GREENHOUSE AND DWELLING. 



Will you advise me, on the basis of 

 the sketch 1 am sending, in regard to 

 a greenhouse and dwelling now under 

 construction? I have material on hand 

 for 3-inch and S^^-inch mains and iy-2- 

 inch returns. I also have two boilers, 

 rated at 750 square feet each. Would 

 it bo advisable to dispose of these and 

 use one larger boiler? What amount 

 of radiation will be required for both 

 the dwelling and the greenhouse? Will 

 you suggest a method of installing a 

 boiler so that eitlier building can be 

 run independently? The climate here 

 gives us several days of continued 10- 

 below-zero weather and dwellings here 

 are run near 75 degrees. The green- 

 house would need 50 degrees as a mini- 

 mum. J. O. S.— X. Y.

From the sketch it is seen that the 

 greenhouse is 24x80 feet, with five feet 

 of glass and two feet of board wall on 

 each side. The piping suggested will 

 provide one 3%-inch flow pipe under 

 the ridge, supplying six l^A-inch pipes 

 l)elow. There is also on each side a 

 2V>-inch flow pipe, which supplies a 

 2-inch return. As nearly as can be de- 

 termined from the data furnished, it 

 will require about 200 square feet of 

 additional radiation to provide a mini- 

 mum of 50 degrees in zero weather. It 

 would not be advisable to change the 

 ])iping now installed, but it would be 

 well to run three 1^-inch xeturns on

each side wall, supplying them from 

 the flows on the purlin posts. If more 

 than 50 degrees should be needed at any 

 time, four additional 1%-inch returns 

 could be added to the coils under the 

 middle bench, but it would not be neces- 

 sary for a temperature of 50 degrees. 



It is not possible to determine ac-
