Heat it up
While it’s important to dust off and clean heater grills, it’s also important to check that appliances, especially those that have been in storage for a while, are in good working order.
Check cables, plugs and the unit itself to make sure it is undamaged. Cables shouldn’t be stored twisted and bent because it can cause damage to the wires inside, as the wires degenerate over time, it can cause arcing, which are one of the most common causes of house fires.
For peace of mind, talk to your electrician about installing the right kind of protection in your switchboard. Arc Fault Detection Devices (AFDDs) are a really good addition to any home as they detect arc flashes and shuts down the circuit to help prevent fires.
