Tankless Units in Marion Homes

Most Marion homes keep the tankless in the basement, beside the furnace. Hard water and cold winters are what wear these units down.

What we run into in Marion

  • 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.
  • Freeze damage. A hard freeze can split the pipes feeding a unit. Its built-in freeze protection only works while the unit still has power and gas.
  • 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.

What you get

How a Repair Visit Runs in Marion

Every visit follows the same order, so the part that gets replaced is the part that actually failed.

  1. 01

    Error history read

    The code on the display and the unit's stored fault history are read before a single cover comes off.

  2. 02

    Gas pressure under load

  3. 03

    Flow and inlet filter

    The inlet filter screen is cleaned and the flow rate checked. Too little flow and a unit will not fire at all.

  4. 04

    Ignition and flame

  5. 05

    Venting and condensate

    Intake and exhaust terminations are checked for blockage, and the condensate line for clogs and corrosion.

  6. 06

    Sensors and board

  7. 07

    Fixed, then run hard

Common faults

Tankless Problems We Fix Around Marion

The list below covers what we find on most visits for tankless water heater repair in Marion, IN, from ignition codes to drips under the cabinet.

Flame rod cleaned above the burner during tankless water heater repair in Marion, IN

Code 11, E003 or 111

A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.

Drip at the service valves under the unit, traced during tankless water heater repair in Marion, IN

Drip from the cabinet

Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Intake and exhaust terminations cleared during tankless water heater repair in Marion, IN

Code 10 or E110

Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.

Not as hot as it used to be

Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.

Cold at one tap only

Usually a mixing valve or a cold-water crossover at that fixture, not the heater.

Display is blank

No power at the outlet, a blown fuse or a failed control board.

Repair or replace

Fix It or Retire It? Deciding in Marion

Gas tankless units commonly last 20 years or more with flushing, so a single failed part rarely means a new heater. A failed exchanger outside its warranty, on a unit past 15 years, is where replacement starts to win.

Read the model and serial off the label and call (380) 273-8196. The age and the fault together usually settle repair versus replace on the phone.

Why Marion Homeowners Call Us

Scale treated, not ignored

If scale caused the fault, the exchanger is descaled as well, so the same code doesn't return next month.

Quote in writing

The cause and the price are written down before work starts, whether the job is a filter or an exchanger.

The code is a starting point

Error codes name a system, not a part. Gas, flow, venting and sensors are measured before anything is replaced.

How much does tankless water heater repair in Marion, IN 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.

Can a tankless water heater be repaired?

Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.

Why does my tankless water heater go hot then cold?

A second or two of cold after the tap reopens is normal start-up. If the water swings while it runs, look at low flow, scale or the flow sensor.

Is there a reset button on a tankless water heater?

Many do it through power: switch the unit off, wait, switch it back on. That clears a code, but a code that comes back means a part needs attention.
