WiFi + Bluetooth App — No Distance Limitation

Your Problem: You are still out and about while the van remains ice-cold. By the time you go inside, it takes another 30 minutes to get warm.

What it does for you: Control temperature, timer, plateau mode, and ventilation directly from your smartphone — via WiFi (from anywhere) or Bluetooth (nearby). Start the heat before you return to the vehicle.

• WiFi Control — Pre-heat from anywhere with network connection
• Bluetooth Control — Direct local connection
• Weekly Timer — Up to two start/stop times per day

A2422 CO Alarm & Safety Protection

Your Problem: You worry about carbon monoxide when sleeping in an enclosed space. Cheap heaters have no monitoring.

What it does for you: The A2422 remote features a built-in CO sensor that displays real-time concentration. If the value exceeds the safe limit, the device issues a voice warning and automatically shuts down the heater. You sleep safely while the air is monitored.

• Real-time CO Monitoring — LCD display with backlight
• Voice Alarms — Warning when values rise
• Automatic Shutdown — Heater shuts off if CO is too high
• Wireless Temperature Control — Place remote inside the living area

Constant Temperature + Turbo Mode

Your Problem: Weak heaters do not shut off automatically when it is warm enough, or take forever to heat up the interior.

What it does for you: The ECU only starts when the temperature drops and maintains a constant 20°C. Need quick heat? Turbo mode blows full power within minutes.

Adaptive Plateau Mode — Up to 5,500 m

Your Problem: At higher altitudes your old heater burns incompletely, smokes, or blows cold air because thin air changes the air-fuel mixture.

What it does for you: The updated mainboard reads the altitude and automatically adjusts the air-fuel ratio. No manual tuning, no sooty flame. Clean, strong heat up to 5,500 meters.

Dual Power Supply — 12V/24V DC + 230V AC

Your Problem: One heater works in the van, another at home. You do not want to buy two separate units.

What it does for you: Run the unit on the road from your vehicle battery (12V/24V) or at home from a standard outlet (230V AC). One unit for all situations — in the van, garage, or garden shed.

• DC 12V & 24V — Direct connection to vehicle battery
• AC 230V — Includes power adapter for wall socket

4 m Switch Extension Cable — Flexible Installation

Your Problem: The control panel must stay attached to the heater, even though you would prefer it inside by the bed or at a convenient spot. Rigid cables force you to place the unit exactly where the cable reaches.

What it does for you: The included 4-meter switch extension cable gives you the freedom to place the LCD control panel or remote up to 4 meters away from the heater. Mount the heater box in the trunk and route the control panel into the living area — no extra cables to buy.

• 4 Meter Length — Enough reach for large vans and motorhomes
• Easy Extension — Connect the control panel to the main unit
• No Location Restriction — Place the controls exactly where you need them
• 

Under 35 dB & Extremely Fuel Efficient — 8 kW / 0.16–0.45 L/h

Your Problem: Loud ticking heaters keep you and your kids awake at night. And you do not want to keep refilling expensive fuel.

What it does for you: A silent oil pump keeps operation under 35 dB — quieter than a whisper. The 8KW burner warms up to 20 m² (215 sq.ft.) and consumes only 0.16–0.45 L per hour. The built-in 6-liter tank lasts through long nights.

• ≤35 dB — Quiet operation for undisturbed sleep
• 0.16–0.45 L/h — Extremely low consumption
• 6L Tank — Up to 20 hours of continuous heat

One-Button LCD Control Panel — No Key Combinations

Your Problem: Cheap heaters require holding two buttons for four seconds just to change the fan speed. With gloves on in freezing temperatures, this is nearly impossible.

What it does for you: Ventilation, temperature, and power level each require only one button press. Simple, intuitive, and usable even with gloves.

Safety Features — Overheat Protection + FCC + A2422 CO Shutdown

Your Problem: You do not want to wake up in an enclosed space because a heater overheated or leaked dangerous gas.

What it does for you: Sealed combustion (outside air in, exhaust out), overheat protection at approx. 280°C, FCC certification — plus the A2422 cuts power if CO rises. This is real safety engineering, not a toy.

Toolbox Design — 6L Tank, Fully Sealed

Your Problem: Bulky heaters rattle loose, leak fuel, and take up too much space. You need something portable.

What it does for you: Everything is pre-installed in a rugged, weatherproof toolbox with metal latches. The 6-liter tank is built-in and leak-proof. Toss it in the trunk, take it on the ferry, and it is ready to go in ten minutes.
