Can I leave my Vornado MVH heater on all night?

While the Vornado MVH heater has safety features, it's generally not advisable to leave space heaters on unattended, including overnight. Although this specific model includes built-in safety mechanisms like automatic shut-off switches if tipped over, there are still risks involved with operating any heater for extended periods. For instance, if the heater is placed too close to combustible materials like curtains or bedding, this can pose a fire hazard. Pro Tip: Always place the heater at least three feet away from any flammable objects. Consideration should also be given to personal safety; if you or your family members are prone to allergies or respiratory issues, heat can stir up dust and other allergens while you sleep.
