weather. My location, you will notice, 

 is southeastern Pennsylvania. The boiler 

 is in a pit and an overhead feed system 

 is used in the houses, except in the 

 largest one. The chimney was built for 

 a smaller boiler; it is twenty-eight feet 

 high and its flue is 12 x 12 inches. Is 

 it large enough for the present boiler? 



A. T. V. 



It is not possible to determine from 

 the data furnished just what is the 

 cause of the trouble. The amount of 

 radiation in the four houses is given 

 as 2,350 feet, which is more than ample, 

 since not more than 2,000 square feet 

 of radiation should be needed to heat 

 the houses to a temperature of 50 to 55 

 degrees. To heat such a plant, the 

 boiler with a rating of 3,700 square feet 

 of radiation also allows for a large 

 margin. 



Although I have no definite data re- 

 garding the grate area of the boiler 

 and hence cannot determine with any 

 accuracy the proper size of the chimney, 

 I would suggest that the trouble may 

 come from the fact that the chimney, 

 while it should answer for 1,200 square 

 feet of radiation, is much too small for 

 2,400 square feet. 



Fully as much depends on the skill 

 used in arranging the radiating surface 

 for each house as on the exact size and 

 amorfnt of the piping used and the size 

 of the flow and return pipes. I would 

 put in 2% -inch pipes as flows, and 

 would not use more than 400 square feet 

 with each flow and return pipe. I would 

 certainly add fifteen feet to the height 

 o^ the chimney and ^his should enable 

 the heater to supply a temperature of 

 50 degrees in the present houses. Al- 

 though a IQ-inch chimney would be pref- 

 erable, I believe that good results will 

 follow with a taller chimney, provided 

 the flow and main return pipes are largo 

 enough.
