Well rich you really show your stupidity and ignorance on tankless
units. Swindlers like Bosch . Wake the F up. Bosch is a company that
will be around longer than you. Bosch is Germanys, GE, they are a very
large Co . into alot of things .Your car probably has Bosch fuel
injection parts in it.

You say tankless are " Necessarily Less efficient " Boy you really
have to read before you make stupid statements. 83 - 84 % Same as
regular tanks..

You Say The Controls consume power Haa Haa what a maroon you are . Mine
uses 2 D cells , No line voltage Nada. and they are 2.3 yrs old .
Bosch also has a unit with a mini Hydro turbine, No batteries, No line
power.
And your statement of life of the electronics being 10 yrs , More of
your stupid Unfounded gibberish.

Efficiency , well you are a real bozo. But dont beleive my claims of
75 % savings over electric tank, and dont look for others that save You
better stay in your cave.
