Winter is fast approaching and with winter the concern for car heaters that are not working properly arise.

Installation Requirements

If you buy a portable heater for your car you want to make sure that you get one that is easy to install. Some of these devices easily plug into the cigarette lighter port of your vehicle or into an auxiliary port like the one you plug your cell phone charger into.


You can buy just a portable heater or you can buy a unit that is capable of heating and cooling. The versatility of the device will increase the amount of time you use it and this can make the item a better overall value.

Some of these devices also have features that allow them to be perfect for defrosting or defogging a window.

Frequent Asked Questions

1. How Do Car Defrosters Work?

When you turn the dial to the defrost setting the warm air that is produced by your heater will be directed through the ductwork to blow on the bottom section of your windshield.

When this warm air hits the windshield it can clear away the moisture and frost that has accumulated on the glass so you have a clear vision of the road ahead of you. In the majority of cars, the engine of the car must be cranked and allowed to warm up before the defroster will begin to clear your view.

2. Are Portable Car Heaters Safe?

For the most part, the worst thing that a portable car heater can cause is for you to have a blown-out fuse from circuit overload. The majority of these devices are safe and efficient.

There are some precautions you need to take when using propane-fueled portable heaters in your vehicle, like making sure to ventilate properly, and always making sure to cut the device off before you leave the car unattended.

Follow the manufacturer’s recommendations and safety guidelines, and you should be safe and warm while using a portable car heater.

3. Does the portable car heater run when the vehicle is turned off?

For the most part, a portable car heater that is connected to the vehicle will stop working when the engine of the car is not running. If the car you drive has an automatic start/off function installed then when you start the car the heater will start to work immediately without you turning a switch.

If the heater you are using works on propane or batteries independent of the vehicle then the heater will not turn off when the car engine turns off and you will have to manually shut the heater off.

4. How long should it take a car heater to warm up?

Within ten minutes of cranking the car and turning on the heat, you should be feeling the temperature inside the vehicle increase. Some car heaters do not reach their full abilities until the car is driven for a few minutes so in those cars the warm-up time is a little longer.

5. Why is my car heater not blowing hot air?

One problem may be that the coolant you put in your radiator may not be circulating properly through the heater core. This can be caused by a blockage in the small tubing of the core. The thermostat in your car may not be operating properly or you could have broken heater controls. A water leak may also cause your heater to not work correctly.

6. How much does it cost to fix the heater in the car?

Depending on what the problem with your heater is the cost to repair it may be between $300 and $1,000 dollars. There are a lot of things that can go wrong with a car heating system so the price of repairing one will be determined by the problem and whether the car is still under warranty or not.

7. Why does my car heat only work when I’m driving?

The coolant that you place in the radiator of your car heats up as you are driving. As the heated coolant is dispersed through the heater core the air that you feel coming from your vents is warmer than the air was when the coolant was still cold.

Check your heater control valve to ascertain whether it is opening properly and check your coolant levels to make sure that you have the correct amount.

Final Note

If you are interested in a small and versatile unit that can provide extra heat or cooling to the cab of your vehicle you will want to look at the Portable Fan Heater made by ROYADVE. It is easy to install and works by plugging into the cigarette lighter of your vehicle.
