FAQs

What are the main advantages of installing a tankless water heater in my Andersonville home?

Tankless (on-demand) water heaters heat water only when you open a tap, eliminating standby losses from a storage tank. That means endless hot water, energy savings of 20-40 %, a unit that hangs on the wall to free up floor space, and an expected service life of 20+ years—about double that of a conventional tank heater. Many Andersonville homeowners also appreciate the built-in scale detection features that protect the system from Chicago’s moderately hard water.

How does a tankless system provide "endless" hot water?

Inside the unit, high-output gas burners or electric heating elements activate the moment flow is detected. Cold water travels through a heat exchanger and exits at the temperature you set—continuously—as long as gas (or electricity) and water keep flowing. Because there’s no storage tank to drain, you don’t "run out" of hot water during back-to-back showers or laundry cycles.

Is a tankless water heater compatible with the older plumbing found in many Andersonville houses?

Yes. Our technicians evaluate your existing gas line, venting path, water pressure, and electrical service during a free on-site survey. In many cases we can reuse existing ½-inch gas piping and vent through the same chimney or an exterior wall. For homes with outdated galvanized supply lines or undersized gas service, we’ll quote any required upgrades so you know the full cost up front. All work is done to Chicago and Illinois plumbing codes and the City of Chicago permit requirements.

What size tankless water heater do I need?

Sizing depends on simultaneous demand, not tank volume. We calculate your home’s peak flow rate (e.g., shower + dishwasher + sink = 4.0 gpm) and select a unit that can raise incoming winter water (about 45 °F in Andersonville) to 120 °F at that flow. Most two-bathroom homes need a 7–9 gpm gas model; larger or multi-family buildings may require cascading two units. We’ll present options and performance charts so you can choose the best fit.

How long does installation take and what should I expect?

A standard replacement—removing the old tank, mounting the new unit, upgrading the vent, and reconnecting water/gas—takes about one full workday. We protect floors, haul away the old heater, and commission the new system by flushing, checking gas pressure, and setting temperature. If additional gas piping or electrical circuits are required, installation may extend to a second day. You’ll receive a walkthrough, maintenance tips, and warranty paperwork before we leave.

What does a tankless installation cost and will I really save money?

Installed price in Andersonville typically ranges from $3,200 to $4,800 for a high-efficiency gas unit, depending on capacity and venting complexity. Operating costs are 15-40 % lower because you’re not reheating stored water, and ENERGY STAR® models often qualify for $100–$300 in utility or federal tax rebates. Most households see payback in 5–7 years, and the longer service life means fewer replacements over time. We’ll provide a detailed cost-of-ownership comparison during your estimate.
