Converting from a tank requires more than swapping units.

Venting changes from a metal flue to PVC or stainless, and the unit moves to a wall location. We remove and haul away your old tank and patch the old flue penetration.

Frequently Asked Questions About Tankless Water Heater Installation in South San Francisco
The cost for tankless water heater installation in South San Francisco can range from $3,000 to $6,000, depending on the unit type (gas or electric), brand, capacity and complexity of the installation, such as gas line upgrades or new venting. This price typically includes the unit and professional labor. We provide a detailed, no-obligation estimate after an on-site assessment.
Signs you might need a new water heater, tankless or otherwise, include a lack of hot water, rust-colored water, strange noises from the unit or frequent leaks. For tankless systems specifically, frequent error codes or a noticeable drop in hot water flow could point to a need for service or replacement.
Yes, tankless water heaters are very energy efficient in almost any climate. Coastal fog and moisture can speed corrosion on exposed fittings, so exterior valves and hose bibs deserve an occasional check. Since they only heat water on demand, they avoid the standby heat loss typical of traditional tanks, which can be substantial even in milder seasons.
Sizing a tankless water heater depends on your household's peak hot water demand, measured in gallons per minute (GPM), and the temperature rise needed. Our plumbers will count the hot water fixtures in your home and review your usage patterns to recommend the appropriate GPM and BTU rating for your needs in South San Francisco.
Yes, a permit is typically required because the job involves gas, venting and water connections. We pull the permit and schedule the inspection.
Most tankless water heaters come with a manufacturer's warranty of 10 to 15 years on the heat exchanger and 3 to 5 years on parts. FBL Plumbing also provides a warranty on our installation labor, which we will spell out in your service agreement.
In Northern California, plumbing and often gas or electrical permits are usually required for tankless water heater installation. FBL Plumbing handles all necessary permit applications and makes sure your installation passes all required inspections by local authorities.
To maintain efficiency and extend the lifespan of your tankless unit, annual flushing to remove mineral buildup is recommended, especially in areas with hard water. Checking and cleaning the air filter (for gas models) and inspecting connections are also part of regular maintenance. FBL Plumbing offers comprehensive maintenance services.
