The Florists^ Review 



June 22. 1922 



horsepower boiler, since a 40-horsepower 

 boiler has already been installed, it 

 would be well to put in a second boiler 

 of the same capacity. Either of the 

 boilers will be sufficiently large to 

 maintain a temperature of 50 degrees 

 in average winter weather and the two 

 boilers will handle them easily even 

 when it is 10 or 15 degrees below zero. 



Having two boilers will be found 

 lielpful in case repairs are required for 

 one of the boilers, since, by careful at- 

 tention to the firing, one of the boilers 

 should be able to give nearly, if not 

 quite, 50 degrees in zero weather. It 

 is understood that it is proposed to use 

 21/4-inch main flow pipes for the wide 

 houses and 2-inch flows for the 20-foot 

 houses. While these would answer — es- 

 pecially if up to five pounds, pressure is 

 tarried in severe weather — it would be 

 preferable to use eitlier a flow pipe one 

 size larger or install two 2-ineli pipes 

 in the liouses liaving ex2)0sed glass in 

 tlie side walls. 



While a 5-inch pipe would answer as 

 the flow pipe for the entire system, it 

 would Ije ])referable to use a 6-inch 

 main flow when the radiation is more 

 than 3,600 square feet, or two 4-incli 

 flows may be used. 



In addition to tlie flow pipes, it would 

 be advisable to use eight IVi-inch pipes 

 in the wide house.s and six returns in 

 the narrow houses, with an additional 

 return in the liouses with an exposed 

 wall. 



FOB HOUSE AITD RESIDENCE. 



A section of my greenhouse, 38x50, 

 has its heating plant located as the dia- 

 gram I liave sent you indicates. I de- 

 sire to move the boiler from its present 

 location and i>lace it under my resi- 

 dence, making one system do for both. 

 I want to know if I can get good re- 

 sults by running the flow and return 

 pipes from tlie residence boiler to the 

 greenhouse? Could 1 thus maintain the 

 present heat of 50 degrees in the cold- 

 est weather? G. W. C— Kan. 



The sketch sliows that the boiler is 

 connected near the northeast corner of 

 the greenhouse, while the residence, in 

 the cellar of wliich it is ])roposed to lo- 

 cate the boiler, is fifteen feet west from 

 the west end of the range. 



If the main flow and return pipes are 

 carefully insulated, there is no reason 

 why the pipes cannot be carried as pro- 

 posed, even though the main flow pipe 

 is carried above ground between the 

 boiler house and the west end of the 

 greenhouse. 



PIPE and FLUES
