Tankless vs Tank Cost Comparison in Concord, 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 offset 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 fits your budget.

Frequently Asked Questions About Tankless Water Heater Installation in Concord
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.
A standard tankless water heater installation, replacing an existing tank, usually takes 4 to 8 hours. If extensive plumbing or gas line changes are required, it may take a full day. Our team works efficiently to restore your hot water as soon as possible.
Yes. Tankless water heaters are an excellent choice for Northern California homes. Their energy efficiency can help manage utility costs, especially during peak demand. The compact size is great for the smaller utility closets common in many houses, and the endless hot water suits busy families throughout the year, whatever the climate.
Yes, gas tankless water heaters require specific venting materials and configurations different from traditional tank heaters. Many modern units use PVC or polypropylene for venting, and proper slope and termination are critical for safe and efficient operation. Electric units do not require venting.
Fluctuating water temperature, error codes, reduced flow and unusual noises are common signs. Scale buildup is often the cause in hard water areas.
Absolutely. When properly sized, a tankless water heater can provide an endless supply of hot water, even for large families. It is crucial to select a unit with a high enough GPM (gallons per minute) rating to meet your peak demand.
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 detail in your service agreement.
While it may seem appealing, tankless water heater installation is complex and should only be performed by a licensed professional. It involves gas lines, high-voltage electricity, water connections and intricate venting systems, all of which require specialized knowledge and adherence to safety codes. Incorrect installation can be dangerous and cancel warranties.
