Sunster 8KW Portable Diesel Heater 12V–240V 🚐

This portable 8 kW diesel air heater is designed to keep campervans, motor-homes and trucks warm while using minimal fuel and offering versatile power options. It combines a compact blower design with thermostat control and app connectivity to maintain comfortable interior temperatures during overnight trips or long stays in cold weather.

Key Points

The heater runs at 8 kW and, according to the manufacturer, reaches heating efficiency of ≥90%, which helps reduce diesel consumption. It supports DC 12 V and 24 V for vehicle use and AC 110–240 V for mains connection, allowing automatic switching between power sources when required. The unit includes an LCD monitor and offers Bluetooth app control for setting programmes and checking performance from a smartphone. 🚐

Noise levels are kept low thanks to an upgraded silent fuel pump, with the air duct outlet noted as the main sound source at around 35 dB, comparable to normal conversation. The design includes an efficient internal circulation system with air hot pipes on either end of the unit to reheat and recirculate air, limiting fuel use and helping prevent water ingress. 🔧

Technical Specifications

• Name: Sunster 8KW Portable Diesel Heater
• Power output: 8 kW
• Power supply: - DC 12 V / 24 V and AC 110–240 V
• Coverage area: - Approximately 20 m² (215 ft²) continuous heating
• Noise level: - About 35 dB at the air outlet
• Fuel consumption: - Around 1 US gallon per night (manufacturer estimate)

Usage Recommendations

Use the ventilation mode on warm days to circulate air without heating, which also reduces condensation inside vehicles. Install the included 140 mm base bracket to help prevent exhaust blockages and to secure the unit in a fixed position, particularly in mobile installations like vans and RVs. The app control and preset schedules make it practical to warm cabins before sleeping or to maintain a steady temperature while parked.

Advantages

The combination of dual power inputs and automatic switching makes the heater flexible for mixed travel scenarios where mains power may be available at campsites. The built-in safety protections cover overheating, reverse polarity, short-circuit and over-voltage situations, adding peace of mind during unattended operation. Consider that manufacturer figures for fuel use and coverage are estimates and real-world consumption will depend on insulation, outside temperature and how long the heater runs. 🔋
