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 experi- 

 ments and perfected the new "Richmond" which. 

 in actual practice, developes 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 



Radiators 



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" 



The fuel economy it brings, more than repaid the ex- 

 periment 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 than 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 a cross circulation water way 

 which does for the water circulation what the "diving 

 flue" does for the fire travel. 



We learned how to arrange doors and drafts and damp- 

 ers so that tending the fire becomes a simple, easy, exact 

 science, instead of a difficult, haphazard uncertainty. 



Self Cleaning Surfaces 



We learned how to make 90 per cent, of our surfaces 

 self-cleaning — so more efficient. 



And in countless ways, the boiler with windows enabled 

 us to save half your coal, double ease, flexibility, satis- 

 faction — without increasing the first cost of the heating 

 system to you. 



The RICHMOND" heating system as perfected to-day 

 represents the climax of inventive 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 indirect — in your home or building, 

 large or small, write us. Ask for catalog 271. Be fair 

 enough to yourself to learn of a system which, by inventive 

 ingenuity, saves its own cost, pays its own maintenance.
