First, PVC is not rated for hot water. If using plastic, go with CPVC or PEX. I would still use copper within 18" of the heater. Second, these heaters usually dont deliver enough hot water to satisfy peak demands. I would suggest a Rannai gas tankless. Its more expensive but it works, and will save you alot of money. Electric tankless heaters just dont deliver the GPM of water that gas units can. Considering your situation, the electric model would be a good choice.
