The problem with my current stoves are multiple: lack of capacity in our primary stove upstairs, lack of efficiency in the upstairs stove <60%, problems controling the burn due to the stove being too leaky for our coal, and the ash pan/cabnet is nasty dirty.
In fairness, the TLC was never designed for bit coal, but it's what the salesman up here pushed, and we were new, not knowing what to look for.
The basement stove smokes out the door anytime it's open before 3 hours into the burn (6" collar, 6" SS lined 30' stack). The basement stove's ash pan/cabnet is worse to clean than the upstairs. I can shovel up to a 1/3 of a hod of ash that misses the pan every second load. And, no, I don't let ash pans overflow. Both stoves get a full dump with every new load.
But, the basement SF250 is nice and tight, very good at controlling the burn on our coal.
We're going to move to a coal boiler in the basement when I finish getting the radiators installed.
Due to the low BTU output of our coal, the upstairs stove requires 2 50lb loads a day, two ash dumps, two cleanings of the ash that spills into and out of the ash cabnet.
For the upstairs stove, a larger capacity higher efficiency stove will give us the ability to perform only one load a day, with only one ash dump and cleaning of a more tidy ash cabnet.
With the stove we're looking at for upstairs from DS, we'll get about 35% higher capacity in the firebox (that's 35% higher than the TLC's present volume after I built-up it's firebox with an extra row of firebrick), and a hopper that should hold close to another coal hod, which will get us to a 24 hour burn, even if the stove isn't more efficient. From discussions with DS and a few others, it appears their ash management system will be a significant improvement as well.
I'm not a coal expert, and I'm open to hearing anyones thoughts - after all, you guys were here for me when I just started burning 1.5 years ago - but I've been burning 24/7/365 for that time, been through about 24 tons total, and I'm ready risk some changes.
