Hestiia designs a connected electric radiator that generates cashback by reselling computing power via its Wi‑Fi connection. Its radiators are manufactured in France, were first installed in 2018, and are available for preorder across metropolitan France. The company claims the heaters deliver about 15% energy savings versus classic electric heating and can return several hundred euros per year in cashback (example: €250/year for a 50 m² apartment with two radiators). Hestiia provides a five‑year warranty, preventive maintenance every five years, and free replacement if needed, and emphasizes recyclability and reuse of materials. The startup was founded in 2013 and employs around fifteen people. To support scale-up and overseas rollout, Hestiia has secured fresh funding.
