Water pipes must be designed for hot water service (ex. copper, cpvc, or Pex A).
Pipes should be installed in a 4” water tight pipe or some other type of insulating
means to prevent heat loss from heater to heating system. Use only copper,
brass, or stainless steel fittings. Do not use galvanized or black iron.
