Hi KayTeg1,
There are "on demand" 120 volt electric heaters intended to be installed at the tap. I think they might be used in series with the existing water tank to extend the length of a shower.

This is whirpool heater, that works with big water flow only.
Having European roots I am familiar with using electricity for heating.
Small 2 bdrm condo has 5 kw WH under kitchen sink and 7-9 kW WH in the bathroom.
Add room heaters, coffee makers and other stuff and the condo ends with 70 kW electric panel.
Not something you can easily do in USA, although they do that in Canada.
Still to save customers from sticker shock, they spread winter heating payments for 12 months.
One day I will take my time to make recovery time, but for now we don't plan on 2 long showers in the same morning.
Still electric element, being at the bottom of the tank gives you more heated volume than gas burner, so we are doing 2 quick showers back to back.
