Ventless fireplace vs infrared heater: infrared describes how heat moves, not what burns. Three different appliances get confused here. Only one combusts.
Ventless fireplace vs space heater: the plug-in heater’s documented harm is fire, the gas unit’s is what it adds to your indoor air. An honest comparison.
Ventless fireplace vs pellet stove: one vents outside and needs electricity, the other keeps its exhaust in the room. Which constraint can you live with?
