FAQs
What are the main advantages of installing a tankless water heater in my Winfield home?
Tankless (on-demand) water heaters heat water only when you open a tap, eliminating standby heat loss from a storage tank. In Winfield’s climate this can translate to energy savings of 20–40 %, lower utility bills, a virtually endless supply of hot water, and space-saving wall mounting. Most units also last 18–20 years—about twice as long as a traditional tank—giving you a better long-term return on investment.
How do I determine the correct size (flow rate and BTU) for a tankless unit?
Sizing is based on the peak gallons per minute (GPM) you’ll need and the temperature rise between incoming cold water and your desired hot-water setpoint. Our licensed plumbers first add up the flow rates of fixtures that may run simultaneously (e.g., shower = 2.0 GPM, kitchen faucet = 1.5 GPM, etc.). In Winfield, incoming water is typically 50–55 °F, so to reach 120 °F you need a 65–70 °F rise. We match that load with a unit capable of delivering the required GPM at that temperature rise—often 160–199 kBTU for an average 2- to 3-bath home. We handle all calculations during a free in-home assessment to ensure you never run out of hot water.
Do I need a permit to install a tankless water heater in Winfield, and will your team handle it?
Yes. DuPage County and the City of Winfield both require plumbing and, when applicable, mechanical permits for replacing a water heater—tank or tankless. As licensed, bonded, and insured plumbers, we pull all necessary permits, schedule any required inspections, and ensure the installation meets Illinois Plumbing Code, manufacturer specifications, and local venting/gas line standards. You won’t have to navigate the paperwork or inspector coordination yourself.
How long does a professional tankless water heater installation take?
Most straightforward replacements take 4–6 hours. This includes draining and removing your old tank, mounting the new unit, upgrading gas lines to the larger ¾-inch (or CSST) diameter often required, running Category III/IV venting through an exterior wall or roof, connecting water lines, installing a condensate neutralizer, and testing for leaks. If we have to relocate the heater, upgrade electrical circuits, or bring venting up through multiple floors, installation can extend to a full day. You will have hot water again before we leave.
What kind of maintenance does a tankless water heater require after installation?
Unlike storage tanks, tankless units need periodic descaling to remove mineral buildup on the heat exchanger—especially with Winfield’s moderately hard water (≈ 11 grains per gallon). We recommend an annual service that involves flushing the system with food-grade vinegar, cleaning the inlet screen, testing gas pressure, and verifying combustion settings. The process takes about an hour and greatly extends system life and efficiency. We offer affordable maintenance plans that include priority scheduling and discounted parts.
How much does a licensed tankless water heater installation cost in Winfield?
Prices vary with unit capacity, fuel type, venting route, and any gas or electrical upgrades required. For most Winfield homes, a fully installed natural-gas tankless system ranges from $3,200 to $4,800, which includes the heater, vent kit, isolation valves, permit fees, labor, and haul-away of the old tank. High-output or recirculating models can cost $5,000–$6,000. We provide firm, upfront quotes after an on-site evaluation and offer financing options and manufacturer rebates that can reduce your out-of-pocket cost.
