What installers will look at
- Heat loss: an SEAI technical assessment confirms the home is efficient enough for the grant.
- Radiators: older or smaller radiators often need upsizing for a heat pump's lower flow temperature.
- Outdoor unit position: away from the front of the house and far enough from neighbours to meet noise limits.
- Planning: most domestic heat pumps are exempt from planning permission if they meet the size, position and noise conditions.
- Electrics: the installer should check early whether ESB Networks needs to upgrade your supply.
