flow and seven l^^-inch returns. A 

 boiler rated about 450 square feet of 

 steam radiation should be used. The 

 two houses and lean-to will require 

 about 225 square feet of steam radia- 

 tion, which can be handled with a boiler 

 with a grate approximately twenty-five 

 inches in diameter. In locating the 

 pipes within the houses, carry the flows 

 at the side wall plates and the returns 

 on the side walls. 



ARRANGING COILS. 



We are building an even-span green- 

 house 18x(50 feet, the ridge of which will 

 be ten feet from the ground. The walls 

 of the house will be five feet high, two 

 feet of which will be glass. We intend 

 to use steam for heating and have a 

 boiler sixty-seven inches high which has 

 a 24-inch grate and fifty-live l^i-iuch 

 flues. What are the heating require- 

 ments for this house if the temperature 

 to be maintained is 60 degrees in a lo- 

 cality' where the temperature goes as 

 low as 10 degrees below zero? Would 

 this boiler be of sufficient size to heat 

 an additional house of similar size? We 

 have approximately 400 feet of 1-inch 

 pipe on hand, which we should like to 

 utilize in our present work if possible. 



W. & S.— Pa. 



Tor heating a house 18x60 feet, with 

 two feet of glass in the side walls, to 

 60 degrees, it would be advisable to run 

 a 2-inch flow pipe about two feet below 

 the ridge and connect it at the farther 

 end of the house with two coils, each 

 containing five 1-inch returns, located 

 on the side walls. If heat is desired 

 under a middle bench, two of the re- 

 turns may be used for this purpose, with 

 four on each wall or under the side 

 benches. 



It is impossible to determine the exact 

 capacity of the boiler from the data 

 given. Although the height of the 

 boiler is given, an accurate judgment 

 of the length of the tubes cannot be 

 made. Judging from the size of the 

 grate, it will probably answer for heat- 

 ing about 400 feet of steam radiation 

 or somewhat more than this if given 

 frequent attention. 



While it might answer to heat a 

 similar house to 50 degrees, it would 

 require careful firing and would not be 

 economical of fuel.
