Large Hot Water System Efficiency

I will double check to make sure those are hanging... i'm almost certain they are. If they are then I guess your right. about the only other thing it could be is bad coal. Thanks for your help and patience.

This was an old post from last year, but since then I've made some changes to the system. I have a good HVAC person, but I would still like to get a pro(someone from the site that knows what's going on) to come take a look at my set up. As efficient of a machine as everyone says this is, I can't seem to get it dialed in. So if any of you pros are in the Clearfield Area (16830) please send me a pm and let me know. I'm more than willing to pay a reasonable fee. I just figured with hunting season right around the corner someone might be making a trip to Bob's army and navy or Grice's Gun shop (both no more than 2 miles from my house). Also dinner on me at Denny's Beer Barrel Pub. WORLDS LARGEST BURGER...
