Fire Lasts Longer

10/2/2017 by CJ Live

This is a repeat order because it does fall apart over time. Because I live in the city and buy wood from the grocery which is the expensive way, I can use this and one fire bundle instead of two for an evening. This pays for itself. Must have rubber gloves to clean up post fire. An excellent idea and product.More > < Less

I ordered 2 of these for Christmas presents. Well actually 3 because my dog ate part of one when UPS delivered it so I had to reorder 1. Added bonus - on top of it being an amazing product it isn't harmful to your pets digestive system. Back on topic.... I ordered 1 for our house and 1 for my parents house. In both cases we always had a difficult time getting a fire started and keeping it going due to how the fire place draws and the height of the fire grate. Once we installed this baby all I can say is PROBLEM SOLVED. Fires start easily and stay burning with less wood and less care. It truly takes enjoying our fireplace to the highest level. I have recommended this to serveral friends and family.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.
