FAQs
How does a tankless water heater produce hot water without a storage tank?
When a hot-water tap is opened, cold water travels through a heat exchanger inside the wall-mounted unit. A gas burner or electric element fires up only at that moment, quickly heating the water to the set temperature as it flows by. When the tap closes, the burner shuts off, so the system avoids the standby heat loss typical of traditional storage tanks.
Why are tankless water heaters a good choice for homes in Walland, TN?
1. Energy efficiency – Walland’s mild winters mean the incoming water temperature is not extremely cold, letting the heater reach setpoint faster and use less fuel. 2. Endless hot water – Great for cabins or vacation rentals near the Foothills Parkway where guest demand can spike. 3. Space savings – Many Walland homes have limited mechanical-room space; a tankless unit mounts on a wall and frees up square footage. 4. Longer life – With proper maintenance, units last 20+ years, outliving a standard tank by almost a decade. 5. Local utility incentives – Sevier County Energy Smart Program and TVA often offer rebates for ENERGY STAR® tankless models, lowering installation costs.
How do I determine the correct size (capacity) of a tankless unit for my household?
Sizing is based on two factors: 1) the maximum flow rate your home needs during peak demand (measured in gallons per minute, or GPM) and 2) the required temperature rise (difference between ground-water temperature and desired output). In Walland the groundwater averages 55-58 °F; if you want 120 °F water, you need roughly a 62 °F rise. Add up the GPM of fixtures you might use simultaneously—for example a shower (2.0 GPM) plus dishwasher (1.5 GPM) equals 3.5 GPM. We’ll recommend a unit that can supply at least that flow at a 62 °F rise, typically 160–199 k BTU/hr for gas models or 27–36 kW for electric models.
Will my existing gas line, venting, or electrical service need to be upgraded?
Possibly. High-efficiency gas units usually require a ¾-inch gas line and Category III or PVC concentric venting through an exterior wall or roof. Older homes in Blount County sometimes have only a ½-inch gas supply that must be upsized. Electric units above 18 kW need 150- to 200-amp service and two to four dedicated double-pole breakers. During your free on-site estimate we measure pipe sizes, check panel capacity, and provide a written quote that includes any plumbing, venting, or electrical upgrades so there are no surprises.
What is the average cost to install a tankless water heater in the Walland area, and are rebates available?
For a typical three-bathroom home, a professionally installed gas tankless system runs $3,000–$4,500, including removal of the old tank, vent kit, gas-line upsizing, and local permit fees. Electric models cost $2,200–$3,200 but may require panel upgrades. TVA’s EnergyRight® program and the Sevier County Electric rebate can provide $200–$500 back on qualifying ENERGY STAR units, while gas utilities like Atmos occasionally offer bill credits. We file all rebate paperwork on your behalf to maximize savings.
What kind of maintenance does a tankless water heater require and how often?
Tankless units need far less attention than storage tanks but do benefit from annual service: • Descale the heat exchanger with a vinegar or citric-acid flush to remove mineral buildup—especially important because Walland’s water hardness averages 5–8 grains per gallon. • Clean the inlet screen filter and condensate trap (on condensing models). • Inspect the burner, fan, and vent system; clear any debris. • Check combustion settings with a digital analyzer to ensure peak efficiency. Our plumbing team offers a yearly maintenance plan that keeps your warranty valid, extends equipment life, and includes priority scheduling in case of an unexpected issue.
