Gas ovens can vary in temperature considerably during its cycles. An electric oven varies much less on average. Gas elements, however, have many advantages over electric. Heat changes are almost instantaneous, whether the heat is increasing or decreasing. You can see why it makes sense to combine an electric oven with a gas stovetop when you love to cook.
Often called ‘dual fuel ranges', these appliances come with a huge choice in variety of features. Because experienced cooks are attracted to two fuel types of ranges, many high end models are available with advanced features. Some of the features include a side oven or double oven, electric griddles, low heat gas technology (for slow simmering on the stovetop), convection ovens, bread proofing controls, delayed start, and many more.
Don't worry if you are only looking for a basic model - there are many entry level models too. Prices are generally higher for these types of ranges. Whether the advantages are something you need is purely a personal decision.
If you need to replace your range, consider dual fuel - it may be well worth looking into.
