If you want a gas fireplace with a chimney, first decide whether you need a vented appliance or simply want the look and warmth of a fireplace. The five products below are ventless models, so they do not require a chimney according to their listed features; they are not substitutes for a chimney-vented fireplace where venting is required. The Duluth Forge dual-fuel insert suits buyers who want fuel flexibility, while the EROMMY set is for natural-gas users seeking remote controls. Other picks prioritize propane, realistic logs, or thermostat operation.
| Product | Best For | Fuel | Listed Heat Output |
|---|---|---|---|
| Duluth Forge Dual Fuel Insert | Fuel flexibility and remote operation | Natural gas or propane | 32,000 BTU |
| EROMMY Ventless Log Set | Natural gas with remote settings | Natural gas | 32,000 BTU |
| Duluth Forge Propane Insert | Propane and built-in styling | Propane | 26,000 BTU |
| Duluth Forge Split Oak Log Set | Natural gas and detailed logs | Natural gas | 33,000 BTU |
| Duluth Forge Natural Gas Stove | Thermostat-controlled zone heating | Natural gas | 25,000 BTU |
Duluth Forge Dual Fuel Fireplace Insert
Best for: Buyers who want a ventless insert that can use either natural gas or liquid propane. Its listed 32,000 BTU output is intended to heat spaces up to 1,500 square feet, and its remote has an LCD screen for turning the burner on and off.
The six hand-painted ceramic fiber logs, mesh double doors, and sprayed brick liner give it a traditional insert appearance. Manual flame adjustment provides another control option. It was selected for its two-fuel flexibility and combination of heating and styling features.
Limitation: This is a ventless model, not a chimney-vented fireplace. Avoid it if your project specifically requires exhaust to pass through a chimney.
EROMMY 24-Inch Ventless Fireplace Logs
Best for: Natural-gas users who want remote operation with manual and thermostat modes. The listed 32,000 BTU burner is rated to heat up to 1,100 square feet. The remote also offers temperature settings, a child-lock feature, and Fahrenheit or Celsius display.
Six hand-painted ceramic logs provide a realistic log-set look. An automatic shutoff is listed if no signal is detected for 15 minutes, with a two-hour shutoff behavior described in the product features. This model stands out for its remote controls and natural-gas heating capacity.
Limitation: It is specified for natural gas only. Choose another option if you need a propane appliance or a chimney-vented system.
Duluth Forge 26,000-BTU Propane Insert
Best for: Buyers who use liquid propane and want an insert designed for a recessed or mantel-paired appearance. The listed output is 26,000 BTU, with heating coverage up to 1,350 square feet. Its zero-clearance design is described as suitable for recessing into a wall or pairing with a face mantel.
Five hand-painted ceramic fiber logs and a dual precision-ported burner are intended to create a realistic flame presentation. This product is a useful comparison against the dual-fuel insert for buyers who have already settled on propane and want a built-in look.
Limitation: It uses liquid propane and is ventless. It is not the right choice for a natural-gas connection or a required chimney exhaust.
Duluth Forge 24-Inch Split Oak Log Set
Best for: Natural-gas buyers who prioritize detailed log styling and higher listed heat output. The 33,000 BTU set is rated for spaces up to 1,300 square feet and includes nine ceramic fiber logs molded with bark, split, and charred details.
Its burner system has a glowing ember bed and a single flame row; ember material is included. This set was selected for shoppers comparing realistic log appearance and heat output rather than a freestanding stove or enclosed insert.
Limitation: The listed fuel is natural gas, and the set requires no venting. It does not meet a need for a chimney-vented appliance.
Duluth Forge Natural Gas Stove
Best for: Natural-gas users seeking a freestanding stove-style appliance with thermostat control. Its 25,000 BTU output is listed for heating up to 1,100 square feet. Variable settings automatically cycle the stove on and off to maintain the selected room temperature.
The dual burner creates two rows of flames around five hand-painted ceramic fiber logs, viewed through a large display area. Choose this model if you prefer a stove format and temperature cycling over a fireplace insert or open log-set presentation.
Limitation: This is a natural-gas, ventless stove rather than a chimney-connected fireplace. Its listed fuel does not include propane.
Buying Guide: How to Choose a Gas Fireplace
Do you need a chimney or a ventless appliance?
These five products are described as ventless or as requiring no venting. A chimney-vented gas fireplace is a different category: it directs exhaust outside through an approved vent or chimney system. Confirm the appliance type and installation requirements before buying. Check local rules and the manufacturer’s instructions, and consult a qualified installer if you are unsure whether a ventless unit is permitted for your home.
Which fuel does your home use?
Match the appliance to the available fuel. The Duluth Forge dual-fuel insert lists both natural gas and liquid propane. The EROMMY logs, split oak log set, and stove are listed for natural gas; the 26,000-BTU insert is listed for propane. Do not assume a model can be converted unless its documentation explicitly says so.
How much heat output do you need?
Compare the listed BTU output and coverage area with the room you intend to heat. The products list coverage from 1,100 to 1,500 square feet, but the actual suitability of a unit depends on the home and installation. Consider whether you want zone heating for one area or a different heating solution for the whole home.
Should you choose an insert, log set, or stove?
An insert is suited to a built-in fireplace appearance, while a log set emphasizes visible logs and flames. A freestanding stove provides a separate appliance format. Remote controls and thermostat settings vary by model, so compare the specific controls rather than assuming every product includes them.
