house needs by placing orders with the 

 mines. The supply of lump and egg still 

 is less than the demand and the prices 

 are strong." 



PIPING FOE HOTBED BANQE. 



I intend to build a hotbed range 100 

 foet long, using 4x6 sashes. Kindly tell 

 me how many 2-inch flow pipes, for hot 

 water, will be needed to keep the range 

 at a temperature of 40 to 45 degrees in 

 zero weather. The location is eastern 

 Missouri. G. F, D. 



In case the house lias no glass in the 

 side walls and has but one row of sashes 

 on each side of the ridge, it can be 

 heated by means of one 2^-inch over- 

 head flow and four 2-inch returns. If 

 it is desired to use 2-inch pipes for the 

 flows, two should be put in, each of 

 which should be connected with two re- 

 turns. 



USING ONLY 2-INOH PIPE. 



rieaso let me know what length of 

 rafters should be used on a greenhouse 

 twenty-two feet wide, inside measure- 

 ment. Also tell me how many lines of 

 2-inch pipe will be needed to"^ heat the 

 house to 50 degrees in this Chicago cli- 

 mate. The house is 22x50, with 4-foot 

 concrete walls and two feet of glass on 

 top of the concrete. J. M. P. 



While the length of the rafters will 

 depend somewhat upon the desired 

 height of the house and the use to 

 which it is to be put, it will be about 

 right to make them thirteen feet long. 

 To heat the house described to 50 de- 

 grees will require about 400 square 

 leet of radiating surface. I would ad- 

 vise running one flow pipe a foot or two 

 below the ridge, connecting it at the 

 farther end of the house with five 

 2-inch return pipes distributed under 

 the benches. Then run a flow pipe on 

 each wall plate and connect each of 

 the flow pipes with four returns. Give 

 the flow pipes a slight fall and con- 

 nect the highest point of each with 

 The expansion tank. 



CANNOT GET SUFFICIENT HEAT. 



Please give mc some advice on how 

 to pipe my greenliouses so as to main- 

 tain a temperature of 60 degrees in the 

 daytime and 48 to 50 degrees at night. 

 All the pipes, as at present installed, 

 become uniformly hot, including the re- 

 turns up to the boiler, but more radia- 

 tion seems to be needed. I wish to use 

 2-inch pipe for flows and returns. The 

 houses are built in an ell shape, with 

 no partition. One 4-inch flow and one 

 4-inch return go through house No. 1 

 and branch to three 2-inch flows, con- 

 necting with twelve 2-inch returns in 

 house No. 2. There are also one 2-inch 

 flow and five 2-inch returns in house 

 No. 1. I am located in northwestern 

 Ohio, C. W. S. 



The accompanying sketch shows house 

 No. 1 to be 15x50 feet. This is heated 

 by one 2-inch flow pipe and five 2-inch 

 returns, in addition to the 4-inch flow 

 and return which lead to house No. 2. 

 The latter house is 30x50 and is heated 

 by four 2-inch flows and twelve 2-inch 

 returns. 



With this radiation there should be 

 no difficulty in maintaining the temper- 

 ature desired, provided the piping is 

 properly arranged. If, as stated, the 

 pipes heat up evenly, it may be that the 

 trouble is with the boiler or the firing. 



"RICHARDSON" 

 GREENHOUSE BOILERS 



Were first put on the market many years ago. They 

 were qaickly recognized as possessing special adapta- 

 bility to greenhouse requirements and have been sold 

 to florists in steadily increasing numbers as the green- 

 house industry has expanded. 



A boiler must b* a good bollor— and mado by a strong, dapond- 

 khlm manufacturor— to hava withstood the stress of competition 

 for so many years. 



The "Richardson" line has developed with the needs 

 of the trade. The "Richardson" now is made in sixty 

 sizes, round, end feed, side feed — all sectional — for hot 

 water and steam. They are low priced, but, better yet, 

 they are fuel savers.
