Every space heater has the potential to cause a fire if left unattended or turned on for too long. The Handy Heater is no exception. This model has the necessary safety features like overheating protection and a timer, so you can rest assured you are safe as long as you use your personal space heater within fire safety guidelines. If you suspect your Handy Heater isn’t working as it should, unplug it from the wall immediately and get in touch with Ontel customer service through their website.
