Chinese diesel heater power cut. A test to destruction? So, everyone says my Chinese diesel heater will go bad if the the power supply fails. I put it to the test, what will happen to my Chinese diesel heater if there is a power cut? should I have a battery back up for my Chinese diesel heater? Chinese diesel heater demonstrated.
