Reply #37: Few more questions....

[CardInAustin]

Thanks for the info....a few more questions though:

1) Can my current hot water heater (maybe 10-15 years old) be retrofitted for solar?
2) If I use tankless, I assume that would take the place of the gas heater on the tank (figuratively, not literally)
3) Does the tankless check the temperature of the water coming in to see if it needs to be heated or not? How can this be accomplished so quickly at the point of delivery (just under the sink)
4) If I were to install such a system, I would only need to install tankless systems at each of the sinks....right? I would not need the single large tankless system that is capable of providing 2 showers worth of hot water. Correct??

Thanks!!!!
