ONE BOILEB OB MORE? 



I should like to ask -whether one hot 

 water boiler would be sufficient to take 

 care of the following area of glass, 

 keeping everything in perfect shape 

 and maintaining just the right tempera- 

 tures in all kinds of weather, in this 

 Illinois climate. The range comprises 

 the following houses: Two carnation 

 houses, each 20x225; three rose houses, 

 each 20x200; one rose house, 40x120; 

 one rose house, 20x225; one rose house, 

 40x225. The hot water boiler is one 

 of the largest made by a well-known 

 firm. F. P. B. 



To heat the eight houses described 

 would require about 10,000 square feet 

 of hot water radiation, and it would 

 result in economy of fuel if a somewhat 

 greater boiler capacity were furnished. 

 While the size of such a boiler would 

 not be excessively large, there would 

 be some advantages in using two boil- 

 ers, each of 6,000 feet of radiation ca- 

 pacity. One of them could heat all of 

 the houses for a couple of months in 

 the spring and fall, and in case any- 

 thing went wrong with one boiler the 

 "cripple" could be cut out and the 

 heating done with the other until the 

 repairs were made. 



QBEENHOUSES AND HOTBEDS. 



I am building two connected green- 

 houses, each 21x80, running north and 

 south. I expect to use the east house 

 for roses and warm natured plants, and 

 the west house for carnations. I have 

 a boiler which is five feet in diameter 

 and sixteen feet long, and which con- 

 tains fifty-two 4-inch flues. Do you 

 consider this boiler too large to heat 

 the houses economically in this Kansas 

 climate? I expect to connect this heat- 

 ing plant with 1,000 square feet of hot- 

 beds or coldframcs. Will an S-section 

 Princeton hot water heater be suffi- 

 ciently large to heat all of the struc- 

 tures? The sections of the Princeton 

 heater, I think, are three and one-half 

 feet high by two feet wide and about 

 five inches thick. The outside tempera- 

 ture here sometimes runs down as low 

 as 22 degrees below zero, with the ac- 

 companiment, frequently, of high 

 winds. 



Where shall I tap the boiler for the 

 heating pipes? How many feet of 

 3-inch and smaller pipes shall I use for 

 heating? I expect to use hot water 

 and to fire with coal. G. F. O. 



The rose house can be readily heated 

 by means of three 2 1^ -inch flow pipes 

 and twelve 2-inch returns. In the car- 

 nation house use three flows and nine 

 returns. While one 3-inch main flow 

 and return could be used for the carna- 

 tion house, they would not be large 

 enough for the rose house, and the 

 best plan would be to run a 4-inch 

 pipe to the end of each house, where 

 the 2V^-inch flows could be joined to
