LPG to induction: switching a restaurant kitchen

You can move a restaurant kitchen from LPG to induction without stopping service by doing it in phases. Confirm the electrical load first, then replace one station at a time during quiet hours, starting with boiling and gravy work. Keep gas running for the remaining stations until each new induction unit is proven in service.

Start with a clear reason and a clear scope

Kitchens move to induction for different reasons: LPG availability, cylinder handling, kitchen heat, or a plan to reduce fuel waste. The reason shapes the scope. Some kitchens move everything. Many keep gas for wok and flame work and move the rest. Decide this at the start, because it changes the electrical work and the order of the phases.

If you have not yet decided which stations suit induction, read our balanced guide to choosing induction or gas for Indian cooking first.

Step 1: check the electrical supply

This is the step that most often delays a switch. Commercial induction units draw heavy current, usually on three phase supply. Before ordering equipment, get a licensed electrician to check:

• The sanctioned load on the electricity connection and whether it needs to be increased.
• The capacity of the main incoming cable and the distribution board.
• Space for dedicated circuits with suitable protection for each induction unit.
• Earthing quality, since induction electronics are sensitive to poor earthing.

A load increase can take time to approve, so apply early. Running new cables to the cooking line can usually be done at night or on the weekly off day.

Step 2: plan the order of stations

Move the stations that are easiest to convert and least risky to service first. A typical order looks like this.

Phase one: boiling and holding

Stock pots, rice and noodle boiling, and bain marie style holding are simple to move. They use flat bottomed vessels, run for long periods and benefit from steady heat.

Phase two: gravies and sauces

Gravy bases, dals and sauces move next. Chefs need a few days to learn the power settings, because induction responds faster than a flame.

Phase three: frying and tempering

Shallow frying and tempering in flat pans can follow. Deep frying may move to electric fryers rather than induction tops.

Decide last on wok and flame work

Wok cooking, rotis finished on flame and charring are the hardest to move. Some kitchens keep a small gas section for these permanently.

Step 3: install during quiet hours

Fabricate the new induction units and their stands off site so that installation on site is short. A good sequence is to remove one gas unit after the last service, install and connect the induction unit overnight, test it, and use it the next day with the gas unit still available nearby if possible. Because Steelkraft fabricates in-house and uses its own installation team, units can be built to fit the existing line and installed in short windows.

Step 4: cookware and training

Induction needs flat bottomed magnetic cookware. Check every vessel the station uses, including the large ones that only come out for banquets. Budget for replacements before the switch, not after.

Give staff hands on time before a busy service. Show them how power levels compare to flame sizes, how quickly a pan heats and how to avoid running empty pans at high power. Most chefs adapt within a week once they trust the equipment.

Step 5: deal with the gas lines safely

When a gas station is removed, the line feeding it must be isolated and capped properly. If gas is removed entirely, the manifold, regulators and cylinders should be decommissioned by a qualified gas installer. Do not leave live, unused gas points in the kitchen.

Review the exhaust

Induction puts less heat into the room, but grease and steam still need to be captured. The existing hood usually stays, though filters and fan speed may be adjusted. See our commercial exhaust systems if the hood needs to be resized or replaced.

Common mistakes during a switch

The most common mistake is ordering induction equipment before the electrical supply is confirmed. Units arrive, sit in storage and the kitchen waits weeks for a load increase. The second is moving the hardest stations first. If the wok or tawa station is changed before chefs have learned induction on simpler work, confidence drops and the project stalls.

Another mistake is forgetting the large vessels that only come out for banquets or festival menus. They are often round bottomed or aluminium and will not work on induction. Check every vessel, not just the ones used daily. Finally, some kitchens remove gas completely and then discover they need a backup during power cuts. Decide on backup before the last gas unit leaves.

Measuring the result

Keep simple records before and after each phase: LPG consumption, electricity units, kitchen temperature during peak service and any complaints from chefs about speed or quality. These numbers show whether the switch is working and help decide whether to move the remaining stations. They also give you real data instead of assumptions when you plan the next outlet.

Frequently asked questions

How long does a phased switch to induction take?

It depends mainly on the electrical work and any load approval. Once the supply is ready, individual stations can often be changed overnight, so the kitchen keeps working throughout.

Should I remove all gas from the kitchen?

Not always. Many restaurants keep a small gas section for wok cooking and flame finishing. Keeping two fuels also gives the kitchen a backup if one supply is interrupted.

Will my existing exhaust hood still work after the switch?

Usually yes, since grease and steam still need to be removed. The fan speed and filters may need adjusting, and a review is worth doing once the new line is running.
