Time for a little education.
Check the link to see what piezoelectricity is.

Then rest assured that the ignition spark does not need any external
electricity.
It is all self contained

And how do you apply the pressure to ignite the water heater? I am guessing
that it is NOT piezo, but simply an electronic ignition, which will not
ignite unless there is electricity. Otherwise it has an extra feature that
allows you to ignite the pilot without a match or lighter. One thing to
remember is that the pilot also keeps the water hot and prevents you from
having to ignite the burner to reheat the water as it gets cold. I have our
water heater set at the temp that the pilot holds the water at and have
sufficient hot water except when 2 of us are taking long showers at the same
time. I really need to get a bigger tank with two of us working dirty jobs
and getting home at the same time : 0

Hello:

Will be going for a new hot water heater soon.
For a residence. The typical cylindrical type independent of the
furnace.

Regarding those new gas fired water heaters with the Piezo ignition:

Do they work in a house power outage, such as in a storm ?
We lose power often, and would sure like to have, at least, hot water.

Thanks,
B.
