Short read. This is a ~300-word brief based on the full analysis at Househeating Pulse. For the interactive charts, brand-level data, and source tables, open the original.
The sharpest signal in this EPREL-based index is not a country ranking; it is the split between mainstream catalogues and specialist ones. Across the 2026-05-31 snapshot, Househeating Pulse’s Market Index v1 covers 60,989 listed models from 777 manufacturers, with an overall average SCOP of 4.55. But that average hides a lot of structure: water-to-water models average 6.15 SCOP, while ground-water sits at 4.77 and air-water at 4.54. In other words, the “better” markets are likely the ones with more hydronic and ground-coupled inventory, not just the ones with more products.
That matters for the smaller EU-15 markets in this guide, because the registry is a catalogue, not a sales ledger. EPREL tells you what manufacturers registered, not what households bought, so this analysis focuses on product mix, refrigerant choice, declared efficiency and brand concentration rather than installed base.

Three numbers frame the market structure. First, A+++ already accounts for 23,466 models, or about 38.5% of the full catalogue, with A++ adding another 8,924. Second, Daikin Europe N.V. remains the dominant manufacturer at 14,668 models and 24.05% share, far ahead of Mitsubishi Electric Europe B.V. at 9.14%. Third, refrigerant transition is real but incomplete: R32 appears on 13,935 listings, R410A on 1,896, while R290 is still only 537 listings, or 3.27% of the catalogue on the normalized market-index measure.
For developers and data engineers, the interesting part is reproducibility: the article cross-checks EPREL Public API aggregates against type, brand-share and refrigerant tables, with climate and policy context from Eurostat, NASA POWER and the EEA. The full post expands the smaller-market framing and shows why the real divide is fragmented high-efficiency catalogues versus concentrated mainstream ones.
