Belgium installs record number of fixed air conditioners as heatwaves reset home comfort
Belgium has installed more fixed air-conditioning systems this year than in any year on record, according to Brussels broadcaster BX1, as repeated heatwaves push households and small businesses to treat cooling as infrastructure rather than luxury — a quiet…
In 30 seconds
- Belgium installed a record, all-time-high number of fixed air-conditioning systems this year, according to Brussels broadcaster BX1.
- Fixed climatiseurs are permanent split systems wired into a property, distinct from cheaper portable units used for short hot spells.
- The surge is attributed to repeated, intensifying heatwaves and housing stock built to retain heat rather than shed it.
- Wider cooling adoption raises summer peak electricity demand, a concern for grid operators and for emissions if power is not clean.
The story concerns a reported record in installations of fixed air-conditioning systems (split units permanently fitted to a property) in Belgium during 2026, driven by repeated heatwaves. Key named entities: BX1 (the Brussels broadcaster reporting the record); the Royal Meteorological Institute (IRM/KMI, which tracks heatwave frequency); grid operators Elia (transmission) and Fluvius/ORES (distribution); and consumer body Test Achats. It is primarily a Belgian climate-adaptation and consumer story with a broader European dimension, not an international-politics story.
Background
Air conditioning was historically rare in Belgian homes, associated with warmer southern European climates. Belgian building stock was designed for cold and damp, not sustained heat. Over recent years the Royal Meteorological Institute has recorded more frequent and intense heatwaves, gradually normalising discussion of mechanical cooling in a country that never traditionally needed it.
What to do
Households considering fixed cooling should size units correctly, weigh running costs and installation quality, and first exploit low-cost measures — shutters, insulation and night ventilation — to limit both bills and grid strain.
Impact
Regional — Dense urban areas, notably parts of Brussels with little greenery, feel the strongest pressure because the urban heat-island effect keeps nights warm, making cooling more attractive there. Flemish and Walloon housing built to retain heat faces the same retrofit question. Regional building codes and any cooling or heat-pump subsidy schemes will shape how the trend develops differently across Brussels, Flanders and Wallonia.
