COAL OR NATURAL GAS. 



AVc liavc ;i liousc 20x]]0, heated by 

 a boiler Avliich is eight feet in length, 

 witii a iirebox 2 x I! feet. We heat by 

 steam and have about 7<)(i feet of '2- 

 inch jiijie in use. Jt requires a ton of 

 coal a ^vee]v to heat the liouis(> in mod- 

 erate weather and u little more in zero 

 Tvcather. How many feet of gas would 

 be equivalent to the ton of coal, or 

 would heat the house for a week? 

 "Which would be the cheaijer, coal at 

 $2.5U to .+;; ])er ton or gas at ]2''i. 

 cents ]ier thousand? A neighbor has 

 a well that wo can get for $oU per year, 

 but we can not t(dl whether the flow 

 would be suflicient to run the boiler. 

 A gas company will furnish us gas at 

 12^/0 cents per thousand, J>ut we think 

 that would make too nundi difference 

 in the cost of heating. Our location is 

 northern Ohio. O. E. K. 



The temperature at which tlie house 

 is kept is not stated and it is not possi- 

 ble to judge of the eOiciency of the 

 system, but with the amount of pipe 

 mentioned, if ]iroi)erly installed, tliere 

 should be no diOiculty in maintaining 

 a temperature of GO degrees in zero 

 weather. One ton of coal per week 

 should keep up this temperature, with 

 the weather averaging 10 degrees above 

 zero at night. 



A goo<l deal depends on the quality 

 of the coal, but if it is a good grade 

 of run of mine, the gas at 25 cents per 

 thousand cubic feet should be found 

 about as economical as the coal when 

 allowance is made for the labor of 

 firing, removing ashes, etc. It would 

 not be safe to rely upon the well men- 

 tioned, as the pressure might go down 

 some cold night and serious harm might 

 result. The well niav be a bargain at 

 the price mentioned, and could l)e used 

 with safety if a connection with the 

 city gas main is also made, for use 

 in case the pressure of natural gas fails. 



COPPER FLUES IN BOILERS. 



lias any brother florist had experi- 

 ence with copper flues in boilers? The 

 manufacturers of my boiler discour- 

 age the use of copper flues on account 

 of their high cost, though admitting 

 at the same time that the life of their 

 superior charcoal-iron flues is only 

 about seven years. Wlien o7ie notes 

 the great nundier of boiler fhu's ad- 

 vertised for tliis, that and the otlier 

 purjHtse, he is douldful whether the 

 average life of iron or steid flues is 

 that loiii.'. 



1 asked a jiroininent construct ion en- 

 gineer what lie thought of copper llues. 

 He condeniTit^d the idea of using flu>m 

 in a hot water boiler, liecause of their 

 high cost. He admittdl, however, that 

 he had nevpr given the subject much 

 thought, and stated that he had noticed 

 that when sjiace was an object, when

An Innovation in Steam Trap Design 



and Construction 



THE NEW 



ire devoid of all onnecessiry 



fflechanism. 



Every part designed, mannfactnroA 



and assembled with the idea if 



permanence foremost. 



Every tilt of the trap shows that 



it's working— draining every dri^ 



of condensation from the heatiBf 



system and automatically retnniM 



it to the boiler— no pumps — m 



trouble. 



Condensation is the purest kind of boiler feed water. Don't waste it. Return it directly to tlie boiler
