FAQs
What are the main benefits of installing a high-efficiency tankless water heater in Strawberry Plains?
Tankless units provide hot water on demand, so you never run out during showers or laundry. Because they heat water only when you open a fixture, they can cut energy use by 25–40 % compared with a standard storage-tank heater. Most models are wall-mounted, freeing up floor space, and their average life span (20+ years) is almost double that of conventional tanks. High-efficiency models also qualify for state and federal rebates, which helps offset the initial cost. Our licensed techs ensure each installation meets Tennessee mechanical and plumbing codes, giving you safe, reliable hot water year-round.
How long does a typical tankless water heater installation take?
For most homes in Strawberry Plains, a straightforward replacement with existing gas or electric service takes 4–6 hours. If upgrades are needed—such as upsizing a gas line, adding a dedicated 240-V circuit, or relocating venting—the job can extend to a full day. We start with a pre-installation inspection to identify any code or capacity issues, give you a time estimate, and schedule a convenient appointment. All work is done in one visit whenever possible, and your water service is usually interrupted for less than two hours.
Will a tankless water heater really lower my utility bills?
Yes. Traditional tanks keep 40–50 gallons hot 24/7, wasting standby energy. A tankless unit only fires when a tap opens, so no standby loss occurs. ENERGY STAR® data show that an average household using 41 gallons of hot water daily can save about $100 per year with a gas tankless model; heavier-use households can save even more. Electric tankless units eliminate standby loss completely and can trim 8–15 % off your electric bill. Local utility rates in Strawberry Plains and actual hot-water usage ultimately determine savings, but most customers see payback within 5–7 years.
What size (flow rate) tankless unit do I need for my home?
Sizing depends on two factors: (1) total flow rate of fixtures you may run simultaneously and (2) the required temperature rise from your incoming cold-water temperature to your desired hot-water setting. In Strawberry Plains, groundwater averages 55 °F. To reach 120 °F, you need a 65 °F rise. A couple who usually runs one shower (2.0 gpm) and a dishwasher (1.5 gpm) at the same time needs about 3.5 gpm at that rise—around a 140,000 BTU gas unit or a 24 kW electric model. Larger families or homes with soaking tubs may need 7–9 gpm units. Our technicians calculate these numbers during your free estimate to ensure you never experience a cold-water sandwich.
Will I need to upgrade my gas line or electrical service?
Possibly. High-efficiency gas tankless units often require ¾-in. gas supply lines and 150,000–199,000 BTU input, more than many older homes provide. We pressure-test and measure existing gas lines; if they are undersized, we can run a new line from your meter. Electric tankless units typically need 100–150 A of dedicated capacity plus multiple double-pole breakers. Homes with 100-A main panels may require a service upgrade to 200 A. We handle permitting, utility coordination, and all code-required inspections so the installation is safe and compliant.
How often does a tankless water heater require maintenance and what does it involve?
Manufacturers recommend annual maintenance in areas with moderate to hard water, like Strawberry Plains. Service includes descaling the heat exchanger with food-grade vinegar or a citric-acid solution, cleaning the inlet filter, checking the burner or heating elements, and verifying exhaust venting and gas pressures. The process takes about an hour. Regular maintenance prevents mineral buildup that can reduce efficiency and trigger error codes, and it keeps your warranty valid—most brands require documented service records to honor heat-exchanger warranties of 10–15 years.
