Reply to comment by ZAFJB in eli5 How can these disel+electric heaters used indoors. I don't get it since it is literally burning fuel what happens to the fumes indoors? by madFromV
Yeah, that's because the engine can't handle that kind of heat. It's still the same principle of removing heat from combusted fuel. If there were no radiators in a car, the heat would stay in the exhaust and engine.
The point is combustion produces heat, and we can remove that heat without touching the fumes. It doesn't become exhaust until.we want to get rid of it
