The calculation is made considering the presence of the complete NOW system (smart thermostat and smart thermostatic valves) and an average heating use of 5 hours a day for 180 days a year. For homes over 300 square meters, the calculation is based on 300 square meters, the increase in size leads to an increase in potential energy savings. The cost of energy supply is updated to February 2022, and includes national taxes. According to a study by the University of Bergamo, the transition from traditional mechanical valves to the complete NOW system results in an energy saving of 27,30%. An additional 20% of energy savings is achieved through Green Mode, setting an Eco temperature of maximum 3°C lower than the Comfort temperature.
