Hello all, I have been lurking for a while now and thought it was time to join in. I bought a used (2005) Harman in October and have been using it for my main heat source ever since. The info I have picked up on this forum has been priceless. Thank you all for that. So far 1 ton of Pennywise and a ton of Uncle Jeds cold remedy and absolutly no problems with my stove.
