ing into the boiler, it makes the journey 

 again to the farther end of the house and 

 back. This piping does not work effect- 

 ively. 



The expansion tank is fifteen feet above 

 the riser and is attached to the return 

 close to where it enters the boiler. The 

 return pipes, before dropping down into 

 the boiler, are about on a level with the 

 top of the boiler, which is a Bolton heater 

 and has plenty of capacity. It is diflBcult 

 to keep it from boiling over. E. C. H. 



It is possible that one reason for the 

 trouble from boiling over is that the 

 boiler is larger than is required. An- 

 other reason is that the amount of radia- 

 tion is considerably less than should be 

 used to heat a house of the size described, 

 and then, too, the arrangement of the 

 piping is such as to prevent the rapid 

 circulation of the water, and these all 

 tend to increase the boiling over of the 

 heater. 



One method of correcting the difficulty 

 would be to use it as a closed system, 

 and this certainly should be done if the 

 zigzag arrangement of the coils is to be 

 retained and no more radiation is to be 

 put in. 



A better way would be to put in six- 

 additional 2-inch returns and connect 

 them at each end, so that there will be 

 two coils of six pipes each, through which 

 the water can return directly to the 

 heater, without traveling back and forth 

 through the coils as with the present ar- 

 rangement. The arrangement of the flow 

 pipes, with one 2-inch main on each side, 

 need not be changed, but it will be better ■ 

 to connect the expansion tank with the
