We seem to be locked into a deep freeze, it as after all Canada, we have just got out of the winter habit over the last few years. It is so much like winter that the kids are playing hockey on the frozen pond at the end of our street. Not only that, yesterday a couple of the teen age boys shovelled our side walk on their way to the pond. Good kids, I have no idea who they are.
If you are freezing in your basement shop, Mr. Heater Big Buddy is an option to consider. It is rated for indoor use.
