INDIRECT HEATING

Indirect heating is provided by passing air over radiators attached to
the ceiling of the basement, thence to the upper rooms. In the
"direct-indirect" system the radiators are placed in the partition
walls of the rooms they are to heat, the cold air being brought through
a duct and, being heated, passing into the rooms. These two systems
are economical of space and afford provision for excellent ventilation.
They are considerably more expensive, however, than the direct system,
which involves exposed radiators.

Radiators are now constructed in many different forms, to fit under
windows, in corners, in fireplaces, under cabinets, and so on. Much
effort has been directed also toward relieving their painful ugliness,
and if of a neat design appropriately colored they need not be a
serious blot upon the decorative scheme of a room.

Radiators, in the direct system, should be placed far enough from the
walls to permit free circulation over the heating surfaces, and should
not be directly covered at the top. Ordinarily there are good reasons
for putting them near the more exposed places, such as windows and
outer doors. As both steam and hot water furnish a dry heat, provision
should be made in every room for evaporation of water.



SUMMARY

With no prejudice against good furnaces, it may be said that hot water
apparently affords the greatest possibilities for comfort and
