Hi Arlis,
I have no doubt that you have seen many cases where the units under-performed or had problems, but there has to be some common factors as to why they don’t work in cases, and why they work flawlessly for folks like SkyDancer and myself.
Perhaps the layout of the house (multi-story), or the type of plumbing (Pex vs. Copper), consistent water pressure issues or some combination of factors.
I’ll probably never know but that’s the darn electronic engineer in me ... always wanting the details. :)
You are probably correct, but while I hear in the industry all the negatives of the electrical units, I have never heard the specifics so I cannot analyze let alone comment on what the problems are.
I do know I almost never hear of problems with the gas units.
