Hard Water Protection for Tankless Units in San Marcos, CA
Calcium scale is the most common cause of tankless heater failure. Municipal water across much of Southern California is hard, leaving white scale on faucets, showerheads, and inside water heater tanks. Scale coats the heat exchanger, reducing efficiency and triggering error codes. We install isolation valves so the unit can be flushed with a vinegar or descaling solution once a year. A scale inhibitor cartridge or whole-home softener provides extra protection.
Commercial Tankless Water Heater Services in San Marcos, CA
Businesses in San Marcos benefit from the continuous hot water supply and compact design of commercial tankless water heaters. From restaurants to hair salons, we install robust systems designed to meet high-demand commercial needs. FKM Plumbing understands the requirements for commercial installations, including larger capacity units and commercial plumbing codes, so your business never runs out of hot water.
Tank to Tankless Conversions in San Marcos
Converting from a tank requires more than swapping units. A 40 gallon tank heater uses roughly 40,000 BTU, while a whole-home tankless unit may need up to 199,000 BTU, so the gas line often needs to be upsized. 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.
Tankless vs Tank Cost Comparison in San Marcos, CA
Tankless installation costs more upfront than a standard tank because of the unit price, gas line upgrades and venting changes. Over time, lower standby energy losses and a longer expected lifespan make up for part of that cost. Tankless units often last 15 to 20 years with proper descaling, compared with about 8 to 12 years for many tanks in hard water areas. We give you a side-by-side quote so you can decide what suits your budget.
Tankless Water Heater Relocation in San Marcos
Sometimes the ideal spot for a tankless water heater is not where your old tank was located. For homeowners in San Marcos looking to free up space or improve access, FKM Plumbing offers professional tankless water heater relocation. This can involve rerouting gas or water lines and possibly electrical work, all handled with precision and to local codes by our experienced team.
Recirculation Systems for Tankless Heaters in San Marcos
Tankless heaters can take a few extra seconds to deliver hot water to distant fixtures. A recirculation pump or dedicated return line keeps hot water close to faucets, reducing wait time and water waste. Some units have built-in pumps with smart scheduling. We design the system to suit your plumbing layout and usage patterns.

Frequently Asked Questions About Tankless Water Heater Installation in San Marcos
Most gas tankless installations cost $3,000 to $6,500 including the unit, labor, venting and common gas line upgrades. Electric units can be less, though panel upgrades can add $1,000 to $3,000.
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 routine maintenance. FKM Plumbing offers comprehensive maintenance services.
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. FKM Plumbing also provides a warranty on our installation labor, which we will spell out in your service agreement.
With annual descaling, tankless units often last 15 to 20 years. Skipping maintenance in hard water areas can shorten that significantly.
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 San Marcos.
We install Rinnai, Navien, Noritz and Rheem tankless water heaters. Each brand offers different features, efficiency levels and warranties.
Yes, installing a new tankless water heater or replacing an existing one in San Marcos typically requires a plumbing permit. This ensures the installation meets local building and safety codes. FKM Plumbing handles all required permitting paperwork for you.
Fluctuating water temperature, error codes, reduced flow and unusual noises are typical signs. Scale buildup is often the cause in hard water areas.
