The REOS HOME under-counter reverse osmosis system is very energy efficient and uses very little power. The system's power supply has a maximum output of 38 watts.
To better understand the power consumption during operation, here are some details:
Average power consumption: If the system is in operation for 1 hour per day, it consumes 38 watts per hour.
Annual power consumption: With a usage of 1 hour per day (which is generously calculated for a water filter system) the following annual power consumption results:
Daily consumption: 38 watts * 1 hour = 38 watt hours (Wh) per day
Annual consumption: 38 Wh * 365 days = 13,870 Wh = 13.87 kilowatt hours (kWh) per year
With an average electricity price of 0.30 euros per kWh, the annual electricity costs would be around 4.16 euros.
This shows that the system is extremely energy efficient and cost-effective to operate, even with regular use.
