The F965 Dual Fuel Range: 36-Inch Gas Cooktop with Turbo True European Convection Electric Oven
Dual fuel ranges exist because the two most common cooking energy sources each have a meaningful advantage the other doesn’t share — gas delivers the immediate heat response and visual flame feedback that stovetop cooking benefits from, while electric ovens produce more consistent, even heat distribution that baking and roasting rely on. Combining them in a single appliance captures both advantages without requiring two separate appliances or the compromises of choosing one fuel type across the board.
The F965 is Cosmo’s 36-inch dual fuel range, putting five sealed gas burners on the cooktop alongside a 3.8 cubic foot electric oven with Turbo True European Convection and seven oven functions. The included wok ring supports round-bottom wok cooking on the gas burners. Metal knobs control both burners and oven functions, a digital display with clock and timer manages oven operation, and the removable backsplash accommodates both freestanding and slide-in installation. The F965NF adds a lower storage drawer to the specification. LP conversion is available for both models, making the dual fuel configuration accessible to homes without natural gas utility service.
What Dual Fuel Actually Means in Practice
The dual fuel concept sounds straightforward but its implications for daily cooking are worth understanding thoroughly before evaluating whether it suits your household’s patterns.
The Gas Cooktop Advantage: Gas burners respond immediately to control adjustments — turn down the flame and heat output drops in seconds. This responsiveness matters most when cooking methods require rapid heat transitions: reducing to a simmer before a sauce breaks, pulling back from high heat when browning develops faster than expected, or making quick adjustments as ingredients change the pan’s thermal dynamics. The visual flame feedback provides constant intuitive information about heat output that electric cooktops can’t replicate. Five burners across 36 inches also provides five simultaneous gas cooking zones with their full range of heat output available at each position.
The Electric Oven Advantage: Electric oven heating elements maintain more consistent temperatures with narrower fluctuation ranges than gas oven burners, which introduce combustion byproducts and moisture into the oven cavity and sometimes create more pronounced temperature cycling. Electric heat is dry, consistent, and — when paired with a proper convection system like Turbo True European Convection — distributes across the oven cavity more uniformly than gas oven heat. For baking particularly, where temperature consistency affects gluten development, leavening, and browning in ways that require narrow temperature windows, electric oven heat has real performance advantages.
Why Both Together Matters: Most serious home cooks develop preferences for one fuel type on the cooktop while finding limitations in oven baking when that same fuel type runs the oven. Gas cooks who love their burners often find gas ovens less consistent for baking than they’d prefer. Electric cooks who bake beautifully sometimes find stovetop cooking frustrating without gas responsiveness. Dual fuel resolves this by matching each cooking zone to the fuel type that serves it best rather than accepting the weaker performance of either fuel type in its less suitable application.
Five Sealed Gas Burners
The F965’s gas cooktop provides five sealed burners across the 36-inch cooking surface, offering simultaneous cooking capacity for complete meal preparation alongside the heat responsiveness that gas cooking is valued for.
Burner Configuration: Five burners across 36 inches allows a layout that typically positions a high-output power burner alongside medium and lower-output burners in an arrangement that covers the full heat range simultaneously. Complete meal preparation — protein on a high-heat burner, sauces and vegetables on medium burners, grains simmering on a low burner — runs simultaneously without waiting for burner availability or compromising heat levels.
Sealed Burner Maintenance: All five burners use sealed construction that keeps cooking spills on the cooktop surface rather than reaching internal burner components. The practical effect compounds over time — sealed burners remain easier to clean throughout their lifespan while avoiding the corrosion and clogging that open burner designs accumulate when spills reach internal components.
Front Control Knobs: All five burner controls mount at the range front, accessible from a natural cooking position without reaching over active burners. The metal knob construction provides tactile precision for flame adjustment across the full range from minimum to maximum output, and the front position keeps controls away from burner heat that could degrade knob materials over time.
Wok Ring Inclusion: The included wok ring positions directly over the appropriate burner, creating the concave support that round-bottom woks require for stable positioning and effective flame contact. The combination of gas burner output and proper wok hardware geometry allows high-heat wok cooking techniques — stir-frying, searing in a wok, flash cooking vegetables — that flat grates and lower-output burners don’t accommodate as effectively.
Cast Iron Grates: Heavy-duty cast iron grates span the full cooktop width, providing the thermal stability and structural support that serious gas cooking demands. The continuous grate surface allows sliding heavy cookware between burner positions without lifting, and cast iron’s thermal mass helps moderate temperature fluctuations when cold ingredients contact hot pans.
LP Conversion: The gas cooktop converts from natural gas to liquid propane through an optional conversion kit, replacing burner orifices with LP-specific versions sized for propane’s different pressure characteristics. After proper conversion, all five burners perform equivalently on LP as on natural gas.
Turbo True European Convection Electric Oven
The electric oven pairs a 3.8 cubic foot cavity with Turbo True European Convection technology — the same fan-assisted circular heating element system that appears in Cosmo’s dedicated wall ovens, bringing genuine convection performance to this dual fuel configuration.
Why True European Convection Over Basic Convection: Standard convection adds a fan to move existing oven heat around the cavity. True European Convection adds a dedicated circular heating element surrounding the fan, heating air as it circulates rather than relying solely on main oven elements to warm air that the fan then distributes. The result is more uniform temperature distribution throughout the cavity — front to back, corner to corner — than fan-only convection achieves, particularly important in a 3.8 cubic foot space where multi-rack cooking distributes food across the available height.
Electric Oven Temperature Consistency: Electric heating elements maintain temperatures with narrower fluctuation ranges than gas oven burners, which run on/off cycles that create wider temperature swings. For baking specifically — where the temperature window between properly developed and over- or under-baked can be narrow — electric oven consistency produces more reliable results across repeated attempts at the same recipes.
Dry Heat for Baking: Gas ovens introduce moisture from combustion into the oven environment, which can affect crust development on baked goods, surface browning on roasts, and the crispy textures that dry heat produces most effectively. The F965’s electric oven provides dry heat that promotes the surface browning and crust development that baking recipes assume without this moisture interference.
Oven Cavity Cooling Ventilation: The cooling ventilation system manages heat dissipation from the oven cavity, protecting surrounding cabinetry from heat damage while keeping the range exterior at comfortable temperatures during extended cooking sessions. This system runs automatically during oven operation without requiring separate management.
Seven Oven Functions
Seven distinct functions in the electric oven cover the full range of cooking methods that home kitchens use regularly, from basic baking to specialized modes that expand the oven’s capability beyond conventional cooking.
Bake: Standard radiant baking through bottom and top elements, used for conventional recipes and techniques that don’t require active air circulation. Most established recipes assume this mode’s behavior without temperature or timing adjustment.
Convection Bake: Fan-assisted baking with Turbo True European Convection active, providing the even heat distribution benefits that improve consistency across rack positions and accelerate cooking by approximately 20-25%. The everyday workhorse function for most baking and roasting where consistent results matter.
Convection Roast: Optimized combination of element selection and fan speed for developing surface browning and crust on meats and vegetables alongside thorough internal cooking. The active airflow removes surface moisture more aggressively than convection bake, creating the dry-heat conditions that produce proper roast exteriors.
Broil: Top element at maximum intensity for direct overhead high heat — finishing dishes, browning gratins, charring surfaces, and any technique requiring concentrated top heat without full oven cooking temperatures.
Convection Broil: Combines top element intensity with fan circulation for more even broiling results across a dish’s full surface rather than concentrated browning only directly under the element.
Warm: Low-temperature holding mode maintains completed dishes at serving temperatures without continuing to cook them — practical for staging components during multi-dish meal preparation.
Proof: Dedicated proofing mode maintains the warm, consistent low-temperature environment that yeasted doughs require for proper rising — a function that makes bread baking, pizza dough, and other yeasted preparations significantly more reliable than improvised proofing methods.
Digital Display with Clock and Timer
The digital control interface manages the electric oven’s functions, temperature, and timing through an ergonomic display integrated into the range front.
Display Functionality: The digital display shows set temperature, current oven temperature, selected function, and timer status clearly from across the kitchen. Monitoring oven status without opening the door is particularly useful during baking where door openings disrupt temperature stability and affect results — seeing that the oven is actively holding 375°F through the display confirms cooking conditions without intervention.
Clock and Timer: The built-in clock makes the display useful as a general kitchen time reference throughout all kitchen activity. The independent timer counts down without starting or stopping the oven itself, allowing it to track stovetop tasks, side dish timing, or any kitchen timing need simultaneously with active oven operation.
Electronic Temperature Control: Electronic controls set exact target temperatures rather than the approximate positioning of mechanical thermostats. This precision contributes to the consistent oven performance that the dual fuel configuration’s electric oven is designed to deliver, ensuring the displayed temperature reflects the actual target being maintained.
Construction and Installation Flexibility
The F965’s build quality and installation options reflect a range designed to fit different kitchen configurations and hold up through years of daily cooking.
Metal Knob Construction: Metal knobs throughout — both burner controls and oven function selectors — provide the tactile precision and long-term durability that kitchen environments demand. Metal construction holds up to the heat exposure, moisture, and repeated use that knobs experience during active cooking without the softening or loosening that plastic alternatives develop over time.
Brushed Stainless Steel Finish: The brushed stainless exterior maintains its appearance through the cleaning and handling that daily kitchen use involves, resisting the surface wear that lesser finishes accumulate over years of regular contact.
Removable Backsplash: The F965 accommodates both freestanding and slide-in installation through the removable backsplash design. With the backsplash in place, the range stands as a freestanding unit with a finished rear edge and controls positioned at the backsplash height. With it removed, the range sits flush with surrounding counter heights for a built-in slide-in appearance. This dual capability suits different kitchen configurations without requiring separate range models.
Heavy-Duty Cast Iron Grates: The same cast iron grate system that provides thermal stability and structural support on the cooktop also contributes to the range’s substantial, quality feel. Cast iron grates built to handle years of daily cooking use match the dual fuel range’s overall build quality positioning.
The F965 vs. F965NF Distinction
The two F965 Series models share identical cooking specifications while differing in one practical feature worth understanding before choosing between them.
F965 (Without Storage Drawer): The standard F965 provides maximum oven access from below without the drawer footprint, which can allow slightly more toe-kick clearance or suit installations where the space below the oven is used differently. Both models have identical oven capacity, function count, and cooktop specifications.
F965NF (With Storage Drawer): The F965NF adds a full-width lower storage drawer below the oven, providing dedicated storage for baking sheets, roasting pans, and oven accessories that naturally belong near the range. The drawer brings equipment immediately accessible at floor level, keeping frequently used oven accessories organized and retrievable without searching through cabinetry elsewhere in the kitchen.
Choosing Between Them: The storage drawer decision follows whether you have adequate storage for baking and roasting equipment in your existing cabinetry or whether the dedicated drawer solves a real organizational gap. For kitchens with ample cabinet storage near the range, the F965 serves equally well. For kitchens where storage is tighter or where consolidating oven accessories near the oven would genuinely improve workflow, the F965NF’s drawer earns its place.
Who The F965 Dual Fuel Range Serves
The dual fuel configuration addresses specific cooking priorities that make it worth the additional complexity and typically higher cost compared to single-fuel alternatives.
Serious Bakers Who Also Cook on Gas: The most common profile for dual fuel range buyers is someone who has strong preferences for gas stovetop cooking’s responsiveness but has experienced the baking limitations that gas ovens sometimes present. The F965 resolves this without compromise — full gas cooktop performance for stovetop work alongside a consistent electric convection oven for baking results that gas ovens don’t match as reliably.
Households Upgrading From Separate Appliances: Some households run a gas cooktop alongside a separate electric oven or countertop convection oven to capture both fuel types’ advantages. The F965 consolidates this into a single 36-inch appliance, simplifying the kitchen while maintaining the dual-fuel approach that was already working.
36-Inch Kitchens Wanting Both Fuel Advantages: For kitchens with 36-inch range openings — which provide five burners and wider cooking surface than 30-inch alternatives — the F965 delivers that capacity with the dual fuel advantage rather than forcing a choice between gas or electric performance.
Homes With Gas Service and Baking Priorities: Any home with existing gas service where baking is a regular and valued activity benefits from considering dual fuel. The electric oven upgrade over a standard gas range oven is most apparent in baking results, where the consistent dry heat and Turbo True European Convection combination produces more reliable outcomes than gas oven equivalents.
The F965 makes a coherent case for households that have developed clear preferences about how their cooktop and oven should perform — gas burner responsiveness for stovetop cooking, electric oven consistency for baking — and don’t want to accept either fuel type’s limitations across both cooking zones. With five gas burners, Turbo True European Convection in a 3.8 cubic foot electric oven, seven oven functions including a dedicated proofing mode, an included wok ring, and the installation flexibility of the removable backsplash, the F965 Series serves this specific buyer profile more directly than any single-fuel range in the lineup can.
