See What Our Clients Say About the Firebox Collection

“Very happy with our firebox. I did plenty of research and selected Bio Flame due to their reviews and UL certification. Do your research, and you will be pleased.”

— Harlow Morgan

“We are extraordinarily pleased with our Bio Flame XL Firebox SS ethanol fireplace. As a “DIY’er”, I found the instructions very clear regarding the installation and use of the fireplace. Our designer had included a fireplace in our master bedroom remodel, yet the cost and logistics of building a vented firebox or running a propane line was not practical. We found the fire to be higher and fuller than any other competitive ethanol fireplace.”

— Amy Morrow

“Highly recommend these guys. They gave us a timely estimate and provided lots of options and info. They installed our firebox within the promised time frame. The installers were super professional. Great company!”

— Lucas Brian
