BOSCH PVS611B16E Series 4

What do I need for recirculation?
You need a recirculation kit, which includes carbon filters and possibly a deflector.

Can the hob be connected for recirculation?
Yes, most modern hobs with integrated extraction support recirculation mode.

Is the extraction efficiency sufficient? Does the extraction work well?
Yes, thanks to its proximity to the source of the vapors, extraction is very effective even at lower power settings.

Is an extractor directly in the hob better, or is it better behind/above the hob?
A hob extractor saves overhead space, while a classic hood tends to run slightly quieter.

Does the extractor have a notification for the need to clean/replace filters?
Most models come with a saturation indicator for both the grease and carbon filters.

How long can the duct connection be for external extraction?
A length of up to 5–7 meters with as few bends as possible is recommended to keep performance up.

Is a non-return valve included in the equipment?
It depends on the model — versions designed for external ducting often include a non-return valve or ductwork in the package.

What happens if liquid spills on the hob and flows into the extractor?
Extractors have a liquid collection tray that can be easily removed and cleaned.

Is it possible to install an oven under a hob with extraction?
Yes, but it requires careful space planning for the ductwork and cooling.

Why isn't the ductwork included in the package?
Because every installation is unique and requires a different length and type of connecting components.

What is the difference between flexi, combi zone, and round inductors?
Round zones have a fixed size. A combi zone bridges two separate zones into one larger area. A flexi zone, on the other hand, adapts to the shape and size of the cookware anywhere on the surface.

Can I connect the hob to 400V?
Yes, most induction hobs can be connected to 400V (two phases), which is actually recommended for reaching full power.

Why can't I connect a hob with a power input of 4.6 kW to two phases?
A 4.6 kW power input is designed to run on a single, stronger phase. Splitting the load across two phases usually requires a higher total power rating, around 7 kW.

On your website, you state Voltage 220-240 V, can the hob be connected to a multi-phase connection?
Yes, the 220-240V figure refers to the voltage per phase. The hob can typically be connected to two phases (400V) as well.

Which hobs are designed for flush installation?
These are frameless models with polished edges, listed in the range as suitable for flush-mount installation.

The hob is noisy, it clicks loudly.
The clicking comes from switching relays or the power management function. It's a normal operating characteristic of induction technology, not a fault.

Is it possible to turn off the sound signals on the hob?
Yes, on Bosch and Siemens models this can be done in the "Basic Settings" menu (C2). Confirmation tones can be muted, but warning signals stay active regardless.

What is the smallest diameter of cookware that will work on an induction hob?
The minimum diameter depends on the size of the zone, and typically falls somewhere between 9 and 12 cm.
