Liquid and Air Heater Combi -4KW Water Heating & 2KW Air Heating -Combi A

1. Dual Heating Design, One Machine for Two Purposes
The liquid and air combi heating structure supports independent and synchronous operation of water heating and air heating. It delivers 4KW water heating power to provide sufficient domestic hot water for bathing, cleaning and daily use, while 2KW air heating power ensures stable and comfortable cabin heating. It perfectly matches the daily living configuration of RVs, realizing all-round thermal comfort with one device and eliminating the need for purchasing and installing separate warm air heaters and water heating equipment.
2. Triple Fuel Compatibility, Strong Global Market Adaptability
To adapt to diverse fuel supply standards in different overseas regions, the heater supports three mainstream fuel types: diesel, gasoline and liquefied petroleum gas (LPG). Users can switch freely according to local fuel availability and cost, with no restriction on regional fuel resources. The multi-fuel design greatly improves the product’s universality in European, American, Australian and Southeast Asian markets, perfectly fitting global outdoor and mobile living scenarios.
3. Low Fuel Consumption & High Cost Performance
Adopting optimized premixed combustion technology, the overall fuel consumption is controlled at 0.2–0.5L per hour. While maintaining dual high-power heating output, it achieves efficient fuel utilization and low operating cost. Compared with purchasing two independent heating devices, this all-in-one unit greatly reduces equipment procurement cost, installation cost and later maintenance cost, with outstanding comprehensive cost performance for personal use and batch refitting projects.
4. Simplified Installation Structure & High Practicability
The integrated modular structure is optimized for RV internal installation. It features a compact overall layout with reserved standard interfaces, realizing plug-and-play simple installation. The streamlined assembly process saves modification time and labor costs, friendly to individual DIY installation and overseas aftermarket refitting teams. No complicated pipeline layout is required, effectively saving limited internal space of RVs and camper vans.

1. Wide Temperature Adaptation for All-Season Use
The heater supports stable operation in a wide temperature range of -25°C to 40°C. It can cope with severe cold winter environments and high-temperature summer climates, realizing all-season normal use. Whether for low-temperature camping in northern regions or outdoor travel in high-temperature tropical areas, it maintains stable dual heating performance, adapting to complex and changeable global outdoor climates.
2. Stable Dual Output & Comfortable Heating Experience
With mature combustion and heat exchange technology, the unit ensures stable hot water output and uniform cabin warm air circulation. The air heating system avoids dry and hot air, while the water heating system provides constant-temperature hot water supply. It fully meets daily bathing, cleaning and cabin heating needs of RV mobile life, greatly improving the comfort of long-term self-driving travel and outdoor camping.
3. High Safety & Reliable Continuous Operation
Built with multiple safety protection mechanisms such as overheating protection, flameout protection and abnormal fuel supply detection. It can operate stably for a long time during unattended outdoor camping and overnight parking. The high-strength sealed structure avoids fuel leakage and heat loss, ensuring safe and reliable use in closed mobile spaces such as RVs and modified vans.
4. Lightweight Integration & Space-Saving
Compared with traditional split heating systems, the highly integrated design reduces redundant structural parts, featuring small footprint and light overall weight. It will not increase excessive load on the vehicle, nor occupy valuable RV living space. It is perfectly compatible with various types of campers, caravan and modified mobile vehicles, with extremely high scenario adaptability.

1.RV & Camper Van Daily Living: Provides synchronous cabin heating and domestic hot water supply, meeting full-scenario living needs for self-driving travel and long-term outdoor camping.
2. Mobile Modified Vehicles: Suitable for modified vans, mobile office vehicles and field rest vehicles, supporting all-weather comfortable heating and hot water supply.
3.Global Outdoor Travel: Multi-fuel adaptation fits different regional fuel habits, perfectly matching cross-country self-driving tours and global outdoor leisure scenarios.
4.Commercial Refitting Projects: Simple installation, low failure rate and high cost performance, ideal for overseas RV refitting factories and dealer batch procurement.
