FAQs
What are the main benefits of replacing my conventional tank water heater with a tankless model in Johnson City?
Tankless (on-demand) units heat water only when you open a tap, eliminating stand-by heat loss and trimming 20–40 % off typical water-heating bills. They provide endless hot water, free up floor space, last 18-25 years (about twice as long as a tank), and qualify for federal energy-efficiency tax credits. Our fully licensed plumbers size, install, and vent the units to local Johnson City mechanical and fuel-gas codes so you enjoy the efficiency without safety or performance worries.
How long does a professional tankless water heater installation usually take?
Most residential change-outs are completed in one working day. A straightforward gas-to-gas swap with existing ¾-inch gas line and accessible vent run takes 4–6 hours. If we need to upsize gas piping, add a condensate drain, or upgrade electrical service for an electric model, the job can extend to 6–9 hours. Before we begin, our licensed technician performs a site inspection and gives you a written timeline so you know exactly what to expect.
Will I have to upgrade my gas or electrical service to run a tankless water heater?
Maybe. Modern gas tankless units require ¾-inch gas piping and sufficient BTU capacity (150–199 k BTU). Older homes in Johnson City sometimes have ½-inch lines that must be upsized. Electric tankless heaters often need 120–150 amp dedicated breakers. During our free in-home estimate, we perform a load calculation, pressure test, and panel review. If upgrades are needed, we can handle all gas line re-piping or coordinate with a licensed electrician for panel work, and we quote the cost up front.
What size (flow rate) tankless water heater does my family need?
Sizing is based on simultaneous hot-water demand measured in gallons per minute (GPM) and the temperature rise needed in Northeast Tennessee’s climate. Add up the fixtures you might use at once—for example, shower (2.5 GPM) + kitchen sink (1.5 GPM) = 4 GPM. In winter, groundwater enters around 50 °F, so we design for a 70 °F rise to reach a comfortable 120 °F. A family of 3–4 typically chooses a 7–9 GPM gas condensing unit. During our consultation we run the numbers, discuss future needs, and recommend the right model so you never run out of hot water.
Are there rebates or incentives available for tankless water heater installations in Johnson City, TN?
Yes. Qualifying ENERGY STAR® gas tankless models installed by licensed professionals are eligible for a 30 % federal tax credit (up to $600). Tennessee Valley Authority (TVA) occasionally offers additional bill credits, and local gas utilities sometimes provide $100–$300 rebates for high-efficiency appliances. We keep track of current programs, supply the necessary model numbers and documentation, and even help you fill out the rebate forms so you don’t leave money on the table.
How often should a tankless water heater be serviced, and do you provide maintenance?
Manufacturers recommend annual service in areas with moderate to hard water—exactly what we have in Johnson City. A licensed plumber should flush the heat exchanger with food-grade descaling solution, clean the inlet filter, inspect the burner or heating elements, and run a combustion analysis. The visit takes about an hour and significantly extends the unit’s life. Our plumbing team offers affordable maintenance plans that include yearly flushes, priority scheduling, and warranty compliance paperwork.
