Bill Brown, of Grass Roots Energy Inc. in Wauconda IL, had watched the masonry heater industry for several years before deciding that it was time to get involved with Temp-Cast. We had talked to Bill every year at our annual industry show in various cities around the USA, but it likely took the glowing recommendation about Temp-Cast from one of Bill’s own customers to seal the deal. http://www.tempcast.com/workshop.html
