I^VAPOR HEATING SYSTEM 
How you dread exchang¬ 
ing the warmth of your bed 
for the cold morning cheer¬ 
lessness of the average bath¬ 
room ! Install Dunham 
Heating and your winter- 
morning martyrdom is over. 
You can go to bed knowing 
that bedroom, bathroom, 
every room in the house, will 
be warm and cheerful in the 
morning. 
The Dunham Thermostat 
can be set in advance to pro¬ 
vide two temperatures—one, 
whatever you desire for com¬ 
fort during the day and even¬ 
ing; the other, whatever you 
decide the house should be 
kept at during the night. 
The Dunham Radiator 
Trap prevents knocking and 
pounding in radiators. For 
it automatically expels the 
cause of the noise—air and 
water. It does away with the 
spurting, hissing air valve. 
The Dunham Inlet Valve 
enables you to turn the heat 
either on or off, with a single 
turn, without even stooping. 
Investigate Dunham Heat¬ 
ing before contracting for the 
heating equipment in your 
new home. When moving 
into a new house see that it is 
Dunham heated. Dunhamize 
your present heating system. 
Any Dunham office will 
be pleased to give your needs 
individual study, to furnish 
precise information as to cost 
and best methods of installa¬ 
tion. Send for our booklet, 
the “3 H’s.” It throws a new 
light on the heating problem.
