Smart...gald to know it!!! I thought all catalytic heaters were non-vented. I'll buy a book and sit in the corner for a while.

The vented catalytic heaters do remove moisture and are great. In other words, you will have less moisture from the human occupants and cooking if you use a vented catalytic heater than you will if you use a propex or carver. With my plat cat, i have virtually no condensation on the windows in the morning even with two occupants. The heater is venting the cabin all night. With the propex alone, there is condensation on the interior of the windows in the morning. steve
