A compact, quiet and economical heater.

 The Eberspacher D4S heater is a slightly de-rated version of the ever-popular Eberspacher D4 heater. Slightly reduced heat output and careful reworking of blower motor speeds allows this heater to be utilise 75mm ID ducting rather than 90mm ID ducting. This configuration is ideal for the larger RV motorhome  where higher heat outputs are required but compactness and space are still at a premium. The Eberspacher D4S Airtronic offers optimized fuel efficiency, a range of operation modes and unsurpassed safety standards. Programmable independent heating (does not use heat from the engine) for all types of road vehicle use. Certified for installation in passenger areas and in proximity to dangerous substances.

Please Note -  When above timer upgrade is chosen from this listing, the standard controller pictured will be removed from the kit (if applicable).
