Cooktops

Gas and electric cookers are the most common today.Both are equally mature and safe, and the choice between the two is largely a matter of personal preference and preexisting utility outlets: if a house has no gas supply, adding one just to be able to run a gas cooker is an expensive endeavour. In particular, professional chefs often prefer gas cooktops, for they allow them to control the heat more finely and more quickly.  On the other hand, some chefs often prefer electric cookers because they tend to heat food more evenly.  Today's major appliances brands offer both gas and electric stoves, and many also offer dual-fuel stoves combining gas cooktops and electric ovens.

Oven

Modern ovens are fueled by gas or electricity. Oven's usually can use a variety of methods to cook. In order to provide faster, more-even cooking, convection ovens use a small fan to blow hot air around the cooking chamber. Steam ovens introduce water into the cooking chamber.  More modern ovens, such as General Electric's Trivection oven, may also provide combined thermal and microwave cooking. This can greatly speed the cooking of certain types of food while maintaining the traditional characteristics of oven cooking such as browning. The simplest oven's may not have any controls at all; the several appliances simply run continuously at various temperatures. More-conventional ovens have a simple thermostat: this both turns the oven on and off and selects the temperature at which it will operate. More-sophisticated ovens may have complex, computer-based controls allowing a wide variety of operating modes and special features including the use of a temperature probe to automatically shut the oven off when the food is completely cooked to the desired degree. Some ovens provide various aids to cleaning.

Extractor hoods

There are 2 major applications of extractor hoods: ducted (or vented) application, and ductless (or recirculating) application.In a ducted application, the output collar of the extractor hood's blower motor is attached to a duct system, which terminates outside of the residence. In a ductless application, a filter containing activated charcoal is used to remove odor and smoke particles from the air, before releasing the cleaned air back into the kitchen environment. 
A ducted application is generally preferable, since it allows for removal of all forms of airborne contamination, while ductless application recirculates heat into the kitchen environment.
In addition, a ducted application eliminates the need for replacing the activated charcoal filters on a regular basis, and avoids the airflow restriction caused by activated charcoal filter placement. Some range hood designs allow for both types of applications, and are typically noted as such in the manufacturer's product literature. Exhaust hoods often include built-in lighting.
