Dunham Inlet Valve 
Stooping to turn the heat on or off. One sin¬ 
gle turn suffices to admit a full volume of 
heat-giving vapor. There is no wrist-tiring, 
back-racking twisting. 
And the Dunham Vapor Heating System 
permits of perfect heat control. Damper doors 
are mechanically opened and shut—thus the 
temperature of each room in the home is auto¬ 
matically kept at one of two predetermined 
temperatures. 
There is comfort in going to bed cozy warm, 
with the certainty of rising at any previously 
decided hour in equal comfort. And know¬ 
ing, positively, that all during the long hours 
of the night, unwatched, the heat of the fire 
has mechanically been tempered, and so the 
temperature has been automatically lowered. 
Dunham Heating assures positive pressure 
control, with absolutely no attention after the 
controlling device has been set. 
A world of winter comfort awaits you who 
install a Dunham Vapor Heating System—a 
comfort that is in keeping with the times— 
that is yours by right. 
Dunham Heating can be applied with equal 
success to homes in the building and to homes 
already built. A steamfitter can Dunhamize 
your old-fashioned hot-water or steam heating 
equipment. 
A Dunham Vapor Heating System is not 
cheap—neither is it costly. But it represents 
the utmost possible in material value. It will 
render a service far in excess of its actual cost.

A GENERATION ago tin bathtubs were 
a luxury. Today even the most modest 
home is equipped with shining porcelain. 
Our grandmothers boasted of their wood 
ranges, but only because they knew naught of 
the gas stove and the electric cooker. 
New standards of living and of comfort have 
supplanted the old. The present-day world 
demands much—gets much—and, when all is 
said and done, gets it economically. 
Yet you—the luxury and comfort of whose 
homes would astound a past generation— 
vou voluntarily undergo the uncertainties and 
the veritable hardships that are characteristic of 
every method of domestic heating but the Dun¬ 
ham Vapor Heating System. In this particular, 
you are content with what sufficed your father. 
You who would squirm at the thought of a 
tin bathtub, who would scorn a coal range, in 
whose homes machine-work has largely sup¬ 
planted hand-work 
—knocking, hissing, pounding radiators dis¬ 
turb your days and your nights the winter 
long, just as they did your father. 
—unreliable dampers harass you. They 
.■•equire your constant attention, cause you trip 
after trip to the cellar. So, too, your father 
was embarrassed. 
—you rise early of a winter morning in 
what is really an unheated room, or else you 
get up unrefreshed. For the night long you’ve 
breathed stale, vitiated air. In this you have 
not advanced beyond your father’s standard.

And all this hardship !—all this discomfort 
is entirely unnecessary! Has been for years 
past—since the advent of the Dunham Vapor 
Heating System. 
For the Dunham Vapor Heating System 
assures to every home in which it is installed 
an abundant comfort, an unprecedented con¬ 
venience, and fuel economy. 
Where there is Dunham Heating, radiators 
cannot knock or hiss, for the Dunham Radia¬ 
tor Trap (a device exclusive to the Dunham 
System) forces all the air and water from out 
the radiator, but it retains every atom of the

heat-giving, costly vapor. Air and water are 
responsible for noisy radiators. 
It is this appliance, too, that is in part re¬ 
sponsible for the economy of the Dunham 
System. For it conserves heat; and the price 
of heat is high. 
The Dunham Inlet Valve is a refinement 
of pronounced value. It is located at the top 
of the radiator, eliminating the necessity of
