Tankless Units in Aynor Homes
In Aynor, 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 Aynor
- 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.
- Retrofit installs. Retrofits are common in this housing stock. When a unit throws flame codes only while the furnace or dryer runs, the gas supply is the first suspect.

The list below covers what we find on most visits for tankless water heater repair in Aynor, SC, from ignition codes to drips under the cabinet.
Unit won't light
A unit that clicks without lighting has an ignition, gas or venting fault, and each is checked in turn.
Drip from the cabinet
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.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Noisy or whistling
Scale, a struggling fan or a gas regulator issue, each of which shows up on testing.
Hot, then cold, then hot
A short cold burst after the tap reopens is normal start-up. Swings during one shower point to low flow, scale or a failing flow sensor.

Aynor Homes by the Numbers
Electricity heats about 97% of homes in Aynor, 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 1990, 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. About 70% of homes are owner-occupied and about 83% are single-family, so most repair decisions here are the homeowner's own.
With about 1,077 residents on roughly 1.8 square miles (near 598 per square mile), Aynor is rural to small-town in density, with large lots and long runs. Among the 188 South Carolina places we cover, it ranks number 110 by population.

Aynor Weather and Water Temperature
Aynor averages around 25 freezing nights a year, with a three-year low of about 17°F. That is enough cold for pipes in garages, crawl spaces and outside walls to get close to trouble on the worst nights, while most winters pass without damage.
Water arriving at a Aynor tap in winter is likely near 55°F (averages of about 46°F in January air and 65°F over the year). To reach 120°F a tankless unit must add roughly 65°F, which a 199,000 BTU gas model at 90% efficiency can do for about 5.5 gallons per minute. In July the water is nearer 73°F, so the same unit has to add only about 47°F and can supply about 7.7 gallons per minute.
Since a shower uses about 2 gallons per minute, that winter ceiling is why a heater that handles one shower easily can run lukewarm when a second shower and the dishwasher start. Lukewarm water at full demand is a limit of the design, not always a fault, whereas lukewarm water at a single tap points to scale, a sensor or an ignition problem.

Call (380) 273-8196How much does tankless water heater repair in Aynor, 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.
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. In Aynor, scale and demand overload are more likely culprits than frost damage.
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.
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. Around Aynor the winter supply is likely near 55°F, which limits a typical gas unit to roughly 5.5 gallons per minute at 120°F, so a swing that only happens with several taps open is usually that limit.
