Some surface units require specific materials. Some ranges have signal devices to warn you when burners are hot. Some burners are designed to heat up and cool down quickly. You may want warning devices that tell you a surface is still hot. Consider the effect the vent and air draw has on your whole home air movement.
Vents remove cooking odors, smoke, humidity and air-borne grease and other cooking pollutants.
Refer to a consumer magazine or book for comparison studies about ranges. Check with your library or local Cooperative Extension office. Elements, space alongside and range hood must be large enough.
