What Sebastian Does to a Tankless Heater
Plenty of Sebastian tankless heaters replaced worn-out tank units. Problems usually start with scale building in the exchanger or with worn valves and fittings.
Local factors in Sebastian
- Mineral-heavy water. On water like this, a heater that has gone its whole life without descaling tends to overheat internally while the faucet stays lukewarm. Flushing it is often half the repair.
- Garage-mounted heaters. A garage wall is the usual spot for heaters here, which keeps them sheltered from weather and simple to service.

If you need tankless water heater repair in Sebastian, FL, your problem is very likely listed here. Each symptom has only a handful of possible causes.
Clicks, but no flame
A no-ignition code points to low gas pressure, a sooted flame rod, a tired igniter or a vent obstruction, and we test each.
Puddle below the heater
Where the water comes from decides the bill: a valve or a joint is minor, a failed exchanger is not.
Air supply or exhaust fault
The burner shuts down on an air or exhaust fault to keep you safe. We clear and inspect both intake and exhaust.
Cuts out partway through a shower
Flow has fallen under the firing minimum, usually from a plugged screen, aerator or shower valve cartridge, or a sensor reading low.
Water isn't as hot anymore
Mineral scale in the exchanger, a gas supply that sags, or a temperature sensor giving a false reading.
Rinnai showing LC
That's the scale warning. The exchanger is due for a descale, and it shouldn't wait long.

Keep It Running or Replace It in Sebastian?
A gas tankless heater that gets regular flushes often keeps going for two decades or more, so one bad part almost never justifies a new unit. Once a heater is past 15 years and its exchanger fails without warranty coverage, replacement starts to make more sense.
Grab the model and serial numbers from the rating plate and ring (888) 987-0567. Age plus symptoms is usually enough to settle the repair question over the phone.
