WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM
Water vapor is a by-product of gas combus-
tion. An unvented room heater produces ap-
proximately 1 ounce (30 ml) of water for every
1,000 BTUs (0.3 KWs) of gas input per hour.
Unvented room heaters are recommended
as supplemental 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 enhances
the low humidity atmosphere experienced
during cold weather.
