The GOWE 28-inch fireplace insert is the closest match to a specifically 28-inch search, while Duluth Forge offers gas inserts with stated 32,000-BTU output and dual-fuel operation. The right choice depends on whether you need a complete insert, want thermostat or remote control, or are shopping for gas logs to fit an existing fireplace. The log sets below are alternatives, not complete inserts; confirm dimensions, fuel requirements, and installation rules before choosing any model.
| Product | Best suited for | Key distinction |
|---|---|---|
| GOWE 28-inch Fireplace Insert | Buyers prioritizing a stated 28-inch size | Infinity log effect and cycling accent colors |
| Duluth Forge FDI32R | Buyers wanting remote control and fuel choice | 32,000 BTU; natural gas or propane |
| Duluth Forge FDF400T-ZC | Buyers wanting thermostat control | Automatic temperature cycling |
| Duluth Forge DLS-30R-2 log set | Owners of an existing fireplace | 30-inch ventless log set, not an insert |
| Duluth Forge DLS-N24R-1 log set | Natural-gas log-set shoppers | 24-inch set with stated 33,000-BTU output |
GOWE 28-Inch Fireplace Insert
Best for: Shoppers whose first filter is a listed 28-inch size. Among these options, this is the only product whose name explicitly states a 28-inch measurement.
The listed features describe an Infinity Log effect intended to create a realistic log appearance. The unit also cycles through accent-color options, allowing buyers to change the visual effect. Those details may suit someone who values decorative lighting and a log-style display alongside the stated insert format.
Why it was selected: Its listed width makes it the closest direct match to a 28-inch fireplace insert search. The product information provided does not specify fuel type, BTU output, heating coverage, or whether it is gas-powered. Buyers should verify those details with the seller before treating it as a gas-heating option.
Limitation: The available feature description is brief and does not confirm gas operation or heating performance. Avoid choosing it based on size alone if you specifically require a gas insert.
Duluth Forge FDI32R Dual-Fuel Insert
Best for: Buyers who want a gas insert with remote operation and the option to use natural gas or liquid propane. The listed output is 32,000 BTU, and the product description says it can heat up to 1,500 square feet.
The FDI32R is described as a ventless, dual-fuel insert. Its remote has an LCD screen and can turn the burner on and off; the feature list says a standing pilot allows remote flame operation. Manual flame adjustment is also listed. The design includes nine hand-painted ceramic-fiber faux logs and a mesh screen.
Why it was selected: It combines the insert format with fuel flexibility, a remote, and a stated heating output. It is a better fit than a log set for someone shopping for a fireplace insert rather than burner components for an existing fireplace.
Limitation: The listing describes this as ventless, so it is not the right choice for a buyer who specifically requires a vented appliance. Confirm local requirements and installation instructions before purchase.
Duluth Forge FDF400T-ZC Thermostat Insert
Best for: Buyers who prefer a thermostat to maintain a desired room temperature automatically. This model is also listed as dual-fuel, with natural gas or liquid propane as fuel choices.
The product description gives a 32,000-BTU rating and says the vent-free heater can heat up to 1,500 square feet. Its thermostat cycles the unit on and off to maintain the selected temperature. Appearance details include six hand-painted ceramic-fiber faux logs, mesh double doors, and a sprayed brick liner.
Why it was selected: Its thermostat control is a meaningful alternative to the FDI32R’s remote-based operation. Choose this model if automatic temperature cycling matters more than the other insert’s listed LCD remote and nine-log design.
Limitation: This is also described as ventless. The listed features do not establish that it fits a particular 28-inch opening, so measure the fireplace and verify the appliance’s full installation dimensions before buying.
Duluth Forge 30-Inch Stacked Oak Log Set
Best for: Owners of an existing fireplace who want a ventless gas log set with remote operation. This is not a complete fireplace insert, so it is best considered when the fireplace and installation setup are already suitable for a log set.
The 30-inch set is described as dual-fuel, supporting natural gas or liquid propane. Its vent-free burner is rated at 33,000 BTU. The package features nine hand-painted stacked red oak logs, an iron grate, a U-burner chassis, and a bag of embers. A remote turns the burner on and off, while manual flame adjustment is also listed.
Why it was selected: It provides a log-set option for shoppers comparing ways to update an existing fireplace rather than installing a complete insert. Its 30-inch size is not the same as a 28-inch insert dimension, so opening fit must be checked independently.
Limitation: This product is a log set, not an insert. Do not choose it if you need a self-contained insert or have not confirmed that your fireplace can accept this type of burner.
Duluth Forge 24-Inch Natural-Gas Log Set
Best for: Buyers seeking a natural-gas log set for a compatible existing fireplace. The listed 24-inch size may be relevant when a 30-inch set is too large, but it is not a 28-inch insert.
The product description states 33,000 BTU and heating coverage of up to 1,300 square feet. It is described as ventless and natural-gas fueled. The set includes nine ceramic-fiber split-oak logs with hand-painted bark, split, and charred details. Its burner system has a glowing ember bed and a single flame row, with ember material included.
Why it was selected: It offers a different size and a natural-gas-only configuration compared with the 30-inch dual-fuel set. Choose it if your fireplace measurements and fuel supply align with the listed specifications.
Limitation: This is a log set rather than an insert, and the listing identifies natural gas rather than dual-fuel operation. Confirm the required fireplace dimensions and installation conditions before buying.
Buying Guide: How to Choose a 28-Inch Gas Fireplace Insert
Does “28-inch” refer to the opening or the appliance?
Check what the measurement describes before comparing products. A product name may state a nominal width, while the fireplace opening and the appliance’s full installation dimensions are separate measurements. Record the opening’s width, height, and depth, then compare them with the manufacturer’s dimensional and clearance information. The product details provided here do not give full dimensions for every model, so do not assume that a 28-inch opening will accept an item labeled 28 inches.
Do you need an insert or a gas log set?
A complete insert and a log set serve different buying needs. The Duluth Forge FDI32R and FDF400T-ZC are listed as fireplace inserts. The DLS-30R-2 and DLS-N24R-1 are gas log sets intended for an existing fireplace. A log set does not become a complete insert just because it has a burner, logs, and controls. Confirm what components are included and whether your fireplace is suitable for the product type.
Which fuel type should you choose?
Fuel compatibility can narrow the choice quickly. Both Duluth Forge inserts and the 30-inch DLS-30R-2 are described as dual-fuel products for natural gas or liquid propane. The 24-inch DLS-N24R-1 is listed for natural gas. The GOWE feature information supplied here does not state its fuel type, so check the full product specifications if gas operation is essential.
Remote or thermostat control?
Choose a control based on how you want to operate the fireplace. The FDI32R lists an LCD-screen remote, on/off operation, and manual flame adjustment. The FDF400T-ZC lists thermostat control that cycles the unit on and off to maintain a desired room temperature. The 30-inch log set also lists a remote and manual flame adjustment. Do not assume that controls offer functions beyond those stated in the product details.
How much heat output do you need?
Use the stated BTU rating and coverage as comparison points, not guarantees for every home. The two Duluth Forge inserts list 32,000 BTU and coverage up to 1,500 square feet. The 30-inch and 24-inch log sets list 33,000 BTU; the 24-inch set gives coverage up to 1,300 square feet, while the 30-inch listing does not state a coverage figure. Actual heating needs depend on the room and installation conditions.
What should you check before installing a ventless model?
Several products in this selection are described as ventless or vent-free. Before purchasing, review the complete manufacturer instructions and check applicable local rules and installation requirements. Verify clearances, room suitability, fuel supply, and any required professional installation details. Do not assume that the absence of an outside duct or chimney means an appliance is suitable for every room or home.
