High-efficiency upgrades and radiant heating for Inner Richmond's classic SF homes. Hydroflow handles the complexity.
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.
Upgrading a water heater to meet new high-efficiency standards can be difficult in older San Francisco Victorians, but homes in the Inner Richmond typically have layouts that make the transition much smoother and significantly less expensive. New high-efficiency units like Navien's NPE series require 110v power. In the Inner Richmond, electrical panels and gas meters are almost always within 15-20 feet of the water heater, saving you the cost of running new utility lines across the house.
