We love this unit’s compact size and retro good looks, but it took just short of half-an-hour to get our garage up to temperature. However, in a better-sealed workshop, it would have plenty of advantages. It was extremely quiet, there are two output settings and there’s even a fan for summer use. An integral thermostat means you can set the unit and forget about it. And, being electric, you don’t need to worry about ventilating fumes away. A very worthy Recommended buy.
