FAQs
Why should I choose a tankless water heater for my Benton home?
Tankless units heat water on-demand, so you never run out of hot water and you eliminate standby heat loss from a storage tank. In Benton’s moderate climate, a properly sized unit can deliver 2–5 gallons of hot water per minute while lowering energy use by up to 40 % compared with standard tanks. They also last 18–20 years—almost twice as long as a conventional heater—so you save on replacement costs.
How do I know what size (GPM) tankless water heater I need?
Sizing is based on the total gallons per minute (GPM) of hot water your fixtures may demand simultaneously and the temperature rise required in Benton (groundwater averages 60 °F). We calculate the GPM for each fixture (e.g., shower 2.5 GPM, kitchen sink 1.5 GPM) and add them up. Then we determine the temperature rise—typically 60 °F to reach 120 °F hot-water setpoint. For example, two showers running together (5 GPM) need a unit that delivers at least 5 GPM at a 60 °F rise. Our technicians perform this calculation during the in-home evaluation to ensure perfect sizing.
What is involved in converting from a tank to a tankless unit?
A tank-to-tankless conversion usually includes: (1) removing the old tank and disposing of it; (2) installing new wall mounting brackets; (3) upsizing the gas line or adding a dedicated 120 V circuit if it’s an electric unit; (4) running Category III or IV venting directly outside; (5) adding an inline sediment filter to protect against Benton’s moderately hard water; and (6) performing combustion or electrical commissioning tests. Most installations take one day, and we secure all required Benton and Saline County permits.
Will a tankless water heater work with Benton’s water quality?
Yes, but Benton’s water is moderately hard (about 120 ppm). Hardness minerals can scale the heat exchanger, reducing efficiency. We install a pre-filter/scale inhibitor and recommend an annual descaling flush (takes about 45 minutes). Adhering to this simple maintenance routine keeps your warranty intact and your efficiency high.
How much can I expect to save on energy bills?
Actual savings vary with usage, but the U.S. DOE reports gas tankless units save an average household $80–$100 per year; electric units save $40–$60. Larger Benton families that previously kept a 50–80 gallon tank at 120 °F see the biggest reductions because standby losses are eliminated.
Are there rebates or incentives for installing a tankless system in Benton?
Yes. Entergy Arkansas typically offers $300–$400 rebates for qualifying ENERGY STAR® gas tankless models. Electric cooperatives sometimes provide bill credits for high-efficiency upgrades. In addition, the federal Inflation Reduction Act offers a 30 % tax credit (up to $600) on ENERGY STAR® electric or gas tankless water heaters installed in 2023–2032. We supply all paperwork and proof of installation so you can claim every available incentive.
