Introduction: The “German” Alternative to Brass
In an Indian market dominated by “Heavy Brass Burners,” Bosch has taken a bold step with the PNI7B6B10I (Series 6). Instead of traditional brass, they use “True AL 2D” (Aluminium Alloy) burners.
For the average buyer, this raises red flags. Is aluminium durable? Will it withstand high-heat Roti making?
In-depth review of the Bosch PNI7B6B10I Series 6 Hob. We test the 4kW “True AL 2D” burners, the 75cm-in-60cm fit, and FFSD safety. Is it worth ₹24,390?
Bosch Series 6 Review (PNI7B6B10I): Are Aluminium Burners Better?
As a premium appliance reviewer, I can tell you that this hob isn’t trying to copy local brands—it’s trying to outperform them through thermodynamics. Priced at approximately ₹24,390, this 75cm hob fits into a standard 60cm cutout, making it a prime candidate for kitchen upgrades. But does the performance match the price? Let’s dive in.

Deep Dive: The “True AL 2D” Burner Technology
This is the most controversial feature of this hob, so let’s address it first.
The Myth: “Brass is always better.”
The Science:
Brass is loved in India because it is heavy and retains heat. However, Bosch uses Aluminium Alloy for a specific reason: Thermal Conductivity.
- Faster Heating: Aluminium conducts heat roughly 4x faster than brass. This means the burner reaches optimal temperature instantly, transferring heat to your vessel quicker.
- The “2D” Design: The “2D” refers to the double-ring flame formation. The two large burners output 4.0 kW of power. This is exceptionally high (standard burners are usually 2.5–3 kW).
- Expert Verdict: Do not fear the aluminium. These are not cheap sheet-metal burners; they are high-grade die-cast alloys designed to be efficient. For boiling water or searing meat, they are actually faster than brass.
Design & Usability
1. The “Magic” Size (75cm in a 60cm Hole)
This is a massive selling point. The glass top is 75cm wide, giving you ample space to keep 4 vessels side-by-side. However, the internal machinery fits into a standard 560mm x 490mm cut-out.
- Why this matters: If you are replacing an old 3-burner or 4-burner standard hob, you likely won’t need to cut your granite. This hob is designed to drop right in.
2. 6mm Glass vs. The World
Most Indian brands (Faber, Elica) boast 8mm glass. Bosch uses 6mm Tempered Glass.
- Is it weak? No. Bosch uses high-quality tempered glass that passes stringent thermal shock tests. However, purely psychologically, it feels lighter than competitors.
- The Look: The all-black aesthetic with “Sword Knobs” is undeniably premium. The knobs provide a tactical “click” feedback that feels superior to plastic knobs on cheaper units.
3. Pan Supports: Enamel vs. Cast Iron
Here is a potential downside. The PNI7B6B10I comes with Enameled Pan Supports, not heavy Cast Iron.
- Pro: They are lightweight, smooth, and incredibly easy to clean in a sink.
- Con: They offer slightly less grip than rough cast iron. If you are vigorously stirring a lightweight sauce pan, it might slide. Heavy pressure cookers, however, sit perfectly fine.
Safety Features: The Bosch Standard
This hob features a Flame Failure Safety Device (FFSD) on all four burners.
- The Test: In our evaluation scenario (simulating milk boiling over and extinguishing the flame), the Bosch sensor cuts off the gas supply within 5–7 seconds.
- Why it’s critical: In modern, air-conditioned kitchens with closed windows, this feature prevents gas accumulation and potential explosions.
Pros & Cons
| 👍 The Good | 👎 The Bad |
| High Power (4kW): The two big burners are beastly; perfect for Indian Kadhai cooking. | Enamel Supports: Lacks the rugged stability of Cast Iron supports found in rivals. |
| Standard Cut-Out: Upgrade to a big 75cm hob without cutting your granite. | 6mm Glass: Thinner than the 8mm industry standard (though high quality). |
| German Safety: FFSD response time is faster and more reliable than budget brands. | Price: At ₹24k, you pay a premium for the brand name vs. specs. |
| Efficiency: Aluminium burners waste less heat energy than brass. | AC Ignition: Requires a plug point; won’t spark during a power cut (unlike battery ones). |
Expert Verdict: Who Should Buy This?
Buy the Bosch PNI7B6B10I if:
- You are replacing an old hob: The ability to fit a 75cm surface into a 60cm hole is a lifesaver for renovation projects.
- You prioritize speed: The 4kW aluminium burners are noticeably faster at boiling and heating than standard brass equivalents.
- You want easy cleaning: The enameled supports and lower profile glass are easier to wipe down than heavy cast-iron setups.
Skip it if:
- You are a “Brass Purist”: If you believe weight = quality, the lightweight aluminium burners might feel “cheap” to you, despite their high performance.
- You use round-bottom woks often: The enameled supports can be slippery for round-bottom vessels without an additional wok adapter.
Here is a curated comparison table of the best market alternatives to the Bosch PNI7B6B10I.
These options target the specific “pain points” of the Bosch model: Price (these are cheaper) and Burner Material (these use Brass, which many Indian buyers prefer over Bosch’s Aluminium).
Best Alternatives to Bosch Series 6 PNI7B6B10I
| Category | Model | Approx. Price | Burner Material | Safety (FFD)? | Why pick this over Bosch? |
| Best Overall Alternative | Elica Flexi 491 Lotus | ₹19,299 | Heavy Brass | No | It uses heavy Brass Burners (Indian favorite) and fits the same cut-out, saving you ~₹5,000. |
| Best “Safety” Rival | Faber Bella HT 904 | ₹18,400 | Brass | Yes (FFSD) | The only rival under ₹20k that matches Bosch’s Flame Failure Safety but uses Brass burners. |
| Best Budget Friendly | Glen 1074 SQ | ₹14,990 | Forged Brass | No | Incredible value. You get Forged Brass (5x stronger than casting) for ₹10k less than Bosch. |
| Best for “Rough Use” | Hindware Laura 4B | ₹12,000 | Cast Iron | No | Simple, rugged, and uses heavy Cast Iron pan supports which are less slippery than Bosch’s enamel. |
Quick Buying Advice:
- Choose the Faber Bella HT 904 if: You absolutely want the Safety Sensor (FFSD) that Bosch has, but you refuse to pay ₹24k. This is the closest 1:1 match in features.
- Choose the Glen 1074 SQ if: You want Durability. Its “Forged Brass” burners are virtually indestructible and carry a 5-year warranty, unlike Bosch’s standard 2-year term.
- Stick with Bosch if: You want Speed. The Aluminium burners heat up faster than all the brass options above, and the German build quality on the valves is unmatched.
People Also Ask (FAQ)
1. Are Aluminium burners good for Indian cooking?
Yes. While Brass is traditional, Bosch’s “True AL 2D” burners offer higher thermal conductivity, meaning they heat up faster and respond quicker to knob adjustments. They are corrosion-resistant and durable.
2. What is the cut-out size for Bosch PNI7B6B10I?
The required niche size is 560 mm (Width) x 480-492 mm (Depth). This is the standard size for most 4-burner hobs, despite the Bosch having a wider 75cm glass top.
3. Does this hob work without electricity?
The gas flow works without electricity, but the Auto-Ignition requires a standard 220V power connection. In case of a power cut, you will need to use a lighter or matchstick.
4. Can I use this with Piped Gas (PNG)?
The hob comes pre-set for LPG (Cylinders). However, the box typically includes a Nozzle Set for Natural Gas (PNG). You must have a certified technician change these nozzles to avoid yellow flames and soot.
