You can positively rely on Kroeschell Boilers to 

 produce an even and steady supply of heat, in- 

 suring the most perfect growing conditions at all 

 times. 



KROESCHELL BOILERS 



Have a larger proportion of direct fire surface 



than any other boiler, and are known as the 



quickest hot water heaters and the fastest steamers ever designed 



—easily installed— burn any kind of fuel.

Greenhouse Heating. 



SuBSOBiBEBS Ere invited to write the 

 Editor of this Department vrith regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Beview to make a choice of ap- 

 paratuB for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



DEFECTIVE CIRCULATION. 



Some time ago I wrote to you about 

 my new greenhouse, which is 23x100 

 and has two feet of glass in the sides. 

 I told you I did not want pipes under 

 the benches. I have put seven 2-inch 

 pipes as returns on eacli side and one 

 2-inch flow pipe on each plate. Now, 

 I may not have followed your direc- 

 tions closely enough, for I do not have 

 satisfactory results. The main flow 

 pipe rises six feet above the top of the 

 boiler, forming the highest point in the 

 system, and enters the house at each 

 side of the door. Then each flow drops, 

 say, two feet, slopes to the plate and 

 runs along till it enters the header, 

 and that is where I think the trouble 

 is. The opening for the flow pipe is 

 in the middle of the header and I told 

 the steam fitter it should enter at the 

 top of the header. When we started a 

 fire, the top pipes of the returns — that 

 is, the three above the opening in the 

 middle of the header — were cold and 

 the bottom ones were extremely hot. 



L. M.— Can. 



The trouble described might be due 

 to several causes, but without knowing 

 more about the conditions we are not 

 able to determine the exact source of 

 the difficulty. We advised using either 

 two 3-inch or three 2i^-inch flow pipes, 

 but, as we understand from the letter, 

 two 2-inch flows have been used. We 

 would not expect an even circulation 

 in seven 2-inch returns supplied by a 

 single 2-inch flow pipe, and while 21/4- 

 inch flows might be used we would pre- 

 fer 3-inch flows in the severe climate )

of Nova Scotia, especially if a temper- 

 ature of 60 degrees is desired. 



When the returns are below the grate 

 of the boiler, it often happens that the 

 water iu the lower coils will not circu- 

 late, and i5 that is the case in this 

 greenhouse the difficulty can bo reme- 

 died by raising the return pipes. A 

 slope of one inch in fifteen or twenty 

 feet is all that is necessary if the pipes 

 are properly lined up. 



As stated iu our previous reply, we 

 would prefer to use as flows either two 

 3-inch or three 2i/^-inch pipes, although 

 it will answer if five 2-inch pipes are 

 substituted.

IMPERFECT COMBUSTION. 



We are having trouble in getting our 

 boiler to heat and are at a loss to know 

 how to remedy the trouble. We have 

 a No. 3 Kroeschell boiler to heat 5,000 

 square feet of glass. With the water 

 in the boiler at 160 degrees and the 

 outside temperature at zero, we can 

 keep the necessary temperature, but 

 this season we are not able to get the 

 water in the boiler hotter than 140 de- 



install a WILKS

 troubles. 



No night fire- 

 man required— 

 as the magazine 

 or coal chamber 

 holds sufficient 

 fuel to keep fire 

 10 to- 12 hours 

 without atten- 

 tion. Best made 

 for a small 

 greenhouse.

 is not enough to keep the houses warm. 

 The trouble seems worse this season 

 than usual. 



We seem to have a poor draft, as the 

 soot accumulates so fast in the flues 

 that it is necessary to clean them out 

 two or three times during a bad night. 

 Several times this fall the flues and
