Endless Summer Tabletop Electric Heater
If you are looking for a table top heater, the Endless Summer New Orleans Indoor/Outdoor Electric Tabletop Heater will heat up the immediate area around the table. It puts out 1200 watts of heat, which will heat up the surrounding area, and it works best when you are sitting at the table. This heater is modeled after a table lamp, so it will fit into most decors, and will technically heat up a 12 foot radius.
This heater weighs 12 pounds, stands a bit less than 3 feet tall, features a safety anti-tilt switch, and could be used in either an exterior or interior setting. This heater is best used for close gatherings at a patio table even with the reduced wattage rate. Covered by a one year warranty, this is the lowest wattage rated heater and therefore the most economical to use on this list.
