Tankless Units in Andrews Homes
Andrews winters are mild but not frost-free, and an outdoor unit without power on a freezing night can crack a fitting. Flow sensors and igniters are the other usual parts.
What we run into in Andrews
- 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 Andrews, SC. The display usually points at one of them.
Code 11, E003 or 111
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
Venting codes mean the unit can't breathe: a blocked termination, a nest, snow or a vent run that's too long.
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.
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.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.

Andrews Homes by the Numbers
Electricity heats about 84% of homes in Andrews, so electric tankless units, with their heavy-amp circuits and element faults, are as common here as gas ones. With a median build year of 1981, homes in Andrews sit in the middle: plenty were retrofitted with tankless units, and plenty of those units are now old enough to need parts. Andrews is about evenly split between owners (around 57%) and renters, so calls come from homeowners and from landlords and property managers alike.
Andrews covers about 2.2 square miles and holds roughly 2,558 residents, around 1,157 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 78 by population.

Andrews Weather and Water Temperature
Hard freezes are rare in Andrews, roughly 8 nights a year, but the coldest night of the past three years still dipped to about 20°F. One cold snap can catch outdoor units and uninsulated lines that were never built for it.
In Andrews the cold tap is probably around 58°F in winter and 74°F in summer, based on a January average of 49°F, a July average of 82°F and a yearly average of 66°F. Heating that water to 120°F takes a rise of about 62°F in winter, so a 199,000 BTU gas unit at 90% efficiency tops out near 5.7 gallons per minute, compared with roughly 7.8 in summer when the rise is only about 46°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.

Call (380) 273-8196How much does tankless water heater repair in Andrews, 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 is my tankless water heater not turning on?
Check for power at the outlet and that the gas valve is open. Beyond that it is usually low flow, a clogged inlet filter, a failed flow sensor or an ignition fault. In Andrews, if the unit is outdoors, also check that nothing is blocking the vent cap, since insects and debris are the usual blockages in mild climates.
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 Andrews freezing nights are few (about 8 a year), so any season works; choose a month when the household can go without hot water for an hour.
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.
