I don't have one (though I have a KA fridge and it's great), but there is an unusually long thread I'l link below about the Kitchenaid ovens and self-cleaning that may be of interest to you. Here is a link that might be useful: Thread about KA Ovens

I own a 36" Wolf DF and am one with porcelain issues. I love the burners with a great low heat and the oven is wonderful. I am looking to replace it though. After dickering with Wolf they have agreed to provide the part and $350 in labor. The problem is the labor starts at $800+ because they don't know what they will find and the time may vary depending on how fast the guys work. They will only guarantee the part one year. They used to replace ovens with this problem even when 4+ years old for a small fee. Most posters here and elsewhere have had more than one replacement and the replacements don't last as long as the one before. I don't want to risk inhaling or ingesting tiny glass shards when the liner starts to degrade. "I thought electric was a more consistent, and therefore better, option for baking/roasting? " "gas is better for roasting because of the moist heat. " Consistency has nothing to do with gas or electric, but bulk for thermal stabilization (providing radiant heat), air movement within the oven chamber(providing convective heat), placement of burners and accuracy of thermostat. Some companies seek to improve this by adding among other things,more insulation, more bulk, fan(s), a third and possibly a fourth element with computerized controls and and a thermostat with a narrower variance from the set temperature. When looking at humidity in an oven, you have to look past the immediate heat source and look at what happens with the oven and the cooking process. In general a gas oven has more ventilation through the oven chamber so the water that is a product of combustion is vented out along with more heat, so the heat is drier. Electric ovens are not ventilated as much so hold moisture from cooking. The moisture in the electric oven is beneficial the first half of baking breads and cakes because it allows the dough/batter to expand a little more, promotes starch gelatinization and allows better heat penetration of what you are baking. "Dry" is better the second half of the baking process. People seem to pay more attention and it makes more difference for bread. There are many ways people use steam for bread. "Dry" heat from a gas range or using the convection mode on an electric stove gives crispiness to a roast and may be better for some cookies, pies etc. External moisture has nothing to do with internal moisture of a roast. The amount of internal moisture is due to the temperature of the meat. Plus you have to pay a huge premium for dual fuel when in fact it does not cost the manufacture a lot more to make. You pay a premium for the additional elements, fans and the computers to make them run correctly. It would be up to the individual to decide what is huge and if it is worth it. They have fantastic 23k btu open burners with very even heat. No need for high maintenance tin lined French copper pots. What the heck does this mean??? If you have a burner with a flame pattern of 5-6 inches wide, if you use anything wider than 8 inches, you will benefit from a pan that has good heat conduction. Best is heavy gauge copper, lined in tin or stainless. Not everyone polishes. You can also get plied cookware with copper that goes in the dishwasher. Cheaper is aluminum available in several configurations including plied cookware. This is a very biased statement from a sealed burner owner that thinks dual stacking makes any meaningful difference. The purpose of dual stacked burners is to provide two separate burners each with its own range of heat. You would have to look at the range of BTU output for each burner to see the benefit. Rating by temperature is meaningless. I might have a BTU output of 325 and the temperature of what I am cooking could be 190 or 80 depending on the pan and what I am cooking. CC's 23k btu burners are capable of 145 degree simmer which is more than reasonable. Other than raw foodist, virtually no one needs or can use Wolf's 100 degree simmers. This is unbelievably presumptuous to pontificate about what other people should or should not find useful in their kitchen. I use low heat daily for -cooking a whole dinner or pot of soup in a LeCreuset pot using minimal energy -serving off the range, no worries about any scorching pastas, mashed potatoes etc -a short term sous-vide -anything that used to require a double boiler A few weeks ago I was making a syrup that had to be held hot while another step in the recipe was completed and even with the low simmer, it would not stop boiling. I could have "used" even lower heat. There is a whole big world of people that cook in many different ways. Wolf's sealed burners will not give you a decent stir-fry or Pittsburg steak while the CC will. Cooking is about the temperature of the cooking surface. The source of heat is just one component of this. A cook who understands how the properties of cookware work as well as how what you are cooking comes into play will be able to combine these things to come up with the right temps for the cooking surface on both high and low end. You can find blogs where cooks preheat cast iron to extremely high temps by low powered burners to cook pizza. Some restaurants cook a steak on a rock table side with no flame underneath. You just need to understand how to accumulate heat in your cooking surface. How are those pictures representative of the burners referenced? The CC is way off. I have cooked on many different open and sealed burners over 50 years. I agree with weissman that ease of cleaning burners depends on the build and also has a very subjective component. I think you have to avoid generalizations. Even the black enamel on the Dacor range we had was much more difficult to clean than the black on our current Wolf. This, an observation from my husband.

@Heather Spencer I'm not a pro but I dove into the ventilation question a bunch when I was looking at what to do in my own kitchen. There are a ton of posts on it here, too. ventilation is pretty location dependent as far as what you can get away with, but what you should do is use a hood that's sufficient for the range you buy, and provide the makeup air system that's required for it. If you are anywhere that has cold seasons, or if you live in a tight house, you need to have makeup air. Passive systems work in temperate climates, but not so great in cold climates. The makeup air system is designed to prevent a backdraft situation with combustible appliances. In a cold climate with good insulation, houses don't leak, which means your hood vent will suck more air from your house than can be replaced by leaky doors and windows, causing a dangerous situation. The higher the CFM, the harder it is to replace the air without a system in place (gas dryers, gas water heaters, gas fireplaces, and even bath fans contribute to this calc). For a 48" range you need a serious range hood (Wolf recommends 1100 CFM for their 48" range if I remember correctly). Anything over 400 CFM typically requires makeup air. I ran through the calculations in the code in my state when I was trying to decide on a range and found out that it didn't take much to throw me into full makeup air system, so I decided to go with induction. If you choose a 48" range and pick a lower CFM range hood, you'll end up with smells and smoke, unless you just have the range because it's pretty and don't do more than boil water or make grilled cheese on it. So, in order to do it properly, it costs money. More in cold climates, where makeup air needs to be heated. Less in temperate climates. My builder estimated about $5-6k for the makeup air system (not including hood). I priced out what I would need from fantech, and it got me close to that number. So it is true that the ventilation + hood can be as much if not more than the range itself. ETA: this isn't specific to 48" ranges - Wolf recommends 500 CFM hoods for their 30" dual fuel range, so it's more about the power of your range than it is about the size of it. But generally the bigger your range, the more power it has.

I have a 48" dual fuel Hallman and LOVE it! I ordered it 2.5 years ago, but it's been in use for only 9 months. The double ring burner (2) is amazing at getting water boiling, and 1 of them allows to turn it down to a very low simmer for rice. The griddle is roomy and heavy duty. The oven even has a rotisserie (haven't tried it yet). I use both oven sizes equally. It's a beauty, and a joy to cook with...I cook every day for a family of 6.
