  • Small Apartment Game Changer
Color: White
Living in a 500 sq ft studio, I have ZERO space for a bulky water heater tank. This unit is TINY (7.32 inches wide!) and mounts flush on the wall. The LED screen shows exact temp, and the touch button is easy to use. My water bill dropped because I'm not heating a whole tank. Obsessed!
