Products function
This advanced dual-function heater seamlessly provides domestic hot water and space heating simultaneously, even while your vehicle is in motion. Designed for ultimate versatility, it supports three intelligent energy modes and features anti-freeze protection for year-round reliability.
Key Operational Modes：
Combined Heating Mode (Hot Water + Warm Air)
Simultaneously heats cabin air and domestic water;Ideal for cold weather journeys or multi-demand scenarios;Compatible with all energy modes (Gas/Electric/Hybrid)
Hot Water-Only Mode
Energy-efficient option for showers, kitchen use, and cleaning;Select between 40°C (eco-friendly) or 60°C (high-demand) temperature presets
Smart Energy Management
① Gas Mode (Automatic Power Adjustment)
Self-regulating combustion system optimizes fuel efficiency;
Immediate shutdown upon reaching target temperature
② Electric Mode (Dual-Power Selection)
900W Mode: Ideal for low-capacity campsite power (15A)
1800W Mode: Maximizes heating speed with 30A+ power supply
③ Hybrid Intelligence Mode
Prioritizes electric heating during low-demand phases (e.g., temperature maintenance)
Automatically activates gas assist when electrical capacity is insufficient;Smart transition logic: Electric heating first engages/disengages during power adjustments
Critical Winter Operation Notice
When ambient temperatures drop below 3°C:
⚠️ Mandatory Anti-Freeze Protocol;Fully drain all water tanks and pipes;Run system in dry mode for 5 minutes to purge residual moisture;Store with drainage valves open

Products Feature
LPG (propane) air and water combi heaters for RVs are designed to provide efficient heating and hot water in compact, mobile environments. They are ideal for off-grid adventures, cold climates, or extended travel where space and energy efficiency are critical. Below are their standout features：
Dual Functionality:
- Provides space heating (warm air for the RV interior) and hot water (for showers, sinks, or appliances) in a single unit.
- Eliminates the need for separate heaters and water boilers, saving space and weight.
Compact and Lightweight Design:
- Built for RVs, campervans, or caravans with space constraints.
- Wall-mounted or integrated units to maximize floor space.
LPG (Propane) Fuel Compatibility:
- Runs on propane, a common and portable fuel source for RVs.
- Efficient combustion systems minimize gas consumption (e.g., 100–300g of LPG/hour, depending on output).
Energy Efficiency:
- High-efficiency heat exchangers maximize heat transfer from LPG combustion.
- On-demand heating reduces wasted energy (no standby mode).
Cold Climate Performance:
- Frost protection and freeze-resistant components for winter camping.
- Reliable operation in sub-zero temperatures.
Safety Features:
- Automatic shut-off for low gas pressure, overheating, or flame failure.
- Carbon monoxide (CO) detectors and oxygen depletion sensors (ODS) for indoor safety.
- Ventilation requirements to prevent gas buildup.
Adjustable Output:
- Variable heat settings for air and water to match demand (e.g., low for mild nights, high for extreme cold).
- Thermostatic controls for precise temperature regulation.
Quiet Operation:
- Low-noise fans and burners to avoid disrupting the RV environment.
Easy Installation and Compatibility:
- Designed to integrate with RV plumbing and HVAC systems.
- Compatible with 12V DC or 220-230V AC /115V AC power (for ignition and controls).
Durable Construction:
- Corrosion-resistant materials (e.g., stainless steel) for longevity in humid or salty environments.
Products Application
The cold wind whistles, and the snow-capped mountains in the distance sparkle in the morning light. Your RV is parked quietly, but warmth flows inside the car. Gently turn on the hot water tap, and the warm water awakens your skin; the warm wind spreads silently, and the frost on the RV window quietly melts. At this moment, there is no need to wait for the campsite or rely on the sun. The hot water and air heater makes the wilderness your warm home.
Space Heating:
- Warms the RV cabin via ducted air vents or direct airflow.
- Ideal for cold-weather camping or overnight stays in mountains.
Hot Water Supply:
- Provides instant hot water for showers, sinks, dishwashing, or outdoor showers.
- Supports hydronic heating systems (if the RV uses heated water for radiators or underfloor heating).
Off-Grid Living:
- Operates independently of shore power, relying on LPG and the RV battery (for ignition/controls).
- Perfect for boondocking or remote locations.
Extended Travel:
- Reduces reliance on campground amenities by providing self-sufficient heating and hot water.
