The AGA eR7 Series can be left on 24/7, especially during those cold winter months, providing that useful background heat. These models are so flexible they allow individual heat storage ovens to be left on while others may be switched off to save energy. Each part of this cooker works independently, so you can control the heat in your kitchen and the energy that you use. It is a joy to cook with and super easy to control with a touch-screen panel.
