Tankless Units in Sebastian Homes

Many Sebastian units went in to replace a tired tank heater. The fittings, the valves and the scale inside the exchanger are where problems start.

What we run into in Sebastian

  • Hard water. With water this hard, a unit that has never been flushed is usually running hot inside and cold at the tap. Descaling is often half of the cure.
  • Garage installs. Many units here are mounted on a garage wall, which keeps them reachable for service and out of the worst weather.

Common faults

Tankless Problems We Fix Around Sebastian

When people phone about tankless water heater repair in Sebastian, FL, it is nearly always one of these problems. Each has a short list of causes.

Flame rod cleaned above the burner during tankless water heater repair in Sebastian, FL

Unit won't light

No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.

Drip at the service valves under the unit, traced during tankless water heater repair in Sebastian, FL

Water under the unit

Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.

Intake and exhaust terminations cleared during tankless water heater repair in Sebastian, FL

Venting fault

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

Shuts off mid-shower

Flow drops below what the unit needs to keep firing: a clogged filter, aerator or shower cartridge, or a sensor misreading.

Not as hot as it used to be

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

LC code on a Rinnai

The unit is reporting scale buildup. It needs a descale, and soon.

Repair or replace

Fix It or Retire It? Deciding in Sebastian

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 Sebastian Homeowners Call Us

Run hard before we go

The unit is pushed with several taps open and its outlet temperature watched before the visit ends.

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.

Scale treated, not ignored

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

How much does tankless water heater repair in Sebastian, FL 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.

Why does my tankless water heater go hot then cold?

A brief cold slug after a tap reopens is the unit restarting. Swings during one shower usually mean flow below the unit's minimum, scale on the exchanger, or a failing flow sensor.
