I have a steam tubular boiler, 40-inch shell, twelve feet long, with thirty-six 3-inch flues. Can this boiler be used with satisfaction for hot water heating? If so, what is its capacity? I have two houses, 30x150 feet. H. M. B.—111. The boiler is probably rated at thirty- five horsepower and should handle about 3,500 feet of hot water radiation in an economical manner. For the best re- sults it should have four 4-inch flow pipes and four main return openings of the same size. The amount of the glass in the walls of the houses is not given, nor is any mention made of the temperature de- sired, but if there is not more than two feet of glass in each of the four side walls of the houses, and they are well built, it should be possible to keep one house at 60 degrees and the other at 50 degrees when it is 10 degrees below zero outside. The grates for the boiler should be 3x4 feet. If the houses are built together, with one wall in common, a little extra atten- tion to firing in zero weather will make it possible to keep the temperature at , 60 degrees in both houses. HEATING TWO HOUSES. I have a heating problem which is giving me a great deal of diflBlculty. The range in question consists of two houses, one 19x100 feet and the other 25x100 feet. The boiler used in the heating system is rated at 4,450 square feet of radiation. The chimney of this system has an inside diameter of eighteen inches, is thirty-five feet high and is of brick construction. In spite of the fact that I was led to believe, when purchasing this heating plant, that 1 could heat two 25-foot houses to 50 de- grees when the outside temperature is at zero, it has been impossible to raise the temperature of the water in the pipes above 140 degrees. In a trial test recently made the temperature in the 19-foot house remained at 36 de- grees and that
