Touchstone Fireplug 33″ Electric Fireplace Insert

Check Price on Amazon

The Touchstone Fireplug 33″ is designed to fit into existing masonry fireplace openings and convert a traditional hearth into a modern electric heating zone. The unit face measures 35″ W x 27″ H with a recessed portion that fits into smaller openings, which can ease installation in many masonry fireplaces.

Key features include 6 flame colors, 13 ember colors, adjustable flame speeds, and optional Wi‑Fi/Alexa control. The unit emphasizes visual ambiance with painted glass crystals and driftwood-style logs in the ember bed.

For masonry heater projects, this unit is relevant when a homeowner prefers an electric insert instead of rebuilding or relining a wood-burning masonry heater. It provides heat via a 1500W heater, supplemental warmth, and a sealed electric option that avoids combustion concerns inside a modified masonry structure.

Rutland Fire Brick & Mortar Kit

Check Price on Amazon

The Rutland Fire Brick & Mortar Kit is a focused refractory repair kit that includes five fire bricks and two pounds of high-temperature refractory mortar.

This kit is intended for fireplace, wood stove, and fire pit repairs where heat-resistant bricks and mortar are required. The mortar is formulated for service at elevated temperatures, and the included bricks provide replacement material sized for small repairs or patching a damaged firebox area.

Use cases in masonry heater work include patching flue linings, rebuilding small sections of a combustion chamber, or creating sacrificial lining panels where insulating and heat retention materials are needed. This kit supports maintaining thermal integrity in areas exposed to high heat.

MARSBASE 11PCS Concrete Hole Saw Kit

Check Price on Amazon

The MARSBASE Masonry Hole Saw Kit contains five hole saw sizes (30mm–100mm) plus SDS Plus and SDS Max shanks and multiple pilot bits. The saws use tungsten carbide teeth and a three-blade design for chip clearing and faster cutting.

This kit is useful when creating clean circular penetrations through concrete, brick, or stone for flue pass-throughs, venting, sensor probes, or mounting glands. The inclusion of both SDS Plus and SDS Max shanks increases compatibility with different rotary hammer drills used in masonry work.

When planning a masonry heater installation that requires routed openings—such as ducts or thermocouple ports—these hole saws provide larger diameter capability not covered by standard twist drill bits. Proper mounting and pilot drilling are recommended for safe, accurate cuts.

Dianrui Concrete Drill Bit Kit (10PCS)

Check Price on Amazon

The Dianrui 10-piece masonry drill bit set includes sizes from 5/32″ to 1/2″ with carbide-tipped heads and a wide flute design for dust removal. The bits are heat-treated 45# steel bodies with carbide alloy cutter heads for durability.

These bits are appropriate for pre-drilling anchor holes, pilot holes for lag screws, or creating channels for small conduit through brick and concrete. Their flute design helps keep the bit cool and clears debris more efficiently, which can be important in prolonged masonry drilling tasks.

Choose carbide-tipped bits for repetitive drilling into dense masonry; ensure drill mode (hammer vs. rotary) and proper lubrication or intermittent drilling are used to extend tool life when working with hard materials.

RURITKIT 200Pcs Concrete Screws Assortment

Check Price on Amazon

The RURITKIT 200-piece concrete screw assortment includes multiple sizes of hex-head concrete screws, four masonry drill bits, and two hex sockets. Screws range from 3/16″ to 1/4″ diameters in varied lengths to accommodate different thicknesses of masonry and fixtures.

These self-tapping screws are made from carbon steel with heat treatment and a rust-resistant coating. The kit is intended for anchoring plates, brackets, or mounting hardware to concrete, block, brick, and stucco surfaces—common tasks in masonry heater mounting or accessory installation.

Use the included drill bits to pre-drill accurate holes, then drive the concrete screws to secure attachments like steel straps, mounting flanges, or insulation anchors while maintaining mechanical fastening integrity in masonry substrates.

Buying Guide: Choosing Components For Masonry Heater Projects

This buying guide outlines key factors to consider when selecting materials and tools for masonry heater construction, repair, or retrofitting.

Material Compatibility And Heat Rating

Select refractory bricks and mortars rated for the maximum temperatures expected in the heater’s combustion chamber. Fire bricks and refractory mortar should specify heat ratings and be formulated for repeated thermal cycling without cracking.

Fasteners And Anchoring

Anchors and screws must be sized for substrate thickness and load. Choose concrete screws or masonry anchors with corrosion-resistant coatings for long-term installations. Consider length so threads engage a minimum embedment depth as recommended for the anchor type.

Drill Bits And Cutting Tools

Carbide-tipped drill bits are preferred for durability in concrete and brick. For larger diameter penetrations, use dedicated hole saws or core bits with appropriate shanks (SDS Plus/Max) and pilot bits. Match the tool to your rotary hammer’s horsepower and chisel capability.

Tool Shank And Drill Compatibility

Verify the shank type of hole saws and bits (round, hex, SDS) is compatible with your drill or rotary hammer. Adapters exist, but direct compatibility reduces slippage and increases cutting accuracy.

Thermal Expansion And Jointing

Account for thermal expansion between different materials (brick, metal inserts, concrete). Use mortar or flexible sealants rated for high temperature where components meet. Provide small gaps where required and avoid rigid constraints that can cause cracking.

Ventilation And Flue Considerations

Masonry heaters rely on designed flue paths and mass to capture and release heat. Any penetrations for vents, sensors, or electric inserts must preserve flue integrity and maintain proper clearances to combustibles per local codes.

Local Codes And Professional Consultation

Check local building codes and manufacturer instructions before modifying a masonry heater or fireplace. For structural or combustion-related work, consider consulting a licensed mason or HVAC professional to ensure safety and compliance.

Durability And Replacement Parts

Select kits and components with widely available replacement parts (extra bricks, mortar, bits). For repeat maintenance or future adjustments, having consistent sizes and types simplifies repairs.

Comparison Perspectives

• Refractory Kits vs. Custom Brickwork: Small kits are good for patching, while full rebuilds require bulk materials and professional layout.
• Electric Insert vs. Wood-Burning Rebuild: Electric inserts offer ease and zero-combustion operation; rebuilding a wood-burning masonry heater retains thermal mass performance but requires more complex construction.
• DIY Tools vs. Professional Tools: Homeowner-grade drill bits and hole saws are suitable for occasional use; heavy-duty SDS bits and diamond core bits are warranted for frequent or thick masonry work.

When assembling parts for a masonry heater project, prioritize safety, material heat ratings, and proper anchoring. Combine quality refractory materials with suitable cutting tools and fasteners to achieve durable, compliant installations.
