This strategic partnership brings Ariston Group’s advanced global and regional expertise in water heating technology, R&D and manufacturing with the trusted brands, distribution channels, and the expansive customer network of Lennox. Together the two companies aim to strengthen their market presence and drive innovation across the North American residential water heater landscape.

“Ariston Group entered the North American market in 2016, building its presence through three acquisitions, recognizing this region as a strategic priority for profitable growth,” said Paolo Merloni, Executive Chairman of Ariston Group. “We are pleased to announce this new chapter with Lennox, an outstanding partner whose market leadership we respect deeply. This joint venture allows us to add to our existing commercial presence and brands an alliance with a strong partner. We are proud to be the technology provider behind high-efficiency solutions that will carry the Lennox brands.”

The joint venture will support the growth of Lennox and Ariston Group water heater sales across their respective channels and customers in the USA and Canada. Beginning in 2026, water heater products carrying the Lennox brands will be sold through Lennox stores, the direct-to-dealer network, and the distributor channel. Through its Ariston USA subsidiary, Ariston Group will continue selling to current customers under its brands.
