The H-KEEPHEAT built-in wi-fi oven from Hoover cooks and preserves food in a way that is said to retain its nutritional benefits.
The oven has a preservation mode, where the food can be cooked at a low temperature, safeguarding it against bacterial growth, and kept for up to seven days.
The 75 litre oven is split over two cavities and has a sleek black finish. Cooked food can be sealed in vacuum bags, kept in a refrigerator and then reheated.
