Hello, new here. Glad I found this site. First year using my boiler(CB 6048). I have it hooked up to 3 bldgs. All well insulated. One is 1000sf, and is only used on occasion--apt over a barn. One is a daytime use bldg 1800sf-, used M-F I drop the thermostat down to 60f in the evenings in that bldg. The last bldg is home used 24hrs 3000sf. I am running 3 pumps, 3 plate hx, and 4 forced air coils(2 in house). Our temps here have been 20F at night 30-40F during day the last week. I've been using mixed hard wood, split in various lengths, good deal from sawmill, deliverd by dumptruck. I just cleaned the boiler 4 days ago. I'm finding that the wood is burning so fast I'm getting a foot or more of red hot coals building up fast, hardly any ash yet. My temp is dropping as soon as the wood is changed to coals. I can stock it 11pm and by 7am a huge pile of red hot coals and the temp down to 150F. The pile of coals are making it harder to stack the wood and starting to block the vent. i must be doing something wrong... I've been doing some research and wonder if I should be using whole logs instead. Unfortunealty I dont have any reserve stock, so I'm not sure if I'll be able to get seasoned wood. I will certainly begin stockpiling now for following years. Any hints or any advice or pointers would be greatly appreciated for this newbie. Thanks!!
