FAQs
How does a tankless water heater save energy compared to a traditional storage tank model?
Traditional water heaters keep 40–80 gallons of water hot 24/7, which creates standby heat losses. A tankless unit heats water only when a fixture calls for it, eliminating standby losses. In most homes, this can cut water-heating energy use by 24–34 %, and even more if you install low-flow fixtures or insulate hot-water lines.
Is a tankless water heater powerful enough for a large household in Allardt?
Yes—provided it’s sized correctly. We calculate the maximum gallons per minute (GPM) you’ll need during peak demand (for example, two showers and a washing machine at once). Then we match that GPM to a unit that can raise incoming Allardt groundwater (about 55 °F) to your desired outlet temperature (usually 120 °F). For households of 3–5 people, we typically recommend a 7–10 GPM gas model or two 5-GPM electric units in parallel.
What’s involved in the installation process and how long does it take?
A typical residential install in Allardt takes one working day. We (1) decommission and remove the old tank, (2) mount the compact tankless unit to a wall, (3) upsize gas or electrical service as needed, (4) run new venting or wiring per code, (5) add isolation valves and a condensate drain, and (6) test for leaks and proper flow/temperature. Permitting and utility inspections may add 1–2 extra days, but your hot water is usually restored the same day.
Will switching to tankless lower my monthly energy bills enough to justify the upfront cost?
Most households see water-heating bills drop $80–$150 per year. Gas tankless units cost about $1,500–$2,800 installed, while electric models run $900–$1,800. With average savings, payback is 6–10 years—often shorter when you combine lower energy use with local utility rebates (TVA and Jamestown Electric both offer $200–$400 incentives) and possible federal tax credits of 10 % of the project cost.
What maintenance does a tankless water heater require in this part of Tennessee?
Allardt’s water is moderately hard (6–8 grains/gallon). To keep efficiency high, flush the heat exchanger with white vinegar or a descaling solution once a year (takes about 45 minutes). We install isolation valves to make that simple. Also clean the inlet filter quarterly and have a technician inspect the burner or elements every 2–3 years. Routine maintenance can extend service life to 20 years or more.
Are there any special plumbing or electrical upgrades I should budget for?
Gas models often need a ¾-inch gas line and Category III or IV stainless venting. Expect $200–$600 for gas line upsizing if your current run is only ½-inch. Electric tankless units may require a 200-amp service panel and dedicated double-pole breakers (in the 60–120 amp range). If your home has a 100-amp panel, factor in $1,000–$2,000 for a service upgrade. We provide an on-site evaluation so you know exact costs before committing.
