The type of cooktop you have—whether gas or electric—directly determines the ideal specifications for a custom range hood, including installation height, airflow capacity (CFM), and ductwork layout. Because gas and electric cooktops differ significantly in terms of heat output and the volume of smoke and grease produced, their kitchen ventilation requirements vary widely. The following guide outlines key considerations to help you select the perfect handcrafted range hood to match your cooktop.
Gas Stoves
Gas stoves remain the top choice for home chefs for their instant, precise flame control. However, gas combustion generates additional exhaust fumes, intense heat, and significant amounts of airborne grease particles; therefore, a high-performance kitchen ventilation system is essential.
Mounting Height Rule for Gas Stoves
· Standard installation height: 24–30 inches above the gas cooking surface.
· Too high: The vent hood for gas stove setups won't trap rising smoke and grease, resulting in poor suction performance.
· Too low: This creates a major fire hazard from open flames and blocks your daily cooking workspace.
CFM Power Recommendation
Because gas releases more combustion byproducts, it requires a stronger kitchen exhaust fan airflow:
· Standard residential gas cooktop: A custom range hood requires an exhaust capacity of at least 300–400 CFM (cubic feet per minute).
· Professional-grade/high-output gas cooktop: An upgrade to over 450 CFM is necessary to handle the high heat generated during cooking.
Tips: Choose a high-quality custom exhaust system equipped with a multi-speed fan; this allows for easy airflow adjustment whether you are slowly simmering a sauce or deep-frying at high temperatures.
Electric Stove
Electric cooktops—whether smooth glass-ceramic or coil-element models—provide consistent heat without generating the exhaust byproducts associated with gas combustion. Although they release less heat into the surrounding environment than gas stoves, the steam and grease-laden vapors produced during cooking (especially frying) still require proper ventilation to prevent moisture damage and maintain fresh kitchen air.
Mounting Height Rule for Electric Stoves
· Standard installation height: The same 24–30 inch benchmark applies to an electric stove range hood for effective steam capture.
· Why it matters: Selecting the appropriate installation height prevents steam from condensing on the range hood's cold metal surfaces and subsequently dripping back onto your freshly cleaned stovetop.
CFM Power Recommendation
Electric cooktops have a lighter overall ventilation demand:
· Standard household electric cooktop: 200–300 CFM fits most daily home cooking needs.
· Pro Tip: A variable-speed fan is still highly recommended so you can switch between low-noise simmering and heavy-duty frying.
Extra Buying Factors
Ducted vs. Ductless Range Hoods
· Ducted range hoods: These hoods vent grease, moisture, and stale air outside through the kitchen's ductwork. They offer better performance and are ideal for gas stoves and heavy-duty cooking.
· Ductless Range Hoods (Recirculating Hoods): These filter the air through charcoal pads and recirculate it back into the kitchen. They are perfect for apartments, condos, or kitchens lacking external vents, and work well with electric stoves.
Conclusion
To summarize: gas cooktops require higher airflow (over 300 CFM), while electric cooktops require moderate airflow (over 200 CFM). Both perform optimally at a standard installation height of 24 to 30 inches. Based on this, you can choose between ducted and ductless configurations to suit your kitchen's layout.
