Not with gas units. They have a spark igniter - just like your gas

The flow of the water generates the spark? (I'm envisioning someone having to go
press the red button on thhe unit late at night!)

Don't hold my feet to the fire, but Bosch TWH indicates the spark
takes place after the hot water is requested from inside the house.

..hydro-generator..?

BTW TWHs can last many years and is easily serviced by the home owner.

tankless have high tech electronics and controls, and may need perodic
sediment removal. its best to get a tankless where local experienced
service is available.

from the time water is first drawn, tankless burners turn on and
heated water finally reaches the fixture theres a delay, and waste of
water

Bob (Goggle Post),

Have you been up close to a tankless system? I understand if not.

You sell yourself as a "hater" of tankless. Not once have you typed
the positive.OR even a negative. Not to point this out but tankless
can be a perfect move/solution.
