Ariston, a global leader in high efficiency thermal comfort and water heating solutions, has announced a strategic partnership with Keyline Sales, appointing the premier manufacturers’ representative agency to manage sales, distribution, and specification efforts across Southern California and Wayne County, Nevada.

The partnership comes at a period of rapid market growth for sustainable water heating technologies. Driven by California’s strict building decarbonization goals, strict Title 24 energy mandates, and shifting consumer demand, the region has become a key focal point for electrification. Through this new partnership, Ariston aims to accelerate its regional footprint by delivering high efficiency heat pump water heaters, advanced thermal comfort technology, and tailored services to local wholesale distributors, mechanical contractors, engineering specifiers, and residential builders.

Keyline Sales brings decades of established market presence, robust warehousing, and deep builder-focused sales expertise to the partnership. With a dedicated builder and engineering team, Keyline is positioned to help homebuilders, multi-family developers, and plumbing professionals meet strict energy codes without sacrificing installation speed or product reliability.

"Southern California represents one of the most dynamic and fastest growing markets for clean energy water heating solutions in North America," said Mike Sokaris, vice president of sales at Ariston. "Keyline Sales shares our commitment to innovation, sustainability, and exceptional customer support. Their established relationships with top regional builders, contractors, and distributors make them the ideal partner to drive our expansion. Together, we look forward to making Ariston's water heating solutions and advanced heat pump technologies the top choice for new residential and commercial developments and repair and replace applications."

Ariston’s heat pump technology offers homebuilders a future-proof path toward zero emission and energy efficient building compliance. Keyline Sales will represent Ariston’s full line of standard and high efficiency water heating products across Southern California. Keyline Sales operates out of their corporate facility in Downey, Calif.

"We are thrilled to represent Ariston in Southern California," said Keith Katz, president at Keyline Sales. "As the market accelerates toward heat pumps and electrification, builders and contractors need reliable, high performing products backed by strong technical support. Ariston's innovative product lineup aligns perfectly with what our builders and channel partners are demanding. We look forward to driving mutual growth for years to come."
