What about the voltage?

musicteacherJune 21, 2014

I am replacing a cooktop - has to be electric- and am worried that Induction is really out of my price range There are obvious benefits but am I ruining my kitchen by NOT going there? I have heard comments about needing to rewire for induction. Would that be likely in a 30 year old house? Thank for your advice

You'll need a dedicated 240 volt run but the amperage depends on the cook top. Rule of thumb seems to be 40 amps for most and fifty for the bigger ones.

It's not the voltage that matters in this situation - since you have an electric cooktop already, you should have a 240 volt circuit. Just to confirm, this is a cooktop only with the oven separate, not a range, correct? If so there is a good chance you only have a 30 amp circuit which will limit your options for induction. Head down to the breaker panel to check out your situation and post back what you find!

"Ruining" is a tad strong. There is still debate here about whether induction or gas is the best. However, if the alternative is electric coil, whether exposed coil or buried under-glass coil, then induction is certainly superior in just about every way but cost, and even that might be partially refunded by much higher efficiency than coil, and significantly easier clean up. The cooking dynamics are much like gas, so one gains the control capabilities of gas with improved safety.

My kitchen was 20 years old and had a glasstop electric cooktop, but it was on a 40-amp circuit. We replaced it with induction and are thrilled with it. Prices are coming down. It will change your life!
