FAQs
What are the main advantages of installing a tankless water heater in my Cowan home?
Tankless (on-demand) systems heat water only when you open a hot-water tap, eliminating standby heat loss typical of storage tanks. This can cut water-heating energy use by 25–40 %, provide an endless supply of hot water, free up floor space, and offer a life span of 20+ years—roughly double that of a conventional tank. In Cowan’s moderate climate, the improved efficiency translates into lower monthly utility bills and a reduced carbon footprint.
How long does a typical tankless water heater installation take?
A straightforward replacement of a tank unit with a gas tankless model takes about 4–6 hours. This includes removing the old tank, upgrading gas lines (tankless heaters generally need a ¾-inch gas supply), mounting the new unit, and venting it through the exterior wall or roof. Electric models may install slightly faster but can require panel upgrades. If major plumbing or electrical modifications are needed, the job can extend to a full day. We schedule a free pre-visit to give you an accurate timeline for your Cowan property.
Do I need a permit in Cowan or Franklin County to install a tankless water heater?
Yes. Both gas and electric tankless installations require a plumbing permit, and gas units need a mechanical permit as well. Our licensed team handles the permitting process with Cowan’s Building & Codes Department and coordinates any county inspections. All work is performed to the latest International Plumbing Code (IPC) and National Fuel Gas Code standards, ensuring safety and compliance.
What size (flow rate) tankless water heater should I choose?
Sizing is based on simultaneous hot-water demand. We add up the flow rates of fixtures you might run at the same time—a shower (2.0 gpm), a kitchen sink (1.5 gpm), and a washing machine (2.0 gpm) might require roughly 5.5 gpm. We also factor in Cowan’s average groundwater temperature (~58 °F) to calculate the temperature rise needed to reach 120 °F. Most households in the area are well served by units rated 7–9 gpm, but larger families or homes with luxury fixtures may need 11 gpm. During our in-home assessment we measure your actual demand and recommend the right model.
How much maintenance does a tankless system require?
Minimal but important. Because Cowan’s water is moderately hard, we recommend flushing the heat exchanger with a vinegar solution once a year to remove mineral buildup—this takes about one hour and prevents efficiency loss or damage. Gas models also need an annual combustion check for safety and peak performance. We offer affordable maintenance plans that include both services and extend your manufacturer warranty.
What is the cost of a tankless water heater install, and are there incentives?
Installed prices in Cowan range from $2,800–$4,500 for a whole-house gas unit and $2,200–$3,500 for electric, depending on capacity, venting complexity, and any needed electrical or gas upgrades. You may qualify for a 30 % federal tax credit (up to $600) under the Inflation Reduction Act, plus TVA’s EnergyRight rebates for high-efficiency water heaters when available. We provide written, upfront quotes and offer 0 % financing options to spread the cost over 12 to 24 months.
