FAQs
What advantages does a tankless water heater offer over a traditional storage-tank heater for Andersonville homes?
Tankless (on-demand) systems heat water only when you open a tap, so they eliminate standby heat loss from a 40–50 gal tank. This typically cuts water-heating costs by 20-40 %, frees up several square feet of floor space, and provides an endless supply of hot water—ideal for busy Andersonville households with back-to-back showers or laundry loads. Tankless units also last 18–20 years on average, roughly twice as long as a tank heater, and many qualify for federal or Illinois energy-efficiency rebates.
How long does a professional tankless water heater installation usually take in Andersonville?
Most straight-forward replacements are finished in one workday (about 4–8 hours). This includes removing the old tank, mounting the new unit, making gas or electric connections, installing venting, and performing startup tests. If upgrades are needed—such as upsizing a gas line, adding a condensate drain, or relocating the heater—installation may extend to a second day. We provide a precise timeline after an on-site evaluation.
What size or capacity tankless unit do I need for my household?
Sizing is based on peak hot-water demand, measured in gallons per minute (GPM). We look at how many fixtures might run simultaneously (e.g., two showers and a dishwasher). A typical Andersonville family of four requires 6–8 GPM for gas units or 7–9 kW per point of use for electric models. During our free estimate we calculate your exact demand, local groundwater temperature, and fuel type to recommend the right model so you never run out of hot water.
Will a tankless water heater really lower my energy bills?
Yes. Because the burner or heating elements fire only when water is needed, tankless units avoid the constant reheating a storage tank performs throughout the day. Andersonville residents switching from an older gas tank can save $75–$120 per year; electric tank users often see even higher savings. High-efficiency (condensing) gas models with a 0.95+ UEF can boost savings further and may qualify for a 30 % federal tax credit (up to $600) under the Inflation Reduction Act.
What maintenance does a tankless system require and how often?
Annual maintenance keeps your warranty valid and ensures top efficiency. We flush the heat exchanger with a vinegar or descaling solution to remove mineral buildup, inspect the burner or elements, clean the inlet filter, and verify venting and combustion settings. With Chicago’s moderately hard water, we recommend flushing once per year; homes with water softeners may extend this to every 18–24 months. Maintenance visits take about an hour and cost far less than a premature heat-exchanger replacement.
Will my home need gas, vent, or electrical upgrades before installation?
Possibly. High-output gas tankless units often require a ¾-inch gas line and a Category III/IV stainless or PVC vent. If your Andersonville home currently has a ½-inch gas line to the water heater or uses B-vent, we’ll quote an upgrade. Electric tankless models draw 60–120 amps at 240 V, which can necessitate additional breakers or even a service-panel upgrade. During our in-home assessment we inspect fuel lines, panel capacity, vent routes, and drain locations so you know all costs upfront—no surprises on install day.
