Hot air ovens are electrical devices which use dry heat to sterilize.They were originally developed by Pasteur. Generally, they use a thermostat to control the temperature. Their double walled insulation keeps the heat in and conserves energy, the inner layer being a poor conductor and outer layer being metallic.There is also an air filled space in between to aid insulation.
