I own a pacemaster silver XT elliptical. I am wondering if it's possible to store it in my unheated garage. I'm in Colorado, so we do get snow, outside temps reach -10c (14f). But while the garage is unheated, it is attached to the house and I assume will stay warmer than outside temps at least a little. My plan would be to simply use a space heater to warm the garage to a comfortable temperature when I wish to work out. Is this safe for the machine? I don't want to damage it with temperatures that are too low.
