I have this heater mounted from my garage ceiling but it's to high to reach the thermostat control without standing on a step stool. I don't want to lower the unit so I'm thinking about taking the thermostat out of the unit and extending the wiring about 3 1/2 feet and mount it on garage wall. I haven't looked in the unit yet to check out how it's wired in so it might not even be feasible. But if I could would this create any problem in terms of resistance etc. ?
