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 takeaway is methodological: the supplied EPREL slice cannot actually rank Serbia, Croatia, and Slovenia by brand share, refrigerant mix, or efficiency. The registry excerpt has no country-level model counts or brand tables for those three markets, so any national leaderboard would be a fabrication. That limitation is precisely why the live EPREL catalog view matters.
What the data does support is the broader structural backdrop. Across the European heat-pump base, Househeating Pulse tracks 60,989 listed models from 777 manufacturers, with average SCOP 4.55, average declared output of 9.3 kW, and average outdoor noise of 61.3 dB. The supplier field is already concentrated: Daikin Europe N.V. holds 14,668 models and 24.05% share, while Mitsubishi Electric Europe B.V. sits at 5,575 models and 9.14%. Add Johnson Controls Hitachi at 8.54%, and the top three already control 41.73% of all listings.
Refrigerants show a similarly narrow distribution. Declared entries are dominated by R32 with 13,935 listings—84.91% of the declared refrigerant set—while R290 remains small at 537 listings. Even after merging spelling variants like R290A/R290a, propane-coded entries only reach 540, or 3.29%. That makes any Balkan submarket with a materially different refrigerant profile easy to spot, but not quantifiable from this corpus alone.
Country context is only partial: Croatia is tagged with 2,957.86 heating degree days, electricity at €0.1658/kWh, and grid intensity of 134 gCO₂/kWh; Slovenia shows 3,314.5 heating degree days, electricity at €0.2121/kWh, and 207 gCO₂/kWh. Serbia is missing from the auxiliary country table.
For developers and data engineers, the real signal is reproducibility: the article is built from EPREL Public API aggregates, plus Eurostat, NASA POWER, and EEA-linked country context. Read the full analysis with live data at the canonical guide.
