FAQs
What are the main benefits of switching to a tankless water heater in Strawberry Plains?
Tankless (on-demand) water heaters heat water only when you open a tap, so you never run out of hot water and you avoid the standby heat loss of a storage tank. In Strawberry Plains, where energy costs trend higher than the national average, homeowners typically see 25–40 % savings on their gas or electric bills. A tankless unit is wall-mounted, freeing up 10–15 sq ft of floor space, lasts 20+ years (almost double a tank model), and reduces the risk of tank leaks and flooding. Many models also qualify for federal tax credits and local utility rebates.
How do I determine the correct size (flow rate) for my home?
Sizing is based on simultaneous demand—the total gallons per minute (GPM) of hot water you need at peak usage. Add up the flow rates of the fixtures you may run together (e.g., shower 2.5 GPM + dishwasher 1.5 GPM + sink 1 GPM = 5 GPM). Then factor in the temperature rise: in Strawberry Plains the incoming water is about 55 °F, so a 60 °F rise gets you to a 115 °F shower. Most 2-to-3-bath homes need a 7–9 GPM gas unit (180–199 k BTU) or an 18–27 kW electric model. Our technicians perform a free site evaluation and load calculation to recommend the exact size for your household.
What does the installation process involve and how long will it take?
After the initial assessment, we secure the permit and schedule a convenient install date. On install day we: 1. Drain and remove the old tank (30–60 min). 2. Upgrade the gas line to ¾″ (or size the electric circuit/breaker) as required (1–3 hrs). 3. Mount the tankless unit on an exterior or interior wall and run stainless-steel venting or concentric PVC through the roof or sidewall (1–2 hrs). 4. Connect cold/hot water lines with isolation valves, add a condensate drain, and install a sediment filter if needed (1 hr). 5. Pressurize, purge air, program the controller, and demonstrate operation (30 min). Most straightforward gas installs are completed in 4–8 hours; jobs needing long vent runs or major gas upgrades can stretch to two days.
Do I need a permit, and will the installation meet local codes?
Yes. Knox, Jefferson, and Sevier Counties require a mechanical/plumbing permit for water-heater replacements, and gas work must be performed by a licensed contractor. We obtain the permit, coordinate the inspection, and ensure the job adheres to the International Fuel Gas Code (IFGC), UPC, and the specific clearance/venting rules adopted by Strawberry Plains. Typical code checkpoints include a gas pressure test, proper vent termination (at least 3 ft from doors or windows), a bonding jumper on metal piping, and an accessible electrical disconnect.
What maintenance does a tankless water heater need in this area?
Strawberry Plains has moderately hard water (8–12 grains per gallon), so mineral scale can build up on the heat exchanger. Manufacturers recommend flushing the unit with a 4-gallon vinegar or citric-acid solution once a year (every 6 months if hardness is above 12 gpg). You should also: clean the inlet screen filter quarterly, inspect the vent and condensate line annually, and check for error codes on the controller. We offer an affordable annual service plan that includes descaling, filter cleaning, and a full diagnostic check to protect your warranty.
How much does a tankless installation cost and are there rebates or financing?
Installed pricing depends on fuel type, size, and site conditions. In Strawberry Plains you can expect: • Natural-gas/propane unit: $3,200–$5,500 installed (includes vent kit, isolation valves, and minor gas line extension). • Electric unit: $2,200–$3,500 installed (includes breaker, wiring, and required shut-off switch). Savings & incentives: • Federal ENERGY STAR tax credit (Section 25C): up to $300 for qualified gas models. • KUB and LCUB often offer $150–$250 rebates for high-efficiency gas equipment. • We provide 0 % financing for 12 months or low-interest options up to 60 months to spread out the cost.
