Greenhouse Heating. 



REMODELING A HEATING SYSTEM. 



Please have your heating expert ad- 

 vise us on the following point: We 

 expect to remodel our heating plant in 

 the coming summer and should like to 

 get advice as to which is the best 

 steam heating system — gravity, trap or 

 vacuum. "We have about 30,000 square 

 feet of glass and we expect to put in 

 another boiler, which, with the one we 

 have in now, will give us enough boiler 

 capacity for at least twice as much 

 glass as we now have. We can use 

 electric power to operate the pump. 



T. W. C. 



While a gravity system is the cheap- 

 est and simplest, provided the boiler 

 can be readily located so that it will be 

 three or four feet below the lowest 

 part of the coils, and while the modern 

 traps will give good satisfaction if a 

 steam pressure of at least five pounds 

 can be obtained, still it is probable that, 

 for a plant like the one described, the 

 use of an electric or steam pump for 

 filling the boiler will be equally as sat- 

 isfactory. 



IN SOUTHEASTEBN MICHIGAN. 



I have just built a greenhouse, 20x60 

 feet, four and one-half feet high to the 

 plate and twelve and one-half feet to 

 the ridge. I want to heat it tD 55 de- 

 grees at night, in . zero weather. The 

 sides are of double thickness, with 

 building paper between. The material 

 is grooved and tongued flooring. The 

 west end is protected by the boiler 

 house and the east end by a barn. I 

 want to use the side benches for propa- 

 gating and the center of the house for 

 larger plants. I should like to run the 

 flows on the plates, with the coils flat 

 under the benches. The center bed will 

 be solid; would it be well to run pipes 

 on each side of this bed also? Please 

 tell me what piping will be required for 

 hot water and for steam, and state 

 which would be the better. 



Enclosed you will find a sketch of the 

 boiler. Will it do the work? If I 

 build another house, 9x60 feet and ten 

 feet high, alongside the present house, 

 will this boiler take care of both housest 

 The boiler will be in a pit, deep enough 

 so that the top of the boiler will be 

 level with the ground. Can you give 

 me the address of the Northwestern 

 Manufacturing Co., Chicago, the firm 

 that made the boiler? J. M.

 and nine 2-inch returns. Eun one flow 

 on each plate and the other under the

the other returns along the sides of the

 if the middle flow and return pipes were 

 left out and two 2-inch returns were 

 added to each of the side coils.
