LIMIT IN LENGTH OF PIPES. 



How long a greenhouse can be heated 

 economically and efficiently with hot 

 water, the boiler to be in a pit eight 

 feet deep; that is, eight feet below the 

 surface of the ground? Can a house 

 300 feet long be heated successfully 

 with a hot w;iter i)lant ? 



E. S. K.— X. D. 



While we ]»refer to limit the length 

 of the returns in a gravity liot water 

 system to 2r)() feet, yet in tlie present 

 case, witli a distance of about nine feet 

 between the level of the returns and the 

 bottom of the cellar, we would not liesi- 

 tate to use coils 300 feet in length. 

 However, we would be exceedingly care- 

 ful not to overload the flow i)ipes, which 

 should be either 2M> or 3-inch. One 

 21^-inch or two 2-inch returns may be 

 used with each 2i^>-inch flow pipe, or 

 either three 2-inch or two 2%-inch re- 

 turns may be used with a 3-ineh flow 

 pipe. 



In an extensive range of greenhouses, 

 and where electric power is available 

 for pumping the water, we would prefer 

 to put in an electric pump rather than 

 rely upon a gravity system in long 

 houses. In tliat case a 2-inch flow jiipe 

 would supply four l^'jinch returns. 

 Five flows, each supplying four returns, 

 would answer in a house 30x300 if a 

 pumping system is installed.

A RANGE OF SIX HOUSES. 



Enclosoil is a rough sketch of my 

 ^reen houses. Houses No. 1, 2, 3 and 4 

 form tlic jiiosent range. Houses No. 5 

 and and the store are contemplated. I 

 am heating at ])rcsent with two hot 

 water boilers, located in different places. 

 I inteml to purchase new boilers and 

 set then; uji together in a cellar under 

 the new store 1 am ai'raid the distance 

 may be too great for effect i\e heating 

 with hot water: so I wish to ask your 

 heating exjiert to describe the best way 

 of heating the liouses with steam. 



The houses are of modern construc- 

 tion, with concrete walls and with two 

 feet of glass in the sides. The present 

 exposure is about 10,000 square feet of 

 glass, but I wish to provide a heating 

 capacity for about 20,000 feet. Can 

 2-inch pipes be used to advantage for 

 return steam coils? How many feet of 

 radiation should the boiler have, to give 

 the best results? Will it be advisable 

 to raise the steam main to a height of 

 six feet above the walks, then follow 

 grade up to the far end of the house and 

 drop the pipe down to coils under the 

 benches! G. M.— N. J. 



The sketch does not give the length of 

 the old range of houses, but we judge 

 it to be about ninety feet. Houses No. 

 1 and 2, which run east and west, are 

 each twenty-seven and one-half feet in 

 width and are to be used for chrysan-

 Ad.ioining house No. 2 on the north is 

 No. 5, which is sixteen feet wide and 

 is to be used for a fern and propagating 

 house. At the nortli side of No. 5 is the 

 store, in the cellar of which the boiler 

 is to be placed. 



To heat houses No. 1, 2 and 5 with 

 steam, we would carry a 3%-inch main 

 flow pipe into house No. 5 and take off' 

 a 2-inch overhead flow. Carry this un- 

 der the ridge to the west end of the 

 house and supply six l^^-inch returns, 

 arranged in three coils under the

 This house and also No. 1 will require 

 a 21'o-int'h overhea<l flow pipe, with ten 

 I'/i-Jnch or eight 2-inch returns. In- 

 stead of using a single flow jdjie, a 

 2-inch flow might be carric^d upon each
