Gas or Electric Cooking Ranges, What Suits Your Kitchen

Choosing between gas and electric for a new cook line is not a matter of taste, it decides how the rest of the kitchen gets built around it. The decision affects running costs, how hot the kitchen gets to work in, how much extraction the canopy needs to shift, how quickly the equipment responds when a chef needs it to, and how much power the site can actually bring in.

Get it right and the kitchen runs cooler, the extraction system is sized sensibly, and the electrician or gas engineer only has to visit once. Get it wrong and you are living with the compromise for the next fifteen years, whether that is an undersized supply, an oversized extraction run, or a station nobody wants to stand next to on a hot afternoon.

Running costs and heat in the kitchen

Gas burns hot and a good deal of that heat radiates outward rather than into the pan, which is why a gas-heavy line pushes ambient kitchen temperature up over a service. Electric and induction put more of the energy directly into the food, so the kitchen around the cook line tends to stay cooler, which matters for staff comfort and for anything stored nearby that is heat sensitive.

A gas chargrill is a good example of where this trade-off is most obvious. The Blue Seal G592-B 300mm Gas Chargrill gives the direct flame contact and char that a steak or burger section wants, but it is also the station that throws the most radiant heat back at the chef standing in front of it, and it needs a gas supply and proper extraction to work safely.

Extraction load and the interlock question

Every gas appliance under a canopy adds to the extraction rate the system has to achieve, and current practice on any commercial gas line is to fit a gas interlock system that cuts the gas supply if the extraction fan fails or airflow drops below the set point. That is a sensible safeguard, but it is also another piece of kit to install, commission and maintain, and only a Gas Safe registered engineer can legally work on the commercial gas pipework and appliances involved.

Induction removes a good deal of this from the equation because there is no open flame and no combustion products to extract. A single or twin ring induction cooktop still needs some ventilation for residual heat and steam, but the extraction burden is a fraction of what a comparable gas burner or griddle would demand. The Blue Seal Evolution IN511R3-LS 450mm Single Zone Induction Cooktop suits a compact line or a satellite station where a single point of high-output cooking is needed without adding to the main canopy's workload, while the Blue Seal Evolution IN512R3-LS 450mm Twin-Zone Induction Cooktop & Stand gives two independent zones in the same footprint, useful where a section needs to run a sauce and a sear at the same time without competing for space on a shared gas ring.

Controllability, from flame to induction to pan tilt

Gas gives instant visual feedback and chefs who trained on it tend to trust it instinctively, but the heat is harder to control precisely because the flame itself does not change temperature, only the amount of it reaching the pan. Induction responds within a second or two of the dial being turned, and because the heat is generated in the pan base rather than around it, there is very little residual heat once the power is cut, which also helps with the running cost picture above.

Where a kitchen needs one appliance to do the work of a bratt pan, a kettle and a griddle, an electric cooking centre changes the layout question altogether. The Rational iVario 2-XS Dual-Pan Electric Cooking Centre is built for this kind of consolidation, with two independently controlled pans that can braise, boil, fry or hold at a set temperature, which suits an operation trying to reduce the number of separate gas appliances on the line rather than add to them.

Supply capacity, three-phase and the practicalities of gas

Electric and induction cooking lines draw their power from the building's electrical supply rather than a gas main, and a run of induction cooktops or an electric cooking centre will typically need a three-phase supply and enough spare capacity in the incoming board to carry it. This is worth checking before equipment is chosen, not after, because upgrading a site's electrical supply is a bigger job than most people expect.

Larger or bench-mounted induction equipment makes this point clearly. The Blue Seal Evolution IN514R5-B 900mm Induction Cooktop Bench Model is a wider, higher-output unit intended for a busier line, and equipment of this scale needs the electrical supply confirmed at design stage. Points worth checking before specification include:

• Whether the site has a three-phase supply, and how much spare capacity is left on it
• Whether the gas main and meter can support an additional appliance such as a chargrill
• Whether the extraction canopy and any gas interlock will need upgrading or recommissioning
• Who is available locally to service the equipment, a Gas Safe registered engineer for gas or a qualified electrician for induction and electric

How Advantage Catering Equipment can help

We design cook lines around what a site can actually supply, not just what looks good on a spec sheet, and we work with gas and electric equipment from manufacturers including Blue Seal, Rational, Lincat and Falcon. Whether that means checking three-phase capacity before you commit to induction, sizing extraction and interlock arrangements for a gas line, or mixing the two to get the best of both, we can survey the kitchen and advise before anything is ordered.
