For the first time ever I have a house with no heat and cold weather coming
fast. I would love input from the group on the best type of temporary heat
for a remodel in progress. Because of the stage (drywall just going up) I
will be limited to kerosene or propane (20# tanks). I am interested in
safety, operating cost and equipment cost in that order. Would any of them
be acceptable (generally considered safe) to leave operating overnight with
no supervision?

TIA
