FAQs
How does a tankless water heater save energy compared to a conventional storage-tank model?
A tankless unit heats water only when you open a tap, so there is no standby heat loss from keeping 40–50 gallons hot all day. High-efficiency gas models can reach 96–98 % thermal efficiency and modulate their burner output to match demand, using 24–34 % less energy for a typical family and up to 50 % less for homes with low daily hot-water use. Because the heater shuts off the instant you close the faucet, it also eliminates the short-cycling that wastes fuel in older tanks.
Is a tankless water heater a good choice for homes in Crab Orchard?
Yes. Crab Orchard’s moderate four-season climate is well within the operating range of today’s units, which include built-in freeze protection down to –30 °F for exterior models. Local water hardness is only moderate, so an annual flush is all that is normally required to prevent scale. Our technicians are licensed in Tennessee/West Virginia (depending on which Crab Orchard you’re in) and familiar with local plumbing, gas and electrical codes, so your installation meets all municipal requirements.
What size tankless unit will my household need?
Sizing is based on peak flow rate and desired temperature rise. We total the gallons per minute (GPM) of the fixtures you might use at the same time—e.g., two showers (2.5 GPM each) plus a kitchen sink (1.5 GPM) equals 6.5 GPM. With the average incoming water temperature in Crab Orchard around 55 °F and a target of 120 °F, you need a 65 °F rise. A gas unit rated at 8–10 GPM @ 65 °F rise will comfortably handle a 2- to 3-bath home. Electric models require 15–20 kW for the same load, so we’ll verify your service panel capacity during the estimate.
How long does installation take and will I need plumbing or gas upgrades?
Most replacements are completed in one day—about 4–6 hours for gas and 6–8 hours for electric—after any required permits are issued. We may upsize the gas supply line to ¾″ or 1″ black iron and install stainless-steel Category III venting for condensing units. Electric models sometimes need a 200-amp service upgrade or a dedicated breaker. All water connections are re-piped with isolation valves to make future maintenance easy. We provide a written estimate before any work begins.
What routine maintenance does a tankless water heater require, and do you service what you install?
An annual 45-minute flush with white vinegar or manufacturer-approved descaler removes mineral buildup and keeps the heat exchanger efficient. The inlet screen filter should be rinsed every 6–12 months. That’s it—no anode rods to replace. We offer a low-cost maintenance plan that includes the flush, full diagnostic check and firmware updates. Our Crab Orchard team is factory-trained for Rinnai, Noritz, Navien, Rheem and Stiebel Eltron, so warranty repairs are handled locally without shipping parts away.
How much money can I expect to save and are rebates available in Crab Orchard?
Homeowners typically cut water-heating costs 10–30 %, or about $80–$150 per year on a $900 gas bill, and even more if you retire an old electric tank. Payback is 5–7 years for most families. A 30 % federal tax credit (up to $600) is available through 2032 for ENERGY STAR-qualified models, and many utility customers in the Crab Orchard area can claim an additional $150–$250 rebate through Appalachian Power/TVA. We handle the paperwork so you receive every incentive you qualify for.
