toomuchremodeling, I hope you don't mind if I answer and making the assumption that all functions work as they are supposed to, the Dacor has some good ideas. I have cooked on both, although I had the 36" range with 2 16" platforms and 4 11" platforms. I like the idea that they utilize the 16 inch platforms on Dacor. That gives you 6 big burners on the 48" Dacor and 8 conventional burners on the Wolf. I really liked the 6 big burners but wanted 2 full sized ovens so went with the 36" range and wall oven. I frequently cook for 20-30. If you cook with really big pans this is a good idea. I liked the burners, they were great for cooking. The Dacor burners seem to set forward a little more than the Wolf and is more comfortable for me. Wolf also cooks well and has very good simmer and most of my pans have fit well. One problem with the Dacor is that the knobs are plastic,so that they can have the pretty blue light, but one broke and I am careful. Wolf is made with heavy cast metal. Maybe someone might be able to talk about the differences in the burners or maybe a sales person might be able to show you. The Dacor oven is supposed to be within 2 degrees of the setting so comparable to the Miele in accuracy. If you turn the Dacor to 350 degrees, it will do that and if you bake something at that temp, you would say this works great, I love it. The problem was for me on the wall and range oven if you opened and closed the oven for batches of cookies or put something really cold there was no way for the oven to kick on and add a lot of heat(like the typical preheat on any other oven), it had to oscillate and would take 1 hour to move 50 degrees. They admitted this was an issue(even a benefit because my food would not burn with the preheat coming on) and sent improved boards to fix it. Well it didn't burn my food because it didn't even cook it. They never could fix either appliance. There is a cooking school of all things near me that has the same issues with their ovens and can't get them fixed and just try to adjust the oven themselves and add cooking time. Hopefully this has been totally reengineered, but I would make sure that it has before you buy it if you are a serious baker. Also be aware that the boards were billed at $1800.00 each time they were replaced. This was under warranty but if it weren't...ouch. A friend of mine had her board go out on an older Dacor oven and her husband replaced it for $35 on ebay. The computer board on the Dacor gives it some additional functions but can be expensive. The Wolf holds a temperature great. I think the Wolf bakes more evenly in convection because it has the dual fans as opposed to the single fan in the Dacor. If you want to raise the temperature by 50 degrees with the Wolf you have to turn it off and then on to get the preheat to come on. I do like the glide rack for the bottom on the Dacor but also like a regular rack because I am always changing them around. Someone told me Wolf is coming out with glide racks too if you like those. I think the preheat is pretty long on both for the oven to stabilize. One other thing on the 48" range is take the pans you use in and make sure they fit in the small side. Some of the 48" ranges allow more room on the small side and leave some room for circulation.

I installed a 48" DCS in my last house (full remodel). Using propane. I had a giant propane tank that I never needed to refill in those 3 years. I chose it based on Rosengarten and its BTUs. I never had a single problem with it that needed to be fixed. But I don't think I would go DCS again. Firstly, because you can get 18,000+ BTUs from other ranges these days (my DCS was 3 years ago). Secondly, because the flame diameter was too darn wide for anything less than a 10+ inch cooking pan. Yes, I know I can turn it down, but what is the point of 18,000 BTUs if you have to turn it down because your pan is too small??? I have 25 year old LeCreuset pans that are still going strong and I like using them. The only way I was able to crank up my DCS was with a wok, a stock pot or my enormous LeCreust dutch oven. Or my copper crepe pan, but that would ruin the crepes! Also, the grates sit much closer to the flame, so the "flame spread" or whatever it is called is greater. Basically, you have to use really big pans or use really low (relatively speaking) heat. Simmer worked great. I could wok with the best. I had 4 burners, a grill and a griddle. Rarely used the grill because my @#$% Vent-A-Hood that the salesguy assured me would be more than adequate was not. Plus the grill heat was kind of uneven. The griddle took FOREVER to heat up and was very hot at the top and very not at the bottom. Plus it was a pain to clean. So I didn't. I can't comment on the DCS ovens, as I had the rangetop and wolf double ovens (which I loved, but in retrospect not sure they were worth the extra money). There are currently other ranges that get you the BTUs with better flame configuration (Blue Star, Dacor, and Wolf all gas come to mind...).

"Commercial bakeries use nothing but gas ovens." This is not true. If you are talking about bulk bakeries, they are more inclined to because it is often cheaper but they also have steam injectors to add humidity when needed. I know several specialty bakeries that use electric ovens. Many deck ovens in commercial kitchens are electric. I knew of a bakery that was called "the Electric Bakery". It really depends a lot on what they are baking. I know a baker that has specialty ovens for pies. This really has nothing to do with home ovens because they are a different breed anyway as they are expected to do many different things. "Dual fuel is excessively expensive, and overly complex for no benefit in performance ." Performance is different things to different people. They have different needs so there is no one size fits all. If I were selling appliances, the first thing would be to assess that person's needs and make individualized recommendations based on those needs. I most likely would never recommend ranges to begin with unless there was a compelling reason like space or cost issues or even a preference for "looks" over cooks. Pick out each component because it meets individual needs in the best way possible. As far as cost, you can buy electric ovens with features that have high utility for less than some gas ovens with limited features. Electric ovens can be complex, but so are our home computers and cars these days. This is not necessarily a bad thing. These ovens can have features that many consider helpful in how they use their ovens. It takes a computer board to coordinate fans, heating elements and tight temperature control. I love being able to control the direction of heat and fan speed in my oven. I can have air movement slow or fast to facilitate browning or not if I am baking a cake. It has a lot greater range of temperature, with or without the fan than many ovens gas or electric that cost a lot more. There is a learning curve with these features especially with the many choices something like Gaggenau or Miele give you. The combi oven is the king of control of the cooking environment but not in a range yet. The other side of the coin is some ovens have this figured out and others, not so much, so you have to read as many reviews as you can. To minimize risk if you want these features, buy the longest service agreement that you can. They can be difficult to evaluate and compare because a feature named the same name in two different brands can mean two different things. Even the term "dual fuel", in most ovens it means gas burners and an electric oven but 5 Star when they say dual fuel means a gas oven and electric oven together in the same range. You have to decide what is a benefit and what is a burden? No one answer. "could you please explain why all gas is fine" "All gas is fine." I might agree with that statement depending on how you use your oven but that in no way means they are the same and it in many cases gas is not the best choice. Gas and electric ovens are constructed differently. Because you have combustion for your heat source, another difference, gas ovens are vented more to remove products of combustion including water, so those products of combustion and humidity from food move out of the oven and into the kitchen. That may be good or bad depending on where you live, but how is that significant to cooking? It is much more difficult to keep added steam in a gas oven if you are doing that for bread or adding a pan of water for cheesecake. Because there is more of an air current, in a gas oven, this removes more moisture from the surface of what you are cooking. This inhibits starch gelatinization during the first part of baking so inhibits rise and changes the appearance of what you are baking. On the other hand, because it evaporates moisture from the surface and allows it to heat more quickly, the Maillard and other browning chemical reactions take place more quickly. This is why meat, vegetables and even baked goods brown more quickly. Will you notice? A lot of people say they don't. I have baked in gas and electric ovens for over 50 years and I used to attribute differences in outcomes to different ovens rather than a difference in fuel but with the many books and websites that have come out on food science, you can see the rationale for the differences in outcome that cooks report in cooking/baking forums. It was kind of a "aha" moment to put these comments with the science. All of the information coming out challenges what used to be conventional wisdom and yet it might be hard to see if you are not baking the exact same recipe side by side. You do see the same observations cooks make repeatedly in terms of cooking on cooking and baking forums and people seem to notice the difference more coming from electric to gas but you do see the occasional comment about excess moisture in some electric ovens when they are coming from gas. Most advertising literature and websites about ovens actually say a gas oven provides moist heat and electric dry but they are only looking at the heat source and not the oven as a whole and the process of cooking which provides a lot of moisture to the oven chamber. Another difference is that there are more and more features being loaded into ovens now as noted above, mostly electric but sometimes gas too. Some electric ovens have added steam. Combi ovens are very useful in their ability to control humidity and really make the case for buying ovens separate from the range top instead of having to pick the priority of the burners or the oven. I am not a fan of the current trend of hiding the bake element in electric ovens. Sometimes with pies, you need that bottom element exposed. It used to be you could put a tray under the element to catch spills. If you put it on the bottom now, it will melt. Some other things to consider. gas broilers are of two types. There is the traditional gas broiler, but they are not very good. Many prostyle gas ovens have an infrared broiler. They are very hot and even, but can be small. They are great for a couple of steaks but not so much trays of appetizers or broiling larger amounts. How big is the oven? Do you want a quick preheat or need room for full commercial sheets? Look at the rack size for usable space and size top to bottom. What is the temperature range, lowest and highest? What are the increments that you can set your temperature? 25F or 5F? Ovens are not an easy choice these days but I think it helps at least some people to realize the differences so you can at least make a somewhat informed decision.

I don't have the range, but based on my most recent experience with Miele, I would not purchase without the extended warranty unless you get an amazing price (which I doubt).
