7th year of heating with Lange 6302k

[Morso1bo]

In the seven years of ownership this stove has continued to provide reliable heating for a 200+ year old cape in northern New England. The oven is great for reheating food and making corn bread. It’s main drawback is that it really soots up the the chimney compared to my old Moro’s 1BO squirrel stove.

It's a beautiful classic stove. The top part robs more heat from the exhaust, but it also cools down the flue gases. Once they drop below about 250º these gases start condensing in the chimney.

What temperature do you typically read on the flue pipe? What size chimney liner is the stove vented into?

 

[Morso1bo]

Thanks. The flue is a 6” opening. The temperature on the flue pipe typically reads between 250-350 degrees when the stove is really going. It would be a struggle to get it to go much hotter.

Ok, I'm darkly jealous. Beautiful old stove!

Thanks defiant3. It is dark green enamel and really throws out serious heat. It is a craigslist find.

That is an ok surface flue temp. There might be a lot of cooling in the chimney. What does the 6" opening dump into? Is there a stainless 6" liner in the chimney or is it clay tile lined? If clay tile, what is the ID? Is this an interior or exterior chimney?

Still, the Morso 1bo has a similar design so it makes one wonder what the difference is. Is the Morso on a different chimney setup? Have you been burning less seasoned wood?

The stove vents into a stainless steel lined interior brick chimney. The Morso was vented out the same chimney years ago. I think the s flow of the Langes exhaust is what really extracts the heat from the gasses. It heats considerably more than the Morso did. The wood is seasoned for a year which definitely helps the chimney stay cleaner. After a season the Morso would deposit a large coffee can of grey, dry ash after sweeping chimney. The Lange leaves at least two large coffee cans of black, greasy soot in the chimney clean out after sweeping.

Forgot to mention that my old Morso would run at a much higher flue temperature about 400 to 450 degrees.

Maybe you were having to push the Morso a bit harder to heat the house?

 

[Morso1bo]

I’ll bet I was. I think it let more heat out through the chimney
