Market evolution: Electric water heaters (CN 851610) — 2015–2025

Introduction

This report examines the evolution of EU trade in electric instantaneous and storage water heaters and immersion heaters (customs code 851610) over the 2015–2025 period. The data reveal a market that has undergone significant structural transformation: trade values have risen substantially while physical volumes have stagnated or declined, pointing to sharp unit-price inflation. At the same time, the geographic composition of both the EU's import suppliers and export destinations has shifted markedly, reflecting geopolitical disruptions and evolving competitive dynamics. Finally, EU domestic production has expanded dramatically, yet the bloc's net import reliance has also grown, suggesting that demand has outpaced even a rapidly scaling manufacturing base. The following three sections unpack these dynamics in detail.

1. A Market of Rising Values and Falling Volumes

The most striking feature of the EU electric water heater market over the decade is the divergence between trade values and physical quantities. While the euro value of both imports and exports grew significantly, the number of units traded declined, indicating a pronounced shift toward higher-value products and/or substantial price inflation.

EU imports grew in value but not in unit count

Over the 2015–2025 period, EU imports rose from €378 million to €590 million (+56.1%), yet the supplementary quantity — the number of individual items imported — fell from 33.4 million to 28.7 million (−14.1%). The per-item import price more than compensated, climbing from €11.3 to €20.6 (+81.7%).

The near-constant mass (+4.6%) alongside a falling item count implies that the average imported unit became heavier — consistent with a product mix tilting toward larger-capacity storage water heaters rather than lighter immersion elements.

EU exports show an even sharper unit-value transformation

On the export side, the EU shipped €285 million worth of product in 2015 and €395 million in 2025 (+38.6%), yet export tonnage fell from 45,059 t to 38,440 t (−14.7%) and the unit count dropped from 7.4 million to 5.5 million items (−25.4%). The per-item export price nearly doubled, from €38.5 to €71.5 (+85.8%).

The export price per item (€71.5 in 2025) is far higher than the import price (€20.6), indicating that the EU specialises in higher-end, premium-priced water heaters for export while importing predominantly lower-cost units.

Instantaneous heaters are the high-value segment

The product segment breakdown reveals a stark price differential between instantaneous water heaters (CN 85161011) and storage/immersion heaters (CN 85161080):

EU exports of instantaneous heaters are priced at nearly five times the import price of the same category, confirming the EU's positioning in the premium, technology-intensive segment. Meanwhile, the import side is dominated by mass-market storage heaters: CN 85161080 accounted for 23.4 million of the 28.7 million items imported in 2025, but only €423 million of the €590 million total value.

2. Geographic Realignment: Shifting Suppliers and Destinations

The decade saw a major reconfiguration of the EU's trading partners in this product category, driven by geopolitical events, emerging manufacturing hubs, and evolving demand patterns. China consolidated its dominance on the import side, Egypt emerged as a major secondary supplier, and Russia virtually disappeared from both imports and exports.

China remains the EU's largest import source but with a volatile trajectory

China supplied €227 million of electric water heaters to the EU in 2015 and €305 million in 2025 (+34.3%). However, this linear comparison obscures considerable volatility: Chinese imports peaked at €437 million in 2022 before retreating sharply. A price shock in 2022 — with an abnormality score of 11.9 and a price shift of +133.7% — coincided with post-pandemic supply chain disruptions and energy cost pass-through. China's import value coefficient of variation (0.21) confirms moderate year-to-year instability.

Egypt and the United Kingdom surged as import sources

The most dramatic growth among EU import partners came from Egypt, which saw imports rise from €36 million to €85 million (+135.9%), and the United Kingdom, where imports grew from €24 million to €40 million (+70.9%). Egypt's emergence reflects the growth of manufacturing capacity in North Africa, potentially linked to cost-competitive production and proximity to southern European markets. The UK's rise is at least partly a post-Brexit statistical reclassification effect, with flows that were previously intra-EU now counted as extra-EU trade.

Russia's collapse reflects geopolitical sanctions

Russian Federation imports fell from €4.8 million in 2015 to essentially zero (€52) in 2025 (−100%), while EU exports to Russia dropped from €21.5 million to €6.0 million (−72.1%). Both trajectories reflect the impact of EU sanctions imposed following the 2022 invasion of Ukraine. The Russian import coefficient of variation (0.77) — the highest among all partners — captures this abrupt collapse. Notably, Ukraine simultaneously became a fast-growing EU export destination (from €8 million to €15 million, +84.3%), likely reflecting wartime reconstruction and humanitarian demand for water heating equipment.

EU exports diversified toward North Africa and the Middle East

On the export side, the most notable growth came from Morocco (+160.7%, from €7.5 million to €19.4 million) and the United Arab Emirates (+62.5%, from €17.2 million to €28.0 million). The United Kingdom remained the EU's single largest export market at €38.1 million, though it experienced modest decline (−4.9%) and considerable volatility (CV of 0.42).

Import concentration declined, signalling supply diversification

The Herfindahl-Hirschman Index (HHI) for imports by value fell from 3,806 to 3,020 (−20.7%), moving from a moderately concentrated structure toward greater diversification. Export concentration was already low (HHI of 624 in 2015) and remained so (589 in 2025), consistent with a broad spread of EU export destinations.

3. EU Production Boom alongside Growing Trade Openness

The 2015–2025 decade witnessed a remarkable expansion of EU domestic production of electric water heaters, yet the bloc simultaneously became more reliant on imports and more engaged in international trade overall. This paradox is explained by demand growth outpacing even a rapidly expanding production base.

EU production volumes tripled

According to PRODCOM data, EU production of electric water heaters grew from 3.6 million items in 2015 to 11.1 million items in 2025 (+209.8%). Production value rose even faster, from €399 million to an estimated €2.0 billion (+401.6%). This enormous increase in the unit value of production — from roughly €111 per item to €180 per item — mirrors the trade-side price inflation and points to a product mix upgrading toward higher-capacity, higher-margin appliances.

Germany and Italy dominate EU production and exports

Within the EU, Germany emerged as the bloc's export powerhouse, more than doubling its extra-EU exports from €70 million to €157 million (+124.0%). Italy remained the second-largest exporter at €115 million and showed the highest revealed comparative advantage (RCA) among large member states (2.16). Bulgaria recorded the most spectacular export growth (+212.1%, from €8.3 million to €25.9 million) and also the highest RCA in the EU (8.92), confirming its emergence as a specialised production hub.

Several member states shifted from production to import reliance

In contrast, Czechia's exports collapsed from €20.1 million to €5.4 million (−73.1%), suggesting a loss of competitive capacity. Meanwhile, several western European countries dramatically increased their imports: Spain (+208%), France (+282%), and Belgium (+134%) all saw imports surge, likely driven by electrification of heating, building renovation cycles, and growing demand for heat-pump-compatible water heaters.

Net import reliance and trade openness both increased sharply

The EU's net import reliance on third-country suppliers rose from 3.7% to 8.5% (+131.3%) over the period, peaking at 13.0% in 2022. Simultaneously, trade intensity (imports + exports as a share of production) surged from 9.8% to 41.4% (+324.9%), and export propensity (exports as a share of production) jumped from 3.3% to 22.7% (+585.3%).

This pattern indicates that the EU's electric water heater industry has become far more internationally oriented: it produces more, exports more, but also requires more imports to satisfy domestic demand. The growing export propensity aligns with the EU's strategic push to electrify heating under its climate policy framework, which has stimulated both domestic production investment and cross-border trade.

Conclusion

Over the 2015–2025 decade, the EU market for electric water heaters (CN 851610) has been reshaped by three intersecting forces: significant price inflation that raised trade values even as unit volumes declined; a fundamental geographic realignment of trading partners driven by geopolitical disruption and the rise of new manufacturing centres; and a dramatic expansion of EU production that has nonetheless failed to keep pace with surging demand. The result is a market that is simultaneously more productive, more trade-intensive, and more reliant on third-country supply than it was a decade ago. For policymakers, the key takeaway is that while the EU has strengthened its position as a high-value exporter — particularly in instantaneous water heaters — it remains structurally dependent on imports of mass-market storage heaters, predominantly from China and increasingly from Egypt. The collapse of Russia-related trade flows has been absorbed without major disruption, but the combination of rising import reliance and persistent price inflation warrants continued attention to supply chain resilience and production competitiveness.
