That seems like a stupid ban. Heat pump water heaters are impossible to install in many smaller dwellings, even if we're ignoring the need for large storage tanks.

The only problem with resistance heaters is the large current draw to heat water for bathing. Central heating can be done at lower temperatures (as is the case with heat pumps), but bathing cannot.

There are some resistance heaters with built in (electrochemical) batteries aimed at reducing peak current, but I'm assuming the ban would affect those as well...
