FAQs
What are the main benefits of switching to a tankless water heater in Luttrell?
A tankless unit heats water only when you turn on a tap, so it can cut energy use by 25–40 % compared with a traditional tank. You also get endless hot water, a system that takes up far less space, and a life expectancy of 20+ years (about twice that of a storage tank). Because there’s no stored water, there’s virtually no risk of tank leaks or the standby heat loss that raises utility bills.
How does a tankless water heater actually work?
When you open a hot-water fixture, a flow sensor tells the unit’s computer to ignite the gas burner or energize the heating elements. Cold water passes through a tightly coiled heat exchanger and comes out at the set temperature—usually within a few seconds. Once you close the tap, the burner or elements shut off, eliminating the constant reheating that a tank requires.
Will a single tankless water heater provide enough hot water for my whole house?
Yes—if the unit is properly sized. We calculate the maximum hot-water demand in gallons per minute (GPM) for your fixtures and appliances, then match that to a model’s rated flow at Luttrell’s winter groundwater temperature (about 50 °F). Larger homes sometimes need two units or a dedicated point-of-use heater for high-flow fixtures like a spa tub. During your estimate, we’ll measure your usage and recommend the right capacity.
What is involved in a professional tankless water heater installation and how long will it take?
Most retrofits take 4–8 hours. We start by turning off utilities and draining the old tank. Next, we mount the compact tankless unit on a wall and run new water, gas or electric, and condensate lines as needed. High-efficiency gas models require stainless-steel or PVC venting, which we install through an exterior wall or roof. Finally, we program the thermostat, test for leaks, and flush the system. You’ll have hot water before we leave.
What kind of maintenance does a tankless water heater need?
To maximize efficiency and warranty coverage, flush the heat exchanger with a vinegar or descaling solution once a year to remove mineral buildup—especially important with Luttrell’s moderately hard water. Clean the inlet filter quarterly, and check the vent and condensate drain for obstructions. Most homeowners schedule an annual service visit, which takes about an hour and keeps the unit running like new.
Are there energy rebates or tax credits available for tankless water heaters in Luttrell?
Yes. ENERGY STAR–qualified gas tankless units typically qualify for a federal tax credit of 30 % of the project cost, up to $600 (consult IRS Form 5695 for current limits). Knoxville Utilities Board and other local providers sometimes offer $100–$300 rebates for high-efficiency equipment. Because a tankless model can cut your water-heating bills by up to 40 %, most residents recoup the upgrade cost in 3–5 years even without incentives.
