Propane heaters failure at 30 degrees
On 2/25/19, I had methanol injected into my propane tank by the fine folks at Blue Star Gas Co in Phoenix, AZ. We traveled to Flagstaff, AZ (Elev 6909') to "test" the heaters in the frozen tundra of the mountains. As you may recall in Jan and Feb, all of my propane shut down when the outdoor temperature reached 30 degrees. As timing would have it, Flagstaff had a "warm spell" and it ONLY went down to 36 degrees at night. Unfortunately, at 5:00 AM, the heaters failed. However, the stove lit and stayed on which had not done when the propane failed in the past at 30 degrees. At 8:47, the heaters came on by themselves when the outside temperature rose to 39.7 degrees.
We have figured out what to do. No more winter camping! But I am still very interested in what everyone has to say.
