Answer from Myinfiniteinsights

Space heaters should always be plugged directly into a wall outlet. Using an extension cord or power strip can overload the circuit and create a fire hazard.

Portable space heaters draw a significant amount of electricity. Extension cords and power strips are not designed to handle this sustained electrical load, which can cause them to overheat and potentially start a fire. Always connect your space heater directly to a grounded wall outlet for safe operation.

Always follow the manufacturer's specific instructions for your space heater model.

What happens if I plug a space heater into an extension cord?

Plugging a space heater into an extension cord can cause the cord to overheat due to the high, sustained power draw. This overheating can melt the cord's insulation and potentially ignite nearby materials, leading to a fire.
