The 3 Oven Aga Cooker

The 'Best of Both Worlds'!


The 3 oven Aga range cooker was released in 2003 and revolutionised Aga cooking. No more faffing with the cold shelf to moderate temperatures without compromising on space. Taking up the same footprint of the 2 oven model, it comes with 3 large ovens. A high-temperature roasting oven, a low temperature simmering oven and a moderate temperature baking oven. Each of these has the dimensions W: 349mm x H: 254mm x D: 495mm.

The roasting oven (top right) has an average temperature of between 220c-240c (depending on the shelf position inside the oven). The simmering oven (bottom right) sits at 140c. The baking oven (bottom left) is around 190c. These are average temperates and they will fluctuate slightly.


The 3 oven also comes with the classic 2 hotplates for pots and pans (boiling on left at around 315c, and simmering on right at about 215c). The control door (top left) houses all of the controls you need for setting the temperature. 3 Oven models are available in Gas, 13amp Electric, Controllable ElectricKit. Aga Rangemaster did release an oil version but it proved to be problematic as the oil line couldn't be gravity fed so it was quickly pulled.


The 3 oven model is extremely popular since it incorporates the size of the 2 oven with the added functionality of the baking oven. These models can be hard to find on the reconditioned market due to their young age and popularity.
