2026 heat-pump market index: Austria vs Hungary vs Slovakia

A data-led comparison of three neighbouring Central European markets using EPREL listings, brand shares, refrigerant mix, efficiency and price. The piece will show where buyers get the strongest choice and which market looks most mature in 2026.

Austria has the stronger claim to being the most mature heat-pump market of this three-country set, but the evidence in the corpus is narrower than the headline might suggest. The key limitation is simple: the research block includes country-level energy and climate data for Austria, Hungary and Slovakia, but it does not include country-level EPREL listing counts, brand counts, SCOP averages, refrigerant shares, inverter shares, price bands, brand concentration or type mix for those three markets specifically. Where the registry or the supplied dataset does not record a country split, that cannot be inferred.

What can be said, with numbers, is that all three markets sit in the same “average” climate zone, which makes them a reasonable regional comparison set: Austria is tagged as average climate with 3,309.19 annual heating degree days, Hungary with 3,060.58, and Slovakia with 3,035.92 (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). That is a spread of 273.27 heating degree days from Austria to Slovakia (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register), small enough that product availability and commercial positioning matter at least as much as climate.

For readers wanting the broader European baseline behind this comparison, the live market index, the 32-country country comparison dashboard and the full EPREL catalog are the relevant navigation points.

Market size and choice: how many models and brands each country gets

The article’s first question cannot be answered directly from the supplied corpus. The dataset does not provide EPREL-listed heat-pump model counts or distinct brand counts for Austria, Hungary or Slovakia separately. It only gives the pan-European snapshot: 60,989 total models and 777 total manufacturers in the indexed universe as of 2026-06-30 (market_index_snapshot / Househeating Pulse · Market Index v1, computed from EPREL Public API).

That means no defensible ranking can be published here for “Austria vs Hungary vs Slovakia” on raw choice breadth. The registry basis is large at European level, and readers can inspect the live manufacturers index or the filtered heat-pump catalog, but this corpus does not include national listing counts.

What is visible is that Austria, Hungary and Slovakia are operating in broadly similar climatic conditions while facing very different household energy price signals. Electricity prices are highest in Austria at €0.3272/kWh, versus €0.1853/kWh in Slovakia and €0.1082/kWh in Hungary (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). Gas prices show the same ordering: Austria at €0.1221/kWh, Slovakia at €0.0608/kWh and Hungary at €0.0335/kWh (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register).

That matters because a mature market is usually visible in observable product depth and product mix. This corpus does not expose those national catalog counts, so the stronger claim is limited to economics and incentives rather than measured country-level assortment. Austria also has a recorded maximum subsidy of €23,000, Slovakia €3,400, while Hungary has no active subsidy and no maximum subsidy recorded in the supplied register (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). Buyers comparing support can cross-check the live subsidy index and the Austria and Slovakia pages under country subsidies and Slovakia subsidies.

Efficiency comparison: SCOP, capacity and noise across the three markets

The second question also runs into a data boundary. The corpus does not provide average SCOP by country for Austria, Hungary and Slovakia, so the gap between the strongest and weakest of those three national markets cannot be quantified from this research block.

The European benchmark across all indexed models is an average SCOP of 4.55, average power of 9.3 kW and average outdoor noise of 61.3 dB (market_index_snapshot / Househeating Pulse · Market Index v1, computed from EPREL Public API). That gives a reference point, not a country ranking.

By type, the strongest average efficiency in the corpus belongs to water-water units at SCOP 6.15, followed by ground-water at 4.77 and air-water at 4.54 (type_efficiency / EPREL Public API · type aggregation). Average capacity differs sharply by type: water-water averages 35.65 kW, ground-water 18.45 kW, air-water 11.83 kW and air-air 5.41 kW (type_efficiency / EPREL Public API · type aggregation). Outdoor noise also varies, with water-water at 42.0 dB, ground-water at 58.8 dB, air-water at 59.8 dB and air-air at 64.1 dB (type_efficiency / EPREL Public API · type aggregation).

Those distinctions matter more than marketing labels. A buyer focused on efficiency can use the top SCOP leaderboard or the narrower air-to-water SCOP leaderboard. The highest SCOP model in the corpus is Risch Kälte- und Klimatechnik GmbH OH I 4esr TWW W/W at 7.0, while leading water-water entries such as Waterkotte GmbH EcoTouch DS 5034.5 T (water/water) and Waterkotte GmbH CTC EcoTouch 525 (water/water) reach 6.97 (top_models / EPREL Public API via Househeating Pulse catalog).

The climate similarity between the three countries keeps this comparison useful. Austria’s 3,309.19 annual heating degree days are above Hungary’s 3,060.58 and Slovakia’s 3,035.92 (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register), but the difference is modest relative to the much bigger efficiency spread between product types themselves.

Refrigerants and technology mix: R290, inverter share and type diversity

Three of the article’s required questions cannot be answered at country level from this corpus: national R290 shares, national inverter shares and national type diversity for Austria, Hungary and Slovakia are not recorded here.

At European level, the indexed market remains heavily concentrated in fluorinated refrigerants. The market index reports a natural refrigerant share of 3.27% (market_index_snapshot / Househeating Pulse · Market Index v1, computed from EPREL Public API). In declared refrigerant usage, R290 appears in 537 listings, while R32 appears in 13,935 and R410A in 1,896, with smaller variant spellings also present in EPREL declarations (market_index_snapshot / Househeating Pulse · Market Index v1, computed from EPREL Public API). The refrigerant reference table classifies R290 as propane with GWP 0 and natural status true, while R32 carries GWP 771 and R410A GWP 1924 (refrigerant_universe / IPCC AR6 GWP table; EU Reg. 2024/573 phase-out schedule; EPREL declared codes).

That makes the strategic direction clear even if the Austria-Hungary-Slovakia split is missing: low-GWP adoption is still a minority position in the indexed universe. Readers can inspect the R290 catalog filter, compare it with the R134a filter, or use the refrigerants reference alongside the EU’s F-gas regulation framework.

The registry also does not record inverter share in the supplied country-level comparison block, so any claim that Austria materially leads Hungary and Slovakia on inverter penetration would be unsupported here. The same caution applies to type diversity by country. Europe-wide, air-water dominates with 30,452 listings, followed by air-air at 21,065 and heat-pump water heaters at 9,228; ground-water and water-water are much smaller at 213 and 31 respectively (market_index_snapshot / Househeating Pulse · Market Index v1, computed from EPREL Public API). Buyers looking for the most efficient hydronic segment should start in the air-water catalog and ground-source catalog.

Price and entry-level availability: where buyers find the cheapest models

This is the clearest gap in the research corpus. The supplied data does not include country-level model prices, low-price shares or affordable-end concentration for Austria, Hungary or Slovakia. It therefore cannot support a ranking on “where buyers find the cheapest models”.

The only price information in the corpus is not product pricing but household energy pricing. On that basis, Hungary has the lowest recorded electricity price at €0.1082/kWh, followed by Slovakia at €0.1853/kWh and Austria at €0.3272/kWh (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). Gas follows the same order: Hungary €0.0335/kWh, Slovakia €0.0608/kWh, Austria €0.1221/kWh (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register).

That means operating-cost arithmetic differs materially across the three countries even if model-level upfront price data is absent. Austria’s higher electricity tariff raises the value of higher seasonal efficiency, while its far larger recorded subsidy ceiling of €23,000 may offset upfront costs more aggressively than Slovakia’s €3,400 and Hungary’s zero active schemes in the register (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). Readers can test those interactions in the payback calculator and subsidy calculator.

Brand concentration: which market is most crowded and which is most dependent on a few makers

Again, the national ranking cannot be completed from this corpus because brand concentration by country is not supplied for Austria, Hungary or Slovakia. The dataset only includes a Europe-wide brand-share table.

At that European level, Daikin Europe N.V. leads with 14,668 models and a 24.05% share, ahead of Mitsubishi Electric Europe B.V. on 5,575 models and 9.14%, and JOHNSON CONTROLS HITACHI AIR CONDITIONING EUROPE SAS, SUCURSAL EN ESPAÑA on 5,207 models and 8.54% (brand_share / EPREL Public API · brand-share aggregation). Bosch Thermotechnik GmbH follows at 3,602 models and 5.91%, with Ariston SpA at 2,618 and 4.29% (brand_share / EPREL Public API · brand-share aggregation).

Those numbers show a catalog that is broad in absolute terms but top-heavy in model count. They do not show whether Austria is less concentrated than Hungary or Slovakia. The registry basis needed for that answer is absent from the prompt. Readers comparing manufacturer breadth can use the leaderboards hub, individual brand profiles such as Vaillant GmbH and BDR Thermea Group B.V., or the complete manufacturer directory.

What the comparison means for buyers, installers and market watchers

The most defensible reading from this corpus is not that Austria is proven to have a larger or less concentrated EPREL assortment than Hungary or Slovakia. The corpus does not provide those country-level catalog splits.

What it does show is that the three countries are climatically comparable, while Austria stands apart on cost structure and subsidies. Austria has the highest electricity price of the group at €0.3272/kWh and the highest gas price at €0.1221/kWh, compared with Hungary’s €0.1082 and €0.0335, and Slovakia’s €0.1853 and €0.0608 (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register). Austria also has by far the largest recorded maximum subsidy at €23,000, versus €3,400 in Slovakia and no active scheme recorded for Hungary (country_compare / Eurostat · NASA POWER · EEA · Househeating Pulse subsidy register).

For buyers, that means Austrian purchasing decisions are likely more sensitive to SCOP and subsidy capture than those in Hungary, where lower retail energy prices weaken the payback case on operating economics alone. For installers, the common climate zone suggests similar design logic across the region, best checked with the sizing calculator and the climate-fit tool. For journalists and market watchers, the main takeaway is methodological: if the question is about country-level choice, concentration, refrigerants or low-price availability, the published answer is only as strong as the country-level EPREL cut behind it. This prompt does not contain that cut.

For readers wanting the underlying registry mechanics, the official EPREL portal and Househeating Pulse methodology notes are the right references.
