Espar Air Heaters

Espar Air heaters – Innovation, Quality and Durability

No matter if you need cabin heat in your RV or work truck, Espar heaters offer the perfect heating solution. Espar air heaters (also known as Eberspacher heaters) are engineered for users who require reliable, efficient heat in demanding conditions.
These diesel and gasoline-powered bunk heaters deliver consistent performance without idling the engine. Espar heaters save fuel, reduce emissions, comply with anti-idle regulations and most importantly - prolong your engine’s lifespan.

Versatile Cabin Heaters for a Wide Range of Applications

Eberspacher air heaters can be used for various applications. Starting from vans, trucks, semi-trucks, to heavy-duty machinery, cranes, boats, specialty vehicles, construction machinery, emergency vehicles, utility vehicles, off-highway applications and more.
For Freightliner, Kenworth, Peterbilt, Mack, International trucks and other trucking fleet operators , Eberspacher heaters are often a top choice. These heaters offer fuel and cost savings and proven reliability, allowing truckers to heat their cabins without idling their engines.

Choose the Fuel Type That Fits Your Setup

Most Espar heaters come in both diesel and gasoline versions, so you can match your unit to your vehicle’s fuel type. Popular picks like the Espar Airtronic D2L Diesel Heater or the Espar Airtronic B4L Gasoline Heater offer constant, adjustable heat even in freezing temperatures.
Espar Airtronic D2L Diesel Heater has an ideally compact size that allows this cab heater to be installed in cranes.

Reliable No-Idle Cabin Heating for Cold Weather and Off-Road Travel

Eberspacher / Espar air heaters deliver high heat output, low fuel consumption, minimal electrical draw and high altitude capabilities. Modern models like the Espar Airtronic M3 series provide improved efficiency, quieter operation, and smart controllers like the EasyStart Pro.
Espar heaters are also trusted by van owners, van converters, off-grid travelers, and RV enthusiasts across the US who recognize the value of a professional-grade heating system, especially one that performs reliably at high altitudes.

Complete Air Heater Kits and Standalone Units

We offer a complete range of Espar (Eberspächer) auxiliary heaters and fuel metering pump (FMP) combos. Choose from standalone units or full installation kits, including vehicle-specific kits tailored for easy setup.

FAQs

  • Are Eberspacher diesel heaters fuel efficient?
    Yes! Espar diesel heaters use a small amount of fuel, usually less than 0,13 gallons per hour (0.5 l/h) for a 6800 BTU heater. That makes them very efficient for off-grid heating.
  • Can I install a Webasto parking heater myself?
    Yes, installation is possible for experienced DIYers, but we strongly recommend professional installation to ensure safety, optimal performance, and compliance with manufacturer guidelines.
  • Are Eberspacher heaters reliable?
    Eberspacher (Espar) heaters are among the most reliable solutions when it comes to air or coolant heaters. Trusted by OEM manufacturers and the military, these heaters have a proven track record of unbeatable performance.
  • Are these heaters safe to use while sleeping?
    Yes, when installed correctly, Espar heaters are safe and include built-in safety features like flame monitoring and overheating protection. However, for added safety and peace of mind, we recommend installing a Carbon Monoxide detector and a smoke detector.
  • Do Espar heaters come with a warranty?
    Yes, all our Espar air heaters include a manufacturer-backed warranty. Details are listed on each product page.
  • Will Eberspacher heaters work at high altitudes?
    Yes, Eberspächer (Espar) heaters are designed to operate at high altitudes. Depending on the model, many units feature automatic altitude adjustment for elevations up to 18,000 feet (5,500 meters).
  • What is the difference between Eberspacher and Espar?
    The original brand is Eberspacher. The Espar brand was used a while ago, which is why people sometimes still refer to Eberspacher products by that name.
