Look on the leading black pipe. Black pipe (galvanized steel with another
component) ultimately works like a di-electric conductor when in contact
with copper, hence a "device" that bleeds electricity off the pipes and to
ground. I have one that preceeds my water heater, which is prior to my
boiler, and it needs either cleaning or changing every few years. And it's
because there's electricity generated by the difference in the metals. It's
not just in this circumstance that one finds a necessity for an anode. Like
I said, it's required on any outboard or inboard/outboard boat motor in salt
water, too.

Makes one wonder if, since there's enough difference between two pieces of
metal to generate an electrical difference, then perhaps we have a method of
free power right there, although it would be exceedingly small. Maybe with
a million miles of copper and some black pipe here and there we could
generate enough electricity for a house?

Gas has black pipe running (a electric path to copper waterpipe), but

it doesn't have to be. Technically you could change out the gas piping
for
a flexible plastic and end the problem once and for all (like using
optical
to end ground hums). Personally, I just have my gas water heater hooked
up
to the water pipe and change the anode connection every couple of years.
The last water heater lasted 18 years. This one's into it's sixth year
and
clean as a whistle.


What's the anode connection on a gas water heater ?

I suspect our UK water heaters are a bit different.
