Thermal kettles: a major summer comfort issue
Thermal boilers : These poorly insulated homes where the indoor temperature often exceeds 30 °C during heatwave peaks. In France, 35 % of the housing stock would be affected, a ratio even more pronounced in the mansard roofs of our Alpine resorts.
Tenant rights: rent payment and energy decency
- No rent suspension : even if the dwelling is uninhabitable, the tenant must continue to pay, unless a court decides otherwise.
- Possible remedies : formal notice, referral to the litigation judge to challenge decency.
- Decency 2025 : for now, overheating is not part of the legal criterion, but the DPE reform should incorporate "summer comfort" by 2030.
