Understanding diesel campervan heaters
Wondering how to heat your RV in the winter? The good news is an RV diesel heater means you can travel comfortably year-round in New Zealand. Here’s what you need to know to choose and maintain the right one for you.
How diesel heaters work
At the heart of every RV diesel heater is a simple yet effective mechanism designed to keep you warm, no matter how chilly it gets outside. Diesel heaters operate by drawing fuel directly from your motorhome’s main diesel tank. This fuel is then burned in a controlled combustion chamber, where it generates heat. The magic happens when this generated heat is distributed evenly throughout your motorhome using a small fan. Unlike their gas counterparts, RV diesel heaters are known for their efficiency and safety, providing a steady, reliable source of heat that doesn’t rely on electrical connections or gas lines.
Diesel heaters are adept at maintaining an optimal temperature, thanks to advanced thermostatic controls. This means they adjust their output based on the inside temperature of your motorhome so you can stay comfortable without manual adjustments. If you have a caravan or petrol motorhome, you can buy an optional diesel fuel tank.
How to use a diesel heater safely
Using a campervan diesel heater safely is paramount, not just for the longevity of the heater but for your safety and comfort as well. To ensure that your journey remains both warm and secure, here are some essential safety tips:
- Proper installation: Always have your RV diesel heater installed by a qualified technician. Correct installation reduces the risk of improper exhaust release or electrical issues, which are critical for safe operation. Ensure that the installation complies with manufacturer guidelines and local safety standards.
- Regular maintenance: Like any vehicle component, a campervan diesel heater requires regular maintenance to operate safely and efficiently. Check for and clear any obstructions in the exhaust and air intake pipes before you start your heater. Regularly inspect the fuel line for leaks and ensure that all connections are secure.
- Ventilation: Even though RV diesel heaters are designed to be very safe, adequate ventilation is crucial to prevent any buildup of exhaust fumes inside your motorhome. Always ensure that your vehicle is sufficiently ventilated while the heater is in use.
- Carbon monoxide detector: Diesel combustion, although generally clean, can produce carbon monoxide if the combustion process is incomplete, which might occur due to issues like clogged exhaust systems or insufficient oxygen. Since carbon monoxide is odourless and colourless, having a detector ensures that you are alerted to any potential hazards early. Regular testing of the detector is also important to maintain its effectiveness and ensure your safety on the road.
- Follow operating instructions: Always refer to the manufacturer’s manual for specific operating instructions and safety warnings. Use the thermostat and timers on your heater to manage heating times and temperatures efficiently.
The benefits of using a diesel heater in your motorhome
Let's explore the key benefits that make diesel heaters a smart choice for travellers seeking reliable and efficient warmth on the road.
Superior heating performance
Diesel heaters are renowned for their superior heating performance, providing a consistent and powerful heat output that can handle even the coldest climates with ease. Unlike other heating options that may struggle to distribute heat evenly, diesel heaters use a forced air system to circulate warm air throughout your motorhome, ensuring no corner is left cold. This ability to deliver steady, reliable heat makes them ideal for those chilly nights in remote locations, ensuring your comfort no matter where you are parked.
Cost-effectiveness
One of the most appealing aspects of diesel heaters is their cost-effectiveness. Diesel fuel generally offers a higher energy content per litre compared to gasoline, which means more heat per dollar spent. Additionally, RV diesel heaters are designed to be extremely fuel-efficient, often running for hours on a minimal amount of diesel. This efficiency translates into lower running costs over time, making it an economical option for frequent travellers.
Enhanced comfort and control
Diesel heaters for caravans and motorhomes also provide enhanced comfort and control over your heating environment. With adjustable settings and thermostatic controls, you can easily set your preferred temperature, ensuring your motorhome stays warm and cosy without overheating. Many models also come with timers and remote controls, allowing you to warm up your space before you even step inside. This level of control not only contributes to a comfortable living environment but also helps in managing fuel consumption, making your heating system both effective and efficient.

How to choose the right diesel heater for your motorhome
Not sure how to choose the right diesel heater for your motorhome? Let's break down some of the key considerations:
How often will you use it?
For those who plan to use their motorhome predominantly in winter or in cooler climates, a high-performance RV diesel heater with robust capabilities is essential. Conversely, if you only occasionally face cold conditions, a smaller, more economical model might suffice. Evaluating how often you’ll need the heater will guide you in selecting a model that offers the best balance between performance and cost.
Technical factors to think about
When looking into camper heaters, there are a few technical factors to consider. The efficiency of the heater, its fuel consumption, and the type of climate control it offers are important. You'll also want to consider the noise level – some heaters operate more quietly than others, which can be a significant factor if you value a quiet environment. Additionally, ensure the heater is compatible with your motorhome’s existing systems and that it meets safety standards specific to your vehicle’s setup.
Capacity and outlet options
The capacity of your campervan diesel heater is fundamental to ensure it can heat the entire space of your motorhome without overworking. Most RV diesel heaters come in either 2KW or 4KW capacities. A 2KW heater is generally sufficient for most motorhomes, while a 4KW heater is better suited for bus conversions and larger RVs. You’ll also need to consider the number of air outlets and their placement options. A system that allows for multiple outlets can distribute heat more evenly, enhancing overall comfort. This is especially important in larger motorhomes, where heat distribution can be challenging.

How to install a diesel heater in your motorhome
Installing an RV diesel heater in your motorhome is a task that demands precision and expertise to ensure both safety and optimal performance.
For motorhomes that run on diesel, the installation process is generally straightforward, as the heater can be connected directly to the main fuel tank. However, for petrol-powered motorhomes, additional steps might be required, such as installing a separate diesel tank.
It’s highly recommended that you engage a certified professional for this job. Your local RV Super Centre can take care of installation for you, giving you peace of mind that everything is done correctly and efficiently.
How to make the diesel heater in your motorhome last longer
Ensuring the longevity of your campervan diesel heater involves regular maintenance and being prepared to troubleshoot common issues. Here’s a look at some of the basics:
Routine maintenance
Routine maintenance is key to extending the life of your diesel heater for your motorhome. Here are some essential tasks to include in your maintenance routine:
Regular cleaning:
- Clean the air intake and exhaust vents to prevent blockages that can reduce efficiency.
- Check the combustion chamber and remove any soot buildup to ensure optimal performance.
Inspect fuel lines:
- Look for any signs of wear, cracks, or leaks in the fuel lines.
- Ensure all connections are tight and secure to prevent fuel leakage.
