Default Tankless water heater maintaince

So I got my tankless water heater today.
And figured I will break from tradition and read the manual before I install it.
It looks like in the manual they highly recommend adding provisions to hook up an external pump so that vinegar or citric acid solution can be circulated through the heat exchanger to remove scale build up.
The manual makes this maintaince sound pretty important.

This isn't a problem for me I have extra brand new 3/4 inch valves I bought from the scrap yard for maybe $1 each and I have a pump that can circulate the recommend volume (2 to 4 gpm).

The tankless heaters are not as maintaince free as I thought.

If you want low to no maintenance get an electric tank heater and put a magnesium anode in it.
