Is it worth using an SEAI grant to install a heat pump in your property? AdvertisementCurrently, the SEAI offers homeowners who install one a grant of €9,500 for an apartment or €12,500 for other properties. The SEAI only offers grants to homes with a Heat Loss Indicator which is equal to or less than 2.3 W/(K.m2). Ms Lynch added that once this is explained to homeowners, then the “willingness to adopt a heat pump falls way off”. Main image: A heat pump installed in the garden of a home in Ireland.
