Many a family knows from pain¬ 
ful experience how true is the old 
song: 
"They pushed the damper in 
and they pulled the damper out 
but the smoke went up the chim¬ 
ney just the same.”

No longer true! 
T HE PROGRESS of heating 
science up to the time when 
the American Radiator Company 
was formed is pretty well sum¬ 
marized by this old song reprint¬ 
ed above. 
Homes were either too hot or 
too cold; and no matter what you 
did to the damper the smoke 
went up the chimney, carrying 
most of the heat along. 
One of the first steps taken by the 
American Radiator Company was the 
establishment of a department for 
determining definite performance 
standards for its boilers and radiators. 
That department developed into the 
Institute of Thermal Research, the 
largest laboratories in the world de¬ 
voted exclusively to problems of bet¬ 
ter warmth. 
Here materials are tested and every 
new type of boiler and radiator must 
prove in advance precisely what it 
can do. 
Architects have long been familiar 
with the service of the Institute of 
Thermal Research. It is one large 
reason why they so often write 
"American Radiators” and "Ideal 
Boilers” into their specifications. 
Dealing as they do with life’s most 
sacred investment, they like to insist 
upon materials from which scientific 
tests have eliminated every element 
of chance. 
The little book "Better Warmth and 
Better Health,” published by this 
company, contains ten definite sug¬ 
gestions for saving coal, and other 
information of value to every home 
owner.
