      <p>If you import, distribute or private-label electric heaters into the EU, the clock is ticking. <strong>Regulation (EU) 2024/1108</strong> — the so-called “ERP Lot 2” ecodesign rule for local space heaters — comes into full force on <strong>1 January 2027</strong>. From that date, any heater sold in the EU market must meet new seasonal-space-heating efficiency (η<sub>s</sub>) limits, new maximum standby power, and stricter product information requirements. This article gives you the timeline, the numbers, and a 7-point SKU audit checklist so you can act in time.</p>
<blockquote>
<p><strong>WHO SHOULD READ THIS</strong> — Distributors, importers, private-label brand owners and OEM sourcing managers selling or planning to sell electric convection heaters, oil-filled radiators, infrared heaters, fan heaters and radiant panels into the EU 27 member states.</p>

<h2 id="30-second-summary" tabindex="-1"><a class="header-anchor" href="#30-second-summary">30-second summary</a></h2>
<p>Here is what you need to remember — even if you read nothing else in this article:</p>
<ul>
<li><strong>Effective date:</strong> 1 January 2027 (no grace period for new stock).</li>
<li><strong>Key metric:</strong> seasonal space heating efficiency (η<sub>s</sub>), measured under EN 60675:1997 + EN 60675/A1:2015.</li>
<li><strong>Heater classes that change:</strong> all “local space heaters” except air-curtains, floor heating and high-temperature radiant heaters.</li>
<li><strong>New requirements:</strong> η<sub>s</sub> minimum 38% for fixed heaters, 32% for portable, plus ≤0.5 W standby power.</li>
<li><strong>Documentation:</strong> technical file + product fiche + label per regulation (EU) 2024/1108 Annex II.</li>
<li><strong>Enforcement:</strong> national market surveillance authorities (e.g. BNetzA in Germany, DGCCRF in France, ACAE in Spain).</li>
</ul>
<h2 id="full-timeline" tabindex="-1"><a class="header-anchor" href="#full-timeline">Full timeline</a></h2>
<p>Regulation (EU) 2024/1108 was published in the Official Journal on 18 April 2024 and entered into force 20 days later. Here is the timeline that actually matters for B2B heating importers:</p>
<table>
<thead>

<blockquote>
<p><strong>CRITICAL: NO “SELL-THROUGH” PERIOD</strong> — Unlike previous ecodesign lots, Regulation (EU) 2024/1108 does <strong>not</strong> provide a sell-through period. After 1 January 2027, you cannot place non-compliant heaters on the EU market — even if you bought them in 2026. Stock held in EU warehouses is also affected once relabelled or re-marketed.</p>

<h2 id="%CE%B7s-efficiency-thresholds" tabindex="-1"><a class="header-anchor" href="#%CE%B7s-efficiency-thresholds">η<sub>s</sub> efficiency thresholds</a></h2>
<p>The seasonal space heating efficiency (η<sub>s</sub>) replaces the older “nominal heat output” approach. It is a weighted average that takes into account cycling losses, standby consumption, and off-mode power. Here are the minimum thresholds that apply to the most common electric heater categories:</p>
<table>

<th>Heater category</th>
<th>Min η<sub>s</sub> (2027)</th>
<th>Min η<sub>s</sub> (2030, indicative)</th>

<p><strong>GOOD NEWS FOR SMART-HEATER BRANDS</strong> — Heaters with adaptive start, open-window detection, and WiFi scheduling typically score 4-7 percentage points higher on η<sub>s</sub> than basic mechanical models. If you’re already selling a smart SKU, the Lot 2 transition is essentially free.</p>
</blockquote>
<h2 id="what-products-are-in-scope" tabindex="-1"><a class="header-anchor" href="#what-products-are-in-scope">What products are in scope</a></h2>
<p>Article 2 of the regulation defines the scope. Local space heaters covered include:</p>
<ul>
<li>Electric convection heaters (fixed and portable)</li>
<li>Oil-filled radiators</li>
<li>Infrared heaters (indoor use)</li>
<li>Fan heaters (≤ 50 kW)</li>
<li>Radiant panels and ceiling-mounted heaters</li>
<li>Storage heaters with direct heat emission</li>
</ul>
<p>Excluded products (you can keep selling these without Lot 2):</p>
<ul>
<li>Floor heating (embedded in floor construction)</li>
<li>Air curtains</li>
<li>High-temperature radiant heaters (mostly industrial)</li>
<li>Outdoor-rated heaters (IP × 5 or above, “outdoor use only” label)</li>
</ul>
<h2 id="sku-audit-checklist" tabindex="-1"><a class="header-anchor" href="#sku-audit-checklist">SKU audit checklist</a></h2>
<p>Before you contact your factory, run every active SKU through this 7-point checklist. If any SKU fails 2 or more points, plan a replacement or relabelling exercise now.</p>
<ol>
<li><strong>Do you have a current EN 60675 test report?</strong> Older reports (pre-2015) do not measure η<sub>s</sub>.</li>
<li><strong>Standby consumption ≤ 0.5 W?</strong> Many mechanical thermostat heaters draw 1-3 W in standby — non-compliant out of the box.</li>
<li><strong>Product fiche + label designed per Annex II?</strong> Format differs from old ERP Lot 20 fiches.</li>
<li><strong>Technical file includes ecodesign compliance evidence?</strong> Notified body test certificate must reference (EU) 2024/1108.</li>
<li><strong>Open-window detection or adaptive start present?</strong> Required for the “+2%” bonus on η<sub>s</sub>.</li>
<li><strong>Packaging declares heating season efficiency?</strong> Required for all retail packaging ≥ 50 W.</li>
<li><strong>WiFi/IoT variant uses EU data-residency?</strong> GDPR enforcement is parallel and unforgiving.</li>
</ol>
<h2 id="how-hearthcore-oem-heaters-comply" tabindex="-1"><a class="header-anchor" href="#how-hearthcore-oem-heaters-comply">How Hearthcore OEM heaters comply</a></h2>
<p>Every Hearthcore heater shipped to an EU customer since January 2025 has been built to the Lot 2 framework. Here’s what that means in practice:</p>
<ul>
<li><strong>η<sub>s</sub> tested under EN 60675:1997/A1:2015</strong> at our partner lab TÜV Rheinland (report available).</li>
<li><strong>0.3 W standby</strong> on all 2025+ control boards (below the 0.5 W ceiling).</li>
<li><strong>Adaptive start + open-window detection</strong> standard on every convection and radiator SKU.</li>
<li><strong>Product fiche and label</strong> pre-generated per SKU in English, German, French, Spanish — drop-in for your retail packaging.</li>
<li><strong>CE technical file</strong> assembled per Annex IV — yours to keep, audit-ready.</li>
</ul>
<p>For OEM/private-label customers, we additionally pre-fill the EU compliance section of your <code>technical_dossier.zip</code>, which typically saves 4-6 weeks of internal compliance work.</p>
<h2 id="frequently-asked-questions" tabindex="-1"><a class="header-anchor" href="#frequently-asked-questions">Frequently asked questions</a></h2>
<h3 id="do-i-need-to-retest-heaters-that-already-have-a-ce-mark%3F" tabindex="-1"><a class="header-anchor" href="#do-i-need-to-retest-heaters-that-already-have-a-ce-mark%3F">Do I need to retest heaters that already have a CE mark?</a></h3>
<p>Yes. The CE mark under the old Low Voltage Directive (LVD) does not cover ecodesign. You need a new test report under EN 60675/A1:2015 from a notified body. We can coordinate this for OEM customers as part of the order — typically 14-21 days.</p>
<h3 id="what-about-uk-after-brexit%3F" tabindex="-1"><a class="header-anchor" href="#what-about-uk-after-brexit%3F">What about UK after Brexit?</a></h3>
<p>The UK has its own ecodesign framework (UK Ecodesign for Energy-Related Products Regulations 2024) which largely mirrors the EU Lot 2 thresholds but uses UKCA marking and a separate technical file. See our <a href="/blog/ukca-vs-ce-after-brexit-labeling-guide/">UKCA vs CE labeling guide</a>.</p>
<h3 id="will-this-affect-my-2026-orders%3F" tabindex="-1"><a class="header-anchor" href="#will-this-affect-my-2026-orders%3F">Will this affect my 2026 orders?</a></h3>
<p>Orders shipped before 31 December 2026 can still be placed on the EU market — but the <em>stock</em> after that date must be compliant. If you’re planning to warehouse heaters for the 2027/28 season, specify Lot 2 compliance in your PO now to avoid stranded inventory.</p>
<h3 id="how-long-does-compliance-cost-take%3F" tabindex="-1"><a class="header-anchor" href="#how-long-does-compliance-cost-take%3F">How long does compliance cost take?</a></h3>
<p>For an existing SKU: 4-6 weeks (retest + dossier + label). For a new OEM SKU: built into the standard 30-day lead time at no extra charge if your MOQ is ≥ 500 pcs.</p>
