the center. Following the method out- 

 lined, I found that the figures for ex- 

 posed glass, side wall area and cubic 

 contents were 2,252, 680 and 17,938, re- 

 spectively, and that the respective re- 

 sults when these were divided by the 

 figures given were 751, forty-six and 

 sixty, which gave a totaJ of 857 feet of 

 radiation required. A circular from a 

 manufacturer gave 825 feet for the 

 same house. 



I shall be glad to know if my esti- 

 mate is correct. E. B. F. — Pa. 



In a general way, the method sug- 

 gested for estimating the amount of ra- 

 diation is a good one, but the ratios 

 given should be used for providing 60 

 degrees in zero weather, instead of 50 

 degrees as stated. For 50 degrees un- 

 der the same conditions, the divisors 

 would be four, twenty and 400, respec- 

 tively, for glass, wall surface and cubic 

 contents. 



When it came to checking over the 

 data furnished, I was somewhat in 

 doubt. Although reference is made to 

 glass in the side walls, the exact amount 

 is not stated. Judging from the total 

 amount of exposed glass and of wall 

 surface other than glass, there would 

 be about sixteen inches of glass in the 

 side walls and one end of the house, but 

 from the cubic contents of the house it 

 would seem that the walls are about 

 seven feet in height. If the concrete 

 walls are three feet in height, there 

 must be approximately four feet of 

 glass, and I am in doubt which is cor- 

 rect. 



In actual practice, when computing 

 the radiation for a house of this size.

the cubic contents may be ignored, and 

 if there is not more than sixteen inches 

 of glass in the walls it should be pos- 

 sible to maintain a temperature of 50 

 degrees in zero weather with 600 to 615 

 square feet of radiation, while for 60 de- 

 grees from 800 to 820 feet should be 

 used, the exact amount recfuired de- 

 pending upon the thickness of the walls. 

 It is, of course, presumed that the 

 house is well built, with tight joints.
