KfW Program 459 is a KfW Bankengruppe grant product for companies replacing heating systems in residential buildings with climate-friendly equipment. The captured official KfW page identifies the product as Heizungsförderung für Unternehmen – Wohngebäude and states a subsidy of up to 35% of eligible costs. The page supports a direct company path through the applicant class Unternehmen and covers the purchase and installation of a new climate-friendly heating system. This is distinct from the non-residential company heating subsidy because the building class is Wohngebäude; it is also distinct from the private-person residential heating page because this product is explicitly for companies. The grant should be treated conservatively as a rolling KfW subsidy page with no fixed application deadline captured in the source facts.

Funds the purchase and installation of new climate-friendly heating systems in company-owned or company-managed residential buildings in Germany.
