HEATING INDUSTRY |
FORECASTS GAINS
Expects Extensive Program
of Replacement, Repair
and M0dernization.

An extensive program of heating
plant replacement, repairs and mod
ernization is expected during the
Spring and Summer months of 1885
by the radiator heating industry, ac-
cording to the Plumbing and Heating
Industries Bureau.
Sales of heating equipment are ex-
pected to exceed the volume in the
Fall of 1884, when heating led the
list of Improvements for which loans
under the F. H. A. plan were obtained
by home owners.
Subjected to the strains of two
severe Winters, thousands of heating
plants are in need of a major over
hauling, involving, in many cases, the
replacement of the boiler.
The hot water and steam boiler,
model 1885, is as far superior to the
boiler installed 10 or IS years ago as
the streamlined motor car surpaSSeS
the model T in appearance and luxury.
Special Types Available.
Special types of boilers are avail
able for gas, oil and coal. In addition,
there are magazine feed boilers for
the use of certain kinds of hard coal
and coke.
The chief difference between the
oil-burning boiler and the coal-fired
boiler is in the greater extent OF the
fiue surface and the longer fire travel.
Scientifically proportioned fire cham
bers and multiple waterways provide
for maximum heat absorption and
quick heating response.
The better types of oil-burnlng
boilers have so per cent more tubular
waterways than the usual coal-burn-
ing boilers. AS a result, the water in
the boiler is divided into many thin
columns, effecting speedy internal
circulation of the water and conse-
quent rapid heating of the radiators.
Heat Control Offered.
A high degree of operating economy
results from the fact that the addi-
tional heating surface effects the max
imum absorption of heat from the hot
gases of combustion.
The better types of gas-fired boilers
are designed to give perfect heat con-
troll, a high degree of operating ef-
ficiency and absolute freedom from
noise or odors.
As a result of a double brushing
action attained by compelling heat
, waves to travel back and forth from
front to rear, practically every avail
able heat unit is said to be utilized In
the improved models of gas boilers.
Important advances, too, have been
made in coal-hred boilers. Flues, heat
ing surfaces, CRATES and other features
are so proportioned that the maximum
heat output is obtained from the fuel
burned.
Built into every modern boiler is
back -and-forth fire travel that Is
three times as long as the boiler itself.
This fire travel Is so arranged that
the hot gases cannot short circuit to
the chimney nor concentrate in the
center f1ue, but must reach all heat
absorbing surfaces.
Crate Area Enlarged.
The larger crate area of the modern
boiler allows greater draft through
the fire, resulting in complete COM
bustion. The fire burns brightly, clear
and thoroughly.
To reduce to a minimum the trips
down to the basement, the boiler has
an exceptionally large fire box, which
permits greater charges of fuel.
Having designed all types of boilers
to produce the maximum amount of
heat from the minimum amount of
fuel, the manufacturers have taken
the additional precaution to prevent
the escape of this heat other than
through the steam or water pipes.
The modern boiler Is protected with q
heavy inch lining of improved asbes-
tos. This is covered with a thick steel
jacket with an attractive and colorful
baked enamel finish.
This combination of metal jacket
and asbestos not only gives the boiler
an indestructible insulation, but trans
forms it from a drab ton Of iron into
bright and colorful piece of equip
ment as handsome as an automobile.
