FAQs
How does a tankless water heater save energy compared to a traditional storage tank model?
Tankless units heat water on demand, meaning they only consume gas or electricity when a hot-water tap is open. Traditional tanks keep 40–80 gallons of water hot 24/7, cycling the burner or heating elements repeatedly. In Friendsville’s mild-to-cool climate, tankless models typically cut standby heat loss entirely and can reduce water-heating energy use by 25–40 %—even more if you install low-flow fixtures or a recirculation loop with a timer.
What size (flow rate) tankless water heater do I need for my Friendsville home?
Sizing is based on simultaneous demand and incoming groundwater temperature. In Friendsville, winter inlet water averages about 50 °F, so raising it to 120 °F requires a 70 °F rise. Add the maximum gallons per minute (GPM) you expect to run at once—e.g., one shower (2.0 GPM) + kitchen sink (1.0 GPM) = 3 GPM. A unit rated for at least 3 GPM at a 70 °F rise would work. Larger homes with multiple bathrooms might need 7–9 GPM or two smaller units in parallel. Our technicians perform a full load calculation during the estimate to ensure proper sizing.
Can a tankless water heater be installed in the same place as my old tank?
Often yes, but there are factors to verify. Tankless units are smaller and wall-mounted, freeing floor space, yet they require: (1) proper gas line capacity (usually ¾″), (2) 120 V outlet for electronics, (3) category III/IV stainless or PVC venting, and (4) condensate drain for high-efficiency models. If your old tank’s location lacks any of these, we can relocate the unit to an exterior wall or upgrade utilities. Our Friendsville team will inspect current infrastructure and quote any needed modifications upfront.
What local permits or codes apply to tankless water heater installation in Friendsville?
Blount County and the City of Friendsville follow the 2018 International Plumbing Code and fuel-gas provisions. A plumbing/mechanical permit is required for any water heater replacement. Gas line upsizing, vent terminations, and condensate disposal must meet code; pressure testing may be requested by the inspector. Our licensed plumbers pull all permits, schedule inspections, and provide a certificate of completion for your records, so you stay fully compliant without hassle.
How much maintenance does a tankless water heater need?
Minimal but essential. In Friendsville’s moderately hard water (around 5–6 gpg), we recommend an annual flush with white vinegar or descaling solution to remove mineral buildup on the heat exchanger. This task takes about 45 minutes and preserves efficiency as well as warranty coverage. The unit’s inlet water screen should also be cleaned annually. We offer a low-cost maintenance plan that includes descaling, vent check, and diagnostic scan.
What is the typical cost and payback period for a tankless installation in Friendsville?
Installed pricing ranges from $2,900 to $4,800, depending on capacity, gas line upgrades, and venting route. Annual energy savings vs. a standard 50-gallon gas tank average $90–$140 in our area. Additional benefits include virtually unlimited hot water and an appliance lifespan of 20+ years (vs. 10–12 for tanks). When factoring energy savings, avoided tank replacements, and potential TVA or manufacturer rebates, most homeowners break even in 6–8 years—sooner if they have high hot-water usage or choose ENERGY STAR certified models.
