A: Many manufacturers make ranges that have a gas top and either a gas oven or electric oven. The electric oven offers precise and even heat throughout the oven. This is great for multi-rack baking or cooking and requires less movement or adjusting of pans during the cooking process. Alternatively, gas ovens are great for roasting meats because they give off humidity in the combustion process, which helps retain moisture in meats. Many gas ovens have an optional convection fan that ensures even heat. Gas ovens also come with features such as self-clean, electronic timers and temperature probes. Having an appliance professional properly qualify your needs ensures you have the best cooking experience suited to your lifestyle.
