What´s behind Eco Design

European Directive helps reducing energy consumption with electric radiators and provides further consumer benefits

From 1st January 2018, all electric local space heaters manufactured for sale in the EU must comply with a minimum efficiency standard under Lot 20 of the Energy Efficiency Directive.

Electric space heaters are considered energy-related products that have a considerable energy-saving potential.

The Eco Design Directive forms the European legal framework for setting requirements for environmentally friendly design of energy-related products.

The aim of this legislation is to rule out inefficient technologies and reduce the energy used by the products that heat our homes, helping to achieve carbon reduction targets.

The Regulation affects the following

  • Electric Room Heating Radiators
  • Storage heaters
  • Direct acting heaters
  • Portable heaters
  • Radiant heaters
  • Electric fires

How to achive the legal requirements?

This guideline is reducing environmental impacts taking into account the entire product life cycle.

Compliance with the guideline is based on a points system rating.

Various features and functions can contribute to achieve the minimum legal requirements, for example:


  • Low energy consumption of ≤ 0.5 Watts in stand-by mode for increased energy efficiency
  • Individual daily and weekly programs for comfortable and user-friendly operation
  • Timer function allows needs-based operation
  • Innovative "window open detection" guaranteed energy-efficient and comfortable heating
  • Flexible control options with radio control unit and / or App control for smartphone

Open window detection

The integrated control unit recognises the if a window has been opened for an extendend period and switches the radiator off.

Once the window is closed, the radiator returns to normal operation.

  • External temperature sensor recognises temperature changes
  • Integral thermostat reacts to sensor information
  • Radiator automatically switches off if a window is open for an extended period
  • Intelligent heating that saves energy and costs

Installation benefits

Installing heating pipes comes with much effort and costs. 

Furthermore, renovating a home, installing traditional heating pipes is often not possible or economically not viable. 

With a socket nearby, an electric radiator can be hung wherever you want, and the wireless control placed within easy reach. 

Zehnder sees the new guideline as confirmation of the continuous further development of its products, which not only meet standards, but also exceed them. 

Electric radiators saving costs and producing less power wastage combined with highest expectations on design and innovation, you can find in our wide range of electric designer radiators and towel warmers.
