FAQs
How long does a tankless water heater installation usually take in Allardt?
Most standard residential installations are completed in a single day (4-8 hours). This time frame covers removing the old tank, hanging and venting the new tankless unit, making gas or electrical upgrades, reconnecting water lines, flushing the system, and performing the final start-up test. Homes that need a larger gas line, a longer vent run, or an electrical service upgrade may require an extra half-day. We schedule an on-site pre-inspection so you’ll receive a precise timeline before any work begins.
Do I need a building permit or inspection for a tankless conversion in Allardt?
Yes. The City of Allardt and Fentress County both treat a tank-to-tankless swap as a plumbing and (if gas-fired) mechanical alteration. We pull the required permit on your behalf, coordinate with the local inspector, and include the small permit fee in your written quote. On the day of installation our licensed plumber will arrange the rough-in or final inspection so your new heater is 100 % code-compliant and protected by manufacturer warranty.
What size (flow rate) tankless water heater should I choose?
Sizing is based on two factors: 1) the combined gallons-per-minute (GPM) demand of fixtures you might use at the same time, and 2) the temperature rise needed to heat incoming Allardt groundwater (about 55 °F) to your desired setpoint (typically 120 °F). For most three-bathroom homes a 9–11 GPM unit (199,000 BTU gas or 27 kW electric) is appropriate. During our site visit we’ll test your water pressure, count fixtures, and recommend the exact model that ensures endless hot water without overspending on capacity.
Can my existing gas, electric, and venting systems support a tankless unit?
Often, but not always. Gas models require a ¾-inch or 1-inch gas line capable of 150–199 k BTU, plus Category III/IV stainless or PVC venting. Electric models need 240 V service and two or three dedicated 40- to 60-amp breakers. During our free assessment we measure gas pressure, inspect your electrical panel, and plan the vent route. If upgrades are necessary, we quote them up front so there are no surprises.
What routine maintenance does a tankless water heater need?
All manufacturers recommend an annual service: flushing the heat exchanger with a 5 % white-vinegar solution or food-grade descaling agent to dissolve mineral buildup, cleaning the inlet filter, and checking ignition components. In Allardt’s moderately hard water (about 5–7 grains per gallon) this 45-minute procedure maximizes efficiency and preserves the heat exchanger warranty. We offer economical maintenance plans or can show DIY-inclined homeowners how to perform the flush themselves.
How much does installation cost and are rebates available?
Installed pricing in Allardt ranges from $2,200–$3,800 for gas units and $1,900–$3,200 for electric units, depending on capacity, vent length, and utility upgrades. TVA (Tennessee Valley Authority) customers may qualify for up to a $300 electric water-heating incentive, and some natural gas providers offer $150–$250 rebates for ENERGY STAR certified units. We handle the paperwork and deduct approved rebates from your final invoice to lower out-of-pocket costs.
