Best Diesel Heater For Campervan FAQs

Q: What Is a Diesel Air Heater?

A diesel heater is a gadget that consistently releases heat to warm the interior of your vehicle during a cold season. It will heat the air inside your vehicle to warm you up and keep your hands from freezing as you drive. The device takes in the surrounding air and combines it with fuels. When combustion happens it releases warm air that warms up the surrounding environment.

Q: How Do Diesel Heaters Work?

The unit has an external pipe that sucks in air from the environment outside the vehicle. The air is directed to the combustion chamber, where it mixes with fuel. Once the air is automatically ignited, it heats the heat-exchanger’s surface area. Air in the cabin is kept separate from the combustion exhaust air.

The latter is emitted into the open air outside the vehicle using an exhaust pipe. Consequently, the unit’s internal blower motor passes cool cabin air over the heat exchanger for heating. Then this air is taken back to the cabin once more.

Q: Why Choose a Diesel Heater for Your Van?

There are numerous benefits that come with diesel heaters. Some of these benefits include;

  • Increase driving comfort

During a snowfall and the entire surface and outside of your vehicle is covered with ice, a diesel heater warms up the interior of the car, eliminating the cold that freezes your hands. It also warms the seats and your vehicle’s interior components, making the car more comfortable for you and your loved ones.

  • Low environmental impacts

Modern diesel heaters feature low fuel consumption, making them fuel-efficient and economical. They also have low emissions, which makes them environmentally friendly. Furthermore, they eliminate the need to keep your vehicle idling, which produces more emissions, polluting the environment even more.

  • Space-saving

Most diesel heaters are compact and this means that they require small spaces during installation. Their compactness also makes them highly portable when you are on the go.

Q: Are Diesel Heaters Safe?

Diesel Heater image

Absolutely, yes! Diesel heaters are extremely safe. The combustion air is safely exhausted to the car’s exterior. Additionally, diesel gases have upgraded systems that fully combust air. Besides, gases are expelled outside away from vehicle occupants, making it safe to install and operate.

Furthermore, some models come with a thermostat that you can use to adjust the amount of heat needed in the vehicle. Others will come with auto on/off functions to preserve fuel and prevent overheating. Therefore a diesel heater is efficient and safe for your vehicle.
