We Built a Boiler 

 With Windows in It 



We learned by experiment that some boilers 

 get twice the heat out of a ton of coal that others 

 get. It is largely a matter of harnessing the 

 fire and getting the most out of it while it is 

 still hot. 



So, to be beyond theory, beyond guesswork, 

 we built a boiler with windows in it. 



Through these windows we proved our ex- 

 periments and perfected the new "Richmond" 

 which, in actual practice, develops double the 

 efficiency of ordinary boilers. And the day- 

 after-day saving in coal will prove this to you, 

 just as the windows proved it to us.

Richmond** 



Boilers 



By building a boiler with windows in it, 

 we learned certainly about drafts, water 

 circulation and fire travel which enabled us 

 to perfect a heating system which doubles 

 efficiency and halves the fuel bill. 



We found, through the windows, that 

 the flue is more important than other 

 makers dream. 



So, by patient experiment, we perfected a 

 "diving flue" which costs us three to seven 

 times as much as other makers spend for 

 smoke connections and makes it that much 

 more efficient. 



The "Richmond" "diving flue" takes the 

 gases and smoke which would ordinarily 

 pass up the chimney and sends them back, 

 mixed with fresh oxygen, to burn anew. 



For every shovel of coal you put in the 

 firebox this "diving flue" sends half a shovel 

 back from the chimney. 



The "Diving Flue" 



The "diving flue" is our own invention. 

 It is exclusive. It can be found on no boiler 

 save the "Richmond" 



Radiators 



The fuel economy it brings, more than 

 repaid the experiment of the boiler we built 

 with windows in it. 



But the "diving flue" was not the only 

 outcome of this experiment. 



We learned more about drafts th^n had 

 ever been written on paper. 



We learned how to increase our heating 

 efficiency from 90 square feet to 128 square 

 feet, without adding to the size or cost of 

 the boiler. 



We learned how to build across circula- 

 tion water way which does for the water 

 circulation what the "divingflue" does for 

 the fire travel. 



We learned how to arrange doors and 

 drafts and dampers so that tending the fire 

 becomes a simple, easy, exact science, in- 

 stead of a difficult, haphazard uncertainty. 



Self Cleaning Surfaces 



We learned how to make 90 per cent, of 

 our surfaces self-cleaning — so more effi- 

 cient. 



And in countless ways, the boiler with 



windows enabled us to save half your coal, 

 double ease, flexibility, satisfaction — with- 

 out increasing the first cost of the heating 

 system to you. 



The Richmond" heating system as per- 

 fected to-day represents the climax of in- 

 ventive skill — a system that repays the 

 pains we put into it every day you use it. 



The "Richmond" system is small enough 

 for a three-room bungalow. Big enough 

 for a building that measures its floor space 

 by the acre. 



Write Us 



If you contemplate installing a heating 

 system, steam, or hot water — direct or in- 

 direct — in your home or building, large or 

 small, write us. Ask for catalog 23-1:. Be fair 

 enough to yourself to learn of a system 

 which, by inventive ingenuity, saves its own 

 cost, pays its own maintenance-
