SIZE OF FLOW PIPE. 



How large a flow pipe would be re- 

 quired to heat 60,000 feet of glass to 56 

 degrees, in zero weather, with ten pounds 

 pressure on the boilers? The extreme 

 length of the main flow would be 250 

 feet. I intend to use a steam trap, thus 

 doing awaj"^ with any back pressure on 

 returns. A. R. 



A 6-inch main flow pipe should be suf- 

 ficient to provide heat for the 8,600 

 square feet of radiating surface which 

 will be required for 60,000 feet of glass. 



It will be much more satisfactory to 

 you to state the dimensions of the houses 

 rather than to state the glass area. 

 Glass area is only one factor in a heat- 

 ing problem; therefore, the above an- 

 swer is not as reliable as it could be made 

 if dimensions of the houses had been 

 stated. L. C. C. 



PIPE REQUIRED. 



How many feet of liA-inch, 2-inch or 

 3-inch pipe would I need in a house 22x 

 66? The south wall has three feet of 

 glass and the north wall five feet. I 

 wish to maintain a temperature of 58 

 degrees when it is 40 degrees below zero 

 outdoors. I have a Wilks self-feeding 

 heater 30x48 inches. Can I put a new 

 base under this boiler with a Martin 

 rocking grate and have boiler capacity 

 enough to heat this house and a 5-room 

 dwelling house added ? P. J. K. 



To heat the house in question with hot 

 water at 180 degrees with l^^-inch pipe 

 would require 1,260 feet of pipe, with 

 2-inch pipe w'ould require 1,008 feet and 

 with 3 -inch pipe would require 630 feet. 

 The grate question is one which can only 

 be settled by the makers of the boiler.

TROUBLE WITH HEATING. 



I have six east and west houses, each 

 20x100, and a north and south house 

 on the west end of the range. My boil- 

 ers are located at the middle of the west 

 side. I have the overhead hot water sys- 

 tem, using two Kroeschell boilers, a No. 

 9 and a No. 5. These boilers are con-

nected with an 8-inch main flow pipe 

 which runs through the west house, where 

 a tee divides it, and each east and west 

 house is fed by a 3-inch pipe. Just in- 

 side each house a tee reduces each flow 

 to 2-inch. These pipes drop under the 

 benches, where they connect with 4-inch 

 returns, so that there are three flows to 

 six returns in each house. The returns 

 are connected to a 5-inch main return by 

 2-inch pipe. 



I want to maintain a temperature of 

 60 degrees in Illinois climate, but have 

 not been able to do so. If more radia- 

 tion is necessary, could l^^-inch or 2-inch 

 pipe be used? Would it improve mat- 

 ters to have one feeder for each house? 

 How high should the expansion tank be?

pipe in them should, with water at 180 

 degrees in the boiler, carry a tempera- 

 ture between 60 degrees and 70 degrees. 

 If a single 4-inch pipe could be carried 

 from the boiler direct to the house to be 

 heated and there divide to supply the 

 three risers in the house, I think greater 

 efficiency w^ould result. The flow is cer- 

 tainly greatly impeded by reducing to 

 two inches, which should be avoided if 

 possible. The common riser is not alto- 

 gether desirable on a hot water i system. 

 With steam there is less danger of cur-
