12V 5kW Diesel/Gasoline Engine & Cabin Parking Heater

Reliable Cold-Weather Engine & Cabin Heating

This dual-mode 12V 5kW liquid parking heater is designed to reliably preheat both your engine and vehicle interior in low temperatures. Operating on either diesel or gasoline, it integrates with the vehicle's coolant circuit to deliver stable, even heat for passenger cars, vans, light trucks, RVs and off-road vehicles.

With a thermal output of 5,000 W, the heater warms the engine coolant, which in turn heats the cabin heat exchanger and the engine block. This helps the engine reach operating temperature faster, supports smoother starts in cold weather and improves driving comfort. The unit runs on 12V DC (11.5-16V range) and consumes approximately 0.3-0.31 L of fuel per hour, providing efficient heating with low electrical load (approx. 33 W during operation).

Why It's a Smart Choice

• Dual-fuel compatibility - Works with both diesel and gasoline, allowing installation across mixed fleets or different vehicle types without changing heater hardware.
• Engine protection in cold climates - Preheats coolant and engine components before start-up, reducing cold-start wear, improving start reliability and helping lower emissions.
• Comfortable cabin heating at standstill - Parking heat mode warms the interior and clears frost from windows while the engine is off, ideal for overnight parking and winter mornings.

The system is designed for demanding environments, with an operating temperature range of approximately -40°C to +80°C and altitude capability up to around 5,000-6,000 m. The included LCD switch and remote control (up to about 50 m with obstacles) allow convenient activation and adjustment from inside or near the vehicle.

The package includes the heater unit, LCD switch and remote control, water pump, fuel pump, filter, silencer, fuel and water hoses, exhaust and intake pipes, mounting plate, wiring harnesses, installation accessories and user manual for a complete installation solution.

FAQ

Q: What vehicles is this heater suitable for?
A: It is suitable for most 12V vehicles with liquid cooling systems, including cars, vans, RVs and light commercial vehicles that use diesel or gasoline.

Q: Does it heat the cabin or only the engine?
A: It heats the engine coolant, which can be routed through the vehicle's heat exchanger to warm the cabin and defrost windows, while also preheating the engine.

Q: Can it be used while the engine is off?
A: Yes. In parking heating mode, the heater operates independently of the engine to warm the coolant and cabin when the vehicle is stationary.

Q: Is professional installation recommended?
A: Yes. For safety and correct integration with the fuel and cooling systems, installation by a qualified technician is strongly recommended.
