FAQs
What are the main benefits of choosing a high-efficiency tankless water heater for my Rogersville home?
High-efficiency tankless units heat water on demand, so you never run out of hot water and don’t pay to keep a storage tank hot all day. They typically cut energy use by 25–40 %, last 20+ years (almost twice the life of a tank), free up floor space, and qualify for utility rebates and federal tax credits that can lower the upfront cost.
How long does a professional installation usually take?
Most residential replacements are completed in one day. We start by disconnecting and removing your old tank, size and mount the new wall-hung unit, run the upgraded gas line or electrical circuit, add condensation and vent piping to code, and test the system. Complex retrofits—such as moving the heater to another wall or repiping multiple bathrooms—can add a half day.
Will my existing gas line or electrical service need to be upgraded?
Probably. High-efficiency gas models require a larger ¾″ gas line and a 110-V outlet for the condensate pump, while electric models need a 240-V circuit with 40–60 amp breakers. During your free Rogersville in-home estimate, we measure supply pressure and panel capacity so you know upgrade costs before work begins.
How much can I expect to save on my utility bills?
Savings depend on usage, but Rogersville customers switching from a standard gas tank average $100–$150 off their annual gas bill; electric switch-overs see 20–30 % lower power costs. Because the unit fires only when you open a hot-water tap, you eliminate the 24/7 standby losses associated with storage tanks.
What maintenance does a tankless system require?
Once a year our technicians perform a 45-minute tune-up: flush the heat exchanger with food-grade vinegar to remove mineral scale, clean the air intake filter, inspect the burner, and test safety sensors. With Rogersville’s moderately hard water, descaling is essential to keep efficiency high and protect your 15-year parts warranty.
Do I need permits or inspections in Rogersville?
Yes. Lauderdale County requires a mechanical permit for fuel-gas or electric water-heating equipment. We pull all permits, schedule the final inspection, and provide you with a passing inspection sticker and warranty registration documents when the job is complete.
