You won't find anything better than this efficient, durable and noise-free forced-air heater. The PULSAIR™ is extremely popular for many reasons. First, it can be recessed or surface mounted with a surface adapter (optional). In addition, it can be mounted vertically or horizontally, directing the air flow upward or downward and to the right or to the left, respectively. Last, the slim-line PULSAIR™ can be recessed into a wall thickness of 2 in to 3 in. While it's a winning heating solution for the hallway and bathroom, it can also be installed in other parts of the house, such as the office or in commercial buildings. Its ni-chrome element provides instant heat. Available from 500 W to 2000 W, and from 120 V to 347 V, the PULSAIR™ is recognized and recommended by those in the know.
