Electric heaters made by Vornado, Lasko, Stadler, NewAir and Duraflame are considered some of the safest electric heaters available. These heaters integrate multiple safety devices to prevent overheating, fires and burns.
Several of these heaters integrate tip-over sensors that shut the heater off if they detect it has been knocked over. This helps prevent a heater from tipping into an object or the floor and causing it to catch fire. These heaters also feature overheating detectors that shut the heater down if it becomes too hot. Models from Vornado and Duraflame also feature cool-touch exteriors, as they are designed without exposed heating elements and do not need hot surfaces to function.
