from 4072 reviewsI 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.

Great service and great product

Product is great, free shipping was good, and unpacking and installing it was easy. Customer support was great too, both with the sales and shipping carrier. After much research…the Modern Flames Redstone is the one.

A+ = both the sale, the shipping process, and the product

I purchased burner and fire box. I emailed and spoke with Jim . He helped me from start to finish. Great service
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!

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.

Came as advertised and without any delays. Arrived quickly. No issues and would buy from flame authority again.

I wanted to make sure of the size and features of this oven. I called Flame Authority and Mary answered the call. She gave me all the details and I was really amazed coz she really knows what she is selling. Expert with sales and communication. Thumbs Up!

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.!

Nice , polite and helpful, when you would call with questions.Fireplace looks nice and throws a decent amount of heat , just a bit of a delay in delivery. Ended up getting it End of January, right before guests arrived. But still only took 3 weeks to get. Thank you Flame Authority !!!

I didn't expect to have this fireplace earlier than the lead time they promised. It looks stunning in my living room and now we are prepared for the upcoming winter season! I am happy with all the updates! Customer service representatives keep on updating me with the process of my order until delivery they are checking it for you! 10 stars for Flame Authority!

Simply beautifully designed. Very efficient. Looks gorgeous in our mid century modern home in a corner space. Will save us $$$ on electric heat bills and is easy to clean with fireplace glass cleaner.

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.

Thank you for a very smooth transaction. the remote is very useful. It is very easy to install

Honestly exceeded our expectations. It cuts down our heating costs noticeably and easily keeps up with our cold winters. We went with it because it burns cleanly and produces very little ash, and we were able to get it set up without any major remodeling. The fit and finish are excellent. I would absolutely recommend the Model 21NC to anyone needing a reliable, compact stove for zone heating or smaller homes.
We installed the Buck Stove Model 21NC earlier this heating season, and it has honestly exceeded our expectations. It lights up quickly and holds a steady burn and easily keeps up with our cold winters. You can tell this stove includes a blower that helps move heat across the room. It feels sturdy and dependable, and I expect it to last for many seasons to come.
On top of all that, it burns cleanly and produces very little ash. The heat distribution is great, and the atmosphere it adds to our home is such a bonus. Nice performance!
A total game-changer for our home. It heats our 1,200 sq. ft. space easily and efficiently, even during some of the coldest nights this winter. What surprised me most is how little ash it produces. It burns cleanly, and I only need to do a quick cleanout every few days, which is a huge upgrade from our old stove. The stove also adds a warm, cozy touch to our space. Between the look of the flame and the even heat, it’s become the center of our home life on winter evenings.
The build quality is excellent. Everything about it feels solid and well-crafted. The door seals tightly, and the materials are definitely made to last. All in all, this stove has exceeded expectations. I would not hesitate to buy another one if I needed heat in a second space.
I absolutely love our Buck 21NC! It is our first wood stove, and it was important to find something that was efficient but also beginner-friendly. This unit totally fits the bill. It lights up easily and keeps a consistent temperature with very little fuss. We use it to heat the main level of our home. Around 1,300 sq. ft. and it handles the space with no trouble at all. It really shines on cold nights, keeping everything warm without needing to run our electric baseboards. Definitely recommend for smaller to mid-size homes.
