We just got a new "Blaze King" Ultra, with gold door and dual fans (which are nice on sometimes, and very nice off sometimes). We got a double wall stainless steel chimeny, with 2-1/2" of insulation. The "stove pipe" from the stove to the chimney is non insulated double wall.
For your own safety, get the best chimney you can.
The Blaze King re-burns the gases and products of combustion with a catalytic re-burner. Because of the re-burner, it is 82.5% efficient, and has very little emissions.
The automatic thermostat is a joy. "The house controls the wood stove.", Francis the neighbour said. You fill it full with wood and it will burn efficiently for up to 47 hours on "low".
It's been a long time since we have had a thermostat on our wood stove.
Very happy with our lovely new stove, very.
