Great value from Bosch. The Bosch HBM53R550B holds a total of 102 litres across the double oven. It's perfect for large households, and with an A rating for both top and bottom oven, it won't cost a fortune to run either. As a multifunctional oven, you're able to choose which heating elements you need to get better finished on your food; the dedicated pizza setting, for example, uses the bottom element to create crispy bases. There's a defrost setting which uses room temperature air to thaw out frozen food three times faster than leaving it on the side. Plus the stay clean liners absorb grease and dirt, then burn it away so you don't have to clean it yourself.
