Personally I liked the Stove because it was cheap and did the job I needed, but read Dave’s comments so you get a complete picture.
I have just been reading your assessment of the Winther Brown stove to see if it matched my own. It doesn't! I bought and fitted the same model 12 months ago but I bought mine online and unseen - big mistake. I do have a larger Franco Belge stove in another room so I am able to make a comparison based on my experience.
No expensive fire bricks to replace;
It does give off a good heat when burning coal.
You alluded to this one - the grate has a very low fence at the front and you have to be very careful when adding fuel to make sure it stays where it's put and doesn't fall out. It is especially risky when opening the door in case a burning log or coal might fall. I note that you use a fire lighter so you avoid the problem that I have when laying the fire. I use a layer of paper topped off with the kindling and this is practically impossible to keep in place due to the low height of the fence; The ash pan is totally inadequate. It is far too small and, to make matters worse, is open ended. There isn't really any point in using it. It makes such a mess when emptying the ashes.
I wouldn't recommend this stove to anyone - even somebody I didn't like - it is that bad. I long for the day when the glass cracks or the seals go so I will have an excuse to weigh it in for scrap and buy a proper stove. I hope that you won't be offended by my condemnation of something of which you obviously approve but I just wanted to take the opportunity to express my opinion.
