Frequently asked questions
Should I install a heat pump or do a full renovation first?
Start with insulation if your home is poorly insulated (DPE E, F, or G). A heat pump in an uninsulated home will be oversized and inefficient. The optimal sequence is: insulation first, then right-size the heat pump for the reduced heating demand.
Is a grouped renovation more cost-effective than separate works?
Yes, grouped renovations (insulation + heating replacement in one project) qualify for higher MaPrimeRenov subsidies and the grouped renovation bonus. They also avoid the inefficiency of installing a heat pump sized for an uninsulated home.
How much can a full renovation improve my DPE rating?
A comprehensive renovation (insulation + heat pump + ventilation) typically improves a property by 2-3 DPE classes. Moving from G to D or C is achievable and adds 6-14% to property value according to Notaires de France studies.
