Availability of Water Heater That Does Not Run on 12V DC Power
Published 03/31/2023 >
Question:
I have a park model trailer that does not have 12v DC power. I need to replace the original Atwood GC10A2 water heater. Is there a replacement electronic ignition RV water heater, tank or tankless, that does not require 12v power?

The only water heater we carry that doesn't run on 12V DC power is the Excel RV Tankless Water Heater # EX93FR.
This has an electronic ignition and actually runs on 2 D-sized batteries. A little unconventional but it still works and is able to produce 1.6 gallons of hot water per minute.
