For a fireplace without a chimney, choose a ventless gas model if you want real gas flames and fuel flexibility; choose an electric model if you prefer adjustable flame effects and app-based controls. The Duluth Forge dual-fuel insert is best for insert-style heating, while the Touchstone electric fireplace offers three-sided installation options and smart controls. The right choice also depends on local rules, room conditions, installation needs, and whether you have access to natural gas or propane.
| Product | Type | Best suited for |
|---|---|---|
| Duluth Forge FDI32R | Ventless gas insert | Dual-fuel heating and remote operation |
| Duluth Forge QSN250T | Ventless natural gas stove | Thermostat-controlled natural gas heat |
| Duluth Forge FDSR25 | Ventless dual-fuel stove | Remote temperature control and fuel choice |

| Bluegrass Living BTSD23RT | Ventless dual-fuel stove | Three-sided flame viewing and dual-fuel operation |
Duluth Forge FDI32R Dual-Fuel Insert
Best for: Buyers who want a ventless gas insert with a choice of natural gas or liquid propane. This model is rated at 32,000 BTU and is listed to heat up to 1,500 square feet. Its insert format may suit someone planning a fireplace-style installation rather than a freestanding stove.
The included remote has an LCD screen and operates the burner on or off. The product also has manual flame adjustment, nine hand-painted ceramic fiber logs, and a mesh screen. Its listed vent-free design does not require an outside duct or chimney, but installation and permitted use still depend on local requirements and the room.
Consideration: This is a gas-burning appliance, so it requires an eligible fuel supply and attention to the manufacturer’s installation and operating instructions. Choose another type if you do not want to use gas.
Duluth Forge QSN250T Natural Gas Stove
Best for: Households that use natural gas and want thermostat-controlled heat in a freestanding stove format. The listed output is 25,000 BTU, with coverage stated at up to 1,100 square feet. Variable heat settings automatically cycle the stove on and off to maintain the selected room temperature.
A dual burner creates two rows of flames around five hand-painted ceramic fiber logs. The large viewing area emphasizes the flame display while the thermostat control makes this model distinct from products that rely mainly on manual adjustment or a basic on-off remote.
Consideration: This stove operates on natural gas only. It is not the right pick for buyers who need propane compatibility or want an electric fireplace without a gas connection.
Duluth Forge FDSR25 Dual-Fuel Stove
Best for: Buyers who want a freestanding gas stove with remote temperature control and a choice of natural gas or liquid propane. The listed 26,000-BTU blue-flame heater is specified for areas up to 1,200 square feet. The thermostat remote lets users select a desired temperature and control the log set.
The unit includes six hand-painted ceramic fiber logs. Its dual-fuel feature makes it more flexible than the natural-gas-only QSN250T, while its stove format differs from the FDI32R insert. The listed remote system uses four AA and two AAA batteries, which are included according to the product details.
Consideration: Remote operation depends on batteries. Choose an electric fireplace instead if you want to avoid a gas appliance, or verify that the intended fuel and installation are suitable before buying.
Touchstone Sideline Infinity Pro Electric Fireplace
Best for: Buyers seeking an electric fireplace with smart controls and several built-in viewing configurations. This 60-inch model supports three-sided, left-visible, right-visible, or front-only installation. It can be plugged in or hardwired, according to the listed features.
Users can adjust flame color, brightness, speed, and heat using the touchscreen, remote, or smartphone app. The product includes six flame colors, 13-color downlighting, a 1,500-watt heater, and adjustable crackle sound. Its electric design avoids the need to choose between natural gas and propane, making it a useful contrast to the gas stoves and insert in this comparison.
Consideration: The listing describes installation choices, but the appropriate setup depends on the intended location and electrical requirements. Choose a gas model if real gas flames and fuel-based heating are priorities.
Bluegrass Living BTSD23RT Panorama Stove
Best for: Buyers who want a vent-free gas stove with three-sided flame viewing and dual-fuel operation. Its listed 23,000-BTU output is specified for areas up to 1,100 square feet. The fuel system can use either natural gas or liquid propane, subject to the installation instructions.
The U-burner chassis and hand-painted ceramic fiber logs create a two-row flame presentation visible from multiple angles. A thermostat remote with an LCD screen lets users adjust temperature, mode, and flame; the display also shows room temperature and burner status.
Consideration: This is still a gas-burning appliance, despite its vent-free design. Buyers who want a non-gas option or who cannot use a ventless appliance in their location should compare electric models instead.
Buying Guide: Ventless Gas Fireplace vs. Electric
How do gas and electric fireplaces differ?
A ventless gas fireplace burns natural gas or propane, depending on the model, to produce heat and a real gas flame. The products here include gas inserts and freestanding stoves. An electric fireplace uses electricity and provides an artificial flame display; the Touchstone model also lists a 1,500-watt heater. Neither category should be assumed suitable for every home or room without checking its installation requirements.
Ventless means the appliance does not use an outside duct or chimney as described for the product. It does not mean the unit has no safety or room-use requirements. Follow the product manual, local building and fire rules, and any restrictions that apply where you live. Consult a qualified professional if you are unsure about installation or fuel connections.
Which fuel or power source do you have?
Fuel availability narrows the choices. The Duluth Forge FDI32R, FDSR25, and Bluegrass Living BTSD23RT are listed as dual-fuel models for natural gas or liquid propane. The QSN250T is listed for natural gas only. The Touchstone fireplace is electric, so it avoids a gas fuel connection but requires a suitable electrical setup; its listing offers plug-in or hardwire installation.
Do not infer that a dual-fuel product can switch fuels without following its instructions. Confirm the configuration and installation requirements before purchase. If you rent, live in a multifamily building, or have restrictions on fuel-burning appliances, check with the property owner or relevant local authority first.
How much heating capacity do you need?
Compare the listed BTU output and coverage area with the space you want to heat. Among these gas models, the FDI32R lists 32,000 BTU and up to 1,500 square feet; the FDSR25 lists 26,000 BTU and up to 1,200 square feet; the QSN250T lists 25,000 BTU and up to 1,100 square feet; and the Bluegrass Living stove lists 23,000 BTU and up to 1,100 square feet. These are product-listed figures, not a guarantee of performance in every home.
Room layout, insulation, ceiling height, climate, and whether the fireplace is intended as primary or supplemental heat can affect what capacity is appropriate. The supplied product details do not give an equivalent coverage-area figure for the Touchstone electric model, so compare its heater specifications with your room and electrical needs rather than assuming it matches a gas model’s listed area.
What controls and viewing style matter?
Choose the control scheme that fits how you use the room. The QSN250T uses thermostat control to cycle heat toward a selected temperature. The FDSR25 and Bluegrass Living stove include thermostat remotes, while the FDI32R remote operates the burner and also has manual flame adjustment. The Touchstone offers control through a touchscreen, remote, or smartphone app, plus several flame and downlighting settings.
For appearance, consider the room’s layout. The Touchstone has four installation configurations, including three-sided and front-only views. The Bluegrass Living stove also has a three-sided view, while the other gas products list logs and flame features without the same multi-angle description. Compare the intended viewing position with the space available for installation.
What safety and installation checks should you make?
Read the full manufacturer instructions before choosing a ventless gas appliance. Confirm that the specific model is permitted in your jurisdiction and appropriate for the room. Follow required clearances and ventilation guidance, and use qualified installation help when needed. Gas-burning appliances can affect indoor air and add combustion byproducts and moisture to a space, so do not treat “vent-free” as a substitute for checking room conditions and safety guidance.
For either type, verify dimensions, placement, electrical or fuel connections, and the installation method before ordering. A product’s listed heating area or installation options do not establish that it will fit every room. For electric units, check the electrical requirements and whether plug-in or hardwire setup is appropriate for the intended location.
Frequently Asked Questions
Is a ventless gas fireplace better than an electric fireplace?
