Aqua-Hot gen 1 D4 E Heater

is a heating system that produces warm air and warm water

The heater can be used while driving.
The diesel burner is Aqua-Hot's primary and most efficient heat source.
The electric element is the secondary heat of the Aqua-Hot
These temperatures can be activated by turning them on in the fuel source (GAS/EL/MIX) selection LCD.
4 modes: OFF, ECO, HOT and BOOST.
In ECO mode, the heating mode brings the tank temperature to 104°F.
In HOT mode, the heating mode raises the tank temperature to 140°F.
In BOOST mode, the heater prioritizes water heating for 40 minutes or until the water temperature reaches 60°C (140°F).
The system uses temperature readings from the RV internal thermistor.
In OFF mode, the burner is off and shuts down, providing no heat to the interior or water.


There are three heating options:
• Diesel mode: the heater automatically adjusts power according to temperatures.

• Hybrid mode: the system controls the use of electric and diesel heating based on the system's power demand.

• A diesel burner can be used with an electric element to heat and produce hot water.
