 to get a premium. Thus the mine-run

TO IMPROVE THE OIEOULATION. 



We have read with interest your 

 answers to other inquiries on heating, 

 and any information you can give us 

 on the following questions will be 

 greatly appreciated, as we feel that our 

 beating system can be greatly improved. 

 We have what is called the uphill sys- 

 tem for hot water, with air vents at the 

 end farther from the boiler. These 

 cocks need almost constant attention. 

 We have thought of replacing them with 

 a small pipe running out of the roof to 

 a height above that of the expansion 

 tank. Would this be practical! 



You invariably recommend the down- 

 hill system to inquirers. Does this kind 

 of system have any advantages over the 

 uphill system? The top of our boiler is 

 almost on a level with the lowest re- 

 turns. We could lower the boiler about 

 two feet. Would the advantage justify 

 the expense, or is the present plan good 

 enough! 



You recommend connecting the ex- 

 pansion tank with the highest point in 

 the system. Our local plumbers say to 

 connect with the lowest point. Which 

 is preferable? What is the rule for 

 calculating the required capacity of the 

 expansion tank? That is, how are we 

 to know whether our tank is large 

 enough? 



Are greenhouse boilers rated for hard 

 or soft coal? Is there any difference in 

 the grate surface required for a given 

 amount of heating? 



Returns of 1^4 -inch pipe, fifty feet 

 long, are giving us much better results 

 than either li/^-inch or 2-inch returns of 

 the same length. Would a return of 

 114-inch pipe 100 to 150 feet long be 

 satisfactory? This is for hot water.
