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 (.3 kw) of gas input
per hour. An unvented room heater is recommended as a supplemental heater (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 the proper size for the application, including adequate
combustion air and circulation air.
2. If there is high humidity, 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.
