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, the piping 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. 



BEIiATIT^ SIZES OF PIPES. 



Am I getting the best efficiency from 

 my boiler, with a 3-inch main flow con- 

 nected by three IMi-inck offshoots to 

 the manifolds under the three benches'? 

 The manifolds increase to 3-inch from 

 the 1%-inch supply. Enclosed you will 

 find a diagram which may make my 

 question clearer. N. F. 



The sketch shows a 3-inch main from 

 which three l^r^-inch supply pipes are 

 taken off to feed as many manifolds. 

 It is evident that the three li/^-inch 

 pipes will not be able to handle as 

 much water as can be furnished by the 

 3-inch main. If the coils, however, are 

 not rather large, it is possible that each 

 of the 1%-inch pipes will be large 

 enough to supply its respective coil, 

 and if so, that is all that is desired. 



Kegarding the capacity of a 1 14 -inch 

 supply pipe, it may be said that a good 

 deal will depend upon its length and 

 the height above the boiler, and the 

 actual amount of radiation will be con- 

 siderably modified by the number, size 

 and length of the pipes in the coils. 

 While it might answer for 250 square 

 feet of radiation if the supply pipe is 

 short and there are only a few mod- 

 erately small pipes in long coils, well 

 above the boiler, a maxinlum amount 

 would be 100 square feet if there are 

 numerous, rather large pipes in a short 

 coil which is but little above the 

 boiler. This would make the combined 

 capacity of the three IV^-inch supply 

 pipes from 300 to 750 square feet, while 

 that of the 3-inch main is 1,000 

 feet. 



SIZE OF FLOW AND RETURN. 



I herewith enclose a rough sketch of 

 our hot water apparatus and I wish you 

 to give ypuc opinion as to whether the 

 boiler is "properly connected. The 

 boiler was installed about four years 

 ago and gives fairly good results, but 

 I am of the ot)inion it could da better. 

 The boiler is tapped' *»vith 4-inch oi)en- 

 ings for the flow and, return. Unfortu- 

 nately, when the boifbr was connected 

 I was away from home, and the steam-

 15,000 sq. ft. off Klass and carries 25,000 sq. ft. of glass until the outside teni-

 with easy tiring since we installed your boiler. From the boiler to the farthest end of our

fitter, instead of using the 4-inch open- 

 ings, used a 4-inch bushing to a 2-inch 

 flow and return. You will see by the 

 sketch that the 2-inch flow has to sup- 

 ply twelve lines of 2-inch pipe. Would 

 the circulation not be better if a 4-inch 

 nipple and a 4-inch tee were used on 

 the flow, reducing it to 2-inch for each 

 house f Would not a 4-inch return also 

 be better? The steam-fitter argues that 

 the circulation is more rapid through 

 the 2-inch opening than it would be 

 through the 4-incll. I fail to see it.
