of cubic feet of space in each room, it 

 omits two important points — the length 

 of each room and the amount of glass in 

 the side walls. Without these particulars 

 no very definite reply can be given, as it 

 is the amount of exposed glass surface, 

 rather than the cubic contents of the 

 houses, that is considered. 



Supposing that the rose and carnation 

 houses are thirty-three feet long and the 

 chrysanthemum house twenty-four feet 

 long, and that there are two feet of glass 

 in each side wall, there is nothing in the 

 data given which will explain the trou- 

 ble. The heater is a good one and is 

 amply large enough to heat the entire 

 house to 60 degrees. There is 1,000 

 square feet of radiating surface, which 

 should more than suffice to maintain a 

 temperature above 60 degrees, in all of 

 the rooms. 



It would seem that the only possible 

 cause is that the pipes are too near the 

 level of the boiler, or perhaps that they 

 are not properly graded. 



Instead of using 4-inch pipe, it would 

 have been better to use 2^ -inch fiows 

 and either 2-inch or 2% -inch returns. For 

 the carnation house it would have only 

 required three 2 14 -inch flows and eight 

 2-inch returns, and the same would have 

 answered for the chrysanthemum house, 

 while three flows and twelve returns 

 would have answered for the rose house. 



IN NORTHERN ILLINOIS. 



My greenhouse is 20x85 feet, eleven 

 feet to the ridge and two feet from the 

 path to the gutter. The south roof is 

 fourteen feet from the ridge to the gut- 

 ter and the north roof is twelve feet. 

 There is a 4-foot wall of concrete. The 

 west end of the house is extended 9x18 

 feet, connecting with the boiler room. 



Will a boiler which carries 975 square 

 feet of radiation heat the bouse to 50 

 degrees in zero weather, if the house is 

 properly piped! The boiler is made for 

 four 2-inch flows and returns. Will it be 

 advisable to run the flow pipe along the 

 side walls and return with 1^^-inch pipes f 

 There are two 4-foot benches in the cen- 

 ter and a 5-foot bench on each side. 

 Please advise how to pipe. G. H. R. 



As 600 square feet of radiating sur- 

 face is all that is needed to heat the 

 house described, aside from the connect- 

 ing house, the boiler with a capacity for 

 975 square feet should be amply large. 



While it will answer to use 1^^-inch 

 pipes, it will be better, in houses more 

 than fifty feet long, to use 2-inch pipe 

 for the returns. With four 2-inch flow 

 pipes it will be necessary to use eleven 

 1^-inch returns, while nine 2-inch re- 

 turns would be sufficient. The flow pipes 

 can all be carried on the side walls, or a

A Catalogue Worth Having 



Our new Boiler Catalogue is a valuable book to any florist, 

 large or small, and everybody who has a greenhouse ought to 

 have one of them by all means. This catalogue tells you all 

 you want to know about greenhouse heating and tells it in a 

 simple manner, so that everything is easily understood. 



One of our large customers wrote for six copies to give to 

 his men — he said it would make them valuable employees. 



Sent free to any florist on request.
