In anticipation of the coming cold spell I ordered a Dimplex #DGWH4031 4000-Watt Garage/Workshop Heater from Amazon last week. It arrived yesterday and I installed it using my table saw 220 line. When I turned it on , the shop was 45 degrees, two hours later it was 63 degrees. I was looking at the Dayton G73 but this one was half the price. I mounted it about 6' high on wood storage shelf.
