Greenhouse Heating. 



^^-^ ■"■■-■■' — ■» 



SUBSCBIBEBS are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Beview to make a choice of ap- 

 paratus 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. 



CAPACITY OF STEAM BOILEB. 



Will you please inform me how many 

 square feet of glass a 3-horsepower 

 boiler will heat by steam f 



W. G. B. S.— Ohio. 



It is customary to figure that 100 

 square feet of steam radiation can be 

 handled for each horsepower in a boiler. 

 This would be suf&cient for 600 square 

 feet of glass, if a temperature of 60 

 degrees is desired in sections where the 

 mercury does not drop much below 

 zero. However, it is advisable to shade 

 this estimate somewhat, except in the 

 case of large boilers, and with one as 

 small as 3-horsepower I would not ex- 

 pect to heat more than 800 or 900 

 square feet of glass. Even with this 

 amount, frequent firing will be neces- 

 sary. 



With a 20-inch grate about 900 square 

 feet of glass can be heated to 60 de- 

 grees with 150 square feet of radiation, 

 or 1,200 square feet can be heated to 

 50 degrees. The same grate and boiler 

 will heat the foregoing amount of glass 

 more economically when piped for hot 

 water, but nearly twice as much radia- 

 tion should be provided. The attention 

 required will also be greatly reduced. 



WISHES TO USE S-INOH FIFE. 



I have a range of six houses, which 

 I wish to heat with hot water. Five of 

 the houses run east and west and all 

 of these are 10x110, except the violet 

 house at the south side, which is 7x110. 

 The north wall of the range is six feet 

 high; the lower two and one-half feet 

 are concrete and the rest of the wall 

 is glass. The south wall of the violet 

 house is three feet high, and consists 

 of one and one-half feet of wood and 

 one and one-half feet of glass. At the 

 east end of the 10-foot houses is a 

 lean-to, 18x40 feet, with 6-foot walls. 

 I wish to know whether two 3-inch 

 runs of pipe in each house will main- 

 tain a temperature of 60 degrees in 

 }^»ero weather, and whether a 14-horse- 

 ' 'power upfiglrt 'boiler will provide heat

 wonderful greenhouse

 have nsed other makes 

 are constantly giving 

 the Kroeschell the 

 highest praise.
