*'Test at 32'> Below Zero; Kroeschell Boiler Easy 

 to Fire )¥itli Soft Coal." 



1 have 7800 gQ. ft. of glass: this boiler would take oare of about two greenhouses of 

 the same size. I maintain a temperature from M° to ooo-dld not have tlie least bit nf 

 trouble wli^n therniomftcr was Si" below zero. In zero weather ttml at half^past nine In 

 the evening, went to bed. slepi all niRht, got up at nine in the morniiig and found a good 

 fire at that hour. The oollet is giving the very best satlrfaction. Yours is the first hot 

 water boil»-r I have had in use. but have flred 8t**am boilers of different malces. The 

 Kroe-cbell" in certainly th« b«st and quIclMSt haatlns l^llar that I h^j^ad any- 

 thing to do with. As to the Kroeschell GeneirftWr, I would t*ke no amount dlWoUey for 

 it; I can run the water above the boiling potut aud have no trouble. 1 bivr your boiler, 

 generator .and piping system ihe highest praise. . K. IT HAMILTON.

Montton The Review when yon write..' ^.fi '^ 



House No. 2 is 21x33. The sides are 

 boarded to the gutters. The east gable 

 is boarded to the gutter, and above 

 that is glaps. The west end abuts on 

 the boiler house, which is 12x21 and has 

 a boiler pit underneath. This house 

 has six li^-inch pipes under the side 

 benches. The lower end of the return 

 coils is about two feet above the top 

 of the boiler. House No. 2 has two 

 2-inch feed pipes, which go to the east 

 •end of the house and drop down under 

 the benches, there feeding the coils of 

 six pipes. The expansion tank is in the 

 loft of the boiler house, about six or 

 «ight feet above the highest flow pipe. 



A plumber here tells me I could get 

 better results by having the coils fed 

 from the boiler at the west end and 

 not placing the flows overhead, as they 

 are now; that is, he would have the 

 low end of the coils at the east end 

 And there connect them, to flow back 

 to the boiler. All plans of which I 

 liave read, however, are similar to the 

 system now used in my houses. 



My heater is a Wilks, 24x42, and has 

 only a 2-inch tap for the returns. It 

 seems that in house No. 2 a 2-inch re> 

 tnm cannot take care of the water fast 

 onough; can itf Should the opening 

 be larger, or should there be another 

 2-inch return in the emptying hole in 

 front of the boiler f At present there 

 is only one 2-inch return to receive the 

 water from the twelve 1 V^-inch pipes. 



J. J. U. 



The only criticism that can be 

 offered regarding the piping in house 

 No. 1 is that, considering the slight 

 difference between the height of the 

 .boiler and the returns, it might have 

 been better to use IVG-inch or 2-inch 

 pipe for the returns. If a good circula- 

 tion can be secured, eight lJ4-inch 

 pipes should answer when the outside 

 temperature is 25 degrees below zero 

 and six returns should be suflScient in 

 zero weather. House No. 2 has just 

 .about the amount of piping needed for 

 25 degrees below zero. 



If a good circulation cannot be ob- 

 tained, owing to the friction in the 

 small pipes, put on a generator, thus 

 forming a closed system, and by means 

 of valves shut off four pipes in house 

 No. 1 and two in house No. 2, except in 

 extremely cold weather. If the flow 

 pipes run downhill, the system is prop- 

 erly installed. For house No. 2 t^p for 

 a 2%-inch return.
