Single ovens are shorter than double ovens and can be put neatly under counters. They usually have electric elements at the top and the bottom of the oven for zoned heating. This allows for more precise browning and cooking of dishes. You can cook several dishes at once, saving time. https://ovensandhobs11051.suomiblog.com/can-a-built-in-single-gas-oven-and-grill-be-installed-in-your-kitchen-46379011
