Gas vs Induction in a Van: Which One Actually Makes Sense?

Here's what I didn't expect when I tested induction full-time last summer in Spain: the inverter efficiency penalty is real. At 1,500W through a 2,000W inverter, you lose about 10-12% to heat — so your battery actually sees closer to 1,700W of draw. In winter with reduced solar, I burned through my 200Ah bank in two days trying to cook exclusively on induction. Went back to the gas stove by day three. The safety argument for ditching gas is valid — no open flame, no CO risk, no leak worries — but the electrical cost is steep unless you've got 300Ah+ and serious solar. One thing gas can't do though: a good induction plate simmers at exactly 60°C for hours without supervision. Perfect for slow-cooking a stew while you drive.

The Real Energy Cost Per Meal: Gas vs Induction#

I tracked every meal for a month on each method. Gas (propane): boiling 1L of water takes about 4 minutes on a decent two-burner stove. A full meal (pasta + sauce) uses roughly 150g of propane — about $0.45 at current prices. Frying, simmering, and quick meals average $0.25-0.60 per cooking session. Monthly gas cost for cooking two meals a day: $15-35. Induction: boiling 1L takes 5-6 minutes at 800W (about 80Wh with a lid). A full meal uses 200-400Wh. At my solar production cost (amortized system cost), that's effectively $0. But if I were buying grid power at a campground, 400Wh at $0.30/kWh equals $0.12 per meal. Induction wins on running cost, gas wins on energy independence in bad weather. The honest answer: both cost almost nothing per meal. The real difference is in the system requirements.

Ventilation and Safety: The Gas Problem Nobody Wants to Discuss#

Propane combustion produces CO2 and water vapor. In a sealed van, a gas stove raises CO2 to uncomfortable levels within 15 minutes — I measured 2,500 ppm in my Sprinter with one burner running and no windows open (outdoor baseline: 400 ppm). Above 1,000 ppm you get drowsy. Above 5,000 ppm it becomes dangerous. Carbon monoxide is the bigger risk: an improperly adjusted burner or a stove with blocked ports can produce CO at lethal concentrations in a small van. I installed a dual CO/CO2 monitor ($40) next to the stove and crack a window every time I cook on gas. A MaxxFan on low also works. Induction produces zero combustion byproducts — you can cook with every window sealed in a rainstorm with zero air quality concerns. For winter vanlife, this alone tips the scale toward induction if your battery can handle it.

My Setup: Why I Run Both#

After testing each method exclusively, I settled on a dual setup. A two-burner propane stove (Camp Chef Everest, $100) for heavy cooking days, winter use, and when the battery is below 50%. A single-burner induction plate (Duxtop 1800W with adjustable power settings, $70) for summer cooking, simmering, and when I'm parked with good solar. The propane stove connects to a standard 1lb canister or a refillable 5lb tank with a hose adapter. The induction plate runs through my 2000W Giandel inverter on 50mm² cables (185A draw — 10mm² will melt). Total weight for both: 6kg. Total cost: $170. Having both means I never compromise — gas when power is tight, induction when solar is plentiful. The induction plate stores flat under the bed when not in use, and the gas stove folds into a compact unit that fits in the kitchen cabinet. Flexibility beats ideology every time in vanlife.
