FAQs
What are the main advantages of switching from a traditional storage‐tank heater to a tankless water heater?
Tankless units heat water on demand, so you get virtually endless hot water and eliminate standby heat loss, which can reduce energy use by 25–40 %. They mount on the wall, freeing up floor space, and last 18–20 years—about twice the lifespan of a tank model. Most brands also offer longer warranties, and local utility rebates for high-efficiency models can further offset the upfront cost.
How long does a licensed plumber need to install a tankless water heater in Strawberry Plains?
For a straightforward replacement, our licensed team typically completes the job in 3–6 hours. That includes removing the old tank, mounting the new unit, upgrading venting, rerouting water and gas/electrical lines as needed, testing the system, and hauling away debris. More complex projects—such as relocating the heater, upsizing the gas line, or adding a dedicated electrical circuit—may extend the job to a full day. We always give you a detailed timeline before work begins.
Will I have to upgrade my gas, propane, or electrical service to run a tankless unit?
It depends on the model and your home’s existing infrastructure. Gas tankless heaters often need a ¾-inch gas line and Category III or IV stainless steel venting. Electric models may require a 120–200 amp service panel and dedicated 30–60 amp breakers. During your free in-home assessment, we measure gas pressure, check wire gauge, and calculate load to determine whether upgrades are necessary. If they are, we handle all permitting and code compliance for you.
How do I know what size (flow rate) tankless water heater my household needs?
Sizing is based on simultaneous demand, measured in gallons per minute (GPM), and required temperature rise. We add up the flow rates of fixtures you’re likely to run together—shower (2.5 GPM), dishwasher (1.5 GPM), washing machine (2.0 GPM), etc.—then calculate how much the heater must raise incoming groundwater (typically ~55 °F in Strawberry Plains) to your desired set point (120 °F). A typical 3-bath home needs 7–9 GPM; larger families or luxury bathrooms may need 11 GPM or a multi-unit cascade setup. Our plumbers perform this calculation during your consultation to recommend the right model.
What routine maintenance does a tankless water heater require, and do you provide the service?
All manufacturers recommend descaling the heat exchanger every 12 months in areas with moderate to hard water—Strawberry Plains averages 7–10 grains per gallon—plus cleaning the inlet filter and checking venting. Neglecting maintenance can void the warranty and reduce efficiency. We offer affordable annual service plans that include flushing with food-grade vinegar, full diagnostic testing, and firmware updates for smart models. We also keep digital records for warranty validation.
Are your plumbers fully licensed and insured to install tankless water heaters in Tennessee?
Yes. Every technician who enters your home carries a current Tennessee Limited Licensed Plumber (LLP) or Journeyman Plumber license, is OSHA-10 certified, and is bonded and insured for both general liability and workers’ compensation. We pull all required permits for Strawberry Plains, coordinate any utility inspections, and back our workmanship with a 100 % satisfaction guarantee and a 5-year labor warranty in addition to the manufacturer’s parts warranty.
