Inner water and electricity lines are designed to run separately so as to avoid leakage or harm of scale build up. Approval by ETL and qualifies for UL, you can expect outstanding performance for years to come.
  • 【CONVENIENT USE】The tankless water heater comes with digital display & touch control panel so temp setting is easy job.
