the use of overhead flows is not so ab- 

 solutely necessary as when the returns 

 are on a level with, or below, the top 

 of the heater. 



Warm air, of course, tends to rise. 

 Therefore, in order to keep the heat 

 where it can be utilized by the plants, 

 the returns should either be under the 

 benches or on the walls, not more than 

 two or three feet from the floor. Ordi- 

 narily we prefer to run the flow pipes 

 downhill, and in order to secure the 

 needed fall for the flow and return pipes 

 we think it well to place the flow pipes 

 for supplying the coils for the walls or 

 side benches on the wall plates, unless 

 the returns are below the top of the 

 heater, in which case the flow may be 

 carried near the ridge. 



For houses more than ten feet wide, 

 if there is a middle bench for which 

 bottom heat is desired, a flow may be 

 run overhead to supply a center coil, in 

 addition to the flow pipes on the plates. 

 In still wider houses, in which there are 

 four or five benches, other flows may be 

 carried on the purlin posts, or suspended 

 from the purlins. As a rule, we prefer

to keep the flows away from the glass, 

 but they should not be so low as to in- 

 terfere with the growth of the plants, 

 or with their care. In all except the 

 narrowest houses, the middle flow pipe 

 may be two to four feet below the 

 ridge, but if the pipes at the purlins 

 are more than one foot below the glass 

 they will generally be in the way. 



In most cases the best results will be 

 obtained by locating the flows several 

 feet above the returns, but this is not 

 necessary vsrhen the returns are well 

 above the boiler.

well as the number of them, depends 

 upon the length of the house and the 

 size and number of the returns. As a 

 rule, we prefer 2-inch flows in narrow 

 houses fifty feet or less in length, but 

 would use 21/2-inch flows for houses fifty 

 to 200 feet long and 3-inch for houses
