Whynter ARC-147WFH Air Conditioner and Heater

The dual-hose system is significantly more efficient because it uses one hose to intake fresh air for cooling and a second hose to exhaust hot air. This prevents the unit from creating negative air pressure in your room, which often pulls hot, humid air from outside or adjacent rooms into your living space.

Yes, it features an 8,200 BTU heating function that works well for supplemental heating in spaces up to 500 square feet. It is designed to take the chill out of a room rather than replace a primary central heating system.
