fireenhoase Heating. 



Eeferring to the overflowing of ex- 

 pansion tanks, W. E. Ernsberger, of 

 Norwalk, O., expresses the opinion that 

 it is not necessary, in any case, that the 

 tank should be more than two feet above 

 the highest point of the radiation. The 

 trouble mentioned, he says, can be ob- 

 viated by running a small pipe from the 

 top of the heater, or from the highest 

 point of the flow pipe, up over the top 

 of the expansion tank, for a relief. His 

 heating plant is so adjusted and works 

 well. 



PIPING IN CONNECTICUT. 



I am having trouble with the heating 

 of my house, which is 21x104 feet, with 

 6-foot posts on the north side and 4-foot 

 posts on the south side. It is a three- 

 quarter span house, facing the south. 

 The sashbars on the north side are about 

 nine feet long and on the south side 

 about sixteen feet long. The north side 

 is all boarded up; on the west end is the 

 boiler-house; the east end is all glass 

 except two feet of boards near the 

 ground ; on the south side there are 

 twenty inches of glass. The ridge pole is 

 twelve feet high. The building stands 

 in an open, bleak place, exposed on all 

 sides. 



I am using a lO-inch tile chimney. 

 Would a brick chimney be better, and of 

 what size? The tile chimney is sixteen 

 feet high, extending four feet above the 

 ridge pole. I have a hot water heating 

 system. I have two 2i/i>-inch flows and 

 eight 2-inch returns. The maximum heat- 

 ing capacity of the boiler is rated at 

 1,000 feet of 4-inch pipe, but I can 

 hardly get my l\pu8e above freezing in 

 zero weather, and during our last cold 

 snap, with heavy winds, I froze every- 

 thing up. I am not able to get the 

 flow of water back to the boiler hot. 

 The place where my boiler stands is on 

 low ground and I cannot dig a pit, but 

 I have a fall of three feet and a half 

 from the upper end of the greenhouse to 

 the return on the boiler. Now, what size 

 of boiler in rating will it take to heat 

 this house to 60 degrees at zero outside, 

 and how much more pipe? L. C. A. 



In regard to heating your house, I 

 would suggest that you run the two 2%- 

 inch risers as overhead risers and that 

 each one be used to supply seven 2-incli 

 returns, thus making fourteen 2-inch re- 

 turns in the house in addition to the two 

 2%-inch risers. Your boiler should have
