Tankless Units in Willis Homes
Most Willis 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 Willis
- 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 Willis, TX, it is nearly always one of these problems. Each has a short list of causes.
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.
Display is blank
No power at the outlet, a blown fuse or a failed control board.
Frozen after a cold night
Lines feeding the unit froze, or freeze protection lost power.
Error code keeps coming back
A reset only clears the symptom. Repeated ignition or exhaust codes need a visit.

Willis Homes by the Numbers
Electricity heats about 84% of homes in Willis, 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 1990, homes in Willis sit in the middle: plenty were retrofitted with tankless units, and plenty of those units are now old enough to need parts. Willis is about evenly split between owners (around 55%) and renters, so calls come from homeowners and from landlords and property managers alike.
Willis covers about 4.7 square miles and holds roughly 6,693 residents, around 1,415 per square mile: spread out, with mostly detached homes on larger lots and longer runs between fixtures and the street. It is number 156 by population of the 322 Texas places on our service list.

Willis Weather and Water Temperature
Willis averages around 16 freezing nights a year, with a three-year low of about 8°F. That is enough cold for pipes in garages, crawl spaces and outside walls to get close to trouble on the worst nights, while most winters pass without damage.
Water arriving at a Willis tap in winter is likely near 60°F (averages of about 50°F in January air and 69°F over the year). To reach 120°F a tankless unit must add roughly 60°F, which a 199,000 BTU gas model at 90% efficiency can do for about 6.0 gallons per minute. In July the water is nearer 78°F, so the same unit has to add only about 42°F and can supply about 8.5 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.

Tankless Water Heater Repair in Willis, TX: FAQs
Question not covered here?

Call (380) 273-8196How much does tankless water heater repair in Willis, 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.
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 Willis, with winter tap water near 60°F, a gas unit can hold 120°F for about 6.0 gallons per minute, and opening a second tap past that point is a common cause of the swing.
