FAQs
What are the main benefits of choosing a tankless water heater for my Winfield home?
Tankless (on-demand) units heat water only when you open a tap, eliminating standby losses from a storage tank. This typically delivers energy savings of 20–40 %, endless hot water, and a space-saving design that fits on a wall. Modern models also offer longer service life—about 20 years vs. 8–12 years for a tank—plus advanced digital controls and recirculation options to minimize wait times at distant fixtures.
How long does a typical tankless water heater installation take?
For most Winfield homes we complete the job in one business day. A straightforward replacement of a tank unit with an indoor gas-fired tankless model usually takes 6–8 hours, including removal of the old heater, mounting the new unit, upgrading gas line sizing, installing the category III/IV vent, connecting water lines, flushing, and final commissioning. If an electrical circuit or outdoor mounting pad is needed, plan on an extra 1–2 hours.
Does Winfield require any permits or inspections for a new tankless water heater?
Yes. Winfield follows DuPage County / Indiana plumbing and mechanical codes (depending on jurisdiction). A mechanical/plumbing permit must be pulled before work begins. After installation the village inspector will verify proper venting, gas line sizing, condensate drain, seismic strapping (if required), and combustion air clearance. We handle the paperwork, schedule the inspection, and supply the specification sheets the inspector will want to see.
What size tankless unit do I need?
Sizing is based on peak gallons-per-minute (GPM) demand and required temperature rise. We tally simultaneous fixtures—e.g., one shower (2.0 GPM) + dishwasher (1.5 GPM) = 3.5 GPM. Groundwater in Winfield averages 50 °F, so to reach a 120 °F set point you need a 70 °F rise. At that rise you’d choose a 150–180 k BTU, 4–5 GPM unit. Larger homes with spa tubs or multiple showers may require an 11 GPM, 199 k BTU model or even two units in parallel. Our technician will perform the load calculation during the estimate.
How much does a tankless water heater installation cost in Winfield?
Costs vary with capacity, fuel type, venting route, and any code upgrades. As a guide, a high-efficiency condensing gas tankless unit (up to 11 GPM) fully installed runs $3,300–$4,800. Electric tankless models start around $1,500 but often need a 150–200 amp service upgrade, which can add $1,200–$2,000. We provide a written, line-item quote before work begins and can discuss rebates from Nicor Gas or local utilities that currently offer up to $350 back on qualifying ENERGY STAR® models.
What maintenance does a tankless water heater need after installation?
Tankless units require an annual or bi-annual flush with white vinegar or a citric solution to remove mineral scale from the heat exchanger—especially important with Winfield’s 12–16 grains-per-gallon hard water. We install isolation valves so the flush takes about 45 minutes. Also inspect the condensate neutralizer media yearly and replace every 2–3 years. Clearing the combustion air screen and updating firmware via the app (if Wi-Fi equipped) help maintain peak efficiency and protect your warranty.
