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.

Turn that around for a minute - and put the tank heater in the place
of the tankless, and North America in place of Europe innyour
arguement.

The tank heater has been in use twice as long in North America as the
tankless has been in Europe

There are TWO reasons why the tankless are still expensive to buy and
install:
1) They are relatively new and unknown here, with not much demand for
them yet
2) They are going against what has been the norm during the 50+ years.
Change is slow
I should also mention that there is resistance from the plumbing
establishment, who are being challenged in their "control" zones.

The plumbers should be laughing all the way to the bank. Maintenance
costs are AWFULL.

Point of use water heaters are a different story - THEY actually make
sense.
