EcoDesign Lot 20 Compliancy - Electrical Heating

If you’re passionate about electrical efficiency, then you are probably aware of what Lot 20 is. If you’re not so passionate about it, then you’re probably a 'normal' person and this post will hopefully explain a few things about this new regulation.

What is EcoDesign Lot 20?

EcoDesign Lot 20 is an EU regulation that means that all local space heaters sold within the EU must meet a certain level of efficiency. This regulation came into effect on 1 January 2018. Local space heaters are defined asappliances that provide heat to indoor spaces by generating heat at the same location as it is needed”. It covers more than just electric radiators. The actual quote from the EU regulation is:

“All local space heaters manufactured for sale in the EU after 1st January 2018 which use electricity, gaseous or liquid fuels, must comply with a minimum efficiency standard. This includes electric radiators, electric underfloor heating and electric and gas fires.”

It may seem to include an awful lot, but it doesn’t cover everything. For instance, it does not include towel rail heaters. We sell a lot of electric heating products here at Juice Electrical Supplies, and we are proud that all of them meet Lot 20:

How does it ensure efficiency?

This new regulation will ensure efficiency by ensuring that all heaters sold in the EU come with intelligent room temperature controls to minimise wasted energy. Intelligent room temperature controls make it so that your heater will not use up electricity unnecessarily. It includes a number of features:

  • 24/7 timer control (optional smartphone WiFi control).
  • Accurate thermostat to measure temperature and offer precise control.
  • Open window tech to make sure that electricity isn’t wasted heating a room with a window open.

Electric radiators, infrared heaters and panel heaters that output at least 250W all need to reach 38% energy efficiency to be compliant. Smaller and portable heaters will have different energy efficiency requirements.


Why was it introduced?

Inefficient heating is both a waste of money for homeowners and does unnecessary damage to the environment. The EU Commission decided that electrical heating had room for improvement when it came to efficiency. Heating is a larger part of the energy we use to heat our homes. In a government survey, 30% of UK homeowners were worried about their heating bills, so it’s no surprise that energy efficiency is something to be strived for.


Lot 20 also requires certain information to be displayed when selling heaters both online and in-store:

  • Heat output
  • Auxiliary electricity consumption
  • Temperature control type  - F2 compliance type
  • Additional features - F3 compliance type(s)

Will Brexit affect it?

Brexit seems to affect everything, but does it affect Lot 20? No, actually. Brexit means that we are leaving the EU (at least, at the moment that’s our path), however this does not affect EcoDesign Lot 20, because we already signed up to it, so we are bound to carry it out. On top of that, it has come into effect even before we have left the EU. Even outside the EU, the UK will still want to adhere to a high-standard of energy efficiency for its heaters.


The drive towards energy efficiency can only be a good thing. Forcing companies to comply with this will spur them on to develop the technology and make energy efficiency heaters cheaper. What this means for you is that the market will now only have energy-efficient heaters, so whatever you buy, it will ensure that you are making the most of your energy.
