What is the Energy-related products (ErP) directive?
Directive 2009/125/EC of the European Parliament establishes a framework for defining the requirements of the Community for ecodesign of products, related to energy consumption. It contributes to the sustainable development by enhancing energy efficiency and the level of environmental protection, while improving the security of energy supply.
What does that mean?
Тhis is a program, introduced by the European Union, as means to reduce the energy consumption and carbon emissions in order to respond to the climate changes. How can a document help to reduce the impacts of climate change?
This is not just a document. This is The Document. By setting minimum requirements for energy efficiency, with this regulation all low–efficient heating appliances should be excluded from the market, while at the same time the other should be improved. The technical advancement of heating appliances leads to improved energy efficiency and therefore ensures decreased levels of energy consumption.
To which products does the new Eco-design regulation 2015/1188 apply?
Since 1 January 2018, the EU Commission has set the minimum requirements for the following CE labeled energy–related products:
• Electric panel heaters
• Electric water heaters
• Bathroom heaters
• Boilers
• Heat pumps with a rated heat output < 400 kW
• Renewable energy water heaters (solar,heat

How will the customer know what to choose?
Along with the Eco–Design directive, a directive for labeling the heating appliances has been adopted. All water heaters,
heat pumps and boilers need to be ranked from A (highest efficiency) to G (lowest efficiency). The other electric heating
appliances must reach the minimum ErP rating in order to meet the new standards.
What about the electric heating appliances?
The Eco–Design regulation is based on calculating the Seasonal Energy Efficiency (Ns) for every electric heating
appliance – convector, panel heater, radiator, radiant heater, bathroom heater. Each type of heater must meet the minimum
requirement, depending on the type of its installation – fixed or mobile. Those requirements are Ns=36% for mobile
appliances and Ns=38% for fixed appliances. The seasonal energy efficiency is calculated based on two criteria:
• Whether the device has a mechanical thermostat or an electronic thermostat + a weekly programmer
• Presence of advanced functions like adaptive start, control via Internet, open window detection. Gathering all functions, it reaches the maximum value of 40% Seasonal Energy Efficiency.

How does TESY respond to the new regulation?
As an innovative company, TESY welcomes the idea.
