The right hearth product depends on whether you need a floor-protecting pad, replacement firebrick, or a stove-specific internal baffle. The Plexon stove board is best for buyers seeking a large steel protective surface; the Comfortbilt pad offers a smaller flatwall hearth option; and the firebricks suit repairs inside a stove or fireplace. The two 88138 replacement boards are for owners of listed US Stove, Ashley Hearth, or Vogelzang models who need a compatible baffle board—not a floor hearth.

Plexon 52 x 36 Steel Stove Board
Best for: Buyers who need a broad protective surface beneath or around a heater. This steel board measures 52 by 36 inches and is described as protection against heat, hot coals, ashes, and soot. Its listed applications include wood and pellet stoves, as well as kerosene, gas, and electric heaters.
The product is also described as having a scratch-resistant finish intended to maintain its appearance. Choose this board if its dimensions and material suit your installation and you want a single large surface rather than a smaller pad.
Limitation: The listing does not provide a stated R-value or detailed clearance guidance. Confirm that the board meets the appliance manufacturer’s hearth requirements and local building rules before installation.
Comfortbilt 36 x 36 Flatwall Hearth Pad
Best for: Buyers looking for a square, flatwall hearth pad for a wood or pellet stove. The listed size is 36 by 36 inches, and the color is Black Copper. The product information gives two R-value figures, 2.24 or 1.592, so buyers should check the listing or product documentation to determine which figure applies to their configuration.
Compared with the larger Plexon board, this pad has a smaller stated footprint. Choose it if a 36-inch-square pad fits your planned layout and its documented thermal rating meets the stove’s requirements.
Limitation: The supplied product details do not clarify why two R-values are listed or specify additional dimensions. Verify the applicable R-value and required hearth coverage before purchasing.
Six Wood Stove Fire Bricks
Best for: Buyers repairing a stove or fireplace that uses firebricks measuring 9 by 4.5 by 1.25 inches. The six-piece set is described as made from mullite and intended for high-temperature applications. Its stated uses include wood stoves, fireplaces, and other heating applications.
The listing describes the bricks as insulating and says they can help retain heat. These are masonry-style firebricks, not a freestanding floor hearth pad. Choose them when you need replacement bricks and the listed size matches the appliance’s specifications.
Limitation: The listing does not identify specific stove models or confirm a universal fit. Check the required brick dimensions and layout in your owner’s manual before ordering.
Lynn Manufacturing 2802A Replacement Baffle
Best for: Owners of specifically listed US Stove, Ashley Hearth, Breckwell, or Vogelzang models who need a replacement for US Stove part 88138. The board measures 22-5/8 by 14 by 1/2 inches. Listed models include several Country Hearth 2500 and Ashley Hearth 2520E versions, the Breckwell SW2.5, and several Vogelzang VG2520 versions.
Choose this product when the model and replacement part match. It is an internal refractory insulation or baffle component, not a floor-protection hearth board.
Limitation: The listing warns that some 2500 stoves use part 88146 instead. Check the owner’s manual and existing part number before ordering; the listed fit should not be treated as universal.
Pellethead 88138 Ceramic Fiber Board
Best for: Owners of listed Ashley, US Stove, or Vogelzang heaters who need a ceramic fiber board identified as 88138 or 2802A. Listed models include Ashley AW2520E-P and AW2520E-BP; US Stove US2500E-P, US2500E-BP, US2500E-L, US2500E-BL, and 2500 Country Hearth; and multiple Vogelzang VG2520 versions.
This is another model-specific internal replacement, so it is better suited to a repair than to creating a protected floor area. Compare the model number and part reference with the appliance documentation before choosing it.
Limitation: The provided feature list does not state the board’s dimensions. Confirm the required size and exact part number with the manual or appliance parts information before purchase.
Buying Guide: How to Choose a Hearth Product
Do you need floor protection or an internal stove part?
Start by identifying where the product will be installed. A hearth pad or stove board goes under or around a heater to protect the floor from heat and debris. Firebricks line a firebox or heating chamber. A baffle board is an internal component specific to certain stove models. These product types are not interchangeable, even when their names include “hearth” or “stove.”
If you are replacing a worn component inside the appliance, use the owner’s manual to identify its name and part number. If you are setting up floor protection, consult the stove manual for the required hearth dimensions and thermal protection.
How should you compare hearth pads and stove boards?
Compare the protective surface’s measurements with the footprint and required coverage stated by the heater manufacturer. The Plexon board is listed at 52 by 36 inches; the Comfortbilt pad is 36 by 36 inches. Those dimensions help with planning, but they do not establish that either product meets the requirements for every stove.
Thermal performance also matters. The Comfortbilt listing includes R-value figures, while the Plexon feature list does not state one. Do not assume that a larger board or a steel surface provides a particular level of insulation. Confirm the product’s documented rating and construction requirements for your appliance.
What should you check before buying replacement firebricks?
Measure the existing bricks and compare their dimensions with the replacement set. The six-piece set in this guide is listed as 9 by 4.5 by 1.25 inches. Also check how many bricks the appliance requires and whether its manual specifies a particular material or arrangement. A close-looking size is not proof of a correct fit.
Firebricks are distinct from a floor hearth pad. Their listed role is inside a stove or fireplace, where heat-resistant lining may be required. Follow the appliance instructions for replacement and placement.
How can you confirm a baffle board will fit?
Match the complete model number and the replacement part number, not just the brand. The Lynn 2802A listing identifies compatibility with particular US Stove, Ashley Hearth, Breckwell, and Vogelzang models, and notes that some US Stove 2500 units may use 88146 instead of 88138. The Pellethead listing names a separate set of model variations and does not provide dimensions in the supplied features.
Before ordering, check the manual, the old component’s marking, and the appliance’s model plate. If those details disagree or the model is not listed, seek confirmation from the manufacturer or an appliance parts specialist.
What information should you verify before installation?
- Confirm the heater’s exact make, model, and required protective coverage.
- Check product dimensions and, where required, its documented thermal rating.
- Use only replacement firebricks or baffle boards that match the appliance specifications.
- Follow the stove manual and applicable local installation requirements.
- Do not treat a general-purpose heater board as automatically approved for every installation.
Frequently Asked Questions
Is a stove board the same as a hearth pad?
Both can provide a protective surface for a heater, but their materials, dimensions, and thermal ratings can differ. Compare the product documentation with the requirements in the heater manual rather than assuming the terms indicate identical performance.
Can I use firebricks as a floor hearth?
The firebricks listed here are described for use in wood stoves, fireplaces, and other heating applications. They are not presented as a complete floor-protection hearth pad. Use a floor-protection product that meets the appliance’s stated installation requirements.
Are the two 88138 replacement boards interchangeable?
Both listings refer to 88138 or 2802A applications, but their stated model details differ. Compare the exact appliance model and part number with each listing and the owner’s manual before selecting a replacement.
Does the Lynn 2802A fit every US Stove 2500?
No universal fit is stated. The product information specifically warns that some 2500 stoves use 88146 instead. Check the manual or existing part number to confirm which board the stove requires.
How do I know what size hearth pad my stove needs?
Use the stove manufacturer’s installation instructions to determine the required coverage and thermal protection. Then compare those requirements with the pad’s listed measurements and documented rating.
