Portable 12v Car Heater Buying Considerations
Heating Capacity and Noise Level
When searching for the perfect 12-volt car heater, you should first consider the capacity of your potential heater and the noise level the heater might cause within your vehicle.
The amount of space that a heater can cover is essential to determining if it will be a good fit for you and your needs. A good rule of thumb is that a heater will use 10 watts of power to heat a square foot of space. This doesn’t apply to every heater model, of course, but it’s a good baseline to figure out what kind of output you need to be searching for.
Noise is a contributing factor if you’re someone that likes to listen to the radio, podcasts, or even conversation within your own vehicle. Additionally, a heater that is too loud may make it difficult for you to hear outside forces, like trains or brakes. Most people opt for heaters that they cannot hear working.
There are primarily three types of 12-volt car heaters available on the market. Each has its own pros and cons, but it’s essential to know what you’re looking for when you begin your search.
Convection portable car heaters are arguably the safest kind of portable car heater to use. They draw the cold air over an electrical heating element and then transfer the heat into the air in the space. The heated air rises because it is less dense than the cold air, and more cold air is then pushed into the heater.
Convection heaters work best in vehicles that are sealed up since the convection method relies on having access to a closed volume of air for circulation and heating.
Additionally, some convection heaters use oil. These oil-filled heaters heat the oil sealed inside of them using electricity. The oil is not actually burned, however. The heat from the oil is transferred to the surrounding casing and then to the air circulation system. Oil-filled heaters tend to take longer to heat your car because they rely on natural convection rather than forced-air convection.
Fan-forced heaters also heat air over a heating element within the unit. They will warm your car’s air space quickly because they use a fan system to redistribute the heated air. These heaters are fantastic options for particularly cold weather, and as an additional bonus, they take up much less space than convection heaters.
The downside to these fans is that they are usually very noisy when the fan is on full power. They also may hold some fire hazard risks depending on the placement of the heating element and any surrounding clutter in your vehicle.
There are also ceramic fan-forced heaters, which are usually safer than the traditional heaters as ceramic cools more quickly than metallic elements will. This reduces the risk of fire or burning.
The final type of car heater is the radiant portable car heater. These also use a heating element to bring warmth to your vehicle, but instead of circulating warm air or forcing it out, these heaters emit infrared radiation. Infrared radiation causes specific objects to warm up as the radiation comes in contact with the surface of the object.
This makes them great for small spaces, where all of the surfaces are nearby, even though they do not warm up the air directly. Be sure that they are not close to any combustible materials and remain in a clutter-free space, as they can pose a fire hazard under these conditions.
Your Car’s Size and Climate Conditions
The larger the vehicle you’re trying to heat, the less helpful you’ll likely find a 12-volt car heater to be. Portable car heaters are generally best used in smaller vehicles. If you live in consistently colder climates and your car is larger, you may want to get a portable diesel car heater. Keep in mind that you’ll want to choose an inline heater of that type, though. Make sure that your chosen heater is at least 150W, as well.
