Packs a lot of heat for such a small device
Review by Shaun - Cask Woodworking

I was quite surprised at just how much heat this little cordless unit could produce. 35,000 BTU's is perfect for a two car garage or workshop of similar size. As a hobbyist woodworker in Canada, there are only a few months that we don't require heat, with the long winters, being out in the garage is near impossible without some kind of heat source. Being cordless I wasn't sure how it would perform. Again was surprised and pleased. I did a test for 30 minutes to see how warm it would get starting from 6c. Within 30 minutes we got up to 14c and with that provided a comfortable atmosphere for which I could work in. I had the garage door open a crack just for ventilation, however, no other smells were emitted from the device (beyond the first two burns as it needed to burn off the factory oil on the element). The price and value you get for this little guy is bang on and again a great addition to a 2 car garage workshop.
