FAQs
What advantages does a tankless water heater offer compared with a traditional tank model?
A properly sized tankless water heater heats water only when a fixture calls for it, eliminating standby heat loss and often cutting energy costs 20–40 %. Because there is no bulky storage tank, you free up several square feet of floor space. Tankless units also last longer—-typically 20 years or more versus 8–12 years for a tank. Finally, you get an endless supply of hot water—great for large families or back-to-back showers—so long as the unit’s flow-rate matches your household demand.
How do I determine the correct size (flow-rate, or GPM) for my Maynardville home?
Sizing is based on the total gallons per minute (GPM) you expect to use at one time and the temperature rise required. We start by adding up the flow rates of fixtures that might run simultaneously—e.g., a shower (2.0 GPM) + washing machine (2.5 GPM) = 4.5 GPM. Maynardville’s incoming water averages about 55 °F. If you want 120 °F hot water, you need a 65 °F rise. A unit that can deliver at least 4.5 GPM at a 65 °F rise would be recommended. During your estimate, our licensed plumber confirms fixture counts, peak-use habits, gas supply, and electrical capacity to pick the right model.
Does Maynardville’s water quality require any special considerations for tankless units?
Parts of Union County, including Maynardville, have moderately hard water (5–7 grains per gallon). While this is not extreme, scale can accumulate inside the heat exchanger over time and reduce efficiency. We install an isolation-valve service kit and, when advisable, a scale-inhibiting pre-filter. We also recommend a quick annual flush with white vinegar or manufacturer-approved descaler—usually a 30-minute service call—to keep the warranty valid and performance optimal.
Can a tankless water heater tie into my existing venting, gas, or electrical lines?
Sometimes. Gas-fired tankless units need a larger BTU input (150–199 k BTU) and therefore may require upsizing the gas line from ½-inch to ¾-inch. High-efficiency condensing models use 2-in. PVC venting, which is often simpler than the Category III stainless venting used on older units. Electric tankless heaters typically need a 240-V supply with multiple 40- or 50-amp breakers. During the on-site survey we verify line sizes, meter capacity, and vent paths; if upgrades are necessary we give a firm quote before work begins.
How long will installation take and what should I expect on the day of service?
Most swap-outs of an existing tank for a gas tankless unit take 6–8 hours. We shut off utilities, drain and remove the old tank, mount the new unit on the wall, run any new gas or water lines, install the venting, and wire the control panel. Before we leave, we pressure-test, purge air from the lines, check for gas leaks, and walk you through operating the digital controller. Your water will be off for 2–4 hours; plan laundry or showers accordingly. We haul away the old tank and job-site debris at no extra charge.
What maintenance and warranty support do you provide after installation?
All units we install carry the manufacturer’s standard 12- or 15-year heat-exchanger warranty, 5-year parts, and 1-year labor. We extend the labor coverage to 3 years for customers who enroll in our annual maintenance plan, which includes descaling, filter changes, and a full performance check each spring. Even without the plan, we send a free annual reminder so you don’t miss required maintenance that could void the warranty. Our 24/7 emergency hotline covers leaks, ignition faults, or any post-install concerns in the Maynardville area.
