempt 

 to heat the house with hot water after 

 the plan indicated, as the lines of pipe 

 would be too long for effective service. 

 If the boiler could be placed in a pit 

 about midway and at one side of the 

 house, a hot water system would be sat- 

 isfactory, as the pipes could then be run 

 in both directions. Three flows and six 

 returns will be required, or nine 4-inch 

 pipes throughout the length of the house, 

 exclusive of headers and connections. 



A twelve horse-power boiler will be 

 required, but a sixteen horse-power would 

 be more economical to operate. The top 

 of the boiler should be at least eighteen 

 inches below the lowest part of the heat- 

 ing system in the house. The highest 

 point should be above the boiler and the 

 pipes should have a uniform grade and 

 fall toward the lower or return part of 

 the boiler. L. C. C. 



STEAM FOR THREE HOUSES. 



We are planning three connected 

 houses, each 23x100 feet, running north 

 and south. The side walls are to be 

 six feet high, with twenty-four inches 

 of glass in the outside walls, and with a 

 shed across the north end. The boiler 

 room will be at the northwest corner, or 

 at the west end of the shed. We wish 

 to heat with steam. The boiler will be 

 on top of the ground, with a steam trap 

 to return the condensation. We «xpect 

 to use 1-inch pipe in the coils. The 

 greenhouses are to have solid beds, with 

 walks next to the side walls. How 

 many runs of pipe will be needed to 

 give the right temperature for roses 

 and carnations? The outside tempera- 

 ture seldom falls to zero, though on rare 

 occasions it drops to 10 degrees below 

 zero. What size of flows should be 

 used in each house? Should all the re- 

 turns be placed on the side walls, or 

 should some come back through the cen- 

 ter of the house? How large should the 

 main be in the potting shed where it 

 branches for the houses? How should 

 the return main be handled? Shall we 

 lay it across the ends of the houses and 

 drop each coil into it, and if so, what 

 should be the size of the main return? 



W. H. 



The flow header in the potting shed 

 should be 4-inch from the boiler to 

 where the flow to house No. 1 is taken 

 off; the remainder of the distance the 

 flow should be 3-inch. One 2-inch over-

head flow pipe in each house will be 

 sufficient, and this should divide into 

 twenty 1-inch returns for each of the 

 outside houses and eighteen for the 

 middle house. A more satisfactory ar- 

 rangement would be sixteen 1^4 -inch re- 

 turns in each of the outside houses and 

 twelve in the middle house. 



The return header connecting the re- 

 turns in the houses should be 2-inch, al- 

 though li^-inch will answer. This re- 

 turn header can be placed in a trench 

 just inside the houses, at a point about 

 two feet below the ends of the return 

 pipes, each pipe being provided with a 

 double elbow and connecting to the 

 header. Or the return header pipe may 

 be laid beneath the floor of the potting
