We've used our Enviro mini as the main source of heat in our house for more than 10 years, and it's still going strong. We've finally decided to upgrade the flooring in the "great room" where the mini resides, and I'm concerned that the built-in hearth pad will damage the new "luxury vinyl plank" (LVP) flooring that we're putting in. So, I'd like to have something under the mini to project the flooring, mostly to spread the weight. I don't want anything too thick, but other than that I'm not too particular. If you have any suggestions, let me know!
