Hard Water Protection for Tankless Units in Liberty, MO
Calcium scale is the most common cause of tankless heater failure. Water in much of Missouri is moderately hard to hard, so scale gradually builds in water heaters, faucets and fixtures. 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 added protection.

Tankless Water Heater Replacement in Liberty, MO
If your old tankless unit is failing or you are upgrading from a traditional tank, FGV Plumbing offers seamless tankless water heater replacement. We carefully remove the old unit, make any needed adjustments to plumbing and venting and install your new, more efficient model. Our goal is to make the transition as smooth as possible, keeping continuous hot water in your Liberty, MO home.
Recirculation Systems for Tankless Heaters in Liberty
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 fit your plumbing layout and usage patterns.
Tankless vs Tank Cost Comparison in Liberty, MO
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 Liberty
The cost of tankless water heater installation in Liberty usually ranges from $2,500 to $4,500, including the unit and labor. This can vary based on the model, fuel type (gas or electric) and any necessary upgrades to your gas lines or electrical panel. We provide a detailed, upfront quote after an on-site assessment.
Yes. Tankless water heaters are an excellent choice for Missouri 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, regardless of the climate.
We install Rinnai, Navien, Noritz and Rheem tankless water heaters. Each brand offers different features, efficiency levels and warranty terms.
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. FGV 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 detailed venting systems, all of which require specialized knowledge and adherence to safety codes. Incorrect installation can be dangerous and cancel warranties.
Size depends on how many fixtures run at once and your incoming water temperature. Most homes need a unit rated around 7 to 10 gallons per minute.
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. FGV Plumbing offers comprehensive maintenance services.
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 in particular, frequent error codes or a noticeable drop in hot water flow could point to a need for service or replacement.
