Are noted for coal economy 

 and good results generally. 



Are constructed so as to ex- 

 pose the greatest possible 

 heating surface to the direct 

 action of the fire, thereby 

 effecting a considerable sav- 

 ing of fuel.

of five 2-inch pipes, which should be 

 carried along the walls until they reach 

 a doorway, where they should be con- 

 nected with 21^ -inch return pipes, which 

 should be carried under the doors and 

 back to the boiler. 



This provides radiation for all parts 

 of the house except in the corner 

 near the boiler. For this arrange a coil 

 of five 2-inch pipes running between 

 the doorways and feed it from the 

 2-inch flow which was extended to the 

 west end of the house, and connect with 

 the boiler by means of a 2-inch return. 

 This plan supposes that there is no 

 glass in the side walls and that the 

 top of the boiler is below the floor. 



IN PENNSYLVANIA. 



I am building a greenhouse 16x100 

 feet, side walls five feet high, with 

 eighteen inches of glass. The house 

 will be thirteen feet from the floor to 

 the ridge. What would be the best way 

 to heat this house by steam? The tem- 

 perature required will be 60 degrees 

 when the thermometer shows zero 

 weather outdoors. I do not care about 

 using extra large pipe if it can be 

 avoided. Does elevation make any dif- 

 ference with steam? S. S. S. 



To heat the house described to 60 de- 

 grees, using steam, will require about 

 350 square feet of radiating surface, 

 and to keep up steam using the least 

 possible care and with greatest econ- 

 omy of fuel will require a ten horse- 

 power boiler. 



For the feed pipe a 2-inch pipe can 

 be run to the farther end of the house 

 at a slight fall, a foot or so under the
