I have had 3 medium splits going for 3 hours now. They are glowing bright and there no longer is too much flame jumping off of them. My thermomter has been at 550 for the last 2 1/2 hours. It is hard wood and one of them was a round. I would like to try to get the most out of the wood I have. If anyone has found an effective way of burning efficiently, please throw it out there. My stove shop came in yesterday and they think the one fan is bad. They took it with them and will be back to replace it. I feel like I am only getting half of what the stove has to offer. I am looking forward to getting to 100%. I am with woodsy. Keep it rolling.
