Modern steam and hot water 
heating is an exact science as 
expressed in Capitol Boiler instal¬ 
lations. 
There are no elements of uncer¬ 
tainty or speculation because thirty 
years of research and engineering 
experience have evolved the fully 
perfected heating units. 
For large installations or small ones, 
Capitol Boilers are a safe, sane and 
utterly dependable specification. 
Heating Contractors will heartily 
endorse this statement because 
they know that Capitols have never 
failed them. They appreciate, 
furthermore, the broadest written 
guarantee in the boiler field.
