desired. For 50 degrees the number of 

 returns should be reduced about one- 

 fourth. As the location of the doors is 

 not indicated, it is also impossible to 

 advise definitely regarding the arrange- 

 ment and location of the coils. As I un- 

 derstand your description, the main build- 

 ing is 25x120 feet, with a wing 13x25 

 feet along one side, at the end of which 

 house there is a boiler-pit six feet deep. 

 A 4-inch flow pipe should be carried 

 from the boiler to the middle of the main 

 building, from which point a 3-inch over- 

 head main should lead to each end of the 

 main house. From those points, wall 

 coils should be arranged. Those on the 

 northwest side should follow the wall 

 around to the boiler-room, where they can 

 be joined and connected with the heater 

 by means of a 3-inch return pipe. The 

 coils along the southeast wall should ex- 

 tend from either end to the center, and 

 from that point be connected with the 

 l)oiler by a 3-inch return. There should 

 be eight 2-inch return pipes in the coils 

 upon the southeast wall and seven returns 

 in each of the coils along the northwest 

 walls. 



LARGER PIPES NEEDED. 



I am enclosing herewith a diagram of 

 ray greenhouse, and wish to know if I 

 will have enough heating surface to main- 

 tain a temperature of 50 degrees in zero 

 weather. If not, how much more would 

 be required? 



The pipes are all seventy feet long. 

 The top of the boiler is four inches be- 

 'ow the return. There is a 50^allon ex- 

 pansion tank, which is thirteen feet 

 above the boilers. The greenhouse is 

 partly protected by other buildings on 

 the north, south and west sides. I am 

 located in Illinois. C. W. H. 



From the sketch the house appears to 

 be 15x80 feet, with fifteen inches of 

 Wooden wall surface exposed. There is 

 one 2% -inch overhead flow pipe and the 

 returns are as follows: One 2^4 -inch 

 pipe, one 2-inch, one 1%-inch, two
