Be prepared for a coal shortage after 

 April 1. There may be no closing of the 

 mines because of labor troubles, but the 

 coal operators predict a shut-down. 



A STORE AND GREENHOUSE. 



Will you please inform me how many 

 2-inch pipes, for water heating, will be 

 needed in my store and greenhouse, of 

 which I enclose a diagram? I should 

 like to run the pipes on both sides. 1 

 am using one 3-inch pipe for a main. I 

 wish to maintain a temperature of 60 de- 

 grees in zero weather. The buildings run 

 east and west. I am located in eastern 

 Missouri. M. H. 



The sketch shows the store to be really 

 a conservatory, with a vertical glass wall 

 eight feet high on three sides, the other 

 wall being the brick wall of the adjacent 

 dwelling. This house is 20x25 feet. The 

 other greenhouse joins this at one corner. 

 It is 15x40 feet, with a glass wall three 

 and one-half feet high all around. The 

 boiler is located in the cellar of the dwell- 

 ing, near the northeast corner of the con- 

 servatory, while the greenhouse joins the 

 conservatory at the southeast corner. The 

 conservatory has a door at the west end, 

 and there is a door at the east end of the 

 greenhouse, in addition to the one which 

 leads into the conservatory. 



A 3-inch main will answer for both 

 rooms. From this two 2 ^/^ -inch flows 

 should be taken off in the conservatory 

 and carried on the walls around to the 

 front door, where each should be joined 

 to a return coil of eight 2-inch pipes. 

 Two 2%-inch flows should ^Iso be carried 

 into the greenhouse and run on the walls 

 around to the door, or they can be car- 

 ried on the purlins. Each of these flows 

 should be connected with a coil of six 

 2-inch returns. The returns from the 

 greenhouse and from the coil on the south 

 side of the conservatory should pass 

 along the east wall of the conservatory, 

 where they will supply the needed heat. 



WARM AIR FOR VENTILATION. 



We intend putting up another house, 

 20x75 feet, and should like to get your 

 opinion regarding my idea of ventilating. 

 Our boiler has 1,200 feet of radiating 

 surface, the top being two feet six inches 

 below the level of the floors. It has a 

 .14-inch steel stack. Do you think we 

 would save any fuel if we were to carry

out the following plan? We would in- 

 sert a 6-inch steel pipe in the center of 

 the stack, close to the boiler, run it up 

 about three feet and connect it with two 

 elbows, one leading in at the bottom with 

 a cold air shaft from outside the house, 

 while the upper one would be connected 

 with pipes such as are used for hot air 

 furnaces and these would be run under 

 the trays in addition to the hot water 

 pipes. Then, instead of having ventila- 

 tors such as are now used, we would have 

 a perfectly tight roof, with about flve 

 12-inch pipe ventilators on the ridge, 

 each having a damper, with a swivel on 

 top and a weather vane on each, so as to 

 turn the mouth from the wind. 



It appears to me that this would give 

 a circulation of pure, warm air all the 

 time, and would also use the waste heat, 

 without chilling the water in the boiler. 



A. W. F. & S. 



If an attempt is made to carry out the 

 plan proposed, it will most likely result 

 in a far greater failure than with moat 

 hot-air heating, which is really what this 

 amounts to, although of course it is also 

 designed for ventilating purposes. It 

 will be difficult to secure any circulation 

 at all, especially against the wind, and 

 taking it all in all it will be found a poor 

 substitute for ventilating sash. If a 

 good circulation could hs secured, the 

 ridge ventilators described might answer 

 fairly well, but even then it would gen- 

 erally • be better to take in a small 

 amount of fresh air directly from out- 

 side, rather than attempt to pass it 

 through the smoke flue. 



VAPOR ON SHED WALLS. 



Last summer I built a shed, 10x60 

 feet, at the end of my greenhouses. The 

 shed is • covered with tar paper or felt. 

 There is a glass partition between the 

 shed and the greenhouses. I am located 

 in West Virginia, and use gas for fuel, 

 heating with st.eam. The boiler is in a 

 pit at the end of the shed. The pit is 

 eight feet deep and has an asbestos board 

 floor over it. No fumes escape. There is 

 a 3-inch flow and a 2-inch return at the

high side of the shed, which is a lean-to. 

 Now, my trouble is this: Starting 

 about three feet from the flow pipe, and 

 on down the roof and sides, the boards 

 sweat to such en extent that they are all 

 warped and bulged and out of place. 

 This is worse in a time of severe cold 

 than in moderate weather. I think it is 

 caused by the gas. I thought of running 

 a steam pipe on the lower side of the 

 shed, where the wall is four feet high 

 from the foundation. I have a neighbor, 

 a florist, who uses gas for fuel and has 

 a hot water heating system. Though he 

 has a shed with a tin roof, he has none 

 of the trouble which I have been describ- 

 ing. My shed is comfortably warm and 

 there arc no leaks in the heating pipes. 



F. C. S. 



From the statement made, there is no 

 reason for looking for any other cause 

 than because the air is heavily charged 

 with moisture and, coming in contact 

 with the cold boards, is condensed. The 

 fact that gas is used for fuel has nothing
