    Electric tankless tends to be quite rare due to needing a lot more wattage than most household circuits can provide

      Depends on the size of the house and the water needs.

      I installed a totally electric tankless water heater made by a reputable manufacturer in my home on my own 11 years ago and just wired in a new 40 amp 220V breaker into the panel to support it.

      It was actually very easy and plenty adequate for the water usage in a 2 bed / 1 bath home (including kitchen usage) for a 2 adult and 2 child household.

      For more bathrooms or occupants it might be more difficult, expensive, or rare but in my case I did the whole job myself for under $350 including everything… But again, it was 11 years ago so I’d expect prices to be a bit higher

        FYI that’s almost 9000 watts of power to supply that thing, which is about 9 microwaves or 3 electric ovens worth.

          That’s not constant throughput though. That’s absolute peak possibilities.

          Editing to add:. FWIW, it also didn’t increase the monthly average electrical usage at all… In fact, I believe I had a small reduction in the average… It was replacing a significantly older traditional 30 gallon electric water heater.
