FAQs

What size tank water heater do I need for my Strawberry Plains home?

A rough guideline is 30–40 gallons for 1–2 people, 40–50 gallons for 2–3 people, 50–60 gallons for 3–4 people, and 75+ gallons for larger households. However, your exact requirement should be based on your peak‐hour demand (the total gallons of hot water used during the busiest 60-minute period). Our technicians calculate this figure, look at groundwater temperature in Strawberry Plains (averaging 55–60 °F), and apply the DOE’s First Hour Rating (FHR) standard to recommend the right tank size.

Are storage-tank water heaters still energy-efficient?

Yes. New federal regulations under the U.S. Department of Energy (DOE) set minimum Uniform Energy Factor (UEF) ratings that every tank unit sold in Tennessee must meet. Modern gas units typically achieve a UEF of 0.60–0.72, while electric models reach 0.90 or higher. High-efficiency condensing gas tanks can exceed 0.80. We also insulate tanks to at least R-8 per ASHRAE 90.1 requirements and install heat traps and low-restriction dielectric unions to minimize standby losses.

How often should my tank water heater be serviced?

Industry best practice—endorsed by the American Water Works Association (AWWA)—calls for annual maintenance: 1) flush sediment to prevent scale buildup, 2) test the temperature-pressure relief (TPR) valve, 3) inspect and replace the anode rod every 3–5 years, 4) check the gas burner or electric elements, 5) verify expansion tank pressure, and 6) set thermostat to the ANSI-recommended 120 °F. Regular service extends life, keeps your warranty valid, and ensures compliance with local plumbing codes adopted by Knox, Jefferson, and Sevier counties.

Do I need a permit to replace a tank water heater in Strawberry Plains?

Yes. All water heater installations in Strawberry Plains require a plumbing permit from the county in which the property is located (Knox County Codes Administration & Inspection, Jefferson County Building Department, or Sevier County Building & Codes). Gas units additionally require compliance with NFPA 54 (National Fuel Gas Code), including proper combustion air, venting, and seismic strapping. We pull the permit, schedule the inspection, and provide you with final approval paperwork.

Should I choose gas or electric for my new tank water heater?

Gas models heat water faster and usually cost less to operate when natural gas is available (roughly $150–$200 per year). Electric units cost more to operate ($300–$450 per year) but are cheaper to buy, simpler to install, and require no venting. If your home is on propane or has no gas line, electric is often the practical choice. We evaluate energy prices in Strawberry Plains, existing utilities, ventilation options, and your household’s hot‐water needs to recommend the most cost-effective solution.

What is the typical lifespan and warranty coverage for a tank water heater?

Standard residential tank water heaters last 8–12 years, while premium units with thicker glass lining and dual anode rods can last 12–15 years. Manufacturer warranties in 2024 range from 6 years (entry-level) to 12 years (premium). Routine maintenance documented by a licensed plumber—flushing, anode replacement, pressure checks—helps you reach or exceed the rated lifespan and protects coverage under Rheem, Bradford White, A.O. Smith, and State warranty terms.
