Because of the unit's efficiency, there is a much lower level of heat emitted when compared to a conventional unit. The temperature of the unit is so low that you can actually rest your hand on the unit as it operates.
The lower temperature creates two unique advantages for the manufacturer. The first being that all associated component and sealing parts wear is minimised, leading to less breakdown and increased durability. Second, the overall footprint of the packaged unit is significantly smaller in size, promoting increased adaptability within installation.
