Eberspacher Espar Hydronic II D5S Economy 12v Water / Coolant Heater

This heater has advantage of pre-heating the engine as well as the passenger compartment. It uses the car's own water system with heat exchanger and fan. Hydronic II D5S can be fitted in any type of car.

This is the second generation Hydronic heater (the most recent, 3rd generation heater can be found here). The main differences from the older Hydronic 5 versions - improved fuel efficiency, works faster and it is more reliable than its predecessors. It also works with the new type Easysart controllers / timers / GSM System.
