I have a tank-less hot water system in my house, also on untreated well water, now 22 years old. we had a similar problem with lose of hot water while taking a shower. Always seemed to happen while my teenaged daughter was taking a shower. HAHA.

Had a plumber come out and he replaced a mixing valve problem solved. Seems that the due to the untreated water, the mixing value gets corroded overtime. Now 4 showers in the morning and plenty of hot water.

I think it cost was about $100.00 parts and labor if I recall.
