I am interested in this same questions as well. I've also seen varying information about whether a 240v oven can be under counter, versus having to use a 120v oven. Not sure if that is true or not?

Not much help but I have not noticed mine getting hot enough to be worrisome at all.

It won't be too back breaking to get things in and out of it since you can't fit anything too large into it. The controls are at the top and if you mounted it right under the counter, I think it would be okay. For ease of use concerns, it would be pretty much the same as any undercounter oven, but slightly better than a large one.

The only concern I would have is that you'd have to bend over to look at your food cooking. I have to look at my stuff in the Miele more than my other oven because I haven't figured it out yet. :P

I looked at the miele and bosch speed ovens today in person, the bosch seems like the layout would useable undercounter but less than ideal positioning for something I'd probably use a lot.

I did not like the controls on the miele version with knobs at all, seems like a big pain compared to a "normal" MW. The bosch was more of a normal MW control scheme. They didn't have the touchscreen version to test out.

I think the only 240V that are usable undercounter are Summit, Miele, and Bosch. That's what AJ Madison website says at least.

I'm wondering if I can stack the Bosch SO with the Miele coffee maker and have it not look stupid...

What is the difference concerning placement with an under counter speed oven and an oven on a regular range? Those who have wall ovens might see bending over as an inconvenience, but I've had to bend over to look at my food and reach down to put things into/take things out of my range's oven forever so I've never thought of it as being an issue.

I thought the same thing, but it is a little different. Few things I think

1) where the controls are, when you use a range you don't have to bend over to see the controls. the controls on a speed oven are relatively complicated given all the different things it can do.

2) the microwave is shorter amounts of cooking and I think in general requires more eyeballing more often than you typically need with a regular oven. 30 seconds in an oven doesn't make much difference... in a MW, it can.

3) usually in an oven you are using a baking dish, cookie sheet, etc that are meant to be put in an oven... not putting in a mug or small plate or bowl or whatever as in a MW.

I didn't consider that you'd be using it as a microwave--I don't think I'd like that under the counter as well as a normal oven. (I've had mine a while but haven't been convinced to put the regular microwave away just yet...if you're using it as your microwave, I find the Miele to be too much trouble. I have the cheap one with the knobs because it looked better to me, but I should have checked the functions better.)

I am interested in the same question as I currently have a Miele speed oven that I want to keep in a renovation and move under counter. I did find an older thread where this was discussed and some that had it were happy with it (try to search Miele speed under counter). That being said right now mine is the upper in a stack and it is handy having it at that level. But I will have a combi steam in that position in the new setup that I expect to use more. In the new setup the speed will be a third oven working mostly as a microwave but also available for the speed functions and a third oven at times.

What at I did want to comment upon is the controls and using it as a microwave. I have an master chef version with no knobs. I believe this will be fine under the counter for microwave use as we ONLY use the minute plus button for microwaving. The only thing we use a microwave for is reheating usually single serve plates of food, a bowl of soup etc.. On our version the minute plus actually adds 30 seconds (it might have been a setting to pick 30 over a minutes I don't remember). So pretty much all we do is hit it a few times as nothing I do needs more than a few minutes nor more precise timing than 30 second intervals. When I do use it as an oven controls under counter might be a bit harder but I expect I'll use this for set and leave stuff like baked potatoes (although I love using the function on that when I can set ho long to cook and what time I want them done so a bit of setting up front but then I just leave them until done. I often put them in well before dinner knowing they will turn on at the right time).

I've had under counter microwaves in my last two homes (not drawers). I don't like it because I hate bending. However, even though I'm not a fan, it's really no big deal and it doesn't impede it's use at all. If you hate bending like I do, then yeah, you might not be fond of it, but I think you'd still find it very doable (if I can do it, anyone can!). If you don't mind bending, then I wouldn't think you'd mind it at all. My friend put a Gaggenau steam oven below her counter and she doesn't regret it.

Just keep in mind there is no rack to pull out like in an oven. The Bosch's door does open like an oven but then you have to reach in to get whatever is in there.

any suggestions of Miele vs Bosch speed ovens for use under counter? I'm leaning toward the Bosch because of the price difference.

Curious @DrB477 how you like your Miele coffee maker?
