However, their heat retention capabilities mean they don't constantly draw power, unlike some other types of heaters. Expect to pay a bit more up front for better build quality, which translates to fewer headaches down the line.
Always inspect the power cord for damage and ensure the heater is placed on a level surface. Keep it away from flammable materials.
