fireenhouse Heating. 



Subscribers 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 Eeview 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. 



NOT ENOUGH DATA IN INQUIRY 



We have nine houses, each 15x125 

 and nine feet to the ridge. The north 

 side, south side and ends contain glass, 

 all except about three feet all around 

 being wood. It is (fesired to change 

 the heating system from hot water to 

 steam, at the same time adding about 

 23,000- square feet of new glass in 

 houses of the same type. Please jtate 

 what size of boiler should be installed 

 to care for the entire range. We shall 

 use a common return tubular boiler. 



F. C— Miss. 



It is not possible to give a definite 

 reply to the question, since no intima- 

 tion of the temperature desired is 

 given. We are also in doubt regard- 

 ing the height of glass in the walls, 

 and are uncertain whether more than 

 one house has glass in the walls. It 

 would have been helpful, also, had the 

 minimum outdoor winter temperature 

 been stated. 



Where there is no glass in the side 

 walls we would use one 2-inch flow and 

 four 1^4 -inch returns for 60 degrees 

 and three returns for 50 degrees. In 

 case there is more than three feet of 

 glass in one wall we would put in an 

 additional return. While the data are 

 quite imperfect, we think that a 75- 

 horsepower boiler will heat the range 

 even after the addition has been made. 



PIPING TWO NEW HOUSES. 



I am building a greenhouse 26x100, 

 with 6-foot side walls, each containing 

 two feet of glass. The rafters are 

 fourteen feet long and the height to 

 the ridge is about sixteen feet. I ex- 

 pect to heat this house by means of two 

 .3-inch overhead flows and the neces- 

 sary 2-inch returns under the benches. 

 How many returns will be needed to 

 carry a temperature of 60 degrees! I 

 have a gravity hot water heating sys- 

 tem. Would it be satisfactory to place 

 part of the pipes on the walls and part 

 of them under the benches?
