Heating Methods
Refined Under
Defense Spur
By HILSON MUNSEY.

FOunQ necessity. lney usually are
made of galvanized iron or copper,
but there are also other kinds that
have their own particular advan-
tages. The usual enemies of the
tank are corrosion and rust, particu-
larly in districts where water con-
tains such chemicals as lime. These
chemicals produce not only corro-
sion, but water that is Objectionable
In appearance ewes if it is not dam
gerous to health.
A variation of the iron or copper
tank is provided by one that is less
expensive than the copper tank, as
a rule. 1t is made by fusing glass
both onto the exterior and interior
of steel shell at very high tenn
perature. With the needs of the de-
fense program for metals this offers
an excellent solution to the hot
water tank problem.
The tank cannot rust out or wear
out and its cost is little more than
the cost of the average hot-water
tank.
Defense Poses Problem.
The defense program has posed
another problem that may become
acute this winter and that is the
adequate heating of the house. How
much oil or coke or coal will be
available cannot be forecast and
the home owner may find himself
with first-class heating system
without enough fuel to run it prop
erly.
If there is to be a change in your
heating unit, the use of gas as
fuel should be seriously considered.
1t has many advantages. 1t is auto
matte and requires no attention. The
repair man is available at any mo-
ment, by means of a simple tele-
phone call, and the fuel is paid for
after it is used monthly instead of
In bulk in advance. 1t becames
budget item instead of heavy spe-
cial expenditure annually.
A new gas-burning unit has been
developed that not only provides
the necessary heat for the radiation
system but also supplies the summer
demands for hot water. This makes
q definite saving in space in the
basement, because both units are
contained in the same furnace space
and require only one pilot light.
Every home owner should decide
now what can be done to make his
home more livable and less expen-
sive to maintain. Of paramount
Importance is adequate insulation.
Insulation Restricted.
OF course, the attic can be taken
care of with the insulation now on
the market in blanket form, but the
side walls in houses already built are
restricted to the form of insulation
that is blown in between the studs.
For new homes and attics of older
houses there are a number of
blanket-form insulation that can be
used. A new one on the market is
made from the staple crop of the
south-cotton.
This cotton insulation Is fame
proof and fire-resistant. 1t has been
treated so that it will Withstand a
temperature of more than 1,500 de-
grees Fahrenheit.
Another good quality Of cotton is
the fact that 1t will repel water and
not become saturated with it, This
reduces the danger, always present
In the water-abSorbent materials,
that the woodwork will become af-
fected by the moisture and that rot
will set up in the framework of the
building.
This insulation is free from attack
by vermin, rodents or fungi. More
over, 1t will not decay. 1t is odorless,
clean and free from dust. 1t is made
In blankets i the regulation stud
ding widths of 16 and "a inches and
IL can, Of course, be cut to any
length to fl into any house building
condition.
Residence an Advantage.
It has the advantage, also, that
no matter how much it is compressed
Its resiliency will bring it back to
the original thickness. These thick
nesses are from l to 35s inches. It's
hexibility will overcome any settling
of the building and will take up the
normal contraction and expansion
caused by differences in tempera-
ture. 1t should last as long as the
building.
There are several ways in which
this insulation is made. 1t is made
without any support or it can be
bought with an asphalt impregnated
paper backing. 1t is made, also,
with an aluminium backing which
gives 1t an added protection against
the penetration of cold in the win
ter and heat in the summer.
Most OF the bats that are backed
have = fiange on the side of the
papey, which makes it easy to pro-
vide a tight joint with the studding.
Cotton will not absorb heat, and,
therefore, 1t is more effective than
materials that will. 1t has, as well,
the advantage that in heating the
house in the winter 1t Is not neces-
sary to first offset the at absorb
ing qualities of the ins lation be-
fore the house itself feels the effects
Of warm radiators. This naturally
has an effect-a beneficial effect-on
the fuel bills.
Cotton insulation has an added
