Our Tips and Tricks
If you’re not familiar with mounting diesel heaters or have limited space to set one up, we’d highly recommend finding an all-in-one unit. Because many of the major components are housed inside them, this saves a ton of space and setup time since you won’t have to mount each part to your vehicle. Setup for these units is usually fairly straightforward, but if you find yourself running into difficulties, there are tons of great resources online to get you up and running. Getting an idea of what the process should look like might just save you a significant amount of time as you try to install the unit in your own vehicle.
Frequently Asked Questions
What advantages does diesel have over regular gasoline?
Diesel is a much thicker fuel than gasoline, so it burns more efficiently and provides more power than regular gas. It’s also less flammable than gasoline, which makes it significantly safer to use for heating your vehicle. Price-wise, diesel used to be much cheaper than gas, though that’s no longer the case in many parts of the country.
How do diesel heaters keep from overheating?
Most diesel heaters have overheating protection by utilizing a heat sensor that will automatically shut off the unit’s operation when it climbs to a certain temperature. This is meant to not only protect you from any potential danger but also to preserve the life of the heater. If you find your heater is overheating, there may be an internal problem with one of the parts. Monitor your heater to keep an eye on any problems, such as smoking or extremely hot temperatures. If you’re able to save your unit from burning out, it could save you a meaningful amount of money in the long run.
