Eberspacher heater kits are complete diesel-powered heating solutions designed for campervans, motorhomes, and marine applications. These German-engineered systems provide independent heating without running your vehicle's engine, offering 2.2kW heat output with fuel consumption as low as 0.06 litres per hour. The kits typically include the Airtronic heater unit, EasyStart Pro digital controller, mounting hardware, ducting, exhaust components, and installation accessories. The new D2L model is approximately 90% quieter than previous versions and features a brushless motor providing 5000 hours service life.
Professional installation by qualified engineers is mandatory to maintain warranty coverage and comply with safety regulations. Your Eberspacher heater must be installed by a suitably qualified engineer in compliance with all industry application and safety regulations. The systems operate in extreme conditions, functioning at temperatures as low as -40°C and altitudes up to 3,000 metres with automatic altitude adjustment. Popular applications include VW Transporters, Mercedes Sprinters, and Ford Transits, with specific mounting plates available for different vehicle models.
While these heaters offer exceptional reliability and German engineering quality, one consideration is the initial investment cost compared to cheaper Chinese alternatives. However, the superior build quality, extensive dealer network, genuine parts availability, and comprehensive warranty support make Eberspacher kits the preferred choice for serious outdoor enthusiasts. Authorised dealers typically provide a 3-year limited parts and labour warranty, with annual servicing required to maintain coverage.

Frequently Asked Questions
Do Eberspacher heater kits include everything needed for installation?Yes, complete Eberspacher heater kits include the heater unit, EasyStart Pro controller, mounting hardware, ducting, exhaust components, fuel pump, wiring harness, and all necessary fittings. Vehicle-specific mounting plates are included for popular models like VW Transporters, Mercedes Sprinters, and Ford Transits. However, professional installation by qualified engineers is mandatory to maintain warranty coverage.Why must Eberspacher heaters be professionally installed?Professional installation is required for safety compliance, warranty validity, and proper combustion air and exhaust routing. Qualified engineers ensure correct fuel line connections, electrical wiring, and carbon monoxide safety measures. DIY installation voids the 3-year warranty and poses serious safety risks including potential carbon monoxide poisoning. Annual servicing by accredited agents is also required to maintain warranty coverage.How fuel efficient are Eberspacher diesel heaters compared to gas heating?Eberspacher D2L heaters consume between 0.06-0.28 litres of diesel per hour depending on heat output settings. This provides significant fuel savings over gas heating, especially during winter camping when 80% of gas consumption typically goes to heating. The heaters run directly from your vehicle's fuel tank, eliminating the need to carry heavy gas bottles and reducing weight while increasing storage space.What's the difference between Airtronic AS2 and newer AS3 models?The AS3 D2L is the latest third-generation model featuring improved plug-and-play installation, integrated altitude sensors up to 4,000m, and enhanced fuel efficiency. It maintains the same 2.2kW output and 5,000-hour service life as the AS2 but offers better diagnostics, quieter operation with dampened fuel pump, and simplified wiring. The AS3 is compatible with existing EasyStart controllers while providing more accurate fault detection.Can Eberspacher heaters operate at high altitudes and extreme temperatures?Yes, Eberspacher heaters function reliably at temperatures as low as -40°C and altitudes up to 3,000 metres (9,900 feet) with newer AS3 models rated to 4,000 metres (13,120 feet). The integrated barometric pressure sensor automatically adjusts combustion parameters for optimal performance at altitude. This makes them ideal for mountain touring and winter camping in extreme conditions where other heating systems may fail.How long do Eberspacher heaters last and what maintenance is required?Modern Eberspacher D2L heaters feature brushless motors rated for 5,000 hours of operation compared to 3,000 hours on older models. Annual servicing by accredited Eberspacher agents is required to maintain the 3-year warranty beyond the first year. Regular maintenance involves cleaning the combustion chamber, checking fuel pump operation, and inspecting exhaust components. With proper care, these heaters typically provide 10-15 years of reliable service.
