The clearest signal in EPREL’s 2026 noise data is not a single “quietest” model, but a strong category and vendor concentration: the low-noise tail is dominated by air-water units, and WAMAK, s.r.o. owns 11 of the top 15 declared outdoor-sound-power slots. In a registry of 60,989 models from 777 manufacturers, that’s a useful reminder that the quietest listings are a narrow slice of the market, not a representative average.
Househeating Pulse’s EPREL snapshot puts the market-wide mean outdoor noise at 61.3 dB, with air-water units averaging 59.8 dB and air-air units 64.1 dB. Water-water machines are far quieter on paper at 42.0 dB, but the segment is tiny at just 31 models, so it should be treated as a niche outlier rather than a mainstream benchmark. The standout extreme is GESTION INTEGRAL DE ALMACENES, S.L. HTW-MKT2-V500, listed at 1 dB, while Panasonic Marketing Europe GmbH appears in the top 15 at 5 dB. Most of the top-ranked entries are clustered around the same manufacturer, which makes the leaderboard look more like a product-family pattern than a broad market ranking.
Efficiency does not appear to be the price of quietness. The average SCOP across the market is 4.55, yet several of the quietest WAMAK models land well above that, including TWW 48 EVI at 6.8 and TWW 110 WHR at 6.75. The same pattern shows up in type aggregates: water-water averages 6.15 SCOP, higher than air-water at 4.54.
The underlying tables matter here: the analysis is built from EPREL Public API snapshots, Househeating Pulse’s market-index and type-efficiency aggregations, and the refrigerant reference tied to the EU F-gas schedule.
