Oh and yes the king is only rated for 51000 btus but that is for 12 hrs of constant 51000 btus. If you open up the thermostat more it will put out more heat than that.
That is on high with the bypass closed I talked to BK themselves. I had the local dealer come out and put the new cat in and see how we were operating it to see if it was operator error. After the new cat was installed it did give off a little more heat in the bypass mode. But however it still does not give off hardly any heat and the dealer said the stove is doing exactly what it is supposed to. And yes of course we burn seasoned wood the dealer was surprised at how low of a moisture content it has. All I know is with the BK on high and the bypass closed I can stoke it up at midnight and by 8 there will be a nice coal bed but the house is down in the low 60's. With the fisher I will stoke it up and 8 hours later there might be fewer coals than the BK but enough to start small wood again and the house is in the low 70's.
