Also some newer ones have temp sensors so you can keep a thing at the exact temp you need.
I swear by induction cooking (for both soapmaking and food) for this reason - precise temperature control, even low temperatures that aren’t even possible to get on a gas stove.
- Setting the heater to exactly 40C means you can melt chocolate reliably, without the hassle of a bain marie
- At 60C you can combine cetostearyl alcohol and vegetable oil for moisturizer without boiling off your glycerine
- At 80C you can cook soap to trace without overcooking it and making it lumpy
- At 100C you can evaporate moisture and reduce a sauce with minimal effect on other ingredients
- At 100-160C you can cook a sugar syrup to a precisely desired level of concentration (as the boiling point goes up as the concentration increases) for making different types of candy

For comparison, in Australia, gas and induction are at price parity (a budget 4-hotplate setup costs about $200-300 either way). You can buy a single-plate induction cooker for $50 that plugs into the wall and has a temperature configurable from 60-200 C.

PS: Also, electricity is cheaper than gas in Australia, because we have so much rooftop solar, electricity is soon going to be free during the midday peak.
