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
