It’s been awhile since we had to run our alde in very low temps and get the trailer warm. I feel like we would burn through a bottle in about 2-3 weeks though.
Overnight you can set the alde to a lower temp to prevent excess usage if you can get the right bedding (flannel) or you sleep warm. I have the added benefit that my wife sleeps super hot like an oven so we have the alde set to 50 overnight and when I wake up around 530, I turn it up to 70 and off around 8 or 9 am. We are in AZ currently, 70 during the days and high 30 at night.
I do absolutely recall that on electrical priority, the alde uses a high amount of electricity. So much so that we found it to be cheaper to run it off of propane only and fill the bottle every two-three weeks.
