Tankless Units in Buffalo Grove Homes

In Buffalo Grove, basement units with PVC sidewall vents are typical. Scale from the hard water and snow at the termination are the faults we see most.

What we run into in Buffalo Grove

  • Basement units. In a basement install, a clogged condensate trap or a failed pump can shut the unit down with a code long before anyone sees water.
  • Snow on vents. Snow drifting against a sidewall vent will stop a unit cold with a venting code until the termination is cleared.
  • Hard water. Mineral-heavy water coats the exchanger a little more every month. Many repair visits here end with a descale as well, so the fix holds.

Tankless Problems We Fix Around Buffalo Grove

An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.

Noisy or whistling

Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.

Fix It or Retire It? Deciding in Buffalo Grove

Igniters, flame rods, sensors, fans, gas valves and boards are worth replacing on almost any unit. The hard call is a leaking or cracked heat exchanger on an older unit, because that part can approach the price of new.

How much does tankless water heater repair in Buffalo Grove, IL cost?

Most repairs cost an estimated $150 to $800, depending on the part. Descaling alone is estimated at $150 to $350, and a heat exchanger at $1,000 to $2,500. On hard water, a descale often goes with the repair and sits on the same written quote.

How long does a tankless water heater last?

Gas units commonly run 20 years or more when they are flushed on schedule. Electric tankless units tend to last closer to 7 to 10 years.

Why is my tankless water heater not turning on?

First confirm power and gas. If both are there, the usual causes are low flow, a dirty inlet filter, a bad flow sensor or an ignition fault.

How often should a tankless water heater be flushed?

Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years.
