Overview
- co2online projects average €1,180 for gas‑heated households in 2025, up from €1,030 in 2024.
- The BVS reports ongoing cases of mould and moisture damage from underheating and warns against switching heating off.
- Guidance calls for roughly constant moderate temperatures — about 20°C in living rooms, 18°C in kitchens, 17°C in bedrooms, with around 16°C acceptable in bedrooms per consumer advice — and only small set‑backs when away.
- Prevention also requires brief shock or cross‑ventilation several times daily and keeping indoor humidity near 40–60%, with stricter targets in older, damp buildings.
- The GEV notes the frost‑protection setting holds rooms near 6°C and mainly protects radiators, while outside‑routed pipes remain vulnerable, and Ines flags low gas‑storage levels entering winter even as the government rejects supply‑gap concerns.
