As the winter months approach, many of us start thinking about how to keep warm in our cars during the chilly mornings and evenings. One popular solution is the installation of external car heaters. These devices are designed to preheat your vehicle's engine and cabin, making it more comfortable to drive in cold weather. But how do these heaters actually work effectively? Let's take a closer look at the science behind them.
External car heaters typically come in two main types: block heaters and coolant heaters. Block heaters are designed to warm up the engine block, while coolant heaters heat up the engine coolant. Both types of heaters are designed to help your car start more easily and run more efficiently in cold weather.
Block heaters work by using an electric heating element that is installed directly into the engine block. When the heater is turned on, it warms up the engine oil and coolant, which helps to reduce the viscosity of the oil and make it easier for the engine to turn over. This can help to improve fuel efficiency and reduce wear and tear on the engine.
Coolant heaters, on the other hand, work by heating up the engine coolant before it circulates through the engine. This helps to warm up the engine more quickly, which can reduce the amount of time it takes for your car to reach its optimal operating temperature. Coolant heaters are often more efficient than block heaters, as they heat up the entire engine rather than just the oil and coolant.
In addition to block and coolant heaters, some cars also come equipped with cabin heaters. These heaters are designed to warm up the interior of the car, making it more comfortable for passengers on cold days. Cabin heaters can be particularly useful for those who have to spend a lot of time in their cars during the winter months, such as delivery drivers or long-haul truckers.
So how do these external car heaters work effectively? The key is to use them properly and make sure they are installed correctly. It's important to follow the manufacturer's instructions when installing a block or coolant heater, as improper installation can lead to damage to your engine or electrical system.
It's also important to use the heater at the right time. For block heaters, it's best to turn them on at least a few hours before you plan to start your car, to give the engine enough time to warm up. Coolant heaters can be turned on at the same time, or just before starting the engine, depending on the manufacturer's recommendations.
In addition to using external car heaters, there are a few other things you can do to keep your car warm in the winter. One simple trick is to park your car in a garage or use a car cover to help retain heat. You can also use a windshield cover to prevent ice from forming on your windshield overnight.
Overall, external car heaters are a great way to keep your car warm and running smoothly in cold weather. Whether you opt for a block heater, a coolant heater, or a cabin heater, these devices can make a big difference in your comfort and safety during the winter months. Just make sure to use them properly and follow the manufacturer's instructions for the best results.
