Hi again...
I think I fixed the water leaking problem - I sealed some outdoor flue / chimney connections. As soon as it starts raining again I will see if there is still water coming into my chimney. If so, it must be the flue inlet itself. (the funny turning thing at the end of my flue)
The problem of smoke leaking into my room still is not under control: the last few days it's getting worse again. Actually it seems it was ok when I used a second hand cap and after I replaced this cap with my funny cap which moves / aligns by wind direction, it seems that the problem with smoke leaking when reloading is back again.
Oudoor temperature is around +2 degrees centigrade and windspeed is 1 Bft. Not much wind, but cold weather. So I would expect draft should be ok. After starting the fire with lots of smaller wood on the top and medium sized logs at the bottom there is a strong fire, white / yellow coloured, which tells me draft must be ok. There is a strong suction of flames that bend around the baffle plate. A strong noise of moving air can be heard, also 1 meter away from the stove when sitting in my sofa.
But As soon as the first load is burned, the top of the stove has reached around 500 Fahrenheit and there are not much flames, just hot coals. So I open the door slowly, taking some time, open it a bit more, very carefully, and I put 2 medium sized logs in the firebox as quick as possible and close the door.
Air inlets are opened at 100%. The logs ignite quickly and there is a yellow / white coloured strong flame. But just a few seconds later, the room starts to smell like smoke.
This problem seems to arise during the first reload. Most of the time, after that, the second and next reloads don't produce this smoke problem. It seems this problem was gone when I used the non-moving cap.
To me this is very frustrating and unpleasant as I have doubts about how healthy this is on the long term. I think the chimney is ok - it's around 6 meters vertical length and just a straight line, except the 90 degree t-piece and the horizontal part of 45 centimeters.
I still don't trust the baffle plate which puts a lot of air resistance on the system. Maybe it is calculated and ok according to the manufacturer - but I have my doubts about this baffle plate. When looking at some youtube videos and reading the importers comments, there is a message like: this modern stove puts high demands on your chimney system. I translate this to: this stove has a very high draft resistance compared to traditional stoves and therefore you should not use horizontal flue pipes, any 90 degree bends and only the top connection rather than the rear connection.
As I have tried everything I can come up with like pre-drying my wood, testing it on MC before using it (restricing wood to < 15% MC), checking wind and outdoor temperature, getting a hot as possible fire before the first reload, checking the chimney on draft by hearing and watching the flames and air movement, the only conclusion I can come up with is his is a very critical stove which only functions well on a chimney that has above average draft.
I will contact the seller (again), to ask what to do. I'm unsatisfied with the first reaction of the seller, just like the Duch Morsoe importer and the factory in Denmark itself: they all tell me that it's the chimney / flue and it's my own fault. They are quite sure about this. But I have big doubts if they are right. I don't say I didn't make an error myself, this could very well be the case - but I just doubt it as I looked at a lot of stoves and chimneys at friends places and no one has so much problems with smoke when reloading.
If the shop won't help, which I expect - I will hire an certified chimney sweeper and installer - to inspect my chimney - as a last resort.
But to be honest, I'm very unsatisfied with this modern stove.
I will replace the current cap:
...with this one (again), as the one below didn't show smoke leaking problems when refilling:
