Overview

prEN IEC 60335-2-73:2026/prAA:2026 is a draft European standard developed by CLC (European Committee for Electrotechnical Standardization), detailing the particular safety requirements for fixed immersion heaters used in household and similar environments. These electric thermal-storage room heaters are designed to heat the room where they are installed, operating at voltages not exceeding 250 V for single phase and 480 V for other appliances.

This draft amendment specifically modifies and supplements the European standard prEN IEC 60335-2-73:2026, integrating updates that enhance the safety measures and usage instructions for these appliances. The document covers foreseeable hazards associated with the operation of fixed immersion heaters and emphasizes accessibility and safety for all users, including children, people with disabilities, and domestic animals.

Key Topics

  • Hazard Prevention: The standard addresses reasonably foreseeable risks associated with fixed immersion heaters in the household and similar environments, promoting user safety.
  • Applicability: It clarifies that its requirements apply to all persons and domestic animals who may interact with these appliances.
  • Instructions and Marking: Enhanced guidance is provided to ensure that safety instructions are clear and comprehensive, particularly for vulnerable users.
    • Specific requirements include supervision of children (especially those under 8 years), and clear limits on user maintenance roles.
  • Voltage and Type: Applies to heaters with rated voltages up to 250 V (single phase) and 480 V (other appliances).
  • Routine Testing: Excludes routine test requirements, focusing instead on installation and operational safety.
  • Integration with Other Standards: Must be applied alongside EN IEC 60335-1:2023, the general standard for the safety of household and similar electrical appliances.

Applications

Fixed immersion heaters regulated by this standard are primarily used for heating spaces in domestic and similar environments, including:

  • Residential homes
  • Apartments and flats
  • Schools, offices, and similar public buildings
  • Care facilities, where enhanced guidance for vulnerable persons is particularly relevant

By ensuring compliance, manufacturers and installers help guarantee that immersion heaters are safe for widespread usage, aligning with EU safety directives and enhancing consumer confidence. The standard also applies to appliances incorporating features such as remote operation and radio communication, reflecting modern usage scenarios.

Related Standards

For comprehensive compliance and implementation, the following standards are relevant to prEN IEC 60335-2-73:2026/prAA:2026:

  • EN IEC 60335-1:2023 - General requirements for the safety of household and similar electrical appliances
  • IEC 60335-2-15 - Particular requirements for water boilers
  • IEC 60335-2-21 - Particular requirements for storage water heaters
  • IEC 60335-2-35 - Particular requirements for instantaneous water heaters
  • IEC 60335-2-55 - Particular requirements for electrical appliances for heating liquids
