So I bought this a few months ago, but have only recently gotten it in and working. I did a DIY install, and this stove was pretty easy to install, and was signed off by building control.
First the positives: The stove is well made, solid and looks really good. I was really happy with it when it arrived. It was well packaged and as mentioned easy to install. At first, I was skeptical if this stove was actually an 8kw, as its the same size as many 5kw stoves I have seen. I think the main difference is the size of firebox. You can easily get between 4 - 5 meduim sized logs in at once, although this would be running at max. I'm running it with 2 - 3 logs at a time. The heat output is really good, and warms the room quckly.
Negatives: Unfortunatly there are negatives with this stove, but they aren't deal breakers. Firstly, the airwash. I can see the purpose of the airwash system, and it is part of the reason I bought this stove, but for me, it isn't that impressive. I always run my stove up to temerature, and leave the airwash open but the glass always needs cleaning the next day. An airwash doesn't eleminate the need to clean the glass, but it should limit the number of times you need to clean it. Sometimes unseasoned wood can cause this, but I am burning wood at a moisture level of 10 - 11%, so I am dissapointed with this system. Secondly, the primary vent "the one on the door" actually causes damage to the paint. The bolt holding the vent together, when reasonably tight, drags along the outter edge of the stove, removing the paint, which I find frustrating. The bolt holding this vent together is also perminantly loose, which I find slightly unusual. It is a balancing act to keep it lose enough not to scratch the paint and tight enough that it doesn't come off mid burn.
Overall this is a really good mid range stove, and I would recommend. My negative points might not bother some people, but they may help you decide if the stove is right for you.
