Anyone using the Mr. Heater "Journey" catalytic heaters?
Looks very similar to the Camco Olympian heaters - Mr. Heater Journey Catalytic Heaters (Not to be confused with the non-catalytic "Buddy" heaters) Anyone using one? Like it?

In residential heating, a typical recommendation is 1 square inch of opening for every 4,000 BTUs of heater.
Using that guideline, a 3,000 BTU catalytic heater would need at least 0.75 square inches.
So, if your window is 12 inches high, you would only need to crack it open by about 1/16th of an inch to get that 0.75 square inches.
Add in another 100% safety margin, and you're still at only 1/8th of an inch.
Our awning window is about 18" x 14". Considering its an awning you can only use the 14" once, so about 32" in length times 1/4" is 8 square inches. When I was researching catalytic heaters I remember 4-6 square inches per 1000 btu's. At 1,500 btu's I need 6-9 square inches. Remember we're talking about an indoor catalytic heater, not residential heating.
The Weber runs for about 8-10 hours on .8# of propane. I waste too much gas trying to fill those Flame King cylinders to one pound and .8 pounds works for us.
Enjoy,
