Obviously, our recommendation is to use one of the aforementioned portable car heaters. They are, after all, guaranteed to provide you the warmth and convenience. Anyway, there are also different ways to keep the frosty temperature away.

Layer Up

This is certainly a must-do for every driver out there. As someone who is dealing with seasonal snow, you need to have a few blankets ready in your car. If for some reason your 12v car heater is not working, the blankets can come in very handy. Make sure you buy thermal blankets. You can also go with a winter sleeping bag, which is really a good idea to battle the cold.

Moreover, always remember to keep some extra sweatshirts, sweatpants, mittens, and thick socks. They can keep you warm and comfy, most especially if you get stuck in the cold. The idea is to layer up as much as possible, so you can easily preserve body heat.

Temporary Warmth

In case you did not know, there are a handful of affordable items that can provide you with temporary warmth in your car. For starters, you can go with disposable heating packets. They are a recommended tool when trying to stay warm, and are perfect for your hands and feet. All you need to do is follow the directions stated on the package. They are enough to give you instant warmth for about an hour or two.

Your best course of action here is to stock up on different sizes. That way, you can just place them against your legs or back. You can even tuck the smaller ones into your socks. Believe it or not, these are really beneficial; hence, they are an excellent investment to have.

Always Run Vehicle

Let’s say you are, for whatever reason, stuck in the snow. At first, you might think that running the car is a poor idea. In reality, if you run it every hour and for at least 10 minutes, the vehicle itself can give you the warmth. Above all, it keeps the battery charged, so you can just drive out as soon as the weather clears. Oh, do not forget to check your tailpipe and must not be clogged. Otherwise, you will not be able to go from Point A to Point B.

Use Tint

In case you did not know, tinting your vehicle’s windows can help you ease the stress of winter driving. Yes, that is right. This is due to the fact that tinting provides you a layer of insulation. As such, your car is able to keep the heat in during the winter cold months.

Thanks to this extra insulation, you will not take much longer warming up your car. You can just start driving your vehicle and warming it up fast, so you can just start a better day.

Buy A Car Heater

This is without a doubt our most recommended thing to do. When all else fail, the one thing you can work with is a car heater. But what if it is broken or it no longer gives the right amount of warmth? Well, no need to worry – you can always a portable car heater. This could be a 12v car heater or RV heater, depending on the type of your vehicle. This device can be plugged into your car’s interior power socket and should be enough to deliver the comfort you need when driving.

Higher Fan Speeds Help the Backseat

Sure, you may feel comfortable when you set the heater to a low fan speed. Just keep in mind, however, that this is not the same as the individuals in the back. It will not be enough to keep them warm; hence, you will have to find a way around it.

Your best course of action is to crank up the fan. You need to do this even it results in you having to turn the temperature a bit lower. By doing so, you can ensure that everyone inside the vehicle is comfortable and warm.

Maintenance Tips For Your Car Heater

Car Heater Maintenance

When winter is around the corner, you should already have an idea or two about how you can maximize your vehicle’s heater. Otherwise, you will have a hard time keep you and your passengers comfortable.  Here are some maintenance tips to keep in mind!

Get the Car Moving

It holds true that modern cars do not require much when it comes to warming up before moving. However, if your vehicle is not moving, it is going to need a lot of time before it starts to warm up. In other words, it is better to move as soon as you can, so the engine can start working. Only then will the vehicle generate heat, which is needed to warm you and your passengers.

Highest Setting Will Not Speed Up the Heat

Does your car come with an automatic climate control? If so, know that you can always set the system according to the temperature you like. Whatever it is, it will still be able to warm up. Think of this process as something that is akin to the thermostat in your home.

Basically, the system is capable of sensing the temperature of the air being blown inside. When it notices that the air coming out is already hot, it will start to increase the fan speed. So if you crank the temperature and the fan to high, you and the passengers will be forced-fed with a deluge of freezing-cold air.

Just Keep the A/C On

For most drivers, they believe that A/C means cold air. Well, not really. Keep in mind that the button found on your dash controls the very air-conditioning compressor. The latter simply has the most important role when the temperature starts to dip, and it begins to dehumidify the air. To put it simply, the car’s window will start to fog up as soon as you shut it off.

So no matter how much warm air you want from your system, the turning the A/C on will start to cool the cabin air down and bring it to above freezing right before it starts to be reheated. If you do this, you can easily remove moisture from the air, which, in turn, collects on the cold glass. When this happens, you will definitely have a hard time seeing out.

Safety When Using Portable Car Heaters

Based on the above-mentioned information, it makes sense to say that a portable heater for car is safe to use. They are also durable enough to veer away from any damage. Remember, however, that they can still cause a lot of safety issues, and it is something that you do not want to happen. So, as much as possible, you need to follow the instructions. Do not install a 12v car heater if you did not read the guideline.

More importantly, you must stick to what is recommended by the manufacturer. If the portable car heater is only meant for mounting on your car’s dash, then do it. If it requires a bracket for proper installation, then do not forget to use the bracket. Lastly, make sure that you only use the right type of portable heater for your car or whatever vehicle you have. Do not attempt to install one if you have no idea about its specs, let alone the method to install or mount it.

Final Thoughts

Well, there you have it. You finally have a concrete knowledge about a portable car heater and its importance. Again, remember to follow the guidelines and ask someone knowledgeable to install it if you are reluctant. Portable car heater is one of the best things out there if your car heater or whatever vehicle heater you have, goes off. But as far as their efficiency and reliability are concerned, it totally depends on you.

If you want to steer clear from the expensive cost of repairing a car’s heater, you should consider using one. Not only does it provide you the much-needed convenience and warmth, but it is also a lot more affordable.

    Hi if I buy modified sine 1500 watts inverter and I have 750-1500 watts ceramic heater! And I only used the 750 watts? My battery is still drain even I’m driving for hour or more than? And the ceramic heater are work on 1500 watts power inverter? Thank you

      Hi Eddel,

      What’s your car’s battery capacity? The battery capacity is expressed by amp-hour. We can use this equation to solve your problem:

      Assuming you have 12v, 100 amp-hour car battery capacity and you need a 750 watt heater to run:
      Volts x Amperes = Watts
      to get the amperes:
      Amps = Power/Voltage
      750 watts/12v = 62.5amps

      100amp-hour/62.5 amps = 1.6 hours

      Assuming the battery is full and the weather is normal, you’ll get 1.6 hours of heater operation.
