Can the car water tank be used as a radiator to keep warm?

Yes, that's all right. You can add a simple radiator to DIY's house. Water heated by the heater and hot water from the pump enter the radiator through pipes. Blow it back with the radiator of the household fan, which is the hot air blown out. No, the heating is divided into electric heating and electric hot water, the DC heating battery is directly used with ordinary cars, and the water pipe enters the indoor air through the fan, so it doesn't matter.

Matters needing attention

The water radiator is good, because the car is designed as a water tank and depends on the cooling fan. This is called forced circulation, while domestic heating is a natural environment of natural circulation. The cooling efficiency is higher than that of domestic radiator water tank.

If the home is covered with earth for heating, you can use the water tank of the car to increase the heat dissipation area (such as two water tanks in series). Central heating is not allowed in residential buildings.
