The Envi Plug-in Electric Panel Wall Heater is a 500-watt convection heater designed for silent, energy-efficient zone heating in small indoor spaces up to 150 square feet.

The Dr. Infrared Heater DR-988 is a powerful industrial forced-air heater designed for large, drafty spaces like garages and workshops. It delivers rapid heat with high BTU output but requires a dedicated 240V/30A electrical outlet, limiting its residential applicability. It is best suited for contractors and DIYers with access to high-voltage power.
