Expert Takagi installation and service across San Francisco and Marin County. 70+ years of tankless-only engineering — commercial-grade copper heat exchangers built to last.
Hydroflow technicians are trained to install and service Takagi tankless water heaters. We understand the specific venting and gas line requirements for these units to ensure safe and efficient operation in San Francisco. We have extensive experience with Takagi installations particularly in neighborhoods like The Sunset and The Outer Richmond, where their exterior units thrive in coastal salt-air conditions. Takagi is one of our go-to brands for exterior coastal installations alongside A.O. Smith.
Takagi has focused exclusively on tankless water heating since 1952, making them one of the most specialized tankless manufacturers in the world. That singular focus shows in their product quality — commercial-grade copper alloy heat exchangers that outlast competitors' residential specs. For Bay Area coastal homes, Takagi's exterior-rated units are particularly valuable. We install flush valves on all exterior Takagi units as standard practice, making annual descaling and maintenance straightforward.
