Hitachi S Series Wall Air Conditioning - Heat Pump
Description
The Hitachi S series room air conditioner and heat pump is the most energy efficient model on the Market. Another major benefit of the S-Series is pipework lengths between the indoor and outdoor unit of at least 20 meters, providing installation flexibility. These systems will also work down to an outside air temperature of -20 degrees centigrade, lower than most other manufacturers.
These systems are expensive but if energy efficiency down to low temperatures in heating mode is your main criteria these units could be for you.
