So are u saying u think the blaze would or would not do the job adequately?I have an old VC Defiant in the basement and can get the thing extremely hot very quickly. When I do this heat will rush upstairs like you are saying.
This morning I fired it up and left it on a lower setting. It is taking longer but the heat is still being pushed upstairs.
With the Blaze King you will be able to keep the stove going for longer and maintain the draft to the rest of the house without first waiting for the stove room and its path upstairs to heat up slowly.
When I allow the stove downstairs to be cooler the house becomes a more even temperature more quickly than if I try to heat it up faster.
I do not really think they are comparable stoves in terms of heating capacity or function.
