That would essentially cut down the available area for air to get to burning coal and cut the output. Easily reversible for when it gets really cold out. Just watch your draft. If it doesn't work, it will only cost ya a few bucks for the fire brick.
I'm entering this thread a bit late in the game but C-12's suggestion works for me. If you could consider what I do in the warmer seasons. It works like a charm
check out the last link in my signature block. It's a crappy video but you'll get the idea. Really cheap and easy do do.http://nepacrossroads.com/about4018-15.html#p43355
