Sunster TB10 8 kW Diesel Air Heater

This compact diesel air heater combines portability with dual-power flexibility to keep vans, RVs and small cabins warm on cold mornings. The Sunster TB10 fits into a toolbox-style casing with a 6-litre integrated fuel tank and an easy-carry handle, offering quick heat delivery for parking, camping or mobile workspaces thanks to its fast warm-up and low fuel consumption.

Key Points

The unit warms a space of around 20–25 m² and, according to the manufacturer, can run for up to 20 hours on a full 6-litre tank depending on settings. It supports both 12 V DC and 110–240 V AC power, switching automatically between vehicle and mains supply. App control via Bluetooth allows temperature setting, timers and altitude mode from a smartphone. Noise is kept low, with the main audible source being the air outlet at approximately 35 dB, while an improved fuel pump reduces ticking sounds. Note that actual run times and noise levels may vary with installation and environment.

Usage Recommendations

Place the heater in a well-ventilated position inside a vehicle bay or a designated external housing for cabins, ensuring exhaust and air intake ducts are safely routed. Use the Bluetooth app for remote start, temperature control and scheduling to preheat the interior before occupancy. For overnight sleeping in vans, set a lower constant temperature and use the quiet pump mode to reduce disruptions.

Advantages

The toolbox design keeps the installation footprint small and makes carrying and maintenance straightforward. Reinforced aluminium heat exchangers increase combustion efficiency, which, according to the manufacturer, reduces fuel use compared with older designs and delivers heat within 3–5 minutes of start-up. Adaptive combustion across altitude changes maintains performance when travelling in mountainous areas, which can be particularly useful for high-elevation camping or work sites.

Practical Tips

Allow space around the casing for service access and inspect fuel and exhaust lines periodically for secure connections. Consider mounting the control panel within reach; the supplied 4-metre LCD extension lets you position the wired controller where it is most convenient. Remember that ventilation requirements and local regulations for fuel-burning appliances vary, so installation should follow vehicle or building guidelines and, if unsure, be carried out by a competent technician.
