After deciding on the fuel to use, the choice is between a traditional, free-standing stove or a separate hotplate and oven. An all-in-one stove is often cheapest. The advantage of separate units is that you can install them in different parts of the kitchen; the oven can be positioned higher than it is in a free-standing stove to eliminate stooping; and you also have the option of using different fuels, possibly gas for the hotplates and electricity for the oven.
With a separate oven, the grill may be placed either above the hotplate at eye-level, below it or inside the oven itself. Decide how much grilling you do and how inconvenient it would be if the grill were inside the oven. If you have only one oven, it cannot be used for any other cooking, such as baking, while you are using the grill.
There are useful extras which are worth considering. You might want a self-cleaning or stay-clean oven, a motorized rotisserie or an integral charcoal-style grill. There are also built-in wok stands, or deep-fryers connected to extraction units to eliminate smells. Some ovens have optional bread or pizza stones which fit exactly into the oven, heat up with it and provide an ideal surface on which to bake breads and pizza.
