The AGA is a great feature in any home. It provides food, warmth and looks great in the kitchen. It’s been used in homes across Britain since its introduction in 1929 and for many, it’s the AGA that makes a house a home. So why have an AGA? AGA’s baking oven cook’s food evenly from every direction. The boiling plate cooks rapidly, retaining all the foods natural flavor, color and nutrients. The simmering plate gently heats food for perfect tenderness and the simmering oven is perfect for slow cooking.
