Tankless Units in Florence Homes
In Florence, units are often retrofits on older homes. Ignition faults and frozen lines after a cold snap are the common repairs.
What we run into in Florence
- Freeze damage. Cold snaps do damage here when the power drops overnight. A frozen line or a cracked fitting under the unit is a repair we see after every deep freeze.
- Retrofit installs. In older homes converted to tankless, the original gas piping is not always big enough. Pressure gets measured with the burner at full fire before parts are blamed.

These are the faults behind most calls for tankless water heater repair in Florence, SC. The display usually points at one of them.
Unit won't light
No ignition usually means gas pressure, a worn igniter, a dirty flame rod or a blocked vent. Each is tested.
Water under the unit
Water below a tankless can be a valve, a fitting, condensate or a failed exchanger. The source decides the cost.
Venting fault
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
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.

Fix It or Retire It? Deciding in Florence
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.
Tell us the brand, roughly how old the unit is and what it is doing when you call (380) 273-8196. If a repair is a poor spend, you will be told so.

Florence Homes by the Numbers
Electricity heats about 79% of homes in Florence, so electric tankless units, with their heavy-amp circuits and element faults, are as common here as gas ones. The median home here dates from 1982, so tankless units are a mix of original-era installs and newer replacements, and an older unit that has never been descaled is a frequent find. Roughly 60% of homes are owner-occupied and 70% single-family, so calls come from both homeowners and landlords.
Florence covers about 25 square miles and holds roughly 40,205 residents, around 1,620 per square mile: spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. Among the 188 South Carolina places we cover, it ranks number 10 by population.

Call (380) 273-8196How much does tankless water heater repair in Florence, SC 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. Freeze repairs depend on what split, and are priced once the damage is seen.
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.
What is the most common problem with tankless water heaters?
Scale in the heat exchanger, followed by ignition faults and flow sensor or filter problems. All three usually show up as a code or as water that won't stay hot.
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.
