Creenhonse Heating. 



Q][TBSCRiBERS are invited to write the 

 Editor of this Department with regard to 

 an^ 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 tlie best in the special 

 field of its adaptation. 



A HOUSE ON A HILLSIDE. 



. I have a greenhouse 21x121, built on 

 a south hillside. The house runs east 

 and west and has an uneven-span roof, 

 with the long sashbars on the south 

 side. The south bars are eighteen feet 

 long and the north bars six feet. I 

 wish to heat the house to 50 degrees 

 with hot water. Please state the right 

 sizes of pipes and the best arrangement 

 of them. I am enclosing a post-card 

 photograph of the interior of the house. 

 The side walls are five feet high and 

 the height to the ridge is nine feet. 

 The boiler will be on the low ground 

 at the southwest corner of the house 

 and can be set at any reasonable dis- 

 tance below the returns. The outside 

 temperature in this locality rarely drops 

 below zero. The north wall is banked 

 and the south one is boarded, with 

 paper between. The house is in a shel- 

 tered position. C. O. G. — Mo. 



Nothing is said about glass in the 

 side walls of the house and, from the 

 photograph, they seem to be entirely of 

 wood. We would use as mains three 

 2%-inch flow pipes, and with them feed 

 six 2-inch returns. One flow could be 

 placed upon each row of the purlin 

 posts, and the other upon the south 

 plate. Two of the returns may be 

 either on the south wall or under the 

 south bench. Another coil of two re- 

 turns may be upon the row of purlin 

 posts passing through the middle of 

 the house, either near the ground or 

 higher, as will be most convenient. The 

 tem^ining two returns may be either in 

 the north walk or on the north wall.

It will be well to have the top of the 

 boiler at least two feet below the low- 

 est return. 



XASaEB BETUBNS ADVISABLE. 



Kindly give me some advice on the 

 heating of a house 16x70, with hot 

 water. There are five feet of glass on 

 the south side and seven feet of glass 

 on the north side. The house is eight 

 and one-half feet high to the ridge and 

 is three-quarter-span. I have a lot of 

 1^-inch pipe, enough to pipe the house. 

 I also have 250 feet of 2-inch pipe; 

 will it be advisable to use this! One 

 gable is protected by a barn. I wish 

 to maintain a night temperature of 60 

 degrees. How large a boiler will give 

 the best results, if it stands three feet 

 below the lowest return and is attached 

 to the west end of the house? Would 

 you advise the use of a generator?

house has five feet of glass on the 

 south side and seven feet on the north 

 side. The statement does not make it 

 clear whether these areas of glass are 

 on the south and north sides of the 

 ridge, or in the north and south side 

 walls of the house. Since the width 

 of the house is given as sixteen feet, 

 the sides of the roof would probably 

 measure something like seven and 

 eleven feet, respectively, instead of the 

 figures given. Therefore, though seven 

 feet of glass would be an excessive 

 amount of glass for the north wall of 

 a house only sixteen feet in width, the 

 inquiry will be answered with that un- 

 derstanding, since it appears to be the 

 more probable of the two suppositions. 

 Our suggestion for heating the house 

 is to use three 2i^-inch flow pipes and 

 twelve 2-inch returns, running two of 

 the flows on the plates and the other
