Im a long time wood burner and so is my father. My old all nighters door had a crack in the area that holds the wood off the air vents so I bought a DS160 last spring. I have been burning wood mainly oak on and off since temps got around 50 at night. I purchased 2 ton of nut coal to try since this stove burns both. Plus I'm looking for long burn times as poss with my job. ( I work 16 hrs on 8 off certain weeks). I have been pretty happy with the wood burning but still needed to load heavy 2x a day and a small load in the middle some days. Well I started a coal fire yesterday on top of a good bed of wood coals that took pretty fast. I had to read about coal because I'm new with burning it. It's been going for about 24 hrs now and all I did was shake it 1x and add some I top of the coals. This stuff burns long and hot. I have temp turned all the way down and it's still about 80 upstairs lol ( made it up to about 50 today and mid 39s at night) I like the constant heat its staying. Also it looks like I can get away with tending it 1x a day. This just seems to easy. Just a bucket of coal per day and I think I will have all the heat we need. It's also heating the dhw . I have had the elect off to it for about 2 weeks now. Have many of you tried coal? If so what is your thoughts on it? I may start just using wood for shoulder season burns and go to coal when it gets cold. I feel like I have been missing out all these years.
