I was happy with the Mammoth Materials coal, especially for the price. It definitely has more ash than the old UAE Harmony coal, but there didn't seem to be any noticable difference in coal consumption and heat output. I didn't get any clinkers with the Mammoth coal, which was the one downside to the old UAE Harmony coal.BlackBetty06 wrote:Me and my dad just got 3 ton each of nut coal from mammoth. Still burning wood but hoping this burns good. I ended last year burning UAE Harmony but seemed to clinker on me when I was burning really hot. It had Great heat output though.
Report back once you switch to coal and let us know what you think!
