(RU2120057-C1)      The pre-heater for a water-cooled IC engine with an external heating system for the car which is independent of the engine, uses a common water circuit. There is a temperature monitor which automatically sets the heating system into motion when the temperature falls below a limit, the system heating the car and the engine in parallel flow circuits. If required, a third parallel circuit for battery heating can be switched in. There is a manual override.    The monitor is a thermoelectric element with a direct connection to the circulating pump. In an alternative design, the three heating circuits are activated sequentially from a central control unit.    ADVANTAGE -   Simple, compact and reliable even down to outside temperatures of -60 degrees Centigrade.
