So if a older house has vermiculite you just assume it’s asbestos then? I didn’t realize it was a contamination thing.No. Years back there was asbestos contamination of some vermiculite that came from a particular mine. That mine was shut down after considerable lawsuits.
Without testing, there is no way to know, but if it is from before 1990 it is likely to have some contamination. Vermiculite is a popular product still. It is used for insulation, insulation board, and also in nursery soil sometimes.So if a older house has vermiculite you just assume it’s asbestos then? I didn’t realize it was a contamination thing.
So you had a good hot fire for a bit that’s good. How full was the firebox? New stoves burn best if loaded clear full and allowed to burn all the way down. I use lots of small kindling to get the fire started top down from a cold start and on the bottom of reloading almost all the time.@jsmith_TCF: thanks for your suggestion. The top of the flue outlet is about the same level / height as the roof. But I think it will look ugly to have another piece of flue pipe extending 60 cm on top of the masonry pipe:

And would this modification guarantee a greatly improved draft? Tonight I lighted my stove and the first 30 min there was a strong and hot fire. I waited, as told by the lady of the stove shop, until all flames disappeared, to prevent smoke from leaking in my room. But the problem is that temperature has dropped by then to 250 F. I then put a log on the coals but it had difficulty catching fire. After a while I had to open the door to keep the flames going. Then the fire died. It feels like I have to time and prepare everything to a very strict schedule and practice in order to get not too much bad air in my room.
I contacted the Dutch Morsoe importer and they tell me the stove shop is correct - the chimney is not ok or my indoor ventilation is not ok. I will call him soon to talk about this issue. It has also to do with the "modern" "clean" technology of this stove.
To be honest, I'm losing confidence in this stove. It seems like a complicated thing to get a constant good draft in my situation.
The only thing I can come up with is putting a 82 cm piece of flexible double walled stainless steel liner on top of the current chimney just to temporarily test the effect of extending the current chimney and have it's top about 80 cm about the highest point of the roof.
Yes you want a moisture meter. Start a full load top down with lots of dry kindling. If you wood is 20% or less and you still have issues then it’s time to look into other things like chimney height, smoke tray/hood and re doing the connection. One thing at a time.Hi, thanks again for your replies.
@PaulOinMA: yes I can, but I prefer to do it myself and invest in such a device. Any advice on what type is recommended? Do things like permanent, liner built-in draft meters exist? Or is this overkill? If would think it could be a nice feature to be able to instantly read draft in order to decide to use the wood stove, or in my case, fall back on my wall heating.
@EbS-P: the stove wasn't fully loaded. I will try that as that seems to be what is advised in several instruction videos as well.
@velvetfoot: I always keep it in the "best operation" area, that is 260-460 F. I guess there is 1 top plate between the thermometer and the flames.
@MR. GLO: I bought the wood as (naturally) "dried". I don't know how long it dried. Should I invest in a moisture meter? (I try to restrict myself from buying too much electronic devices). The wood is stored outside in a 100% dry, venting wood shed. I reload at the end of the burn: I wait until all flames are gone. This is what the stove seller told me to do, and also several videos about how to properly use a EPA stove. Is this true? I get the idea that there is less (maybe almost none) smoke leaking into my room when loading on coals (and no flames). But yesterday I put a medium sized, cleaved log on the coals, not that big, about 10 cm thick I guess. It took several minutes to catch fire and then I observed smoke smell in my room. (both vents were 100% opened, door closed) Then I opened the door just a bit, but it didn't burn well. The problem is when waiting for all flames to be gone, temperature has dropped to 260 F. I think I had to put smaller pieces of wood on the coals.
Videos look ok But it’s hard to tell. Flames look lively. I was expecting to see more secondary combustion. but I have no real experience with this stove. How does your burning compare to this video. Amount of wood and flame pattern.? This one loks pretty reasonable.Hi, thanks for your new replies, I will respond on them soon.
@bigealta: good idea. I made a series of videos tonight. Here they are, in chronological order:
1. starting the fire, Swiss method, first time that I managed to start a fire this way, without newspapers. If I'm correct this is better as it produces less smoke than the other way around which I used until now (bigger pieces on top of smaller twigs and newspaper). Both air vents fully open, door slightly open as well:
2. After about 5 mins: I used small pieces of splitted pine wood, stacked on top of bigger (but still not so big) birch wood (2 pieces). On top of the pile I put twigs and also in betweek each layer. Both air vents still fully open, door closed (?).
3. After about 30 minutes: all wood except the biggest birch log has burnt down:
4. Just before the first refill: temperature dropped to 260 F before all flames disappeared. No visible smoke leaking to room, but smell in room (not smoke-smell, but coal smell?)
5. After first refill:
6. Just before second refill: coals are looking very nice?! Red glowing
7. Between first and second refill:
because I waited for the first refill for the flames to disappear, temperature dropped to 260F, which is 'creosote' area according to my thermometer. No visible smoke leaking into room, but after refill there is a clear smell, not smokey, but 'coal smell'. First cycle took around 1:15 hours, almost no temperature raise in room.
Second refill: more coals, more red / intense color, higher temp, still smell leaking in room, but not visible smoke leaking while refilling. Second cycle took less time, between 30-60 mins, much more heat in room, getting pleasant now
Third refill: lots of coals, (almost) no smell in room after refill. No visible smoke while refilling.
I can hear a clear sucking sound (draft), even at 3 meters distance from stove, when I concentrate and listen. Any idea after wachting the videos if things look ok or not? How about draft?
