Green house Heating. 



LOCATION OF RETURNS. 



I wish to be informed whether under- 

 bench heating is practical, with two 

 feed lines and one return line on each 

 side and under the gutter, in a range 

 of two houses, each 18x100. Each 

 bench would have one feed line and its 

 return. I am using steam. F. L. — 0. 



The question does not give any idea 

 of the number or width of the benches, 

 but we would say that it is a good plan 

 to have at least a part of the return 

 pipes under the benches, as in that posi- 

 tion they not only help to dry off the 

 soil, if it has become too wet from drip 

 or other causes, but by furnishing bot- 

 tom heat they hasten the growth of 

 most crops. Ordinarily, when there are 

 walks along the walls, it is a good plan 

 to place a part of the returns on the 

 walls, and two or three pipes under 

 each of the benches. To heat the house 

 described, to 60 degrees in zero weather, 

 we would run a 2-inch flow along under 

 the ridge, and six l^^-i'H'h returns could 

 be placed in coils of two pipes under 

 each of the benches. F. E. 



POOR CIRCULATION. 



We have just installed a new boiler, 

 in a shed at the west end of our 

 greenhouse. It stands on a level with 

 the ground and there are two flow pipes 

 running from the boiler to the east end 

 of the greenhouse, one flow on each 

 side, on a line with the purlins. There 

 are four lines of pipe under the bench 

 on each side, running a distance of 108 

 feet from the cast end to the boiler, 

 with a fall of one foot in that distance. 

 The bottom of the expansion tank is 

 even with the top of the flow pipes and 

 connects downward with the return. 



For some reason, we get hardly any 

 circulation. We cannot put the expan- 

 sion tank any higher without putting 

 it outside, above the roof of the shed. 

 If we enlarge the expansion tank, will 

 that answer the same purpose as rais- 

 ing it? The piping throughout the sys- 

 tem is 2-inch. The smokestack is 

 eighteen feet high and twelve inches in 

 diameter. We shall appreciate any sug- 

 gestions that j'on can offer us in re- 

 gard to any defects in the arrangement 

 of the piping. We do not wish to put

the boiler in a pit if we can avoid doing 

 so. A. & G.— Kan. 



The principal reason for the trouble 

 is because the return pipes are so near 

 the level of the bottom of the heating 

 surface of the boiler. Increasing the 

 size of the expansion tank will not im- 

 prove the circulation. Unless you can 

 drop the boiler at least two feet — and 

 four feet would be better; or,' which 

 amounts to the same thing, unless you 

 can raise the return pipes, it will be 

 necessary to put on a mercury genera- 

 tor, or in some way place the system 

 under pressure. 



When used as an open system it will 

 not be possible to obtain satisfactory 

 results with 2-inch flow pipes supply- 

 ing four returns of the same size, 108 

 feet in length, and they should be re- 

 placed with 2y2-inch pipe, unless a 

 closed system is used. F, E.

 first-class shape. Large quantities of 

 chrysanthemums are in the market and 

 move nicely. Funeral work has con- 

 sumed a good share of them and few 

 have gone to waste. Some of the 

 stores dye the whites to make them 

 more salable. Among the large varie-

 of pompons are offered and these sell 

 fast. Baby is a favorite.
