The issue for a heavy use street car in that case is there is nothing extracting heat from the water. It’s no issue for casual driving where the car is moving more than stopping and going, or running down a drag strip.

Even for casual driving, the water will heat up without the HE. I can understand a strip car that gets iced down for every run. But, without a HE, how does the water shed its heat?
