Planar 2D Smart Air Heater

The Autoterm Planar is our most recommended option. With over 1000 fits to date, the Planar heater is without a doubt the most reliable and trusted brand in the UK market right now. The intuitive design, simple operation and powerful heating motor makes this heater a must-have in your campervan.

We believe that the Autoterm heater is the best option for quality, reliability value for money as the price is much lower than the Eberspaecher, whilst still retaining all of the same features, yet improving upon the Eberspaecher due to the new Super Silent Pump that is now standard on all of our Autoterm Planar Kits.

The 7-day timer allows you to set a specific day and time for the heater to power itself on and kick into action with a specified temperature and run time. For example, in the winter months, if you are using your vehicle daily, you could set the heater to turn on Monday-Friday at 7 am for 30 minutes, so that when you entered the vehicle for the daily commute, you would find yourself coming out to a warm, and best of all, defrosted vehicle. All without having to press a single button. The controller also has a self-regulating thermostat which means you can set the temperature that you desire, and leave the heater on overnight. The heater will power itself on and off throughout the night, keeping the vehicle at a comfortable temperature without any human input.

I recently had the pleasure of getting…I recently had the pleasure of getting a pop top and diesel heater/window fitting installed in my campervan by Cosmic Campers, and I couldn't be more satisfied with the entire experience. From start to finish, the service was outstanding, and the results have significantly enhanced my van life experience.First and foremost, the team at Cosmic Campers demonstrated exceptional professionalism. They took the time to understand my specific needs and provided detailed explanations of the different options available. This personalized approach made me feel confident in my choices and ensured that the final installation would meet all my requirements.The installation process was smooth and efficient. The technicians were punctual, skilled, and maintained a clean and organized workspace. The pop top has been a game-changer, offering extra headroom and a comfortable sleeping area that has transformed my campervan into a more spacious and versatile living space. The quality of the materials and craftsmanship is evident, and I can tell that this addition will last for years to come.The diesel heater/window fitting has been equally impressive. The heater quickly warms up the interior, making it cozy and comfortable even on the coldest nights. The window fitting was done with precision, ensuring a perfect seal and excellent insulation. I particularly appreciate the attention to detail that went into integrating these features seamlessly into the existing structure of my van.Moreover, the after-sales support has been top-notch. Any questions or minor adjustments I needed were promptly addressed, demonstrating the company's commitment to customer satisfaction.Overall, I highly recommend Cosmic Campers for anyone looking to upgrade their campervan with a pop top and diesel heater/window fitting. Their expertise, quality of work, and outstanding customer service make them the go-to choice for van conversions and upgrades. My campervan is now more comfortable, functional, and enjoyable thanks to their excellent work. Thank you, Cosmic Campers

I recently purchased a VW transporter pop top roof from Cosmic Campervans in Derby and I am extremely satisfied with their service. Roger and Dario were very patient and answered all my questions. The roof is made by Storm and is one of the best poptop roofs I’ve seen. I highly recommend Cosmic Campervans to anyone looking for high-quality workmanship, I plan to use them in the future for a diesel heater. Their attention to detail and customer service is truly exceptional. Thank you, Karl.

Excellent service from the team at Cosmic Campervans. We opted for a Planar Diesel heater for our T5. Prices were very reasonable and availability to book the van in was good.The install quality was exceptional and Roger and the team took time to run through the system operation and a full demonstration.It’s easy to give good customer service when things go well but harder to do when there are problems. We had a few issues post install that were mostly down to a previous owners poor quality electrics. The team at Cosmic worked through them for us and made sure everything was as it should be and back to top quality. Cannot recommend these guys enough.Very knowledgeable, friendly team and seemingly nothing is too much trouble. They even make a good brew if you’re there for a bit while they check things over.For any future work I will be returning here as the guys are first rate.
