FAQs
What are the main benefits of switching to a tankless water heater for my Strawberry Plains home?
A properly sized tankless unit delivers endless hot water on-demand, saves 20–40 % in energy costs compared with a storage tank, frees up valuable floor space, and typically lasts 18–20 years—almost twice as long as a conventional heater. In Strawberry Plains, where groundwater temperatures average in the mid-50 °F range, modern high-efficiency units can achieve energy factors (UEF) above 0.90, meaning lower utility bills all year. In addition, many utility providers in East Tennessee offer rebates for high-efficiency tankless installations.
How long does a typical tankless water heater installation take?
Most residential installations are completed in one working day. The process involves draining and removing the old tank, upgrading or rerouting gas/electric and water lines, mounting the new unit, installing venting, and performing start-up diagnostics. If substantial gas line upsizing, electrical work, or vent routing through masonry is required, the project can extend to a second day, but we always provide a time estimate after the on-site assessment.
Can a tankless water heater run on my existing natural gas, propane, or electric service?
Often, yes—but a quick load calculation is needed to be sure. Gas tankless models require a ¾″ (or sometimes 1″) gas line and up to 199,000 BTU/h input. Many Strawberry Plains homes built before 2000 have ½″ gas piping, so we verify capacity and upsizing needs during our estimate. If you use propane, we confirm that your regulator delivers at least 11" WC pressure. Electric tankless units usually need 100–120 amps of dedicated 240-V capacity, which can exceed older 100-amp service panels. We review your panel rating and offer upgrade options if necessary.
What size tankless water heater do I need?
Sizing is based on peak hot-water demand (gallons per minute) and the temperature rise required from incoming groundwater to your desired outlet temperature. In Strawberry Plains, incoming water averages 55 °F. If you want 120 °F water, that’s a 65 °F rise. For a family that might run two showers (2.0 GPM each) and a dishwasher (1.5 GPM) simultaneously, you’d need about 5.5 GPM at a 65 °F rise. We perform a detailed load calculation during our visit and recommend the right model so you never run out of hot water.
Are permits or inspections required for a tankless water heater installation in Strawberry Plains, TN?
Yes. Jefferson County (for areas west of the Holston) and Knox County (for areas inside the Knox line) both require mechanical and, if gas is involved, fuel-gas permits. The local municipality or county inspector will verify venting clearances, combustion air, gas-line sizing, electrical bonding, and pressure relief provisions. Our licensed plumbers obtain the permits, schedule the inspections, and provide you with the final signed-off paperwork for your records.
How much maintenance does a tankless water heater need and do you offer service plans?
Tankless units need an annual 45-minute flush with food-grade vinegar or citric solution to remove scale, plus a quick filter cleaning if your model has one. Hard water in Strawberry Plains (12–14 grains per gallon) makes yearly descaling essential to preserve efficiency and warranty coverage. We offer a low-cost maintenance plan that includes the flush, a combustion check, and diagnostic code scan. Plan members receive priority scheduling and discounted parts should any repairs be needed.
