FAQs
What are the main benefits of switching to a tankless water heater in Cookeville?
A properly sized tankless unit delivers endless hot water on demand, so you never run out during back-to-back showers or laundry days. Because it heats water only when a tap is opened, a tankless model can reduce energy consumption by 25–40 % compared with a standard storage tank, cutting utility bills that are already rising in the Upper Cumberland region. The compact wall-hung design frees up floor space, the heat exchanger typically lasts 20+ years (almost double a tank’s life span), and Cookeville’s moderate winter climate keeps standby‐freeze risk low. Many models also qualify for federal tax credits and local TVA rebates.
How do I know what size tankless water heater my Cookeville home needs?
Sizing is based on two factors: 1) the maximum number of fixtures you expect to run at once, and 2) the temperature rise required. In Cookeville, incoming groundwater averages 55 °F. If you want 120 °F output, you need a 65 °F rise. Add the flow rates of simultaneous fixtures (e.g., 2.5 GPM shower + 1.5 GPM sink = 4 GPM). A family of four in a 2- to 3-bath home usually needs a gas unit rated around 7–9 GPM at 65 °F rise or a 27 kW electric model. Our technicians perform a free on-site load calculation, check gas line capacity, and recommend the right BTU/kW rating so you enjoy steady, comfortable hot water without overpaying for an oversized system.
What is the installation process and how long does it take?
1) We start with a home visit to verify venting options, gas or electrical requirements, and mounting location. 2) On installation day we drain and remove the old tank, reroute water lines, and, if gas-fired, upsize the gas line and install category-III stainless or concentric PVC venting through an exterior wall or roof. 3) The new unit is mounted, connections are leak-tested, and the controller is programmed. 4) Cookeville’s Building Codes Department generally requires a quick plumbing/mechanical inspection the same or next business day. Most residential jobs are completed in 4–8 hours; complex retrofits with long vent runs or significant gas upgrades may take a full day.
Are permits or code approvals required in Cookeville for a tankless water heater?
Yes. The City of Cookeville adopts the 2018 International Residential Code and the 2020 National Electric Code. A plumbing permit (and a mechanical permit for gas venting) must be pulled before work begins. Gas installations also require a pressure test and inspection. Our licensed, bonded plumbers handle all paperwork, schedule the inspection, and provide the homeowner with a Certificate of Completion, ensuring the installation is code-compliant and maintains your manufacturer warranty.
How much does a tankless system cost to install and what savings can I expect?
Installed pricing in the Cookeville market typically ranges from $3,200–$4,800 for a high-efficiency gas unit and $2,600–$3,600 for a whole-house electric model, including permits and haul-away of the old tank. Larger homes, long vent runs, or major gas line upgrades can add $500–$1,000. Because tankless units are 95 %+ efficient and eliminate standby losses, the average household saves $80–$150 per year on energy. Most customers see a 4- to 7-year payback, plus higher resale value thanks to the upgraded system.
What maintenance does a tankless water heater require and do you offer service plans?
Cookeville’s water hardness averages 8–12 grains, so manufacturers recommend a yearly flush with food-grade vinegar or citric solution to remove scale from the heat exchanger. The unit’s inlet screen and condensate trap (for gas condensing models) should also be cleaned annually, and the vent and combustion chamber inspected for debris. We offer an affordable Tankless Care Plan that includes the yearly descaling, full multi-point inspection, priority scheduling, and a 10 % discount on any out-of-warranty repairs. Regular maintenance not only extends the life of your unit but also keeps the warranty valid and efficiency at peak levels.
