Choosing water heating methods (solar, desup, etc), and combining them
Q1: Are the two methods combined likely to handle a the hot water needs of a 5-person family? Or would you still have a regular water heater to pick up the slack?
Of the three systems, which pair would you choose? Or would you deploy all three? Here are the three:
1. Solar water heater
3. Tankless natural gas or electric water heater
Region: Tucson, AZ and Las Vegas, NV (very similar, nearly equivalent climates)
Thanks for your help.
