Eberspacher are one of the market leaders in automotive heating systems. At the forefront of Eberspacher’s heating portfolio is the Eberspacher Airtronic heater range, consisting of the Eberspacher Airtronic D2, D4, D4S and D5. The Airtronic D2 is a compact but efficient air heater with a 2kw heat output, perfect for Campervans, smaller Motorhomes and the extremely popular VW Volkswagen T5. The Eberspacher Airtronic D4 is a 4kw heater usually installed in larger motorhomes with three heat outlets for optimum performance. The Airtronic D4S or D4 Plus features a smaller ducting diameter for ease of installation and with its 3.5kw heat output is becoming increasingly popular when trying to find that middle ground between space and heat.
