customers that purchase a PV system from us and want SDHW as well. We want to
recommend a tankless heater where it makes sense (very old gas hot water heater

storage tank, new construction, etc.).</span></font></p>

style='font-size:12.0pt;color:black'>I went to a seminar on the subject a few
years ago and one of the key issues was choosing a tankless heater that “modulates
on input water temperature”. The only one I was aware of at the time was a
small Bosch system with ½ Cu lines. Are there big fellows that “modulates
on input water temperature” and could someone recommend one? </span></font></p>
