Tankless Units in Kaufman Homes
Most Kaufman homes are brick houses where the tankless sits in the garage or on an outside wall. The February 2021 freeze showed how fast exposed lines can split here.
What we run into in Kaufman
- 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.

When people phone about tankless water heater repair in Kaufman, TX, it is nearly always one of these problems. Each has a short list of causes.

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
Drips come from service valves, fittings, the relief valve, the condensate line or the heat exchanger itself.

Code 10 or E110
An air or exhaust code stops the burner for safety. The intake and exhaust are cleared and checked.
Not as hot as it used to be
Scale on the heat exchanger, a weak gas supply or a thermistor reading wrong.
Cold at one tap only
Usually a mixing valve or a cold-water crossover at that fixture, not the heater.
Display is blank
No power at the outlet, a blown fuse or a failed control board.

Tankless Water Heater Repair in Kaufman, TX: 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 Kaufman, TX 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 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.
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.
