While the piping in the south house 

 will probably prove satisfactory in 

 mild weather, and keep up a tempera- 

 ture of 60 degrees in severe weather 

 with careful attention to firing, I would 

 advise the use of two more returns, for 

 economical heating. If the returns are 

 well above the heater, or if a closed sys- 

 tem is used, 1^-inch pipe is satis-

 length, but with open systems it is pref- 

 erable to use 2-inch pipe for the re- 

 turns, especially if the houses are more 

 than fifty feet long. For the houses 

 in question I would advise the use of 

 two 3-inch or three 2^-inch flows, and 

 fourteen or fifteen 2-inch returns for 

 60 degrees and eighteen returns for 70 

 degrees.
