FAQs
What are the main benefits of switching to a tankless water heater in Sharps Chapel?
Tankless (on-demand) water heaters heat water only when you need it, eliminating standby heat loss from a storage tank. In Sharps Chapel, this typically results in energy savings of 20–40 %, longer equipment life (20+ years vs. 8–12 for a tank), unlimited hot-water supply for back-to-back showers, and space savings because the wall-mounted units free up floor area. They are also eco-friendly, producing lower greenhouse-gas emissions and qualifying many homeowners for local utility or federal tax incentives.
How does the installation process work with your Sharps Chapel plumbing team?
1) We start with a free in-home assessment of your hot-water demand, gas line size, venting route, and electrical capacity. 2) You receive a written quote outlining the exact scope, model options, and any code upgrades required by Union County. 3) On installation day we drain and remove the old tank, mount the new tankless unit, upsize gas or propane lines if needed, install Category III/IV stainless venting, add a condensate drain, and integrate the unit into your existing hot- and cold-water piping. 4) Finally, we pressure-test the lines, flush the heater, program temperature settings, pull any required permits, and demonstrate operation before clean-up.
Will my current gas, propane, or electrical service handle a tankless unit?
Most tankless gas models need a ¾-inch gas supply and up to 199,000 BTU/h. If your home currently uses a ½-inch line or a small propane regulator, we’ll quote an upsizing to meet manufacturer specs and Tennessee mechanical code. Electric tankless units often require 150–200 amp service with multiple 40-50 amp double-pole breakers; we’ll check your panel and recommend upgrades if necessary. Our licensed plumbers and electricians coordinate any service changes so your new heater runs safely and efficiently.
What size (GPM) tankless water heater do I need for my household?
We size units by peak gallons per minute (GPM) flow. A typical Sharps Chapel household with two bathrooms, a dishwasher, and a washing machine needs 6–8 GPM at a 70 °F temperature rise (incoming well water averages 55 °F). Larger families with simultaneous showers may need 9–11 GPM or dual-unit cascading. During the site visit we calculate your exact demand and propose models that maintain 120 °F output without temperature drop.
How much does a professional tankless installation cost, and are there rebates for Sharps Chapel residents?
Installed pricing usually ranges from $3,200 to $4,800 for a standard natural-gas condensing unit, depending on gas line length, venting route, and whether electrical or water-softening upgrades are needed. Electric whole-house units average $2,800 to $3,600. TVA’s EnergyRight program often offers $100–$300 rebates, and qualifying ENERGY STAR® units may earn a 30 % federal tax credit (up to $600). We handle all paperwork and show you the payback period based on your current utility rates.
What maintenance does a tankless water heater require and how long will it last?
Annual maintenance is simple: we flush the heat exchanger with food-grade vinegar to remove mineral scale (especially important with Sharps Chapel’s moderately hard water), clean the inlet screen, and perform a combustion analysis. This service takes about 60 minutes and prevents efficiency loss or error codes. With proper care, a quality stainless-steel condensing unit lasts 20–25 years—roughly twice the lifespan of a conventional tank. We offer affordable maintenance plans and 24/7 support if any issue arises.
