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.
- Off-mode (Po): 0,5 W
