The warmth from the engine goes from the radiator to the heater core, which basically acts as a heat exchanger. It allows coolant to flow through, and this flow of coolant is regulated by the heater control valve. As the engine's heat is carried by coolant into the heater core, the device starts to get warm.
How does a car heater work?
How Your Car’s Heater Works. Commonly, the thermostat opens at 165 to 195 degrees. As coolant begins to flow through the engine, heat from the engine is absorbed into the antifreeze and carried through to the heater core. The "heater core" is a heat exchanger much like a radiator. It is mounted inside the heater housing inside your car’s dash.

How does a car engine coolant system work?
Once the engine reaches its operating temperature, the thermostat opens up to allow the flow of “hot” coolant into the radiator. This allows it to dissipate the heat and to bring down the temperature of the coolant. After this, the coolant recirculates to the engine. Try to imagine an engine without a thermostat.
How does a petrol car heat the air?
If necessary, the air may be warmed further by an electrically ignited petrol-burning heat exchanger. The heat exchanger also allows the heater to work with the engine off -unlike a water-heated type. The rest of the system, the way in which the heat is distributed, is like that of any other car.
