Do you guys think a 1500W electric heater with a fan would heat my garage? It is detached, but appears to be very well insulated (during the recent -35C week, the coldest it ever got was -7C). I believe it's a standard double 20X20ft or very close to it. Ceilings are pretty low, maybe 9-10 feet. There is one large window as well but it doesn't open.
Originally the plan was to heat it 24/7 with Infra-red or a gas unit, but if the coldest it's going to get is -7C, that really isn't needed. What I do want is temporary heat for when I am working out there. Doesn't have to be a balmy 25C, I would be fine with 15-18C or so while I'm out there.
So, I think what I want is a powerful portable space heater. The "Mr. Heater" units look good, however I want to avoid gas if I can and buying/filling 1lb propane tanks all the time would be very annoying. Also, they removed the fan in 2018 so those models no longer blow air. I looked at the 'bullet' style heaters too but again they are all propane, and I don't know if you can even use them in a confined space since they would deplete all the oxygen.
I have an electrical panel in the garage, but no 240V as far as I can tell, and 1500W seems to be about the limit for electric 120V heaters. Would something like this heat my garage since its insulated, or am I wasting my time?: https://www.amazon.ca/Honeywell-Prof...0402794&sr=8-3
Plan B is to just get a full blown natural gas or electric heater installed on the ceiling but if I can get away with something more suited to temporary use and avoid any potential fire hazards associated with a permanent install, that seems to be the better choice for me.
