Great customer service for hard to get refractory brick back

I was able to get a Novus 33 in brick refractory back for my NG Novus fireplace insert. Novus is a high demand item and Flame authority was only supplier without a huge delay from manufacturer. I recommend them for all fireplace needs.

Flame Authority

Beautiful Mantel

The mantel required a little bit of sanding and prep before painting, but was good quality. Flame Authority did an excellent job shipping and it arrived by freight in perfect condition.

The mantel assembled well. I ended up using some construction adhesive to glue the legs on to make it a little more sturdy. I cut pocket holes in the top to attach it to the wall.

Very happy with our purchase!

Blaze Pro Portable Grill

I shopped for a grill for two people. I want it to last for ten years or more. I want it to get really hot for grilling steaks after they have been cooled sous vide. I want it to be useful also for lower temp cooking. This Blaze grill is perfect for me and my wife. Our purchase through Flame Authority was completed with no problems. I am totally satisfied with this grill and highly recommend it for anyone with similar needs.

Great heating stove

I bought the stove couple weeks ago and ended up having a chance running it a few days I am very pleased with the outcome of the amount of heat it gets out also with the amount of hours it burns at least eight hours. I would recommend this for anyone who is looking for hours of heat output. At first when I bought it I didn’t quite know if mine hopes will be for filled but now they are happy with it. I would recommend this to anyone as a trusted tester of it I am very pleased of the outcome it rains.!

Great Customer Service

I believe it was David Novak that helped me. Someone ALWAYS answered the phone and located this burner when I couldn't find it anywhere else. It almost seemed too good to be true. But it wasn't. The burner is now nestled in my new outdoor kitchen and am very pleased.

SimpliFire Built-In 30" Electric Fireplace SF-BI30-EB

Heat output is strong enough

Installed the Redstone 54 into the family room’s old masonry fireplace and it’s made a world of difference. The flame depth is really impressive. It does not look flat like other electric fireplaces I have seen. Plus, the heat output is strong enough to warm up the entire main floor. I love switching between the driftwood and crystal media depending on my mood or decor.

It heats the room surprisingly fast

The Redstone 54 fits perfectly in our basement renovation project. We wanted something clean and modern but still warm and this checks all the boxes. The flames are mesmerizing, and the heater does a great job on chilly nights. I love that I can change the flame color based on the time of day. I tend to go for oranges in the morning and purples or blues in the evening. Plus, it heats the room surprisingly fast.

Easy enough for my kids to use too

I am a home contractor and recently installed this in a client’s farmhouse remodel. They were blown away. The install was smooth, and the final result looks premium. The variety of flame colors is an added bonus they did not know they needed. No fumes, no hassle. Just instant comfort. The touchscreen is responsive, and the remote is easy enough for my kids to use too.

Efficient Heating with a Stunning Visual Display

I’ve been extremely satisfied with the Modern Flames RedStone 54" Electric Fireplace Insert. The installation was straightforward, even for someone like me who isn’t particularly handy.

Easy Installation and Incredible Ambiance

The flames look incredibly real, and the fireplace has become the focal point of the room. We love that it provides the look and feel of a traditional fireplace without the hassle of maintaining one.

A Modern Touch to Our Living Room

After much research, we decided on the Modern Flames RedStone 54" Built-In Electric Fireplace Insert, and it’s been a fantastic choice. The installation was straightforward, and the instructions were clear and easy to follow.
