I intend to use a Wilks boiler, 30x42. 

 Will that be large enough! I am located 

 in northern Kentucky and should like 55 

 degrees in zero weather. We cannot go 

 into the ground more than two feet, but 

 by using a closed tank I think I ought 

 to get good circulation. G. O. K. 



If you cannot put the top of the 

 boiler below the level of the returns on 

 the sides, then you will get best results 

 by using the single overhead flow — the 

 3-inch flow. The only way to increase 

 the pressure in your system is by ele- 

 vating the expansion tank. Connect the 

 tank with the main return close to the 

 .boiler and place the tank twelve or 

 fifteen feet above the highest pipe in 

 the house. This will give you eight or 

 ten pounds of pressure; thirty-three 

 feet will give fifteen pounds. I would 

 not advise the use of 1^4 -inch pipes for 

 hot water on 100-foot runs; 2-inch will 

 be all right. The next larger size of 

 boiler would be better. A 30x42 is rated 

 to carry 600 to 700^ feet. You have a 

 little over 600 feet, which is a full load 

 for the boiler. L. C. C. 



PIPING IN OHIO. 



Please instruct me how to pipe my 

 greenhouse, 12x50 feet, four feet to the 

 plate and seven feet to the ridge, and 

 contaioing two benches. I have an up- 

 right boiler, three feet in diameter and 

 six feet high, with one 10-inch flue 

 through the center. The grate is thirty 

 inches in diameter. The boiler has a 

 1%-inch hole in the top and a 2-inch 

 hole at the bottom. I should like to 

 use 1%-inch or 2-inch pipe. 



Please state how much the bottom of 

 the boiler should be below the level of 

 the house floor, as I wish to keep it as 

 high as possible. How high should the 

 tank be above the top of the boiler t 

 What size should the tank be! Will 

 the same boiler heat one more house of 

 the same size as the present one! 



T. F. 



Your house should have eight lines of 

 2-inch pipe in it to maintain a tempera- 

 ture for carnations. This will serve best 

 if installed so as to place four lines of 

 pipe under the bench on the most ex-
