how is the garage insulation? would it be better to add some insulation ?
how many watts are the heaters you're planning on using?
Insulation is pretty good. I have a little to finish in wall bays, might be wrapped up tomorrow, then I need 1 more bundle of r30 to wrap up the tails of the of the roofline. So about 95% insulated. Building is house wrapped and taped. Ceiling is r30 and I plan on using metal siding to finish off the ceiling and wainscoting. Walls are r13 or r11(got killer deal on the r11 and wasn't enough of difference to justify not taking) then interior walls above wainscoting are old cedar fence boards.
Because roof isn't vented and I'm seeing some signs of moisture on backside of roof sheathing on north side after this last cold snap, I might talk to acquaintance that owns insulation company about cost to spray foam the roofline, then I'd reinstall the r30 Batts. Or I'm going to have to do some serious research on the venting options. Long story why they weren't added during construction. That's likely another thread. Short of it is, I have exposed rafter tails and thus haven't found viable option to draw air in from soffit area.
My ceiling heater is 5500w low with variables thermostat and 7500w on high.
I think the baseboards are both 1500w. I'm not looking for them being long term necessarily or doing anything other than helping bring the temps up faster. Is there anything hazardous I should worry about?
