WATER VAPOR: A BY-PRODUCT OF UNVENTED ROOM HEATERS
Water vapor is a
Unvented room heaters must be used 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 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 content of the air.
3.Do not use an unvented room heater as the primary heat source (an entire house).
