Types of Portable Car Heaters
There are three main types of 12-volt portable car heaters. They all have advantages and disadvantages, but it is essential to know what exactly you want to use your portable heater for. Let’s look at them:
Convection portable car heaters
Oil-filed heaters are a part of this convective category. When it comes to cars, recreational vehicles, trucks, and other tightly confined spaces, these are the safest to use.
Convection portable car heaters draw cold air over an electric heating element. They transfer heat into the air around you, which then rises because hot air is not as dense as cold air. This is the reason why cold air then rushes in to fill the void, which in turn rises up and pulls in even more cold air. This cycle is called convection. Therefore, the heaters are referred to as convection ones. These type of heaters work perfectly in vehicles that are sealed up since convection relies on a closed volume of air.
Some convection heaters, however, use heating elements that can pose combustion risks. This is something you need to keep in mind as most oil-filled heaters are thought to be safe, and that is indeed true, but there are always exceptions and risks.
These heaters heat the oil that is sealed inside them, using electricity. Oil-filled heaters don’t actually burn it. The heat from the oil is first transferred to the casing and then to the air circulating the fins. They will take longer to heat your vehicle as they rely on natural convection.
These heaters circulate the heat into the room after they have moved air over a heating element. They will be able to heat your car quickly as they use a fan to move the heated air. Another advantage they have is the fact that they take up less space than convection heaters.
Fan-forced heaters are an excellent option for cold weather as they are specifically designed to blow warm air. A crucial part of their design is the fan, and not the booster as it is with other heater types. Their fans are usually powerful, so they can heat the room quickly and evenly.
However, these products tend to be quite noisy when the fan is on full power. You also need to be careful with them, as they also hold some risks, fire being one of them.
Ceramic fan heaters
Some fan heaters are also ceramic ones so it would be normal to see the term ‘ceramic’ in conjunction with them. This is a safety advantage because ceramic cools faster than metallic heating elements and therefore could reduce a burn risk.
Radiant Portable Heaters
These heaters also use heating elements. The difference is they do not warm up the air around them. Instead, portable radiant heaters emit infrared radiation. This infrared radiation causes a specific object to warm up when it hits its surface.
For this reason, these heaters are also a great option. They, however, do not actually warm up the air around you but are still great at providing heat in poorly-insulated environments like the one of a car.
Bear in mind that some portable radiant heaters are also dangerous to use in confined spaces. This is due to the combustion risks that their heating elements pose.
Portable Car Heater Buying Guide
When you search for a specific product, there are always some particular features you need to keep in mind, especially with so many products for space heating available on the market nowadays. Let’s look at the main factors you have to consider when searching for a portable car heater:
Factors to Consider When Looking for a Portable Car Heater
- Heater type
This is the first and most important factor to think about. In general, there are three main heating technologies: convection, fan-forced, radiant. You need to know what you are going to use the heater for. The same logic is applied even when it comes to selecting a tent heater – a product which we have also outlined extensively.
Convection heaters typically provide a whole-room, even heating; radiant heaters are great when it comes for small spaces, but they don’t really heat up the air; fan-forced heaters have an internal fan that blows across a heating element. The best way to ensure adequate performance is to select the most appropriate type of heater for your application.
When it comes to heating your car, most people prefer to use fan-forced heaters. They do the job quickly and do not require much space.
- Car size and cold climate
If your car is a bigger one, then you are probably in the wrong place. Portable car heaters are suitable mostly for small vehicles. Ensure that your heater is at least 150W and avoid ceramic units. Ceramic is considered to be a “lazy” provider.
If you live in a cold atmosphere and/or your car is indeed significant, but you still want to get a portable car heater, we would recommend that you go for a diesel one. However, you may want to choose a model that is an inline one because the ones that need to sit in your car have too many risks.
The noise a particular product makes while operating is a significant factor. This is mainly true when we talk about car heaters. Look for a product that you won’t even know is working. Always read the product’s description and the reviews other users have written.
- Heating capacity
The size of the space a heater can cover is essential. The heater wattage rating is what determines this. A good practice of thumb is that a typical 1,500-watt heater will be able to cover rooms as large as 150sq.ft. When it is used as a supplementary source of heat. Usually, a room heater uses 10 watts of heating power so that it could heat each square foot of the space. This, however, does not apply for every model.
- Energy efficiency
This factor applies to almost all the products that require electricity. Locating the most energy efficient window air conditioners or the most energy efficient coffee maker is pretty much one and the same thing. Currently, portable electric heaters lack a standard level of efficiency like the EER ratings that mobile AC systems have. Still, features such as energy saving modes, low wattage, adjustable thermostats, and programmable timers will undoubtedly contribute to more economical operation.
How Do Car Defrosters Work?
When we talk about cars, it is essential to know what a defroster is and how do car defrosters work? Let’s look at the different defrosters your vehicle has, and the ones that you can get besides.
- Primary car defrosters
These are defrosters that utilize the HVAC system of your vehicle. They are also referred to as defoggers since they are designed to clear your windshields. With the primary car defrosters, the HVAC system draws in fresh air, passes it through the heater core, and then directs the warm air through dashboard vents so that it could hit the side windows and the front windshield. The primary defrosters not only defrost your windows but they also ‘defog’ them by removing condensation from the inner surface. It is possible to accomplish the same moisture removal by physically wiping the condensation away, but this may lead to smudges.
- Secondary car defrosters
They do not use your vehicle’s HVAC system and are designed to defrost things such as mirrors and rear windshields. Typically, these systems use wire grids and resistive heating to warm up the surface of the class. This way ice is melted effectively, and condensation is removed quickly.
- 12V car defrosters
Driving with a busted defroster when it is freezing outside is a total nightmare. The worst thing after driving your car in a sub-zero temperature is standing out in that same weather, trying to remove the thick layer of ice on your windshield.
If this scenario is something you do not want to experience, you may want to get yourself a 12V defroster or heater. The most common power supplies these devices use are the cigarette lighter sockets. However, since 12V accessory outlets and cigarette lighter sockets are usually fused at 15A or less, it is pretty much impossible to run a very powerful heater from them. That’s why, when using a 12V defroster, expecting to have the same results as the ones you got from your HVAC system is wrong.
The Importance of Giving Your Car Time to Defrost Before Driving
The importance of giving your car time to defrost before you take off is significant. We all understand how disturbing it is to find your car frozen when you need to go someplace as fast as you can. You are in such a hurry, and you barely scrape anything off, hoping that your car defroster will do the job for you while you drive. However, driving with frozen shields is incredibly dangerous, and you always need to give your car some time to defrost.
Just do it. We know that it is cold outside and you hate your life right now, but the few minutes that you are going to spend scraping your car could save you from disaster.
Providing the safest conditions possible while driving is your responsibility for if something happens you are endangering not only your own but the lives of the people around you as well. When there are ice and snow on your windshield, your visibility is greatly hindered. Just imagine how many accidents happen because of the blind spots every car has. Well, now imagine adding ice and snow to that, it is even more dangerous.
You will increase the hazardous conditions around you if you drive down the highway or other roads with snow and ice coming off your car. What happens if it hits another car? You would be the main reason for an accident without even imagining that something like this is possible. Well, it is, and that is why you need to be very careful when it comes to defrosting. Spend some extra ten minutes and defrost your vehicle correctly.
- Fuel Efficiency
If you don’t wait enough time for your car to warm up, it is entirely reasonable that your MPG drops between 12 and 20 percent. Many factors contribute to this lessening of fuel efficiency – battery performance, tire pressure, oil viscosity. All these are affected by cold temperatures.
The EPA also recommends to warm up tour car on freezing days and wait for it to defrost. However, some vehicles have computer-controlled fuel injection, and their engine will pretty much warm up faster when the car is driven.
When Do I Need a Car Heater?
This is a question that has undoubtedly bothered you, but in reality, the answer is super easy. These are the main reasons why you would like to get yourself a car heater or defroster:
- You live in a region with a cold climate
This means that you will have a hard time warming up your car and an additional car heater will be a great solution.
- You have a larger vehicle
From one side it is better to have a smaller vehicle because then the portable car heater will do its job quickly and easily. But then if you have a small car and your primary heater works, why would you need a portable car heater? On the other hand, if you have a large vehicle, you will want all the power you can get to warm it up more quickly. For readers with larger cars, we would recommend diesel heaters.
- You spend many hours driving
If your work requires many hours of traveling- taxi driver, for example, you surely need this kind of heating gadgets.
- Your primary car heater is damaged.
If that is the problem, you will see how expensive it could be to fix your heating system. Sometimes, people prefer to buy a portable car heater until they can pay for the repair of their car. Some portable heaters are really, and at the same time cheap, so they are an excellent option for situations like this one.
- Do you want to defrost your windshield easily?
Since most portable car heaters can not only warm up the air in your car but can also defrost your windows, they are something you just need to have. If you live in a cold area and a frozen windshield is something you are not unfamiliar with, a portable car heater that can work as a defroster would be a reasonable choice.
Advantages of Using a Portable Car Heater
If you think about getting a portable car heater, there is a huge possibility that your primary car heater is damaged. If that is the case, you already know that repairing it means money and depending on your car model and brand we may be talking for a lot of money here. A portable car heater will cost you less as some models are really cheap.
Traveling in winter is not fun at all, especially when you live in an area where there is a lot of snowfall and frost. If you have such a device, it will be easier for you and your car to move through the cold weather.
Many portable car heaters will not only warm up the air in your car making you feel like home but will also help you defrost your windshield. This means that you will not have to stay out scraping the ice off your car for two hours.
Are Portable Car Heaters Safe?
Fire hazards are something that comes to mind after we have decided to use a portable car heater. Combustible materials inside your car are something you should be careful with. You need to consider everything from upholstery that isn’t flame retardant to loose papers. The good thing is that unlike residential space heaters, these devices are designed to be used in tight quarters. However, every car is different, and you need to be super careful.
In general, oil-filled heaters do not create the same type of combustion hazards that you can see with other types of heaters. However, they take longer to warm up and may not be suitable for your needs. If there are any potential hazards in your car, mount the heater a safe distance from them.
Because of the information mentioned above, it makes sense to say that a portable car heater is safe to use. Remember, though, that like with any other thing there are always some risks and you need to be very careful. Always follow the instructions that you are given. If you have not read the guideline, don’t try to install a 12V car heater.
More importantly, stick to what the manufacturer has recommended. If the portable car heater you have bought is only meant for mounting on your car’s dash, don’t try to install it anywhere else. If your device requires a bracket for proper installation, use brackets and do not experiment. If you have no idea about the method to install or mount and the specs of a particular product, just don’t try to attach it on your own.
Car Heating Tips
Apparently, our team recommends that you get yourself a high-quality portable car heater. They are, after all, guaranteed to give you comfort and warmth. Still, there are some other methods and tips you could use to feel warmer in your vehicle.
Alternative Ways to Keep Yourself Warm in Your Car
- Layer Up
If you are someone that deals with seasonal snow, then you need to have a few blankets waiting for you in your car. This is a must-do for every car owner. If something happens and your heater stops working, these could save your life…literally.
It will be even better if you buy thermal blankets. Another option could be the winter sleeping bags which are an excellent choice when it comes to battling the cold.
We also recommend you to have some extra sweatshirts, mittens, sweatpants, and thick socks. This is not something we wish you to experience, but if you get stuck in the cold, these will keep you warm and comfy. When you layer up as much as possible, you can preserve body heat.
- Temporary Warmth
There are many items on the market now that are affordable and will provide you with momentary warmth when you are in your vehicle. Disposable heating packets, for example, are great for your hands and feet. They are able to give you instant warmth for about one or two hours. All you need to do is follow the directions written on the package. Believe it or not, these come in many sizes, and the smaller ones can even be tuck inside your socks.
- Run your vehicle
If for some reason you get stuck in the snow, and you wait for help, remember that turning off the car while waiting is not a good idea. Well, actually it will be best if you turn it off but run it for at least 10 minutes every hour or so. This way the vehicle itself can give you some warmth, and you will keep your battery charged. Also, always check your tailpipe for clogging.
Tinting gives you a layer of insulation so your car will be able to keep the heat during winter. Thanks to this extra insulation, warming your car will not take much longer.
