The best contemporary multi-fuel stove depends on where you plan to use it: the Duluth Forge is a fixed indoor heater that uses natural gas or propane, while the Gas One GS-3400P and GS-3900PB offer portable cooking with butane or propane. The Intcoll stove supports three gas types in a compact outdoor design. BESTFIRE is a powerful two-burner propane option, but it is not multi-fuel. Compare fuel types and intended use before choosing.
| Product | Best suited to | Fuel options listed |
|---|---|---|
| Duluth Forge FDSR25 | Supplemental indoor heating | Natural gas or liquid propane |
| Gas One GS-3400P | Portable cooking and emergency kits | Butane or propane |
| GasOne GS-3900PB | Higher-output portable cooking | Camping fuel or propane |
| Intcoll 3-in-1 stove | Compact outdoor cooking | Propane, butane, or ISO-butane |
| BESTFIRE two-burner stove | High-output outdoor cooking | Propane |
Duluth Forge FDSR25 Dual-Fuel Gas Stove
Best for: Buyers looking for a substantial indoor supplemental heater that can use either natural gas or liquid propane. This is a home-heating appliance, not a portable cooking stove, so it serves a different purpose from the camping products in this guide.
The listed output is 26,000 BTU, and the product information states that its blue-flame heater can heat an area up to 1,200 square feet. A thermostat remote is included for setting the desired temperature and controlling the log set. Its six hand-painted ceramic-fiber logs give the unit a traditional stove appearance.
It is the most appropriate choice here for buyers whose priority is room heating and who have access to one of its stated fuel types. The dual-fuel feature offers a choice between natural gas and propane, rather than the small fuel cartridges used by the portable cooking models.
Limitation: This is a ventless gas heater, and its intended indoor use makes it important to review the manufacturer’s installation and operating instructions and local requirements before purchase. The remote system uses batteries; the listing specifies four AA and two AAA batteries, which are included.
Gas One GS-3400P Dual-Fuel Stove
Best for: Campers and emergency-kit planners who want a portable cooking stove that can run on either butane or propane. The listing says it operates with a single 8-ounce butane cartridge or a 16.4-ounce propane cylinder. Fuel is not included, and a propane converter regulator is included.
The GS-3400P has an adjustable heat dial and piezo-electric ignition, which is designed to light the stove without a separate lighter or matches. That combination makes it a straightforward option for buyers who value a choice of fuel and simple flame adjustment in a compact cooking appliance.
Choose this model if you want a two-fuel portable stove and do not need a stated high-output rating as a primary selection factor. Its listed features focus on portability, ignition, and fuel flexibility rather than multiple burners or a specified cooking output.
Limitation: The listing does not include fuel, so users need to source compatible cartridges or cylinders separately. It is a cooking stove, not a heater for warming an indoor room.
GasOne GS-3900PB 15,000-BTU Stove
Best for: Outdoor cooks who want portable butane-or-propane flexibility along with a stated 15,000-BTU output. The product information lists compatibility with an 8-ounce camping fuel cartridge or a 16.4-ounce, 1-pound propane cylinder. A propane adapter is included, but fuel is not.
Like the GS-3400P, this model has piezo-electric ignition and an adjustable heat dial. Its stated output makes the GS-3900PB a better fit for buyers who want a clearly specified heat rating when comparing portable cooking options. It is also described as suitable for camping, backpacking, and emergency preparedness.
Choose this stove if you want a portable dual-fuel cooking option with the 15,000-BTU figure listed as a selection point. The fuel choices provide flexibility for people who may prefer camping cartridges for one outing and a propane cylinder for another, subject to the product’s instructions.
Limitation: Fuel is sold separately, and the listing describes one burner rather than a multi-burner cooking setup. Do not interpret its BTU rating as a measure of indoor heating capacity.
Intcoll Compact Three-Fuel Camping Stove
Best for: Outdoor users who prioritize a small, lightweight stove and want the listed option of using propane, butane, or ISO-butane. The product description says the stove is about the size of a hand and is designed to be easy to carry.
This is the broadest fuel-choice option among the portable models in this selection based on the supplied product information. The listing also says it adapts to common gas tanks and includes adjustable gas pressure for propane to help maintain flame stability. Those points make it worth considering for buyers who already use different types of fuel containers.
Choose this model when compact size and the three stated fuel types matter more than a listed BTU output or extra cooking features. The available information emphasizes portability and gas compatibility rather than burner count, ignition type, or a specific heat rating.
Limitation: The product details do not specify a BTU output, included ignition system, or exact fuel-container requirements. Check the manufacturer’s instructions to confirm which canisters and connections are suitable before use.
BESTFIRE High-Output Two-Burner Stove
Best for: Campers and backyard cooks who need two burners and high stated output, rather than multiple fuel choices. This model is propane-only according to its supplied product details, so it is an outdoor cooking alternative and not a multi-fuel stove.
The listing specifies two separately controlled burners and a total output of 240,000 BTU. Independent knobs allow users to adjust each flame separately, making the setup suitable for preparing different foods at the same time. A wind shield is included, along with removable legs and two detachable side shelves. The shelves fold for storage, and the listing also mentions a carrying bag and gloves.
Choose this model if cooking capacity and separate burner control are more important than fuel flexibility. Its freestanding design is described as stable on outdoor surfaces such as lawn, dirt, and patios, and the side shelves provide additional preparation space.
Limitation: It uses propane only, so it does not offer the fuel flexibility of the other portable stoves here. Its high output and freestanding format are suited to outdoor cooking, not indoor use.
Buying Guide: How to Choose a Multi-Fuel Stove
Will you use the stove for heating or cooking?
Start with the job the appliance needs to do. The Duluth Forge is a gas heater for supplemental indoor heating. The Gas One, Intcoll, and BESTFIRE products are described as cooking stoves for outdoor use. A stove designed to cook food is not a substitute for a room heater, and an indoor heating appliance is not a portable camp cooker.
For home heating, compare the heater’s stated fuel types, output, coverage information, and installation requirements. For outdoor cooking, focus on fuel-container compatibility, burner arrangement, flame adjustment, portability, and the kind of meals you plan to prepare.
Which fuel options matter most?
“Multi-fuel” does not mean every stove accepts every fuel. In this selection, the GS-3400P is listed for butane and propane; the GS-3900PB is listed for camping fuel and propane; and the Intcoll model names propane, butane, and ISO-butane. The Duluth Forge uses natural gas or liquid propane. BESTFIRE is propane-only.
Before buying, identify the fuel you can reliably obtain and check the exact container size and connection requirements in the product instructions. Similar fuel names do not guarantee that cartridges, cylinders, adapters, or regulators are interchangeable.
Do you need portability or multiple burners?
A compact stove can be easier to pack, while a larger two-burner design can help prepare several foods at once. The Intcoll listing emphasizes small size and low weight. The Gas One products are portable, single-stove options with carrying cases or outdoor-use positioning described in their product information. BESTFIRE has two burners, legs, a wind shield, and shelves, but it is a bulkier outdoor cooking format.
Consider where the stove will be stored and how it will be transported. For car camping or backyard cooking, a larger setup may be practical. For backpacking, size and weight may matter more, but confirm the actual packed dimensions and weight from the current product listing before purchasing.
How should you compare heat output and controls?
Use stated output as one comparison point, not as a complete measure of suitability. The GS-3900PB lists 15,000 BTU, the Duluth Forge lists 26,000 BTU for heating, and BESTFIRE lists 240,000 BTU for its two outdoor burners. These figures relate to different appliance types and uses, so they should not be compared as if the products performed the same task.
Controls also affect convenience. Both Gas One models list adjustable heat dials and piezo-electric ignition. BESTFIRE lists separate controls for its two burners. Duluth Forge includes a thermostat remote. The Intcoll description mentions adjustable gas pressure for propane, but does not specify an ignition system.
What safety and setup details should you check?
Read the manufacturer’s operating instructions before using any gas stove. Confirm the permitted setting, ventilation requirements, fuel connection, and safe operating distance from combustible materials. Never assume that an outdoor cooking stove is suitable for indoor use. For a gas heater, follow the specific installation and operating requirements and check applicable local rules.
Check whether fuel, regulators, adapters, batteries, or other required components are included. The Gas One listings state that fuel is not included; the GS-3400P includes a propane converter regulator, and the GS-3900PB listing specifies a propane adapter. Duluth Forge’s remote system requires batteries, which the listing says are included.
Frequently Asked Questions
What does multi-fuel mean for a gas stove?
It means the stove is described as compatible with more than one fuel type. The specific options vary by model, so verify the manufacturer’s listed fuels, container sizes, and connection requirements rather than assuming broad compatibility.
Which product in this guide is for indoor heating?
The Duluth Forge FDSR25 is the indoor supplemental heater in this selection. Its listing describes natural-gas or liquid-propane operation and a 26,000-BTU blue-flame heater. The portable cooking stoves are not presented as indoor heaters.
Which portable stove offers the most listed fuel choices?
The Intcoll compact camping stove lists propane, butane, and ISO-butane. Confirm compatible containers and connections in its instructions because the product details do not specify every supported canister or fitting.
Are the Gas One stoves supplied with fuel?
No. The supplied product information says fuel is not included for both the GS-3400P and GS-3900PB. Their listings describe compatible fuel sizes and included propane connection components, but users need to obtain fuel separately.
Is the BESTFIRE stove multi-fuel?
No. Its supplied details describe a propane two-burner stove. It may suit buyers who need high-output outdoor cooking and separate burner controls, but it does not offer the fuel choices listed for the dual- or three-fuel models.
