Electric heaters (local space heaters) entering the EU market: ErP compliance is not a single "certificate" acquisition activity, but a technical compliance system built on two legal pillars – the Ecodesign Regulation (EU) 2024/1103 (replacing the former 2015/1188) and the Energy Labelling Regulation (EU) 2015/1186.
Its core logic is: first complete energy efficiency testing and calculation in accordance with harmonised standards, then compile technical documentation based on the test data, subsequently complete energy label registration in the EPREL database, and finally assume legal responsibility for product compliance in the form of the CE mark.
I. Why Electric Heater ErP Compliance Is a "Must‑Answer Question" Rather Than a "Multiple Choice"
The implementing regulations under the ErP Directive (2009/125/EC) set mandatory ecodesign requirements for local space heaters, which together with LVD and EMC constitute the regulatory elements of CE certification.
(EU) 2024/1103, published in April 2024, has replaced the former (EU) 2015/1188, imposing more detailed requirements on low‑power modes, control functions, and repairability for electric local space heaters.
Non‑compliant products face risks of import obstruction, platform delisting, and fines of up to over EUR 100,000.
II. Analysis of the Electric Heater Regulatory Framework: The "Dual‑Track System" of ErP Ecodesign and Energy Labelling
Clarify the division of labour between the two regulations: The Ecodesign Regulation governs "whether the product can be sold" (minimum energy efficiency thresholds, functional requirements); the Energy Labelling Regulation governs "how to inform consumers" (label class, product information sheet). The two operate in parallel and must not be confused.
Clarify the scope of application: Electric heaters correspond to "electric local space heater" in the regulations, covering sub‑categories such as portable, fixed, storage, and visibly glowing radiant types. Note: products used solely for drying towels with extremely low heat output have special exemptions or simplified requirements, but the criteria for determination are strict.
Key update reminder: The new regulation reduces the primary energy conversion coefficient (CC) from 2.5 to 1.9, directly affecting the calculation results of seasonal space heating efficiency for electric heaters. If exporters continue to use the old coefficient, test reports will become invalid.
III. Four‑Step ErP Certification Compliance Process for Electric Heaters: From Testing to Label Registration
Step 1: Determine the applicable implementing regulation and harmonised standards
Confirm that the product falls within the scope of (EU) 2024/1103 (electric local space heaters).
Testing should prioritise harmonised standards published in the Official Journal of the EU; where standards are lacking, the Commission‘s transitional calculation methods shall be followed.
Step 2: Complete energy efficiency testing and seasonal efficiency calculation
The seasonal space heating efficiency calculation formula for electric local space heaters is: η_s = η_s,on / CC, where CC = 1.9.
Measure on‑mode efficiency and standby/off‑mode power consumption (the new regulation requires off‑mode power consumption ≤0.50 W, tightened to ≤0.30 W from May 2027).
If the product is equipped with a thermostat or network functionality, the applicability of correction factors F(2) and F(3) must be accurately assessed and must not be falsely declared.
Step 3: Compile technical documentation and Declaration of Conformity
Technical documentation must include: product description, list of equivalent models, test reports, energy efficiency calculation process, and key component list.
Conformity assessment may use the "internal design control" mode, but the technical documentation must demonstrate that the product meets regulatory limits.
Step 4: EPREL registration and label upload
Complete product registration in the EU EPREL database and generate the new energy label (A‑G class; the old A+++ to D scale has been abolished).
In e‑commerce sales scenarios, the colour energy label image and product information sheet must be displayed simultaneously on the product page, usually in JPG format.
IV. High‑Frequency Pitfalls and Compliance Red Lines in Electric Heater ErP Certification
Pitfall 1: Control function "hardware present but not declared". If the manufacturer claims that the product has room temperature feedback control to obtain efficiency bonuses, that control device must be provided within the same product (it may be external but must be supplied with the product), and the manual must clearly state the installation method. Otherwise, market surveillance authorities may determine that the bonus is invalid.
Pitfall 2: Ambiguous characterisation of towel rail products. Low‑heat‑output towel rails used solely for drying as the primary purpose with heat output ≤60 W need only meet working time restriction requirements; however, if they are claimed to also have space heating functions, they must fully comply with ecodesign energy efficiency requirements.
Pitfall 3: Technical documentation retention period. Technical documentation and the Declaration of Conformity must be retained for 10 years from the date the product is last placed on the market, for traceability by market surveillance authorities.
V. The Endpoint of Electric Heater ErP Compliance Is "Sustainable Market Access"
ErP compliance is not a one‑off transaction but part of product lifecycle management. The repairability requirements and spare parts supply obligations introduced by the new regulation mean that companies need to bring compliance thinking forward to the design stage.
Before export, verify that the regulation version and CC coefficient cited in the test report are consistent with the currently effective regulations; EPREL registration information must strictly correspond to actual test data to avoid delisting triggered by "data drift".
In the context of increasingly tightened EU energy efficiency regulation, compliance capability itself is becoming the core competitiveness of electric heater exporters.
