From emergency repairs and radiant heating to high-efficiency boiler and water heater upgrades, Hydroflow is your local Outer Sunset specialist.
Starting soon, non-compliant standard gas water heaters will be phased out of California. When your old tank fails, you will likely be forced to upgrade to a high-efficiency condensing unit or a heat pump.
Upgrading isn't as simple as swapping a tank. High-efficiency units require entirely new infrastructure:
Our Advice: If you are planning a remodel right now, run the utilities early! Even if you aren't replacing the heater yet, getting the drain, vent route, and electrical in place will save you thousands of dollars down the road.
Upgrading to high-efficiency can be complex elsewhere in the city, but homes in the Outer Sunset typically boast ~1,500 sq ft layouts with distinct architectural advantages that make the transition much easier and more cost-effective. Being close to the ocean also requires specially resilient hardware.
Most water heaters here are located downstairs in the garage or basement. This offers perfect access for our installation crews and heavily reduces the need for intrusive drywall removal in your living spaces.
Because electrical panels and gas meters are frequently located within 15-20 feet of the water heater in Outer Sunset garages, you save thousands. We don't have to pull 110v lines across the house to power highly-efficient Navien combi-boilers.
High-efficiency units create acidic condensate. The proximity to ground-level laundry or utility sinks typically found in Outer Sunset homes makes safely neutralizing and routing this drain line simple, protecting your cast-iron pipes.
Many Outer Sunset properties have easy access to an exterior wall for safe PVC venting. If you decide to mount an outdoor unit to save interior space, we specialize in rugged, weather-rated A.O. Smith units built specifically to handle the coastal salt air without corroding.
Bonus: With our favorite supply houses located near the Sunset and easier street parking than downtown, our vans can get loaded properly and to your door faster—meaning we can typically finish the job quicker.
