The 5 Best Space Heaters for Large Rooms

A space heater cannot make a poorly insulated room efficient by promising a bigger square-foot number. Most plug-in models here top out around 1,500 watts; the difference is how they move warmth, where you can safely place them and how conveniently the thermostat controls a cold corner. Measure the circuit load before adding one to a room that already has high-draw appliances.

I would start with Lasko's tall ceramic tower for a living-room seating area because oscillation and a remote are practical when the heater sits across the room. Dr Infrared is a heavier, cabinet-style alternative. The smaller Dreo units cost less and are easier to move, but I would choose them for a defined sitting zone rather than expect one to solve the entire house.
