Frequently Asked Questions About Tankless Water Heater Installation in Lebanon
The cost of tankless water heater installation in Lebanon 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 needed upgrades to your gas lines or electrical panel. We provide a detailed, upfront quote after an on-site assessment.
With annual descaling, tankless units often last 15 to 20 years. Skipping maintenance in hard water areas can shorten that significantly.
No, we strongly advise against DIY tankless water heater installation. These systems involve complex connections for gas, water and electricity, along with specific venting requirements. Improper installation can lead to safety hazards, void warranties and costly repairs. Always use a licensed professional.
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.
Many manufacturers offer 10 to 15 year heat exchanger warranties and shorter coverage on parts. We also guarantee our installation labor.
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. FVR Plumbing offers comprehensive maintenance services.
Tankless water heaters offer several key benefits: endless hot water on demand, significant energy savings from heating water only when needed, a longer lifespan (often 20+ years) and a compact, space-saving design. They also reduce the risk of tank leaks and the water damage that comes with them.
We install Rinnai, Navien, Noritz and Rheem tankless water heaters. Each brand offers different features, efficiency levels and warranties.
