FAQs
How does a tankless water heater work, and is it a good choice for homes in Clinton?
Unlike traditional units that keep 40–80 gallons of water hot all day, a tankless water heater heats water only when you open a tap. Cold water flows across a powerful gas burner or electric element, delivering a continuous supply of hot water within seconds. For homes in Clinton—where energy costs continue to rise—going tankless can cut water-heating expenses by 25–40 % and eliminates the risk of a catastrophic tank leak.
What size (flow rate) tankless unit do I need for my household?
Sizing is based on "gallons per minute" (GPM) you expect to use simultaneously and on the temperature rise needed in Clinton’s climate. For example, if two showers (2.0 GPM each) and a washing machine (2.5 GPM) might run together, you’ll need at least a 6.5 GPM unit. Because Clinton’s incoming water temperature averages about 55 °F, we typically choose units capable of delivering a 60 °F rise at that flow rate—usually a 180,000 BTU gas model or a 27-kW electric model.
Can a tankless water heater be installed in the same place as my old tank unit?
Often yes, but there are a few extra considerations. Tankless units are smaller and wall-mounted, so they free floor space. However, they require a larger gas line (¾ in. or more) or higher-amperage electric wiring, sealed combustion venting, and an accessible condensate drain. Our licensed plumbers will inspect your existing utility hookups, verify compliance with Clinton city code, pull any necessary permits, and give you a fixed-price quote before work begins.
How much maintenance does a tankless water heater need?
Minimal but important. Because the Mississippi River valley has moderately hard water, annual descaling is recommended to prevent mineral buildup on the heat exchanger. The process takes about an hour: we flush the unit with food-grade vinegar and check the burner, fan, and condensate trap. With routine service, a tankless water heater can last 20+ years—roughly twice the lifespan of a storage tank.
Will a tankless heater still work during Clinton’s winter cold snaps?
Yes, modern units include built-in freeze protection down to about ‑22 °F as long as they remain powered. We also insulate the water lines within three feet of the heater and install an automatic drain-down valve for added security. If you lose power during extreme cold, simply turn off the unit and open the hot-side faucet to relieve pressure and prevent freezing.
What rebates or incentives are available for installing a tankless system in Clinton?
Depending on fuel type, you may qualify for a federal tax credit of 30 % of the project cost (up to $600 for gas and $2,000 for qualifying high-efficiency heat-pump water heaters). Atmos Energy and Entergy Mississippi often offer $250–$400 utility rebates for ENERGY STAR-certified gas units. We handle all paperwork and provide the AHRI certificate and invoice you’ll need to claim local and federal incentives.
