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

Mount Olive Homes by the Numbers
With electricity the main heating fuel in Mount Olive (about 73% of homes), many tankless units here are electric, and their faults are elements, breakers and sensors rather than burners. With a median build year of 1962, many homes in Mount Olive were set up for a tank heater, which means a tankless unit often depends on a retrofitted gas line, vent run or drain. Roughly 53% of homes are owner-occupied and 72% single-family, so calls come from both homeowners and landlords.
Mount Olive covers about 2.7 square miles and holds roughly 4,204 residents, around 1,534 per square mile: spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. Among the 301 North Carolina places we cover, it ranks number 121 by population.

Mount Olive Weather and Water Temperature
Freezing nights are not constant in Mount Olive, about 40 a year, but the coldest one in the last three years reached about 15°F. A unit mounted outdoors or in an unheated garage is exposed on those nights, and a leak found in spring often started in January.
In Mount Olive the cold tap is probably around 53°F in winter and 72°F in summer, based on a January average of 43°F, a July average of 81°F and a yearly average of 63°F. Heating that water to 120°F takes a rise of about 67°F in winter, so a 199,000 BTU gas unit at 90% efficiency tops out near 5.3 gallons per minute, compared with roughly 7.4 in summer when the rise is only about 48°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.

Tankless Water Heater Repair in Mount Olive, NC: FAQs
Question not covered here?

Call (380) 273-8196How much does tankless water heater repair in Mount Olive, NC 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?
Gas units commonly run 20 years or more when they are flushed on schedule. Electric tankless units tend to last closer to 7 to 10 years. In Mount Olive the heat exchanger works through a rise of about 67°F on a typical winter day, which is why flushing on schedule matters there.
How often should a tankless water heater be flushed?
Once a year for most homes, and twice a year on very hard water. Soft-water homes can stretch it, but never skip it for years. In Mount Olive freezing nights are few (about 40 a year), so any season works; choose a month when the household can go without hot water for an hour.
Why is my tankless water heater not turning on?
First confirm power and gas. If both are there, the usual causes are low flow, a dirty inlet filter, a bad flow sensor or an ignition fault. In Mount Olive, after a hard freeze also check whether the condensate line has frozen, since many condensing models shut down when it blocks.
