Upgrade: The included A2422 wireless temperature sensing switch has a CO alarm that triggers an alarm and triggers an automatic shut-off when unsafe levels are detected. It can also control the heating switch, switch operating modes, adjust operating parameters, set functions, etc. and know the working status of the diesel heater
Quiet operation with quiet fuel pump: The air duct outlet remains the primary noise source (35 dB, corresponds to normal conversation), but our advanced quiet fuel pump eliminates the irritating ticking noise found in conventional auxiliary heater diesel. Perfect for interrupted sleep in trolleys, cabins or tents.
Intelligence and safety: In addition to the support of 12 V and 24 V, the kit also includes a 110-240 V transformer. You can connect the diesel heater directly into a 110-240 volt socket. It offers thermostatic control, timing function, ventilation mode, turbo heat mode and overheating protection of ≥518°F / 270°C to ensure a safe and comfortable experience all night long
Indoor climate control: includes a 4 metre long extension cable that allows you to mount the control panel indoors to facilitate access and operation. By accurately detecting the actual indoor temperature, the diesel auxiliary heater can adjust its operating mode and intelligently switch on and off. This not only greatly improves heating efficiency, but also eliminates the need for frequent outdoor exhibitions, dramatically reducing fuel consumption for superior energy and cost savings.
Fast heating and energy saving: diesel heating uses reinforced aluminium heat exchangers, which increase combustion efficiency by 38% and significantly reduce fuel consumption. It only takes 3-5 minutes to feel the heat, with a consumption of only 0.16-0.45 litres per hour. 6L oil can provide up to 20 hours of heating for a room of 20-25 square metres.
All-terrain adaptive performance: Never lose efficiency in high positions. Our auxiliary heater automatically adjusts combustion for optimal performance up to 5500 metres to ensure full heat generation and fuel economy in mountain landscapes. This intelligent adjustment ensures reliable warmth, whether you're on a high mountain climb or at a remote alpine workplace.
Advanced diesel heater with Wi-Fi control: with the Sunster app, you can manage your auxiliary heater from anywhere in the country as long as it is connected to Wi-Fi. Perfect for families or teams on the go
