Frequently Asked Questions
How to choose the right portable car heater
When trying to decide what type of car heater to purchase, consider how much heat you need to warm your vehicle.

Before getting started, make sure you thoroughly go over the instructions. You also need to make sure your diesel heater is filled with fuel before installing it. Here is a YouTube tutorial from Kiwi EV Adventures on how to install a diesel heater in a car.
Are portable car heaters safe?
If installed properly and all safety precautions are followed, then they can be used without issue. Diesel heaters can’t be used in an enclosed space as it could cause carbon monoxide poisoning so you have to leave a gap in the window for proper ventilation. You always have to have it secured in place when using it. If you plan to drive with it installed it has to be somewhere in or on the vehicle where it will remain secure.
Regular heat vs portable heater
Portable heaters can be a great short-term solution for providing heat to a vehicle but they aren’t the same quality or as convenient as standard heat that comes standard in a car.
