Control features and low power modes

Furthermore, the new regulation (EU) 2024/1103 (in effect since 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 6 hours. 

The new requirements for low power modes of LSH with controls, and separate related controls are:

  • Such LSH shall have an off-mode or a standby mode or both.
  • Max. power consumption:
    • Off-mode (Po): 0,5 W
      From May 9th, 2027: 0,3 W
    • Standby mode (Psm): 0,5 W
    • Standby mode incl. display of information or status: 1 W
    • Standby mode providing connection to the network and networked standby  
      (i.e. LSH can resume a function by a remotely initiated trigger from a network connection): 2 W
    • Standby mode with wireless communication between the heat generator and control or by powerline carrier: 3 W
    • If existent: Idle mode (Pidle) (average over 1 hour):
      • 1 W
      • If idle mode depends on the input from a network connection to automatically provide heat to the room: 3 W.
