Chippy,
A good friend of mine has a freestanding Woodburner in an opened up chimney breast in a two up two down sized house. He uses one of the fans on top of his stove to circulate the heat. He says without it, it is slower to heat the room, and he thinks the walls that surround the stove soak up the heat. He says if he had his time again he would make the recess for the stove much larger.
If you are used to an open coal fire, then you’ll really notice the difference with a stove. Generally speaking around 75% of the heat off an open fire goes up the flue. With a stove they radiate around 75% of the heat generated.
I used to test industrial emissions for a living, and found that sites that used pallet wood as a fuel had corrosion problems on the exhaust and stack. We suspected that the wood contained chlorinated compounds and generated gaseous hydrogen chloride that attacked the steel flue. I would say if you are going to the expense of having a flexible liner put down your flue, then purchase the highest grade you can afford.
Also note that wood burns far better on a bed of ash, so it is best not to clean out the stove on a daily basis. I assume that with your existing coal fire you clean it out daily.
When you get your stove installed you have to leave the installation cold for a few days to allow the fixing / jointing cements etc to cure.
After this it is best to have 4 small fires before you use the stove in earnest.
We had a small fire of a few sticks and a firefighter, and lit this, let it burn through and then go out. Later that day we had a similar fire, but added some extra sticks once the first lot had burnt through. Next day we did the same and then added a couple of very small logs, then once burnt through we let it go out. Next day we did similar, but added 2 charges of logs. This is done to allow the stove get used to expanding and contracting. If you go for it with a full on fire from first installation you risk cracking the casing of stove.
The best way to clean the glass on the stove, when cold, is to get a piece of damp kitchen paper and dip it in the fire ash, and then wipe the inside glass with this. Take it off with a dry piece of kitchen paper.
As for pets and their love of a Woodburner, then please see evidence below.
