How these alternatives compare
Orbek 60,000 BTU 12V RV Tankless Water Heater
The Orbek 60,000 BTU model uses propane and runs on 12V DC, matching the APUS power requirements. It is slightly smaller at 12.7 inches square, which helps in tight compartments.

Camplux 2.64 GPM Portable Propane Water Heater
