San Francisco's high water pressure, tight Victorian layouts, and strict DBI codes make boiler work uniquely challenging. We are SF's boiler specialists — from high-efficiency combi installations to annual maintenance on vintage radiant systems.
SF's water pressure frequently exceeds 130 PSI — nearly double the 80 PSI maximum safe limit. Every boiler we install or service in SF starts with a water pressure test. Installing new equipment without managing this pressure means premature failure in 3-5 years instead of 15-20.
Safe: 65 PSI · Maximum safe: 80 PSI · Typical SF: 130–140 PSI
SF's housing stock presents unique spatial and structural challenges. Victorian flats have mechanical rooms sized for a 1960s water heater. Multi-unit Edwardian buildings have boiler rooms with 6-foot ceilings and no rear access. We specialize in making the right equipment fit the right space.
