  • <h4 class="dechead">On One Hand: There Are Minor Risks from CO and Humidity

    Like all ventless heating systems, a ventless propane heater lacks a chimney or flue, so it dumps its exhaust indoors. Propane heaters are extremely efficient, but incomplete combustion may produce carbon monoxide (CO), a toxic gas that can cause death. Water vapor, a more common exhaust product, can also damage the structure over the long term.

    On the Other: They Have an Outstanding Safety Record

    As the building industry points out, there's little if any danger of CO build-up if a ventless propane heater is properly installed and maintained and is equipped with an Oxygen Depletion Sensor (ODS). The ODS is designed to automatically switch off the unit if the ambient oxygen level falls too low. Adequate ventilation also deters CO and water vapor problems.

    Bottom Line

    A professionally installed and serviced ventless propane heater is safe, as long as it has an ODS and is used exclusively in a room with good circulation. Pre-1980 models, which might not contain an ODS, should not be used.
