should be used, and 2-inch would be 

 better. Even then it should not extend 

 around the house, but the water should 

 be carried to the farther end of the 

 house in a 2 1^ -inch flow pipe, which 

 should connect with the returns. There 

 should be ten 1^-inch, nine l^^-inch or 

 seven 2-inch returns. The boiler should 

 be able to take care of 350 square feet 

 of radiation. 



WHICH EXPANSION TANK? 



Which of the following two methods 

 will produce the better results in con- 

 nection with a No. 2 Kroeschell boiler: 

 To have an expansion tank with a ca- 

 pacity of sixty gallons and a height of 

 four feet, with its base six feet above 

 the top of the boiler, or to connect the. 

 boiler to a water tank which is twelve 

 feet high and ten feet in diameter, and 

 which is elevated thirty feet above the 

 ground? All the pipes are below the 

 benches and are in straight runs. The 

 temperature required is 60 degrees in 

 one house and 50 degrees in the other, 

 in this Missouri climate. The glass 

 area is about 2,500 square feet. 



W. G. 



If the piping is properly arranged, it 

 will make little difference which meth- 

 od of connecting an expansion tank is 

 used, provided the tanks are both above 

 the highest point in the system, but if 

 the coils are lower than the top of the 

 boiler, or if the system is not properly 

 balanced in any of its parts, the ele- 

 vated tank will be more satisfactory, 

 as this will make it possible to raise 

 the temperature of the water in the 

 flow pipes several degrees above the 

 boiling point, which will improve the 

 circulation. In either case, the tank 

 should be connected with the highest 

 part of the system, which should be 

 arranged on the downhill plan. 



AN ADDITION OF TWO HOUSES. 



We have just finished the following 

 addition to our range: Two attached 

 houses, 20x50 and 26x50. The houses 

 are open under the center gutter. The 

 walls, which are of concrete, contain 

 two and one-half feet of side glass. 

 The houses are well protected from 

 cold winds. The boiler room is cen- 

 trally located, in a 100-foot service 

 building. The gable ends of the two 

 new houses are attached to the last
