I love this Burner

I am impressed with the quality of this Ethanol Burner as well as the heat that it gives and the fire i see. Ignis has a very good quality product looks like all the way. I was also surprised to see in description that it burns for 8 hours when it actually gave me 9.5, maybe i went over the Max line but i love it. If you want to convert your Dirty wood burning fireplace then this is the solution.

Almost Perfect!

The reason why i rate EB6200 at four stars is because first one was damaged due to shipping but second one was sent out minutes after i called it in. Other than that it looks very hot on my floating wall and it works better then what i have seen on youtube. It's worth every penny i paid and that is the longest unit there is on the market, well at least i didn't find any other once.

This Burner is something that i have not seen before in my entire life. Now since we have one i know exactly that it was it. I like the way it is made and the fact that its very heavy i can tell its a good quality labor. I lid it on my Wife's B-day party and it was the only thing our friends just kept talking about, i even felt like it was a fireplace party in some way. Any way i like it my wife loves it and my quests just go crazy over this technology. Thanks to Ignis (from my wife).

Fireplace Geek

I always had a Real Fireplace in my vacation house up until This day. My contractor has installed this fireplace last month and i enjoy every second of it. I never thought the technology would move forward this much until like i said This day. I really recommend ether this or any other ethanol fireplaces , they are beautiful.
