While everyone has offered thoughtful and appreciated advice to help this newbie solve the problem the suggestion of simply buying a new heater when I can afford (?!) to is not helpful nor considerate.

The Weso stoves are among the most attractive, and, I think worth taking the trouble to make them work well.

I give a good shake when refilling but I guess I must do a more thorough job. The shakers don't do much shaking (poor design). I don't do this all the time but the most effective way to clear the bottom of the box is to open the barrier door and get a shovel or a long poker in there and scrape the clinkers into the awaiting half pulled out ash pan. Kinda dangerous and damn hot!!
Tell us more of these clinkers. :?:

mc G- The "clinkers" are just like raw coal nuts -hard but they're grey- partially burned (?) At the bottom of the grate there was some soft ash and stringy, knarled pieces of crud. About 3" higher from the grate to the top of the pile the pieces became more and more consolidated (nuts but gray and solid).

You could be mistaking partially unburnt coal for clinkers. Is your ash "red" as in a pinkish brown color or "white" as in no color at all?

Red ash tends to cause clinkers but not so much with white ash.

Can you post a picture of the ashes in the ash pan? My old Buderus was very similar to your Weso. European stoves are different, I am not sure what the fuel is like in Europe, where these stoves are born. They have been burning many years before America was.

Knowing this now will likely change some of earlier opinions.

It is so crucial to know all the pertenate facts from the beginning. :idea:

The ashes are white- no hint of red, pink or brown. The unmarked bags of nut are from Cranston Coal in RI . Maybe someone local to RI/eastern MA on the forum who uses Cranston's coal knows from where it comes.
We'll have to wait til tamara for a photo of what ash I get in the morning- but it's white with a few very small pieces of burnt coal. All day long today I've been running the Weso on Primary 1 of 5 with the secondary on "0" -(the lowest setting) which allows a circular opening of about 3/8" dia. Everything is fine- I'll toss in 2 or 3 small shovel fulls every 3 hrs. of so to keep the coal level even with the top of the front barrier fence. I shake b4 loading and slice from underneath and poke from above. Not much ash is produced- maybe 3/8" or less in 4 hrs. Ash pan about 11X 8

What is the correct definition of a clinker? I thought clinkers were partially burned pieces of coal. Guess not!

Clinkers are fused ash. Ash can get hot to the point is solidifies into hard nuggets.
"Red ash" coal usually has a clinkering tendency, especially when running a hot fire.
"white ash" coal doesn't normally have a problem with clinkers but can under the right circumstances.

That tending schedule is too frequent. During normal operation, a 12 hour tending schedule should be good. That's if it is shaken and loaded properly, but hopefully we can help you with that part.. :)

Now I know what clinkers are!! As to clinkers- I'll get a few (2 or 3) in the ash pan occasionally.
As to tending- I just do it to occupy myself while walking thru the living room. I realize that it's not necessary to keep it full all the time.

With all do respect to other posts, these European stoves with their shaker grates benefit more with frequent consistent shaking intervals than rocker grates. Taking into consideration not to drop too many red burning ashes. They also suffer from dead spots due to the right and left motion.

If possible to you or to an other member to send some photos showing the grate system.
And as my friend F.Fred said, slope the coal upper at the back could probably help.
