Hey everyone, we just installed a Saey Bremen 1 at my Dad's house and we can't seem to get hardly any heat out of it.
The stove uses a side knob to manually adjust the airflow underneath the grate, it has an adjustable width hopper, the inside is a "basket" style to hold the coal measuring about 20" wide x 8" front to back and 6" deep, it has a flat round shaker grate and the rest of the flat grate actually rotates back and forth to help with cleaning, and there is one other half turn air adjustment knob behind the ash door. We are burning nut coal with it.
We started a wood fire and had the single wall chimney pipe temp up to about 250 degrees. Our draft is set to -.05 which is good according to the manual. We added coal and got it burning but we were never really able to ramp the fire up to put out any heat. The side knob was fully open and we even opened the ash pan door. The stove pipe comes down to about 120-140 degrees and just sits there with the stove hardly putting out any heat.
Does anyone know anything about these stoves or have any general thoughts on how to make this thing put out some heat? I'm thinking of removing the hopper in case it is becoming too much of a baffle and diverting the airflow, or maybe try pea coal.

What size coal are you using and is there any way air can bypass the grates? I don't add coal to a new fire until probe in stackis over 600 have some coals from the wood and a roaring fire. Coal has to be just short or 1200 to light off. 250 in stack is ice cold why would it burn?

Air will bypass the coal until the coal bed is above those vertical slots in the fire pot, all around. You must fairly rapidly get the coal bed above those slots, then fill the hopper. You will get plenty of heat then.

You must plan on helping that grate to clear ash. A flat poker to slice just above the grate. Without that the stove will become ash bound in less than a week.

Close those secondary air holes between the doors as well.

Ddahlgren, we are using nut coal and yes I agree, we would definitely like to get it hotter before adding the coal but we were having trouble even with the wood, I'm gonna go over there again and work with it some more.

Franco, the only possible manual over air adjustment we can find would possibly be that knob behind the ash pan door. I can't really see where it goes but can't think of anywhere else it would go.
Good point about getting the coal above those slots, I see what you are saying about the air bypassing going through the coal and just going up and out, I will make sure we get them covered up.
It came with a small rod for slicing/poking so we will definitely be doing that too once we start getting it figured out.

I will see what I can get it to do tonight, thanks

I see what looks to be four half inch holes between the doors, which I assume to be secondary air.

Find out about that knob and what it does.

Verify that the side knob is letting air in below the grate.

Franco you are correct, the front plate has several half holes across from side to side that go down to the ash pan area, so those create the over air when its full.

That knob just goes into the ash pan/under grate area, not creating any over air. I assume it's just for additional air underneath.

Are you having any success or continued failure with this stove? I can possibly help but need to know what's been going on since your last post. I have much experience with this type of stove and will say as I think Franco also mentioned that you need a deep coal bed built up to, and filled by, the full hopper ( your photo indicates a fire much too small and shallow if I'm seeing it correctly) and you must master de-ashing with the slice tool for efficient and trouble free burn.(for what it's worth I quit shaking my grate several years ago and only use the slice which is way more effective imo) Let me know and maybe I can help diagnose if you have not got it performing to suit you yet. That stove should burn 500 face temp with no problems. Anything over that and youre asking for trouble. These are definitely space heaters not whole house stoves although they are capable of a lot of heat. they are phenomenal for in the living room to supplement another heat source but are not designed to be ramped up like brick and blower stoves such as Harman Russo and Hitzer etc. which you can crank to 700 and then use a constant blower which drops 200 of that right off the stove immediately in burning hot air.
Pea is easier to control once you're experienced but CLEAN nut will be the easiest to burn initially until you get the hang of it because of the de-ash learning curve these have. My problem with nut is that it often has a lot of fines mixed in because it's the least consistent of the coal sorts. Fines and dust will make burning a real pain as they choke out even a clean new fire. If you are ever battling really dirty nut coal filled with fines and dust you can hand sort a good bucket load to get going and the you have to figure out a cleaning method such as filtering through a big screen bucket with 1/2 in holes. My stove will perform poorly without the hopper full unless I remove it and just load it deep. I won't dump coal in my hopper if it's dirty with sediment fines and dust. I'm talking visible loose and flowing in the mix. all coal is obviously dirty! Lol
These top hopper European stoves are designed to operate I'd say on average of 275 to 425 face temp ideally. Give or take. I can run mine for 2 days at 225 to 250 on one hopper. 500 will need filled twice a day at least. Hope this helps

The stove is double wall, intended to circulate the hot air, so the outer skin will be cooler than a radiant stove. Be sure to clean any interior flue passages in the stove. It should achieve a full glowing bed of coal. Once started fill coal basket completely. The hopper should do that automatically. If it does not, check if the height is adjustable. You might find that pea coal will better close off those slots running up the sides of the coal basket. Until coal is above them air can bypass the coal bed.

I have done all that and seem to get barely any put top of stove right now is running at 200 f.. also. I was looking closer at the stove. There are 4 holes above the gate the two outside ones have screws in them. The two middle ones do not.. what is the purpose of these holes. Should I take them out or put two more in

These stoves will have ash clearing problems unless you use the slicing poker well. Concentrate on getting a full bed burning from side to side. Then judge heat output. I doubt closing those holes will make a difference.

I did a double look at my damper and it seems that it stays wide open even with it set i did close it off just to see what it would do that was 3 hours ago checking it every 15 mins or so just to be safe. Now it's staying steady at 350 400 face temp the flue pipe its around 150

Looks like a good full fire. If the damper was limiting draft, that could have been the problem
