FAQs
What are the main benefits of switching to a tankless water heater in Heiskell?
A tankless (on-demand) unit heats water only when you open a tap, so you eliminate standby heat loss and can cut water-heating energy use by 25-40 %. Homeowners in Heiskell also appreciate the endless hot-water supply for long showers, the wall-mounted space-saving design, and life expectancies that typically run 20+ years—about double that of a storage tank heater.
How do I determine the correct size (flow rate) tankless unit for my home?
Sizing is based on two factors: (1) the maximum number of fixtures you might run simultaneously and (2) the temperature rise between incoming groundwater and your desired hot-water setpoint. In the Heiskell area, groundwater averages 55–60 °F, so a 60 °F rise gives 115-120 °F at the tap. We’ll total the flow rates of those fixtures (e.g., 2.5 gpm shower + 1.5 gpm sink) to recommend a unit that can deliver 4-5 gpm at a 60 °F rise. Our technician performs this calculation during the free in-home estimate to make sure you never run out of hot water.
Will a tankless water heater work with my existing plumbing and gas or electric service?
In most cases, yes, but some upgrades may be needed. Gas models require a larger gas line (¾" is common) and a Category III or IV stainless-steel vent through an exterior wall or roof. Electric models often need a 120- to 200-amp service panel with multiple 40-50-amp breakers. During our site visit we verify line sizes, electrical capacity, venting paths, and water-line conditions so you know exactly what, if anything, needs to be modified before installation.
What is involved in a professional tankless installation and how long does it take?
On installation day we (1) drain and remove your old tank, (2) mount the new tankless unit, (3) run or upsize gas/electric lines, (4) install the sealed vent or condensate drain, (5) connect hot- and cold-water lines with isolation valves, and (6) commission the heater to factory specs. A straightforward retrofit in Heiskell typically takes 5–7 hours; jobs requiring panel upgrades or long gas runs may extend to a full day. We always haul away the old tank and leave the workspace clean.
Are permits, codes, or rebates required for tankless installations in Heiskell?
Yes. Anderson County and the State of Tennessee plumbing/mechanical codes require a permit and final inspection for gas or electric water-heater replacements. Our licensed plumbers pull the permit for you and coordinate with the inspector so you don’t have to. Tennessee Valley Authority (TVA) periodically offers rebates, and certain ENERGY STAR® models may qualify for a federal tax credit of up to 30 % (subject to annual limits). We’ll walk you through current incentives at the time of your estimate.
How do I maintain my new tankless water heater and what warranty is included?
The key maintenance task is descaling the heat exchanger once a year (every 6 months if you have hard water). We install isolation valves so you can flush the unit yourself with white vinegar, or we can handle it during an annual service visit. Most leading manufacturers give 12- to 15-year heat-exchanger warranties, 5-year parts warranties, and 1-year labor coverage. Our company extends the labor warranty to 3 years when you enroll in our maintenance plan.
