Electric heating and fuel heating have their own advantages. Electric heating is more convenient and trouble-free, almost no noise, no exhaust gas, and no need to worry about exhaust gas poisoning. However, the electric heating power is generally relatively large. To obtain the ideal temperature, the electric heating power is usually above 3kw. The capacity of the RV's battery is limited. The 12V400Ah battery pack can only store 4.8 kWh of electricity. High-power use of electricity will further reduce the discharge capacity. In the end, the 3kw electric heater can only work for about one hour. Electric heating is only suitable for use when there is an external power supply in the camp. There is almost no way to use it for a long time without an external power supply. You can never use a generator to generate electricity for heating!
Fuel heating is currently a relatively mature heating device. The heating power is large, and the heating power of 3-5kw can still be warm as spring even in the environment of -30℃. Truck drivers in cold areas only need to wear pajamas when they are equipped with diesel heating facilities. Diesel heating has a relatively high energy efficiency. The use of diesel to obtain heat is like burning a boiler, which is much more efficient than other heating methods. For example, the heating system of a car uses waste heat from the engine. The engine must run for a long time. Even in such a high-cold area, the engine temperature rises slowly and it is difficult to achieve a satisfactory heating effect. Fuel heating is more direct and faster to obtain heat by burning diesel.
