Abstract
A portable heater operates at a first power rating to rapidly heat a space and a second power rating, lower than the first, to safely maintain the temperature of the space. The heater uses a first resistive heating element and a second resistive heating element which are configured to automatically supply the first power rating during an initial heating period then step down to the second power rating for continuous operation.
