I Bought & Tested the Best-Selling Firebacks for Fireplace. Here's Why Kilnora is #1:
Written by Sarah Jennings
That crack was my wake-up call, but my first fix made things worse. I ordered a thin, bargain steel plate online and slid it against the back wall. Within two weeks the corners had bowed, it tipped over when a log rolled into it, and soot was still creeping up the brick around its edges.
Next I borrowed a vintage cast-iron plate from a neighbor. It protected the brick, but it weighed about as much as a toddler, and every cleaning session turned into a back-straining wrestling match. Weeks of reading spec sheets and forum threads left me with contradictory claims and no real numbers.
Then a reader who'd survived the same ordeal pointed me toward Kilnora, a brand I'd never heard of. I didn't trust one recommendation, so I gathered four better-known rivals and built a proper test. After seven years and 42+ home heating and hearth products, I wanted data, not hype.
Here's what I found.
My Test Results
I ran all five firebacks for fireplace through six weeks of real burns in my own brick firebox, using seasoned oak and the same stacking pattern every time. Each plate got at least six burns of three to four hours, mostly on weeknight evenings plus a few long weekend fires. I logged room temperature on a thermometer ten feet from the hearth and checked rear-brick surface heat with an infrared gun, with readings held to within a few degrees of each other.
I scored every plate on four criteria: Heat Reflection, Material Durability, Installation Stability, and Size Versatility. Heat came from baseline comparisons against a burn with no plate at all. Durability meant checking for warping, flaking, and rust after repeated hard burns. For stability, I deliberately nudged logs against each base, and for size, I test-fitted each plate in my firebox and in two friends' fireplaces.
The first thing I noticed was warmth. On a baseline burn with no fireback, my thermometer ten feet from the hearth gained roughly 8°F in ninety minutes. With our top pick in place, the same fuel load produced about 14°F, a gain of around 6°F over baseline and 2-3°F ahead of the next-best plate. Rear-brick readings also ran noticeably cooler, meaning the plate absorbed the thermal punch instead of my masonry.
Secondary results impressed me just as much. The soot that normally greets me on the back wall wiped off the plate with a dry cloth in under two minutes, and the fire itself looked steadier, likely thanks to the airflow gap beneath it. After six hard burns, the finish showed no flaking, no warping, and no wobble, even when I deliberately rolled a log against the base.
The weaknesses were minimal. The only real frustration was availability: it was sold out the first time I tried to order, and I waited two weeks, which pushed my test schedule back. In use, I found nothing to criticize beyond making sure your opening is close to standard size.
The Results:
Kilnora earned the #1 spot by outscoring every rival on heat, durability, stability, and fit.
Value
Since adding this plate, I've stopped hauling in extra armloads of wood, stopped scrubbing soot off my back wall every month, and stopped dreading a second masonry repair. The value shows up in time reclaimed and hassle removed, not in a line on a receipt. Compared with heavier iron or ornate designs, you get stainless performance that's easier to live with every single week.
Doing nothing is the expensive option. An unprotected firebox keeps absorbing thermal stress, soot keeps building, and heat keeps escaping up the flue. Cheap thin plates often just postpone the problem, warping within a season and leaving you shopping again. I know, because I bought one.
On durability, I judge by what I can verify. After six weeks of hard use, I saw no warping, no flaking, and no wobble, and I expect this build to outlast the bargain plates by years. Check the seller's warranty terms on the product page, but based on my testing, this is a smart long-term decision for any wood-burning hearth.
How a Fireback Changes Your Evenings by the Fire
These days, lighting the fire no longer comes with a low hum of worry. I stopped checking the back wall every few minutes, and the room warms up evenly enough that my kids drop the coats and settle on the rug. The fire looks cleaner too, and the steel catches the flames in a way that makes the whole hearth feel intentional.
The benefits stretch well beyond my living room. Older homes with aging firebrick, cabin owners heating drafty spaces, and families who simply love a real fire all gain from a plate that protects masonry while pushing warmth outward. If you burn wood regularly, this is one of the quietest upgrades you can make.
Customer Reviews
Our 1890s farmhouse fireplace had already needed one masonry repair, and I was dreading a second. We installed this before last winter and burned roughly sixty fires. Zero new cracks, and the room warms noticeably faster. I only wish I'd found it before the mason's visit.
I use my fireplace for weekend ambiance, and the soot on my white wall used to drive me crazy. Now it wipes off the plate in a couple of minutes. Simple as that.
Bill's shoulder isn't what it used to be, so we worried about wrestling a heavy plate into place. This one went in without tools in about five minutes, and it hasn't budged all season. The den feels cozier, and we feel better knowing the brick is covered.
Frequently Asked Questions
Yes, in my testing it did. A reflective plate sends radiant heat back into the room instead of letting your bricks soak it up. With our top pick in place, my living room climbed roughly 6°F higher after ninety minutes than on a baseline burn with no fireback.
Measure the width and height of your firebox back wall first. For standard residential openings, a plate around 16 by 18 inches is a safe fit, which is why Kilnora suited most hearths I tried it in. Go wider only if your firebox is truly oversized.
Stainless steel is lighter, resists rust, and wipes clean easily. Cast iron is thicker and more massive, but it is harder to reposition and needs regular upkeep. For most homeowners, stainless offers the better balance.
Yes. The best models need no tools: you set the plate on its feet against the back wall and adjust the angle. Kilnora took me under five minutes.
Always let the firebox cool completely first and wear gloves.
Firebacks are designed mainly for wood-burning fireplaces. If you burn gas logs or use a ventless unit, check the manufacturer guidance before installing any plate. When in doubt, ask a certified chimney professional.
Wait until it is fully cool, then wipe the face with a dry or slightly damp cloth. Smooth stainless surfaces release soot in a couple of minutes, while textured or ornate patterns take more scrubbing. Regular wiping keeps the plate reflecting at full strength.
Leave a small gap so air can circulate behind and under the fire. Adjustable feet make this easy, letting you fine-tune both the angle and the spacing. Always follow the manufacturer clearance guidance for your specific model.
Demand outpaces supply. I waited two weeks before I could order mine, and readers report that restocks sell out within days. If this model is available when you click through, ordering promptly is the safest move.
Purchase and Delivery Process
Ordering is simple. This fireback is sold exclusively online, which means no retail markups and no hunting through hardware aisles.
The catch is availability. It's frequently out of stock, and I personally waited two weeks before I could place my order because it had sold out.
If you see it available, don't wait. Once I ordered, delivery was quick, and my plate arrived in about a week.
