Price
What Sets the Price of a Tankless Water Heater Repair

Code and Failed Part
An igniter, a flame sensor, and a gas valve differ in price.
Scale in the Heat Exchanger
Local water at about 10.8 grains per gallon can add a flush.
Vent or Gas Supply Fixes
A blocked vent or a short gas supply adds labor.
Warranty Coverage

Codes and Permits That Apply in Draper
Draper's earthquake handout and CPSC guidance both apply to a tankless unit in your home.
- Draper City's earthquake handout calls for flexible gas and water connections to appliances, so the plumber checks them.

- Draper ties plumbing permit work to a Utah licensed plumbing contractor or a residential Owner-Builder.
Warranty, insurance, rebates
Coverage and Rebate Questions
The Utah Insurance Department places broken water heater damage outside flood coverage and points to the home policy. The Insurance Information Institute's sample HO-3 form excludes the unit itself; see water heater questions.
ThermWise from Enbridge Gas Utah lists current water heater rebates, and the IRS 25C credit ended after 2025.
A heat exchanger check before a warranty claim shows what it can cover, and we suggest keeping the warranty paperwork near the unit.
Does Draper's Hard Water Harm a Tankless Water Heater?
Yes, minerals leave scale in a tankless unit, and the VC manual calls for treatment or flushing. WaterPro reports average hardness of 184.1 mg/L, a figure we took from its 2025 report. Ask about a flushing schedule for your address when you call.
Is Tankless Scale Damage Covered by the Warranty?
No, the VC manual excludes scale damage, even though the heat exchanger carries a 12 year warranty and labor carries 1 year. The plumber records the scale level before any claim, so you know what the maker can cover. Bring the warranty paperwork to the call.
Local factors
Draper Details That Change the Repair
WaterPro serves part of Draper from 4 deep wells and 8 streams, and Draper City water comes 100% from JVWCD. We name both systems because the water bill shows which one serves your address.
DOE gives tankless units more than 20 years, so a repair gets weighed against Tankless Water Heater Installation of a new unit.
Questions
Questions Before You Call
Tap any question to read the answer below it
What Flushing Schedule Fits a Tankless Unit on Draper Water
The interval follows the scale found in your heat exchanger, since the VC manual says mineral-heavy water needs treatment or flushing.
Can a Tankless Unit Showing Code 12 Be Repaired
Yes, code 12 is a repair call. The VC manual lists it as flame failure. The plumber checks the gas supply, flame sensing, and vent before pricing parts.
Why Does My Tankless Water Heater Shut Off at Low Flow
The VC manual says the burner needs a minimum flow rate to start, so a trickle leaves it unlit. The plumber checks the fixture flow and the inlet screen.
Is a Tankless Unit Worth Repairing After 15 Years
A sound unit can be, since DOE says tankless units can last more than 20 years. A heat exchanger check for scale damage comes before that choice.
