12-volt Car Heater Buying Guide
Types of Car Heaters
Mainly, there are 3 types of car heaters. They are fan-forced car heaters, convection car heaters, and radiant car heaters respectively. Let’s elaborate…
Fan-Forced Car Heaters
This is the most common car heaters you will see. Matter of fact, almost all of the car heaters we have talked about in this post are of this kind.
This type of heaters actually works like a typical fan. It will take the normal air from the environment and will pass it through a heating element.
As a result, the cold air will be turned into hot air. And, the fan will circulate the hot air into the room. This tends to be cheap and easy to operate.
On the other hand, the fan might make a tad bit of noise while blowing the air out at the high setting.
Convection Car Heaters
As the name suggests, this type of car heaters uses the convection method to heat up your car. It will convert the cold air to hot air of the surroundings.
During that period, the hot air will rise up and will create a void for more cold air to enter. Over time, the cold air will turn into hot air and the environment will be filled up by hot air.
If your vehicle is sealed up, then it will be wiser to use convection car heaters. Also, as this type of heater completes a cycle over and over to generate hot air, it will take a lot of time to heat up your vehicle using this type of car heaters.
And, that is one of the main reasons, we haven’t included them in this review of the best 12-volt car heaters.
Radiant Car Heaters
This type of car heaters uses infrared radiation to heat up the air. It will heat up the area where the infrared radiation will hit.
Due to this process, it is better to use this heaters to warm up any specific object. So, it is not a good idea to use radiant car heaters to keep a big area warm.
