I read on the right and left that invicta stove gives off smoke enormously when opening the door to charge this one ..... Would there he qqun which would have you already purchased or well have also had echoes on this little problem ?? people who complain say they are forced to repaint the ceiling every year
This problem of smoke emerging by opening the door exists on all the inserts and stoves at different levels, depending on the draft, the VMC in operation or not, the geometry above the door of the stove, as a chimney lintel advancing strongly above the door of an insert (my personal case) or not for a stove with no protection above the door!
For me, with insert, the lintel needs to be cleaned a little late winter, but not the ceiling!
To sweep the interior, once cold, I put a plastic sail around the fireplace and on the floor to avoid the dispersion of soot, much worse than opening the door to reload the wood.
To block this problem requires advanced above the stove receiving smoke swirling when opening the door.
A good chimney draft decreases the smoke, but the wind sometimes prevents the chimney to draw correctly.
Otherwise, everything depends on the insulation of your home 135m2, but a house of 60 years 70, quite usual, not well insulated according to current standards, this stove 14KW seems low, unless you have another heating, especially in the Vosges, not warm in winter (in altitude ??). becoming steady, reduced on 10h, it does not 14KW. The heat exchanger seems low, a simple flue gas deflector?
Personally, near Paris, less cold, I have a stronger insert so full of logs, especially with an internal heat exchanger with external circulator sending hot air into the upstairs bedrooms, which can quickly heat the room if necessary arriving a weekend. !!
Personally I would not accept your stove system without such an exchanger and circulating fast hot air heat for a home 135m2 to 2 levels! or with central heating boiler.
This is a far superior comfort.
Your stove heats only by natural convection, which is already long for you but low on many levels, especially if your home is poorly insulated (before 1990).
Your stove simple structure (single deflector in pdf) seems to have a good heat exchanger even if his performance reaches 80%, but what power 14KW, or at a reduced speed on 10h, (power how 3 to 5KW ??? because you load wood, open to 10h and 14 KW is for ??? 2h and 10h is 10 / 2 5 time = less power or 3KW ????? ??). The seller will have no answer to such basic questions !!
If you can not reload often, (to work on 8 absence 10h), this stove may be much lower, in the Vosges.
Any heater performed well at low speed because the fumes not stand too hot, having time to cool.
If you have a long discharge pipe smoke in your room, the performance will be better, the tube serving exchanger.
My insert has a double baffle plates 3, boring removed for sweep, because we swim in soot, but the exchanger is much better, yet insufficient maximum power !!
Take a look at the ease of disassembly and cleaning of this soot-filled baffle. We have the impression that nothing is planned on the map and you will fill your stay with soot!
The ashtray seems very small, too thin !! You will not stop to empty the ashes, especially with not perfectly dry wood and put everywhere, as it is very thin and light ashes flying everywhere.
To block the fumes that come out, opening the door, you have a very good draft with air inlets, no VMC too strong, nor winds, and strong advanced above the door (as Mantel) that deflects and receives the hot smoke that seek to rise, instead of the ceiling.
A large metal plate is suitable.
Apart from the aesthetics, I'm not excited by this choice of stove, at least for my home.
