on the walls, or a part of them might 

 be under the benches. This would re- 

 quire about 600 feet of 2-inch pipe for 

 house No. 1 and 525 feet for house No. 

 2. To heat the three houses will re- 

 quire a boiler with a rating of about 

 2,000 square feet of radiating surface. 

 The hotbed could be kept above 40 

 degrees in zero weather by the use 

 of two 2-inch returns and could or- 

 dinarily be kept above 50 degrees after 

 March 15. A 20-gallon expansion tank 

 will be desirable. This should be con- 

 nected with the highest part of the 

 system, which should be near the 

 boiler. The smokestack should be 

 iifteen inches in diameter and about 

 thirty-five feet high. 



A COLORADO BANOE. 



Please let us know how we can pipe 

 our houses to the best advantage, for 

 hot water. The houses run north and 

 south, with the workroom at the north 

 end and a pubHc street at the east and 

 south. House No. 1, beginning at the 

 east side, is 30x165. Nos. 2, 3 and 4 

 are each 20x165. No. 5 is 20x100, be- 

 ing cut short by the boiler foem. The 

 houses are even-span, with the gutters 

 six feet above ground. No. 1 has three 

 feet of glass in its east wall. 



The houses are all built and we have 

 been heating them with three small 

 hot water boilers, located in different 

 parts of the range, but we are now 

 putting in one horizontal, tubular 

 boiler, five feet in diameter and sixteen 

 feet long — about an eighty horse-power 

 boiler. As we have the place piped 

 for water, we think the returns, which 

 are 2-inch, would be too large for 

 steam. There is a cross walk in the 

 houses, 100 feet from the workroom, at 

 the north, and sixty-five feet from the 

 south street. The boiler, as already in- 

 dicated, is at the west side and about 

 the middle of the 100-foot section. 



Can we run the main feeder from the 

 boiler into the nearest house, house 

 No. 4, then south under the. gutter to 

 the cross walk, and then along the 

 walk in the middle of the roof, attach- 

 ing a tee at each house and feeding 

 in both directions t And can we put 

 one return in the walk and let the re- 

 turns from under the benches go into 

 it and then back to the boiler! We 

 now have one 3-inch flow and nine 2- 

 inch returns in each house. How large 

 a feeder do we need from the boiler t 

 The boiler now has one 5-inch and one 



Pipe Carriers 



We have a line that cannot be excelled. The 

 steel hook is neat, light, very strong, and stamped 

 from the best sheet steel. The prices are very 

 reasonable. 



Let us figure on your needs at least. However, 

 we know that a trial order will show you that our 

 pipe carriers are the best. Get our prices.

4-inch opening. Is that enough! How 

 large a return do we need! Can we 

 reduce the feeder and return as we 

 get toward the houses numbered 1 and 

 2? Should the main feeder be run on 

 a level, or should it slope up or down 

 a little! Where should we connect the 

 expansion tank? How deep should the 

 boiler pit be! The houses slope to- 

 ward the south. N. & E.

flow and nine 2-inch returns would 

 furnish about 55 degrees when the 

 mercury stands at 10 degrees above 

 zero outside, except in house No. 1, 

 which should have twelve returns for 

 45 degrees. The main flow and return 

 pipes should be 6-inch, but can be re- 

 duced to 4-inch when they reach house 

 No. 1 and 5-inch at house No. 3. Both 

 should have a slight downward slope, 

 with the expansion tank attached to 

 the highest part of the main flow pipe.
