The installation of an Endocube in each refrigerator will reduce your electricity usage in that device by up to 30% and most likely over 20%.
Most of the refrigerators installed in Ireland are running inefficiently. Expensive, power-hungry compressors are unnecessarily turned on/off according to the temperature of the air which fluctuates more often that the temperature of the food under refrigeration.
Once the Endocube has been installed and the fridge has been optimised, power savings are immediate and payback is typically achieved within 6-9 months. Thereafter, the savings are visible on your bottom line… there is no catch!
