Not for gas starters

11/30/2015 by Barrett

If you have a gas starter in your wood burning fireplace, this product might give you trouble. You need to create gaps through the metal pad so that the gas flames can go through it. I did not do so at first, and the metal pad diffused the gas flames and thus rendered the gas starter useless. Overall, I can see that this product does in fact create very fine ashes, it is not worth the hassle of using it in my fireplace that has a gas starter.More > < Less


So sorry!

Seems to be an excellent idea. However, I had to return it because we do not have a grate in our woodstove.

Definitely burns all the wood with little left over - our fires are more efficient! It does require to be cleaned more frequently than burningurning wood without the Firemizer.
I will be recommending it to friends and family.

Not for me.

Sorry, but this didn’t work well for me. Very messy and very hard to handle too.


Christmas gift

Gave this a Christmas gift to my parents who have a wood burning fireplace. It seemed like a good idea in concept but it needed up being difficult to shake the ash out and then it broke in half after 3 uses. I will be checking about a replacement and see if I just got defective piece.More > < Less

About Firemizer

Fires Burn Better

If you heat your home with a wood burning stove or insert—or even if you just enjoy your fireplace or fire pit from time to time—a Firemizer should be on the bottom of it. Your wood will last up to 33% percent longer.

Firemizer is a reusable mat made of stainless steel mesh. It spreads heat more evenly and burns even the smallest pieces of fuel down to ash that you just brush away between fires. The amount of fuel you use—and the amount of creosote in your chimney—are reduced, and burn time is increased by up to one-third.

Wherever you use the Firemizer, trim it to fit using a standard wire cutter. Wear gloves when you handle it, though, to avoid steel splinters. Then enjoy a more efficiently burning fire that won’t burn through your heating budget.
