Proudly helping with Tankless Water Heater Repair in Irving
What are the most common tankless water heater repair types?
A majority of tankless water heater repairs (especially in DFW) involve one of these six key issues:
- Descaling due to mineral buildup
- Ignition system issues (blocked sensors)
- Blockages of vents
- Faulty flow sensors
- Leaks from a damaged heat exchanger or valves
- Damaged gas flexes and closed valves (gas units)
How often should I descale my tankless water heater?
Perform tankless water heater descaling once every 6-12 months in most areas to eliminate mineral buildup in the system.
If you live in areas with extremely hard water- such as Dallas-Fort Worth- consider decaling your on-demand hot water heater every 6-8 months (roughly twice a year). Limescale is particularly hard on tankless units in our area.
How often should I replace the inlet filter on a tankless water heater?
This depends on the water quality in your area and your personal water usage rate. Most homeowners should replace the inlet filter every 6 months.
If your home uses a lot of water, or if you live in regions with extremely hard water (like North Texas), check your inlet filter every 4 months. Increased use and excessive mineral scaling have significant impact on the filter's lifespan.
