Gas hob / cooker

Needs power

Cooks on a gas flame. Responds instantly and keeps working when the power is out, which is the one resilience argument in its favour; against it, burning gas indoors puts combustion products into the room, so it wants real ventilation above it.

One of 9 ways to meet Cooking energy supply. Build 2/9, Upkeep 5/9, Efficiency not rated. Cost, carbon and footprint below are rated against those 9, not in absolute terms.

Regulation (FR example)
Gas appliances must be installed and commissioned by a qualified fitter, and a French installation is subject to periodic inspection.

What your site needs

A gas supply or room for a bottle, and extraction above the hob: this is the one appliance in the house that burns fuel in the room people are standing in

What this page does not tell you

No sizing or quantities: how much a technique yields, and how much a household needs, both depend on the build and the people, so the catalogue compares options rather than dimensioning them. It carries no bill of materials and no build sequence, and it is written for an oceanic, clay-soil climate (Normandy, France). Regulatory notes are indicative and need confirming locally.
