Built-in appliances are hard to buy. Most appliance stores are focused on washers, dishwashers, refrigerators, and basic stoves, so it is hard to see one.
Many of the well-known commodity brands like Whirlpool, GE, Maytag, LG, and Samsung are not popular for built-in appliances either.
So you can’t rely on what's in your kitchen and laundry to dictate how you should buy a built-in cooktop (or wall oven).
Most salespeople can’t impart real information either. You will probably not buy a cooktop on your first trip to a store. You will also need specs, qualified installers, and plumbers as this is a more detailed purchase than a standard dishwasher.
Most commissioned store associates do not perceive it as worth their time.
Let me make your cooktop purchase easier for you. Think of your cooktop purchase as comparing half a stove.
Sure there are other considerations, but that’s all a cooktop is. Now 36 inches is a slightly bigger size, but it's the same principle.
That said, in this article, you will see a comparison of two of the industry's best, Thermador and Wolf.
We will look at the layout, BTU output, and simmer as well as reliability based on 34,687 service calls logged by our service department last year.
Before we start, you should understand the differences between rangetops and cooktops because they have different features and are installed much differently.
The terms are used interchangeably and should not be. You do not want to discover the difference upon delivery.

As we said before, cooktops are the tops of stoves, so rangetops are the tops of professional ranges. They vary in size, features, price, and installation.
A cooktop is available in 30 and 36-inch sizes. There are some smaller 24-inch sizes, as well. Rangetops are available 24 and 30, but 36, 48, and even 60 inches are the more popular sizes.
A cooktop like a stove is all burners. The rangetop is available with a grill, griddle, Frenchtop, or all burners, so it is more versatile.
A cooktop will have 1 or 2 high output burners of 15,000 BTU or more in a 36-inch size. The rangetop will 3 to 6 depending on the configuration.
As an average, the rangetop is $500 to $1,200 more than a cooktop.
A cooktop is cut into the countertop. However, a rangetop is slid on the cabinet itself. This is a huge difference, so you want to be careful.
Now, let’s look at Thermador's and Wolf’s gas cooktops.
Wolf has one model, but two different styles as Thermador has 3 models, one style.
For this comparison, we will cover their two most popular gas cooktops.
Let’s look at the companies first.
Thermador is part of BSH Home Appliances Corporation, a fully owned subsidiary of BSH Bosch. Did you know they are the 3rd largest appliance manufacturer in the world?
Founded in 1916 in California by William E. Cranston, and began as a manufacturer of electric items, most notably portable and built-in heaters.
In 1932, Thermador established its appliance manufacturing as Cranston merged with business owner H.H. Fogwell to form the Thermador Electric Manufacturing Company.
Along with Jenn-Air, Thermador was the first American premium appliance company.
Notable personalities such as Julia Child used Thermador ovens in her critically acclaimed PBS TV series, and Alice from the Brady Bunch cooked with Thermador appliances.
Features:
Notice how there is a small and large burner in the front, perfect for paying close attention to a simmer or boil. The largest center burner is 15K BTUs.
Exclusive 200 BTU ExtraLow® burners for perfect simmering. The medium burners in the bottom right and upper left are 9,100 BTUs. And the smallest is 6K BTUs each.
Why You Might Like About This Cooktop:
The surface grates offer an extremely large usable area since they are larger in areas where other cooktops aren’t.
Burner configuration allows 3 large pans to be on the same surface without any interference from each other.
Burners sit on their own pedestal bases, making it less likely that you’ll burn food onto the surface top from any spills that may occur.
The illuminated surface for the knobs give this cooktop a premium feel and clearly displays which burner is in use.
Why You Might Not Like About This Cooktop:
The Extra-low burners claim a 200 BTU output. However, they cycle on and off (going off and reigniting), and are only available on two of the 5 burners.
For some, the inconsistent heat from cycling may not be ideal for certain dishes.
The Sub-Zero Freezer Company was founded in 1945 by Westye F. Bakke in Madison, Wisconsin.
For more than 70 years, Wolf has been synonymous with professional cooking equipment for restaurants and hotels.
In March of 2000, the company became part of Sub-Zero and was adapted for the serious in-home cook.
Sub-Zero/Wolf is now the second-largest family-owned appliance company after Miele.
Features:
Why You Might Like About This Cooktop:
Whether you are cooking for the first time or the thousandth time, the range of high and low output on these burners offer the greatest amount of forgiveness and flexibility for high and low heat.
You can choose colored knobs from red, black, and stainless steel to better match your taste and decor.
Why You Might Not Like This Cooktop:
Compared to the Thermador, you have one large burner ( although 3,000 BTU hotter), one medium burner, and three small burners.
Whereas the Wolf has one large, two small, and two medium burners. Having three large pans with high heat isn’t feasible with the burner layout.
With such a small difference in price, there isn't a bad choice.
Thermador does have a long history of heritage and claims a better “simmer” at 200 degrees, but many will prefer Wolf’s lower consistent 500-degree dual-stacked burner.
Wolf's knobs being set to the right make it less likely to be bumped by a big pot or pan being put on or away from the cooking surface.
The Thermador’s knobs are in the front, which may or may not pose an issue to some cooks.
The Thermador’s range of BTU’s allows the lowest simmer and highest power of the two.
Wolf has now updated its highest output of 15,000 BTUs to 18,000. The Wolf’s grates are heavier and of better quality.
Wolf is over 2% better based on logged service calls last year. Most of the issues in gas range igniter and ignition systems.
