814/2013 and 812/2013: Water heaters and hot water storage tanks

Last updated: 06 November 2019

The product group is under revision (website). Final revision reports was finalized July 2019.

Final ecodesign and labelling regulations for water heaters and hot water storage tanks entered into force in September 2013. 

A water heater is defined as a product connected to an external supply of drinking water to generate heat and transfer this water to desired temperature levels. The hot water is typically used for cooking, cleaning, bathing and space heating (and several items in industry).

The scope of the ecodesign regulation include:

  • Water heaters with a rated heat output ≤ 400 kW
  • Hot water storage tanks with a storage volume ≤ 2 000 litres.

Exceptions are, among others:

  • water heaters specifically designed for using predominantly biomass fuels;
  • water heaters using solid fuels;
  • water heaters designed for making hot drinks and/or food only;

For storage tanks, requirements for standing loss and product information are specified of Annex II, point 2.1.
