Olympian WAVE 6 ...A review

Air on a highway is more hazardous than any heater, catalytic or not. Though it drops rapidly as you're moving away, 100-150ft is several times better already. If only they didn't build stupid little motels 50ft from highway.

All gas burning furnaces create condensation, homes or RV's.

Furnaces don't add water vapor to room air, burning process takes place outside.
Furnaces create condensation on cold windows not because they are propane-burning, but because you can see this condensation when air is getting warmer.

Catalytic propane heaters add very little water vapor, hardly worth discussing.

well, how much water from a Cat heater and it's effects depend a lot on location. In eastern oregon, normally dry, a cat heater isn't much of an issue, and in fact can make the dwelling more comfortable by rasing the RH to a comfort level.

Western Oregon, on the coast in the fall winter, the moisture added can lead to uncomfortable living and condensation when the RH outside is already high and still high inside.

The amount of water from combustion is slightly less than 1 gallon of water for every gallon of propane burned. Now on a wave 6 that's 15 hours or so of full heat, but combined with vapor from breathing, stove, a few wet clothes can aggrivate a marginal condition.

so, depending on location and local conditions, an unvented heater can be anything from a blessing in disquise to a pain in the butt for indoor humidity and condensation.

When we camp in the winter on the oregon coast pretty much need to run a dehumidifier to keep humidity level comfortable, let alone to avoid condensation. I typically pull 5-8 GALLONS of water out of the air every day with the dehumidifier, and that only keeps the RH down around 50%.
