What to know first
- ExtraLow Select is the main reason to choose the Thermador PCG304W: five simmer settings with a stated low of 204 BTU.
- It’s a 30-inch gas cooktop, so fit comes down to matching your cutout and clearances, not just the headline width.
- Thermador positions ExtraLow for keeping food warm without scorching, not just simmering.
- This is a luxury purchase. Make sure your kitchen hookups and ventilation plan match the kind of cooking you’ll do.
- If you rarely cook at low heat, you may be paying for a feature you will not use much.
What the Thermador PCG304W is
The Thermador PCG304W is a 30-inch gas cooktop aimed at high-end kitchens. It’s built around Thermador’s signature Star burner platform and a low-heat feature called ExtraLow Select.
In plain terms, this cooktop is for people who want gas for everyday cooking, but who also want a true “gentle mode” for the stuff that usually burns first: sauces, chocolate, and anything you’re trying to keep warm while the rest of dinner finishes.
Thermador’s lineup includes models with ExtraLow, and the PCG304W sits in that luxury lane. The evidence here does not confirm the model’s exact retail timeline, so I would treat it as a current-style Thermador gas cooktop rather than buying it based on “newest model” status.
Why it stands out
ExtraLow Select is the standout feature. Thermador describes it as five simmer settings with a stated minimum of 204 BTU. That’s the difference between “I can kind of simmer if I babysit it” and “I can pick a low setting and get back to chopping.” The five steps also matter because repeatability is what makes low heat useful. You want to be able to come back tomorrow and get the same gentle result.
Thermador also frames ExtraLow as a way to keep food warm without scorching. That’s a real day-to-day win if you cook in stages, serve family-style, or routinely have one dish ready before the others.
The other reason people buy Thermador is the Star burner design. If you like pro-style gas hardware and you want a cooktop that looks and feels like it belongs in a premium kitchen, this model is built for that buyer.
What it is like to own
Day to day, the PCG304W is about control at the bottom end. Instead of hovering over a tiny flame and nudging a knob, you get defined ExtraLow settings meant to land you in the “safe zone” for gentle cooking. If you make sauces weekly, that changes your routine in a way you’ll notice quickly.
Because it’s a gas cooktop, plan on ventilation being part of ownership. Gas cooking produces heat, steam, and combustion byproducts, and a stronger cooktop can overwhelm a weak hood. If your current ventilation is marginal, you can end up using the cooktop less aggressively than you expected.
Fit is also part of ownership. A 30-inch cooktop is not a universal swap. If you’re replacing an older unit, the practical step is matching the cutout and clearance requirements so you do not turn a cooktop purchase into a countertop project.
What to know before you buy
Do not buy this cooktop just because it says “simmer.” Buy it because you actually cook at low heat and you want defined, repeatable low settings. If you mostly boil pasta, sear steaks, and reheat leftovers, you can get what you need for less money.
Also, remember that gas cooktops still need electricity for ignition and controls. If you are changing fuel type or moving the cooktop location, the electrical and gas requirements can add cost and complexity.
Finally, treat the 30-inch label as a starting point. The cutout size and clearances are what decide whether this is an easy replacement or a remodel-level install.
The specs that matter
This is the standard size for many kitchens, but replacements come down to your countertop cutout and clearances. Measure before you commit.
This is the feature that makes the PCG304W different in daily cooking. It’s designed to deliver gentle heat you can use for sauces, melting, and holding.
Multiple defined steps make low heat repeatable. You can learn which setting works for your pot and recipe instead of constantly adjusting the knob.
A very low stated BTU is aimed at preventing scorching during long simmers and delicate tasks. It’s the number behind the “gentle enough” promise.
This is useful when you’re timing multiple dishes. You can hold a sauce or side at a low level while you finish the main.
This is part of what people are paying for with Thermador. If you want premium gas hardware and the Thermador look, this is central to the appeal.
Who this product fits
You make red sauce, chili, or stock and hate babysitting the pot
The Thermador PCG304W’s ExtraLow Select is built for long, gentle cooking. The point is to pick a low setting that stays in the safe range so you can step away without the bottom scorching.
You melt chocolate or make delicate pan sauces
ExtraLow’s very low stated output and defined settings are aimed at the fussy stuff where a normal gas burner can run too hot. It’s a better match for melting and holding than a typical “low” flame.
You’re building a high-end kitchen and want luxury gas, not induction
If you like the feel of cooking on flame and you want premium hardware, the PCG304W gives you the luxury gas experience while still taking low-heat cooking seriously.

Thermador PCG304W FAQ
What is Thermador ExtraLow Select on the Thermador PCG304W?
ExtraLow Select is Thermador’s low-heat mode designed for delicate cooking. Thermador describes it as five simmer settings with output as low as 204 BTU, aimed at gentle simmering and keeping food warm without scorching.
Is the Thermador PCG304W a good choice if I mostly cook on high heat?
It can be, but the main reason to pay for this model is the low-heat control. If you rarely simmer or hold food warm, you may not get much day-to-day value from the feature that makes it special.
Will a 30-inch cooktop like the Thermador PCG304W fit any 30-inch cutout?
No. “30-inch” is a width class, not a universal cutout. Replacing an older cooktop usually comes down to matching the countertop opening and clearance requirements.
Do gas cooktops like the Thermador PCG304W need electricity?
Yes. Gas cooktops still need electricity for ignition and controls. Make sure you have the right hookup available where the cooktop will be installed.
Do I need special ventilation for the Thermador PCG304W?
You need a ventilation plan that matches how you cook. Gas produces heat, steam, and combustion byproducts, and stronger cooking can overwhelm a weak hood, making the kitchen less comfortable to use.
Should you buy the Thermador PCG304W?
Buy the Thermador PCG304W if you want a luxury 30-inch gas cooktop and you genuinely care about low heat. ExtraLow Select with five simmer settings and a stated 204 BTU minimum is the kind of feature you feel every week if you cook sauces, melt chocolate, or hold food warm while you finish the rest of dinner.
Skip it if you are shopping primarily on price, or if your kitchen setup is not ready for a premium gas cooktop (especially ventilation and fit). In that case, you will be happier putting the money toward a cooktop that better matches your space and the way you actually cook.
