Tankless Units in West Union Homes
Many West Union homes are brick ranches where the tankless went onto an outside wall or into the garage. Occasional hard freezes and gas supply sizing cause most of our calls.
What we run into in West Union
- Freeze damage. Freeze protection keeps the inside of a unit safe, not the exposed pipes under it. Uninsulated lines are where winter damage usually starts.
- Retrofit installs. Plenty of units here were fitted into older homes after the fact, and an undersized gas line or a long vent run can cause ignition faults years later.

Call (380) 273-8196Tankless Problems We Fix Around West Union
The list below covers what we find on most visits for tankless water heater repair in West Union, SC, from ignition codes to drips under the cabinet.
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.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
LC code on a Rinnai
The unit is reporting scale buildup. It needs a descale, and soon.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.

Fix It or Retire It? Deciding in West Union
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.

West Union Homes by the Numbers
With electricity the main heating fuel in West Union (about 76% of homes), many tankless units here are electric, and their faults are elements, breakers and sensors rather than burners. The median home here dates from 1984, 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. Owners live in about 76% of West Union homes (single-family about 68%), so the person who calls is usually the person who decides.
West Union covers about 0.8 square miles and holds roughly 396 residents, around 501 per square mile: rural to small-town in density, with large lots and long runs. Among the 188 South Carolina places we cover, it ranks number 155 by population.

West Union Weather and Water Temperature
West Union sees about 70 nights a year at or below freezing, and the coldest night of the last three winters fell to 7°F. Where that is normal, exposed water lines, condensate drains and outdoor vent terminations are the parts that fail first, and a heater with no freeze protection or a power cut is a real risk.
In West Union the cold tap is probably around 52°F in winter and 71°F in summer, based on a January average of 43°F, a July average of 80°F and a yearly average of 61°F. Heating that water to 120°F takes a rise of about 68°F in winter, so a 199,000 BTU gas unit at 90% efficiency tops out near 5.3 gallons per minute, compared with roughly 7.3 in summer when the rise is only about 49°F.
For comparison, a shower draws roughly 2 gallons per minute, so two at once plus the dishwasher can pass the winter figure. If the water goes lukewarm only when several taps run, the unit is likely maxed out; if it goes lukewarm at one tap, the cause is more often scale, a flow sensor or the flame.
West Union sits near 963 ft, well under the 2,000 ft level at which gas appliances commonly need altitude adjustments, so burner output should not be a concern from elevation alone.

Call (380) 273-8196How much does tankless water heater repair in West Union, 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.
How long does a tankless water heater last?
A gas unit that is flushed regularly commonly lasts 20 years or longer. Electric tankless models usually give 7 to 10. In West Union the heat exchanger works through a rise of about 68°F on a typical winter day, which is why flushing on schedule matters there.
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 West Union, cold nights add vent-cap, condensate-line and exposed-pipe problems to the usual list.
How often should a tankless water heater be flushed?
Most makers call for a flush every year, and every six months on very hard water. On very soft water the gap can be longer, but skipping it for years invites scale faults. In West Union, do the flush in autumn, before the freezing nights (about 70 a year) begin, so nobody is working the service valves in a frozen garage.
