THE FUEL MAXKHT. 



The arrival of winter over that part 

 of the country that has the most green- 

 J^ouse glass has brought the necessity 

 for steady hard firing, but it has not 

 brought the usual attention to the ques- 

 tion of fuel supply. The coal trade has 

 been in such a situation for months that 

 practically every grower has been loaded 

 up with all the fuel his bins will hold. 

 The market continues easy in spite of 

 the increased consumption, but prices 

 are well maintained, the mines having 

 consistently followed the policy of cur- 

 tailing production so as not to overload 

 the market. There still are bargains 

 for the man who is so located that the 

 jobbers can get to him easily when they 

 have a car or two up to demurrage, but 

 this is a condition that always main- 

 tains except in times of car shortage. 



LABOEB PIPE IS PBEFEBABLE. 



I have just completed the erection of 

 a greenhouse and am at a loss to know 

 how to pipe it. The house runs north 

 and south and is 14x30. It is eight feet 

 high to the ridge and has glass walls 

 five feet high. Please tell me how many 

 lineal feet of 1*4 -inch pipe will be re- 

 quired to heat this house to a night 

 temperature of 50 degrees in zero 

 weather, using hot water heat. What 

 size of boiler will be needed? What 

 size of main and return should be used 

 between the boiler and the greenhouse 

 and should these pipes be laid under- 

 ground? I am located in southwestern 

 Kansas. M. H. N. 



From the sketch that accompanies 

 the inquiry, it appears that the boiler 

 is located twenty or more feet away 

 from the greenhouse and eight feet 

 below the greenhouse level. The green- 

 house has a door in the south end, the 

 end connected with the boiler, and 

 there is another door in the west wall, 

 about five feet from the north end. y 



To heat the house, I would suggest 

 that you run a 3-inch flow pipe a foot 

 or so underground to the southwest 

 corner. Just inside the house, carry 

 the 3-ineh pipe up to the level of the 

 plate and extend it to the door in the 

 side wall, where a 2-inch pipe should 

 be dropped down to feed a coil of seven 

 1%-inch pipes, which should run 

 along the wall back to the southwest 

 corner. Extend the main, after reduc- 

 ing it to 2V^-inch, over the door and 

 then drop it down and feed a coil of 

 seven 1 14 -inch pipes, which should be 

 carried along the north end of the 

 house and down the east side to the 

 door in the south end. From there a 

 2%-inch pipe should run to the south- 

 west corner and there connect with 

 the other coil by means of a 2-inch 

 pipe, after which it should run to the 

 heater as a 3-inch return. This will 

 require about 500 lineal feet of l\i- 

 inch pipe. Instead of the 1^4 -inch

pipe, it would be preferable to use five 

 lines of 2-inch pipe, or 370 feet. 



If for any reason it is not possible to 

 sink the boiler so that the 3-inch flow 

 can be carried all of the way to the 

 greenhouse underground, it may be 

 above ground for a part or all of the 

 way. The heater should be rated for 

 400 square feet of radiating surface. 



LETTUCE HOUSE AND RESIDENCE. 



I have two or three questions to ask 

 you about heating. I have an upright 

 boiler, thirty inches by five feet, in a 

 pit three feet deep. My residence is 

 forty feet from the boiler room and 

 the ground is level. Hot water heat is 

 used. Can I heat the residence from 

 the greenhouse boiler? The expansion 

 tank is just over the boiler end of the 

 flows. Would it be practicable to locate 

 the expansion tank outside the boiler 

 room, in this part of Kansas, where 

 the outside temperature has been 

 I known to drop to 20 or 25 degrees be-
