The rockstar plumber is imagining things are cleaner. He had to readjust the temp hotter to compensate for the tanks gradual decrease in temp as t runs out of hot. Bottom line is the rockstar had a tank heater that was too small for the demand.

I am so amazed at the wisdom

Please do, since you know so much about it.

Oh wait, I forgot, you hate tankless. Maybe we can get some solar mixed into this one!

That would apply for that last 5 minutes as you start to run out of water, not the first 15.

I think we are talking about two different things. All's I was saying is that heat exchangers and servo valves like soft water. As for the rest of what you described, that's not how I explain it to customers

Ion exchange resin remove ions from the water via a single displacement reaction. Calcium scale forming on a heat exchanger is due to ions with a negative solubility constant crashing out of solution and forming crystals on seed surfaces. They are in no way the same. In fact, the fact was designed to prevent the second.

This thread just turned into a tankless water heater cult ritual or something........

The only similarity between the two is that they both collect calcium.

But they do so at different rates and by totally different chemical reactions. Further, A tankless heater will precipitate the same amount of calcium carbonate out as a tanked unit.
