Control features and low power modes
Furthermore, the new regulation (EU) 2024/1103 (applies from the 1st of July 2025) requires the following control features to further increase energy efficiency:
- Electric storage LSH shall be equipped with electronic heat charge control with room and/or outdoor temperature feedback and fan-assisted heat output.
- Towel rails with a nominal heat output equal to or below 60 W (which do not have a minimum efficiency requirement) shall only be operable through a working time limitation with a maximum pre-set period of no longer than six hours.
The new requirements for low power modes are:
LSH with controls, and separate related controls, shall meet the following requirements:
- They shall have an off-mode or a standby mode or both. The power consumption in off-mode (Po) shall not exceed 0,50 W and the power consumption in standby mode (Psm) shall not exceed 0,50 W; as from 9 May 2027, the power consumption in off-mode shall not exceed 0,30 W
- If the standby mode includes the display of information or status, the power consumption of that mode shall not exceed 1,00 W
- If the standby mode provides for a connection to a network and provides networked standby as defined in Article 2, point (10) of Regulation (EU) 2023/826, the power consumption of this mode (Pnsm) shall not exceed 2,00 W; if the communication between the heat generator and the control is wireless or through powerline carrier the power consumption of this mode shall not exceed 3,00 W
- If they provide for an idle mode, the power consumption of the idle mode (Pidle) shall not exceed 1,00 W as average over 1 hour, except if the idle mode depends on the input from a network connection to automatically provide heat to the room, in which case the power consumption shall not exceed 3,00 W as average over 1 hour.
