FAQs
What sets your factory-trained technicians apart when installing tankless water heaters in Maryville?
Every installer on our team has completed the manufacturer’s factory-training program for the brands we carry (Rinnai, Navien, Noritz and Rheem). That means they understand the equipment inside and out, follow the latest installation bulletins and use only approved tools and parts. In addition, our plumbers hold current Tennessee state licenses, carry full insurance, and stay current on Maryville’s local building and gas codes, so your new system is installed safely, efficiently and fully code-compliant the first time.
How long will a tankless water heater installation take, and will I be without hot water all day?
Most residential replacements are completed in one visit lasting 4–6 hours. Your water is typically turned off for only 2–3 hours while we remove the old heater, connect the new gas or electric supply, and run the venting. We coordinate the schedule with you in advance, arrive with all needed parts on the truck, and test every fixture before we leave so you have hot water that same day.
Will I need to upgrade my gas line or electrical service for a new tankless unit?
Possibly, but not always. Gas models often require a ¾-inch gas line and a dedicated 120-volt outlet, while electric models may call for one or more 240-volt breakers. During your free in-home estimate our technician measures gas pressure, pipe size, vent path and panel capacity. If an upgrade is needed we give you a firm quote on the spot and handle all permits and inspections so there are no surprises down the road.
How do I know what size (GPM/BTU) tankless water heater my Maryville home needs?
Sizing is based on peak demand—the total gallons per minute (GPM) of hot water your household might use at the same time. Our technician counts fixtures, notes required temperature rise (groundwater in Maryville averages 55-60 °F), and then selects a unit with enough BTUs to reach your desired 120 °F set-point without dropping pressure. We give you a written sizing worksheet and explain future-proof options if your family grows.
What maintenance does a tankless water heater require, and can you take care of it?
Manufacturers recommend flushing the heat exchanger with a descaling solution once a year (every 6–12 months if you have hard water), cleaning the inlet filter, and checking venting and combustion settings. We offer a low-cost annual service plan that includes all of the above plus a full safety inspection. Regular maintenance keeps your warranty valid, maintains efficiency and extends the life of the unit.
What warranties and rebates are available for tankless water heater installations in Maryville?
Our primary brands include a 15-year heat-exchanger warranty, 5-year parts warranty and 1-year labor warranty—upgraded to 5-year labor when we perform annual maintenance. Fort Loudoun Electric Cooperative and TVA’s EnergyRight program often provide $150–$300 rebates for qualifying gas or electric tankless units, and we complete all paperwork for you. We’ll also file your building permit with the City of Maryville so you have documented proof of a code-approved installation.
