We Built a 
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. 
Boiler WitH 
"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 thtm 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 ordinari¬ 
ly 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 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 than had 
even been written on paper. 
We learned bow 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 circula¬ 
tion 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 dampers so that tending the fire 
becomes a simple, easy, exact science, in¬ 
stead of a difficult, haphazard uncertainty. 
double ease, flexibility, satisfaction— with¬ 
out increasing the first cost of the heating 
system to you. 
The Richmond" heating system as 
perfected today represents the climax of in¬ 
ventive skill—a system that repays the 
pains vve 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 233. Be 
fair enough to yourself to learn of a system 
which, by inventive ingenuity, saves its own 
cost, pays its own maintenance. 
Self Cleaning Surfaces 
We learned how to make 90 per cent of 
our surfaces self-cleaning—so more effici¬ 
ent. 
And in countless ways, the boiler with 
windows enabled us to save half your coal,
