Heatmor has a new furnace 350X that will heat 8000sqft that is replacing the 400 phase 1 and 2 models. This furnace output is the same as the 400dcss but more efficient. The firebox fits a 30in stick of wood and has 9 secondary flue heat transfer tubes. Using less wood to heat the same area.
I seen new ones and downloaded Manuel to scared to ask how much they are . leaning to wards 400css . I mastered the 200css
for 19 years and there dang good stoves . Dry oak below 30% is a match for the 200css and I'm sure 400css would be the same .
keeping ashes cleaned out is keey with these stoves . Mine don't smoke hardy at all just start up from cold . other wise all you get is heatwaves . so I don't get the whole smoke is the problem . I think its more of wet wood is the problem
I even tested if you put 3 dry oak 3 wet oak . you get steam for about 30 mins and right back to heatwaves . but I have quite a load on my stove at 5500sqft. So everything burns dam hot . That might be why I don't get much smoke . Be nice to burn less wood though .
