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 (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. The following
steps will help ensure 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 content
of the air.
3. Do not use an unvented room heater as the primary heat source.
