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.

Are 'heavy duty' extension cords safe for space heaters?

Even heavy-duty extension cords are generally not rated for the sustained load of a space heater. The safest practice is always to plug the heater directly into a wall outlet.
