Q:Does the Speed Oven Model# HMC80252UC/06 need a separate electrical connection with a 4 wire single-phase AC? Or, is it designed to directly plug into the back of Model #HBL8753UC/05 and use one 4 wire conduit cable to operate both ovens?

          Loving my combo oven!
          [This review was collected as part of a promotion.] This oven has so many features! I haven't been able to bake in years due to my out of date oven but now I can bake anything with now worries! The look really made my kitchen, we are in love!

            Made our Kitchen complete
            This unit replaced a 15 year old double oven that no longer served the purpose. What a fantastic product. Installation was simple and it fit in the double oven cutout without needing any alteration. The Microwave portion works really well and is exactly the correct height for use. We really love the quick 30 second reheat button. The oven is also fantastic. This oven maintains the exact heat that you set it for, no variation. You can rely on it to cook in the right amount of time and at the correct temperature.

              Great and Efficient Combination Oven
              [This review was collected as part of a promotion.] This is the best combination oven on the market. The wifi app lets you preheat, start and time your cooking. Not only is it the most efficient oven, it is also very nice looking in my kitchen.

                Double Oven
                [This review was collected as part of a promotion.] It's the best thing ever!! To have 2 ovens, microwave, convection and conventional. It's gets no better than this. The icing on the cake is that I have the app to turn on before I get there to cook dinner right away. Love Love Love ❤️

                  Love everything about it (except the volume)
                  [This review was collected as part of a promotion.] Absolutely LOVE my wall ovens! The only negative is the volume. I have it on max and it's very difficult to hear if there is any noise in the house.

                    Worth the money
                    Cooks efficiently. Offers a variety of ways to cook. Large capacity oven.
                      Elegant and functional
                      [This review was collected as part of a promotion.] We couldn't be more pleased with the Bosch 800 series oven. The black stainless steel fits in with our decor in our kitchen beautifully the functionality is superb, and I love the fact that it talks to my phone via the Internet.

                        Paint chipping
                        Hi, Has anyone had problems with the the paint chipping on the bottom part of the oven after they self clean it? The company states they believe I put something on it or scrubbed with a cleaner which I did not. I am so upset because this oven is so expensive and is considered high end.

                          Excellent Purchase
                          [This review was collected as part of a promotion.] The double oven combination was the perfect addition to our kitchen. Preheats at a fast rate, cooks food evenly, and the look of it is stunning.

                            In-Wall 800 combo oven is great
                            [This review was collected as part of a promotion.] We had great patience in waiting for our black stainless HBL8743UC (16 months-long) 800 series wall oven. It was worth the wait. It completed our new appliance suite. The black stainless is very pleasing and functionality of the upper and lower units are awesome. It is pricey, but all 800 series products are. No issues thus far (4 months).
