The strongest signal in the 2026 EPREL snapshot is not that one brand is “best,” but that output band explains more than brand reputation. In Househeating Pulse’s EPREL Public API snapshot, the market index covers 60,989 heat-pump models from 777 manufacturers, with 30,452 air-to-water units in scope. That matters because the full registry is dense enough to show how efficiency clusters by size, but it also exposes a hard limit: there is no purchase-price field in EPREL, so any true euro-for-euro ranking would require an external price table.
Within the visible air-to-water field set, brand concentration is high but efficiency leadership is fragmented. Daikin accounts for 14,668 listings, or 24.05% of the market, yet the top SCOP entries in the supplied leaderboard come from smaller names such as Risch, Master Therm, ProCalor, Walter Bösch, Kermi and Hoval. That mismatch is especially visible in the mid-range: Master Therm reaches 6.97 SCOP at both 10.0 kW and 13.0 kW, while Walter Bösch posts 6.90 at 8.0 kW and 6.78 at 10.0 kW, all in APPP. By contrast, some large-share brands do not appear in the visible top-50 SCOP cohort.
The small-output band shows the widest spread. At 1.0 kW, SCOP ranges from 3.15 to 4.77 in the sampled listings; at 2.0 kW it spans 2.75 to 4.97. That is why comparing within a narrow capacity slice is more defensible than comparing brand averages. The data also flags class mismatches: Mitsubishi Electric Hydronics 1.0 kW entries sit at SCOP 3.15–3.33 and class D, while the broader market is dominated by APPP listings.
For developers and data engineers, the reproducibility angle is straightforward: filter EPREL air-to-water records by power band, sort by SCOP, and validate against the market index snapshot and brand-share aggregation.
