STEAM FOB THSEE HOUSES. 



Enclosed you will find a sketch of 

 our range, which we intend soon to 

 pipe for steam. "We built one house 

 last year — the center house, 30x100, 

 which we heated with hot water, and 

 we are now building two additional 

 houses, one of them 40x100 and the 

 other 20x70, with the boiler room and 

 Workshop at the end of the short house. 

 We have decided to change the heating 

 system from hot water to steam, as we 

 experienced considerable trouble in 

 heating the one house with hot water. 

 Please tell us what piping will be re- 

 quired for steam, to heat these houses 

 to a temperature of 60 degrees when 

 the outside temperature is 10 degrees 

 below zero. Please state, also, what 

 kind of trap you would recommend for 

 forcing the condensation back, as you 

 will note that the bottom of the bpiler 

 la t^o feet above the floor of the 

 greenhouses. We should like to use 

 nothing but 2-inch pipe for the coils 

 and a 5-inch pipe from the boiler to 

 the greenhouses. Our location is in 

 western Ohio. H. J. V. & S. 



For heating the house 40x100 with 

 steam to 60 degrees, if there is no more 

 than four feet of glass in each wall, I 

 would advise the use of a 3-inch over- 

 head flow pipe and fourteen 2-inch re- 

 turns. Two of the returns may be in 

 each walk and the others on the walls, 

 or all of them may be on the walls. 

 In the house 30x100 the flow may be 

 2%-inch and ten 2-inch returns should 

 be used. For the house 20x70 a 2-inch 

 flow and seven 2-inch returns are sug- 

 gested.
