THROUGH THE WALL,
Easiest to install, least expensive (no HVAC contractor needed), simply install through an opening in the wall, which ideally, is adjacent to a mechanical room where the unit vents into. Plug into a 115 volt, dedicated 20 amp circuit and you’re ready to go. Rule of thumb, the area that it vents into has to be at least twice the size of the wine cellar or too much heat builds up, causing early failure of the unit. As with any refrigeration system, preparation of the space with proper vapor barrier and insulation is critical to the longevity of the system.
