HYDRONIC MII-8 Coolant Heater

Espar’s coolant heaters work independently of the engine and thus offer a double plus: pre-heating the vehicle’s passenger compartment and the engine. The heaters are integrated in the cooling system of the engine. The thermal energy gained is then distributed through the vehicle’s own heat exchanger as forced hot air and this heats the interior of the vehicle via existing air vents. The engine is warmed up with the residual heat in the cooling water.
