house will liave six raised benches and 

 one bed six feet wide, with 2-foot walks 

 between. Will one 2-inch flow and two 

 2-inch returns under each bench be suflS- 

 cient? 1 have at present in my house 

 16x40 feet two 2-inch flows and three 

 2-inch returns, or about 500 feet, which 

 is satisfactory. In the house 10x45 feet 

 I have about 600 feet of 1^-inch pipe. 

 What size boiler should I have to heat 

 the whole plant? Is it necessary to 

 lower the boiler, which is at the lowest 

 corner, on account of the slope of the 

 ground, and if so, how much! 



G. J. L. 



The quantity of pipe you have esti- 

 mated, viz., one 2-inch flow and two 2- 

 inch returns under each of the seven 

 benches of the proposed house 43x45 

 feet should be sufficient to maintain the 

 heat specified. As the three houses you 

 have require in the aggregate about 

 1,000 square feet of radiation, a boiler 

 rated to carry 1,500 square feet of radia- 

 tion should be sufficient for your work.

PIPING TWO HOUSES. 



I have been having some little diffi- 

 culty in heating my houses. I have two 

 houses, running north and south, pro- 

 tected on the north by a dwelling. The 

 east house is 21x58 feet, the west house 

 16x90 feet, with two feet of space be- 

 tween. The walls are four and one-half 

 feet high, with no side sash, well lined 

 on inside and outside. The boiler house 

 is situated at about the center at the side 

 of the west house. Pleaae give me a 

 general plan for piping for hot water in 

 2-inch pipes. What size boiler is re- 

 quired? The lowest temperature is 10 

 degrees below zero. If you think best I 

 can move the boiler house to the north- 

 west comer of the west house. I am 

 planning to make the east house the 

 same length, ninety feet, and widen the 

 west house to eighteen feet, so as to 

 make use of the space between. Any 

 advice will be greatly appreciated. 



C. A. S. 



Personally I should prefer having the 

 heating plant at one end rather than in 

 the middle of houses of this length. A 

 boiler rated to carry 2,000 feet of radia- 

 tion will be ample for your work. The 

 house 21x90 feet requires 600 square feet 

 of radiation, which can be provided by 

 the use of one 2^/^ -inch flow pipe and ten 

 2-inch returns. The house 18x90 feet can 

 be heated with a 2% -inch flow pipe and 

 nine 2-inch returns. Make as few bends 

 as practicable, arrange the expansion 

 tank to connect with the main return 

 near the boiler and secure, if possible, 

 at least fifte^ or eighteen -feet eleva- 

 tion for this tank. Put air valves at 

 the high points on the flow pipes and, 

 if possible, pipe each house from the 

 boiler independently. L. C. C. 



METHOD OF PIPING. 



I wish to ask you something in regard 

 to greenhouse heating. In my new house 

 18x33 feet, running north and south, I 

 am having a hot water heater installed. 

 How should the pipes be placed, along 

 the sides of house or running underneath 

 the benches? I will grow carnations and 

 miscellaneous stock. K. C. C. 



In a house intended for carnations and 

 general stock the best satisfaction will 

 undoubtedly be derived from pipes ar-

 rule this style of piping is more econom-

 for most florists' crops bottom heat is 

 preferable to overhead heat.

BOILER CAPAQTY. 



Please tell me how much pipe I will 

 need for a 50-foot house built from the 

 end of my present range to my boiler 

 shed, for a temperature of 60 degrees 

 in zero weather. Will a boiler ten feet 

 long, thirty-six inches wide, with thirty- 

 two flues and a 3-inch return heat the

I judge from the wording of your let-
