Eberspächer pre-heaters

Perfect thermal management in passenger cars

Fuel operated heaters

Eberspächer Hydronic S3 Economy

Since the Eberspächer Hydronic S3 Economy is integrated into the coolant circuit, it heats not only the passenger compartment but can simultaneously pre-heat the engine of suitable vehicles at standstill. It combines maximum comfort with stable heating performance and low fuel consumption. Even in the depths of winter, you enter a pleasantly warm vehicle and benefit from ice-free windows. The heating process is continuously monitored by highly sensitive sensors, and electronically controlled. The water circuit and the vehicle’s air ducts distribute the heat throughout the vehicle. 
On vehicle models with pre-heatable engines, starting is gentler on the engine, is less of a burden on the battery, consumes less fuel and so saves on emissions.
