What kind of burn times are those of who have similar US Stove units getting ? I have a clayton 1600 that was in the house when we bought it, heats roughly 2500 sq ft thats ducted through the house. Unit has the forced draft kit but we only use it when starting up or if i add a freah load of coal in it, burns great with out it. I keep my settings on the limit switch at 150 on 125 off ,so far has done great job keeping house warm with the somewhat cold temps weve had. Im burning all seasoned mixed hardwood cut to 24" and if i load the stove with 6-7 pieces im lucky to get 5 hrs out of it before a new load is needed if i go past 6 hrs its in need of a restart. I have been mixing a load of soft coal in with it for overnight or if we plan to be away for a good while and i can stretch the time before tending a few more hours this way. Just curious to see what is average with these units because it is eating throigh wood quicker than a regular wood stove that i am used to!
