30yo Brazilian here. I nor anyone I know have heard of issues with electric shower headers. Electricity in Brazil is highly available and relatively cheap. I actually think they're amazing and I would pick it over any gas shower out there, they heat up pretty much instantly and some models even offer high precision temperature control of 1 degree Celsius.

FWIW "heats up instantly" and "has 1 degree temperature control" also describes modern gas heaters.

I'm hoping you're right but I have yet to see a gas heater that actually heats up the water that cooled down in the pipes since the last usage so that you actually get warm water instantly.

I mean, it may be a couple seconds (like 5, not 30+), but ~every modern house in Japan has a heater like that.

They heat up instantly, but I usually have to choose between high pressure and heat. Only when turned down to low pressure does the heat work well (you can subtlety hear it click on at low pressure). But it depends in the specific model and usually not bad. (In Guatemala) And have been zapped plenty of times as others described.
