My Heritage, now burning well for 2 months. Recently, it seem to be more difficult getting in up to 500 on the top surface. 400 is pretty easy, but 500 comes a lot harder. I don't believe it to be the wood. Perhaps high winds recently creating too much draft. I am happy to say that my furnace did come on once for 28 hours from New Years eve to today when i let it go out. It was cold here on eastern Long Island with 50 mph Northwest winds.
Thanks
Happy New Year
