Well, if you use a heat-pump, it will be more efficient than a simple heate=

Here almost all households have electric kettles, I'm surprised to learn th=
at
those are not common in other countries, as they are *very* cheap (from
US$10 up to about US$200, depending on brand, thermal insulation and
capacity), so nobody uses old kitchen kettles.

Standard is 1.5 to 2.0 litters and 10A, so 2.2kW. You can boil a litter of
water in about 3 to 5 minutes.

Have fun,
