m be easily controlled. The health of the family and the
ability to live in a satisfactory manner will depend to a considerable
extent upon the method of heating the home, especially in cold climates.

Particular care should be taken to make sure that whatever type of heating
is employed is adequate in size. It is more economical to operate a heater
that is somewhat oversized than to "rush" one which cannot easily maintain
a comfortable temperature in cold weather. Heating engineers and
contractors are available to furnish information on heating costs in every
locality. The generally used types of heating include stoves, circulator
heaters, warm air, hot water and steam systems, and fireplaces.
Specialists of the United States Department of Agriculture have developed
a great deal of information to enable the home owner to cope with the
heating problems in a practical manner. It is estimated by the department
that if a two-pipe hot-water system for a six-room house costs $500, the
other systems for the same house ordinarily would cost about as follows:

Two-pipe vapor system $600
One-pipe steam system $400
A piped warm air furnace $260
Pipeless furnace $140
Circulator heater or stove $ 60

Of course, these systems vary in efficiency and in providing comfort as
much as they vary in cost, but these estimates will provide the home
owner with an idea of the outlay for taking care of the heating problem.

The ability to maintain a satisfactory temperature depends as much upon
the construction of the house as upon the heating apparatus itself. Heat
is readily lost through walls, roofs and windows. Most houses can be made
more comfortable at small cost by applying insulation or by correcting
defects in construction. The use of storm doors or storm vestibules where
doors are frequently opened to the out-of-doors will prevent drafts and
conserve heat. Metal weather stripping is the most effective means of
preventing air leaks around windows and doors and making the entire house
weather-tight.

The fuel that is used will depend upon the type of furnace and the
relative prices prevailing for different kinds. Recent developments in oil
heating bring this fuel in close competition from the standpoint of
economy with coal or coke. Oil is particularly adaptable as a source of
fuel in homes in the country since tank trucks can readily deliver oil to
the ho
