Greenhouse Heating. 



Subscribers are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, tlie jjiping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each boiler adver- 

 tised in The Keview is a good boiler, and 

 the advertisers sell them on their merits. 



SIZE OF BOILER. 



What size of hot water boiler will be 

 needed for a house 30x100, ta heat it to 

 at least 60 degrees in zero weather? 

 Our location is western Missouri. 



J. P. W. 



In a house measuring 30x100 feet, to 

 be heated to 60 degrees in zero Weather 

 by means of liot water, about 1,200 

 square feet of radiating surface will be 

 required, and to supply this amount of 

 radiation with economy of fuel the 

 heater should have a rating for 1,500 to 

 1,600 square feet. A simple method of 

 arranging the piping would be to use 

 four 214-inch flow pipes and sixteen 2- 

 inch returns. Two of the flows could 

 be under the purlins and the others on 

 the side walls. The returns could be 

 distributed in four or more coils on the 

 walls and under the benches. 



BUILDING AND PIPING A HOUSE. 



At present I have one greenhouse^ 

 10x40, running east and west, with the 

 boiler at the west end of it, and I pro- 

 pose to build another house, 2ox60, run- 

 ning east from the present house. I 

 wish to get your advice about the con- 

 struction and piping of the new house. 



I want to use a concrete and wood 

 construction, but am not sure that my 

 idea is practical in regard to fastening 

 the eaves to the top of the wall. The 

 idea is to have iron bolts imbedded in 

 the last course of concrete, so that the 

 bolts will jjroject above the concrete 

 about three inches, and then to drill a 

 2x6 cypress sill, to rest directly on top 

 of the wall. The question is: How am 

 I to get sufficient fastening, with a slope 

 the same as the roof, for my mullions 

 at the eaves? Should the eaves slope in 

 or out of the house? How much pur- 

 lin support will be required? Is it nec- 

 essary to tie the purlins by cross-pipe 

 connections, or just run them the entire 

 length of the house? I should also like 

 to get suggestions as to the height of 

 the ridge and the side walls, the length 

 of the sashbars, the thickness of the 

 concrete wall and the depth to which it 

 should be set in the ground. 



How much piping would be required 

 to grow a stock of miscellaneous potted 

 plants, including geraniums, bulbs, 

 primulas, etc., and perhaps a bench or 

 two of carnations, in this New York 

 climate? As the boiler-room is at the 

 west end of the plant, the piping, of 

 course, must be laid through the present

Dear Sir:— 



You ask to explain about the Morebead Traps. I am so well please<l 

 with them and don't see how I could »ft along without them. I have two 

 No. 3 Traps. My houses are en the level. althouKh I have just a little fall 

 to the receiver. My returns are 2 In.; main, 4-in.. 100 ft. ; 12,il00 fwt m. 220r< 

 ft. 2-ln. My bailers, one 60 and one 80 horse-power; my houses are 7 ft. to 

 gutter and I heat 60.000 square feet. I have never had any trouble with 

 keeping my houses warm bince I had the Morehead Steam Trap. 



Btst wishts, 



Yours truly,
