[drg5490]

I've searched and checkd the mfg website but can't find whats the lowest outside temp for the unit to provide heat...anybody know? Also those that have run these in winter does the heat work fairly well? ...I know lots of variable to it just wanted a general idea..,Thanks

When it gets down +20f they are pretty much done.

while buying mine I vaguely remember seeing something that said 5 degrees. but I think that's a sliding scale. so at say 50 you get 12kbtu heating, 40 is 10, 5 is probably like 1kbtu. My average winter temp is actually like 40 so hoping I can use mine a lot.
