So my Quadra Fire takes pumice bricks. ..

JA600L · Feb 2, 2014

I had a lot of cracked and broken fire bricks so I let the stove die down and removed them. Upon contacting my dealer I found out that all of the side and back bricks need to be pumice. So I spent a small fortune and replaced them all. I put regular brick in the bottom. My question is will I notice any difference after replacing these? The stove is about 8 years old and had the original bricks. They were much thinner and cracked with lots of gaps before. Maybe I'm just trying to justify the money I spent.

IMHO, you will probably notice more complete combustion as the firebricks tend to allow less heat to get thru the sides where they're located & force the heat to stay in the combustion chamber. Whether or not you'll be able to justify the costs, I can't say. I will say that I think your dealer sold you a line of crap. A firebrick, whether clay or pumice, will do the same thing & work the same way. If they are a standard "split" brick, they are the same size & the only differences are the weight & the price. Clay split bricks are about 2 bucks (+/-) each. You probably paid more for pumice...

Note that you can get pumice brick for a better price if the dealer is charging a lot. Pumice firebrick has a higher insulation value which should keep the firebox hotter, ensuring more complete combustion. Like Bob said though, regular firebrick is going to work too.

The biggest thing that I noticed is a more efficient complete burn. I load the stove full and it burns all night. I have plenty of coals for a relight and almost no ash. Before it was big chunks of coals and lots of ash.

I know that hearthstone and others use soapstone fire brick and I like the gentle heating cycle that they provide. I have also seen that soapstone bricks can be purchased and are the same size as other firebrick. Could one substitute soapstone for conventional fire brick in a non-hearthstone stove?

When I went to the local quadrafire store I noticed the insert they had running was hot as hates and unpleasant to be around. Not so with the hearthstone. I attributed this to the firebrick differences. I could be wrong.

So in my Quad 2 of the back bricks have a hole in them for start-up air tubes....can I just drill out holes in regular pumice bricks? The link Green gave has a price a fraction of what Quadrafire charges

I drilled in hole in a standard firebrick when I had my Quad. I can't believe the pumice brick would be that much harder.

I would suggest more of a hole saw, than a drill bit (yes I have bits that size). A hole saw will have less chance of cracking the bricks. Not all hole saws are created equal. You will want one designed to go through brick. One example:

You'd think Pumice bricks are inferior to heavy refractory ceramic bricks but the truth is they absorb more heat and are superior in many ways

The standard pumice bricks fell apart in my Quads.
