A diesel heater is more than just another vehicle accessory. On cold nights spent in your vehicle while parked, they can become a vital source of warmth and heat, not only for you but for the vehicle itself, as it avoids any bits from getting frozen.

Control and adjustability

A diesel heater is a great way to heat up any vehicle during prolonged periods of time, as it is convenient and highly efficient.

Look out for diesel heaters that can adjust the temperature, the wind speed, and even the oil quantity. 

Motor and Combustion chamber

The motor and the combustion chamber are where the heating process takes place, and are therefore the most important and essential parts of the diesel heater.

You should always ensure that they are constructed to last, perhaps with a more durable material such as sand-blasted aluminum.

It’s important to choose a high-quality product, as the investment will pay off by allowing the heater to perform in an efficient and reliable way, lasting a lifetime if taken care of properly. 

Efficiency

As the diesel heater will consume fuel from your vehicle, it’s very important to ensure that it is as efficient as possible to reduce fuel consumption and costs on a long-term basis.

You should also look out for energy-saving oil pumps too. And if you want, you can look for a diesel heater that is also as environmentally friendly as possible, by getting a low emission heater. 

You should also look for a diesel heater with a noise-reduction heater so that it is noise-free while remaining highly efficient! 

Design and size

Diesel heaters are very versatile and can be used in any type of vehicle, from cars to caravans to trucks, or even construction vehicles and boats.

If you’re worried about the space they might take up, you can lookout for a diesel heater with a compact and small design, as they are better for smaller or narrower spaces.

They are also a lot easier to install and remain just as effective as the bigger diesel heaters. 

Other features

There are other features that different diesel heaters might include, ranging from things useful for safety to things useful for an added comfort. 

Something that can come in very handy is a remote control so that you can control the diesel heater from a distance, without the need to walk all the way to the car! This means you could set it up from where you are and have the car waiting for you nice and warm. 

As for safety features, the most important one to look out for is the automatic shutdown to prevent any dangerous overheating. 

Frequently Asked Questions

How does a diesel heater work in a caravan?

Diesel heaters work when installed and connected to the fuel deposit, as they use the diesel of the vehicle to be powered up and create heat.

They then direct the cold air with an intake duct that passes through a cylindrical metal surface (which is heated up). The air is therefore heated up as it passes through, with all of the air within the vehicle slowly becoming completely heated and warm. 

Are diesel heaters safe?

Diesel heaters can seem very dangerous, as they are connected to the fuel of the vehicle and use it to create heat within the interior of the vehicle.

However, they are widely used and completely safe and secure. They pass rigorous tests when manufactured, and are therefore perfectly okay to use, even during prolonged periods of time or overnight. 

Most diesel heaters feature an automatic shutdown to avoid any dangerous overheating, so this is something you can look out for if you’re still worried. 

How much fuel does a diesel heater use?

Although diesel heaters use fuel from the vehicle, they are usually very efficient and have a low consumption which saves costs on a long-term basis.

On average, a diesel heater will use 0.1 liters of diesel for every hour.
