Hi all, happy 2019! I am in the near-north suburbs of Chicago. We purchased a home from a family who had lived and owned from the 1960's and as luck would have it, they had a Kent Tile stove in the sun room. Must have been cutting edge gadget people in their day. Needless to say I went from 'what is that' to passionate user very quickly. What a remarkable device. I burn Oak exclusively as it lasts the longest and maintains the heat the best from my experience. It's been a pleasure to read about other owners' experiences as this is easy to become really enthusiastic about. What is most interesting and impressive is that fact that it is pretty much indestructible given its age and clearly regular use. You can fill it with wood to the top and there is no exterior-indoor smoke whatsoever. Just a slow, warm burn that heats an all-glass sun room and the adjacent family room on cold winter days. We have a large wood burning fireplace that gives off half the heat.
