Greenhouse Heating. 



A 300-FOOT HOUSE. 



Please tell me whether the following 

 system of gravity, return steam heating 

 would be satisfactory in a house 300 

 feet long: The bottom of the runs will 

 be six feet above the water line of the 

 boiler and the runs will rise an addi- 

 tional seven feet in the 300 feet. The 

 main steam leader, of ample size, will 

 extend across the end of the house and 

 return back to the boiler, entering 

 above the water line. The runs, single 

 lines of 1^4 -inch or ly^-mch pipe, will be 

 tapped into the upper side of the return 

 and extend the full length of the house, 

 with an air valve at the extreme end. 

 Angle valves will be used at the bottom 

 of the runs, so as not to obstruct the 

 circulation of steam and water. 



This is an adaptation of the ordinary 

 house system of steam heating, but we 

 do not know whether single connection 

 runs will drain properly without using 

 larger pipe than 1^-inch. S. B. 



There should be no trouble about 

 using a system such as is described, 

 provided l^^-inch pipe is used, but it 

 would be better to use the lower pipe 

 in each coil as a return, running the 

 coils downhill. 



PIPING IN OHIO. 



I have two houses which I wish to 

 heat with steam. They are on a hill- 

 side and run north and south. They 

 measure four feet to the gutters and 

 nine feet to the ridge. The west slope 

 is nine feet; the east slope, fourteen feet. 

 The south gables are glass and there 

 is a potting shed at the north. There 

 is no glass in the side walls. There are 

 three raised benches in each house, ar- 

 ranged as follows: A 4-foot bench on 

 each side and an 8-foot bench in the 

 center, with a 2-foot walk between. 



What would be the best way to pipe 

 them for 60 degrees in zero weather? 

 The two houses are connected, with no 

 partition between them. I should like 

 to install a boiler that would take care
