WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a by-product of gas combustion. An
unvented room heater produces approximately one
(1) ounce (30ml) of water for every 1,000 BTUs
(.3KWs) of gas input per hour.
Unvented room heaters are recommended as supple-
mental heat (a room) rather than a primary heat
source (an entire house). In most supplemental heat
applications, the water vapor does not create a
problem. In most applications, the water vapor en-
hances the low humidity atmosphere experienced
during cold weather.
The following steps will help insure that water vapor
does not become a problem.
1. Be sure the heater is sized properly for the
application, including ample combustion air and
circulation air.
2. If high humidity is experienced, a dehumidifier
may be used to help lower the water vapor con-
tent of the air.
3. Do not use an unvented room heater as the pri-
mary heat source.
