From tankless units in tight Victorian utility closets to heat pump water heaters in Sunset garages, we install the right water heater for your SF home. Every installation includes water pressure testing to protect your new unit from SF's demanding water system.
SF's water pressure frequently exceeds 130 PSI — far above the 80 PSI maximum safe limit. Installing a new water heater without testing and managing this pressure means your new unit will fail years ahead of schedule. We test on every single installation and install a PRV if needed.
Safe pressure: 65 PSI · What we often see in SF: 130–140 PSI
Victorian flats, Edwardian row houses, and compact Sunset bungalows often have utility closets designed for nothing more than a small tank heater. We specialize in wall-mounted tankless units and compact heat pump models that deliver more hot water while taking up less space.
Compact installations designed for SF
The San Francisco Department of Building Inspection requires permits for all water heater replacements, including seismic strapping, expansion tanks, and proper venting. We manage the entire process — from filing to final inspection.
We manage the entire SF DBI process
Before touching your existing unit, we test your water pressure. If it's above 80 PSI, we install a pressure-reducing valve as part of your installation. This protects everything downstream — not just the water heater.
We calculate your home's actual hot water demand — number of occupants, peak usage times, and recovery rate requirements — to spec the correct unit. Most SF homes are undersized and frustratingly run out of hot water.
We handle all DBI permits, seismic strapping, expansion tanks, and proper venting. Everything done to SF code, protecting your home and its resale value.
We protect your home, remove your old unit for responsible disposal, walk you through the new system's controls, and leave cleaner than we arrived.
For Sunset and Richmond homes with garages, heat pump units from Rheem ProTerra and A.O. Smith are 3-4x more efficient than standard electric tanks and qualify for significant rebates.
For homes with radiant floor heating, a combi-boiler handles both space heating and domestic hot water in one unit, eliminating the need for a separate water heater entirely.
Same-day installation available for most SF neighborhoods. We'll test your water pressure, spec the right unit, and handle all the permits.
