Tankless Units in Combs Homes
Combs water comes from limestone country and is hard, and winters bring real freezes. Units here need descaling and protected lines.
What we run into in Combs
- Hard water. Mineral-heavy water coats the exchanger a little more every month. Many repair visits here end with a descale as well, so the fix holds.
- 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.

Most requests for tankless water heater repair in Combs, KY start with one of the symptoms below, and most end with a single part or a descale.
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.
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.

Combs Weather and Water Temperature
Combs sees about 90 nights a year at or below freezing, and the coldest night of the last three winters fell to 1°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.
Water arriving at a Combs tap in winter is likely near 47°F (averages of about 36°F in January air and 58°F over the year). To reach 120°F a tankless unit must add roughly 73°F, which a 199,000 BTU gas model at 90% efficiency can do for about 4.9 gallons per minute. In July the water is nearer 68°F, so the same unit has to add only about 52°F and can supply about 6.8 gallons per minute.
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.
At about 973 ft above sea level, Combs is below the roughly 2,000 ft mark where manufacturers usually begin to adjust gas appliance ratings, so altitude is not a factor for most tankless units here.

Tankless Water Heater Repair in Combs, KY: FAQs
Question not covered here?
Call and ask. Someone who repairs tankless units answers, and the phone quote is free.
Call (380) 273-8196How much does tankless water heater repair in Combs, KY 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. On hard water, a descale often goes with the repair and sits on the same written quote.
Can a tankless water heater be repaired?
Yes, in most cases. Igniters, flame rods, flow sensors, thermistors, fans, gas valves and boards are all replaceable, and scale can be descaled. A leaking heat exchanger on an old unit is the main exception.
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. In Combs, with winter tap water near 47°F, a gas unit can hold 120°F for about 4.9 gallons per minute, and opening a second tap past that point is a common cause of the swing.
