Expensive is not necessarily good, and may not be suitable for you. The parking heater is the most advanced product that has emerged in recent years and is the most advanced product that solves the problem of low-temperature start of cars in alpine regions. Different brands have also appeared on the market. Some are expensive and some are cheap, so what issues should we pay attention to when choosing?
The first point: due to the space limitation of the heaters used in cars, parking heaters are very small, but the engine requires a lot of heat, so the heater power is required to reach at least 5KW! In other words, it is not only small but also to achieve maximum thermal energy conversion to achieve maximum heat utilization.
The second point: The most important point is the power consumption problem. Electricity-is the heart of the vehicle! No power, no function to talk about! The heater works most of the time when the vehicle is stationary. At this time, the battery power is not replenished, only consumed. Especially in winter, the battery power is generally low. Therefore, it is most critical to ensure that the vehicle has enough power to start after the engine is warmed up.
