Frequently Asked Questions
Can space heating and hot water be used simultaneously?
Yes. According to the original product documentation, space heating and hot water can operate simultaneously, or either function can be used independently as needed.
How do I choose between the diesel and gasoline versions?
Choose the appropriate version based primarily on the vehicle's or vessel's existing fuel system. Both models come standard with a mains power function. The specific operating temperature, accessories, and control configuration should be confirmed before ordering.
Does it support both 110V and 220V mains power?
It supports 110V/220V mains power, with a mains heating output of 900W or 1800W. Select the appropriate version based on the actual grid voltage; versions with different voltages must not be connected interchangeably.
Can fuel and mains power be used together?
The product supports a combined fuel and mains power mode. The actual operating combinations, switching logic, and safety restrictions are subject to the control manual for the selected model.
What is the maximum number of warm air outlets that can be connected?
The product delivers warm air through four heating ducts, allowing outlets to be installed in different areas. Duct length, the number of bends, and airflow balancing should be confirmed during installation planning.
What are the water tank capacity and pressure?
The built-in water tank has a capacity of 10L. The maximum system pressure and maximum water pump pressure are both 0.35MPa. Pressure control and safety protection devices should be installed at the water inlet as required.
Can it be used at high altitudes?
Yes. It features an intelligent high-altitude function and can operate at elevations of up to 5,000m. For use in extreme environments, follow the technical documentation for the specific model.
