Portable electric heated floor mats are typically placed at the entrance to offices and other buildings to prevent people from slipping by melting snow and ice. They can also be placed on the floor at a desk or workspace for personal comfort heating. These mats have a quiet internal heating element that's protected with a GFCI integrated in the power cord.

Portable electric baseboard heaters use convection heating and don't have moving parts, so they're quieter than most other types of heaters. Some heaters have an electric element that's encased in an oil-filled vessel to provide consistent heat, while others have elements encased in a metal sheath with aluminum fins to transfer heat. They are typically placed along the wall in office spaces to provide spot or supplementary heat.

Portable radiator-style electric office heaters have a heating element contained in an oil-filled radiator, so they provide more consistent warmth than most other types of electric heaters and give off residual heat even after the unit is shut off. These heaters work by convection to warm the air and don't have moving parts, so they're quieter than unit heaters. They take up little floor space and are typically placed in office spaces and reception areas. These heaters have tip-over switches, so they will shut off automatically in case they are accidentally knocked over.

Portable flat panel electric office heaters are typically placed under desks in offices and reception areas for personal comfort heating.
