With an infrared ceiling-mounted heater, it should be at least 24” far off the back and side walls while 7’ of clearance between itself and the floor. Besides, keep the heater at least 72” between any combustible items in the room and its bottom.
If you ask for more than one, leave 36” more between them.
With a forced-air heater, it must be set up at the coldest back corner of the garage and in the safety space zone between the ceiling and the heater (measured by deducting the heater’s height and another 4” from the ceiling’s).
Besides, ensure it offers 6’ of clearance between itself and the floor.
Is it cheaper to heat one room with electric heater?
It depends on three things:
