Core Features & Benefits
Espar / Eberspacher Hydronic D4WSC Heater 12v
The Eberspacher Hydronic D4WSC heater comes with an Eberspacher D4WSC manual. This powerful compact heater will reliably warm the passenger area and engine bay.
This heater is mainly used as a replacement for older systems. If you want to install a new system, we suggest you consider the new generation Hydronic Heater, like Hydronic II D5S.
Not even open the box, was bought as a back unit for one already installed and rebuilt a few months ago.

The new unit would not fit the 2003 base. Had to modify things. Would have nice if that possibility had been brought up when I bought the replacement unit
