From radiant heating installs to high-efficiency boiler upgrades, Hydroflow is your trusted Inner Sunset plumbing 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: dedicated 110v or 220v electrical circuits, condensate drain lines with acid neutralizers, and sealed PVC venting routed to the exterior. 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.
The Inner Sunset sits where accessibility meets character. Most homes here have ground-floor garages or accessible basements that make plumbing upgrades far more straightforward than in mid-city flats. Proximity to our main supply houses on the west side means faster turnaround and better parts availability. With San Francisco's Title 24 deadlines approaching, now is the ideal time to plan ahead rather than scramble when the old tank fails.
The Inner Sunset is one of the best-positioned neighborhoods in SF for ADU radiant heating. Open garage frames and new concrete ADU pours create conditions that are hard to replicate later — and the Sunset's west-side supply houses mean we can get parts to your door faster than almost anywhere else in the city. If you're converting a garage, the best time to run radiant tubing is during the concrete pour or while the ceiling framing is exposed. A combi-boiler can handle both the ADU's radiant heating and domestic hot water from one compact wall-hung unit — no separate water heater needed.
