we have the firewarm 12kw stove, a picture to show you what its like
http://www.firesonline.com/acatalog/Firewarm_Multi_fuel_Stoves.html
We bought it in our local topline hardware shop for €500, alot cheaper than ebay or uk websites, I think a 6kw was about €375, there was a sale on though. Very reasonably priced. we have ours in the kitchen, have a steel woodburner in the sunroom, and have yet to purchase a stove for the presently used as a junkroom sitting room.
I actually thought, oh its very cheap, it must have crap airwash, but big surprise, its pretty good, cast iron (slower to heat up but gives out heat for longer than the wood burner). Actually if glass needs to be cleaned in the stove, the firewarm is easier to clean than the wood burner which cost €1200, so a big thumbs up.
In saying that though, I love the tall stoves, and wouldnt swop my woodburner as it really suits the sunroom. I would be tempted to get another firewarm for the sitting room, but's another room suited to a tall standalone stove and would go for a Nestor Martin steel mult-fuel for there when we have the money.
The firewarm really suits alcoves though, which is what is it in our house.
