Now, this guy sells anodes'n'**** for tanks, but I found his take
level-headed.
The raw thermodynamics of tankless -- esp. gas tankless -- puts one
big strike against tankless from the gitgo.

Funny how tankless heaters have been around for more than 50 years in
Europe and are the primary mode of providing hot water to households
One has to wonder why something that has had 50+ years of daily usage in
a large parts of the world would allegedly be so far back technically as
the author claims.

Do you mean tankless for *central* water heating in Europe? I do recall
some people having what was called a "Geyser" (trade name?) over the
kitchen sink when I was a child in the UK, but I don't know whether they
had any other hot-water supply for other rooms.

The only water heaters my family ever had were associated with an
always-burning solid-fuel stove (an "Aga") or later a gas-fired boiler
for central heating and hot-water supply, with an electric element in
the storage tank for use in the summer.

I've noticed in pictures, a water heater inside the bathroom showers of
places in Europe. It appeared to be an electric unit right above the
shower head. ^_^

TDD

that's generally the hold house/apt water heater. time to get to the
shower head is minimal, but can take longer to get elsewhere in the
house. since these are retrofitted to very old places, that's frequently
one of the only places it can go.
Many of them are POU heaters - "point of use" - they do not supply
hot water anywhere else.

Quite often a small tank or tankless POU under the sink in the kitchen
too. MOST hold about a gallon of heated water in reserve
