Common Tankless Problems We Fix
- Error codes / shut-downs: scale-related overheat, flow sensor faults, ignition/combustion issues, vent/air faults
- No hot water / temp swings: clogged inlet screen, faulty flow sensor, gas supply undersized, mixing valve issues
- Leaks: heat-exchanger gaskets, service-valve connections, condensate drain problems
- Noise/short cycling: scale buildup, fan/combustion imbalance
- Safety/code items: improper venting, lack of condensate neutralizer where required, gas line sizing
How We Diagnose (Free Service Call)
We begin with a Free Service Call to evaluate and pull diagnostic history. You’ll get clear findings and written options before any work begins—no pressure. If advanced diagnostics are needed (combustion analysis, gas-supply test, descaling setup), we’ll explain why and review the cost first.
Every repair visit includes:
- Safety check (gas, venting/combustion, electrical)
- Verify model/serial, settings, recirculation mode (if present)
- Check inlet screens/filters and condensate path
- Maintenance plan to prevent repeat faults
Annual Descale & Service (Preventative)
Scale is the primary cause of tankless error codes and temperature instability.
Annual tankless service includes:
- Descale/flush of the heat exchanger with food-grade solution
- Clean inlet screens/filters; verify flow sensor operation
- Inspect condensate trap/drain and venting
- Check fan/combustion, run diagnostics, clear error memory
- Update maintenance reminders and verify recirculation settings
Recommended frequency: annually (semi-annually in hard water/heavy use).
Benefits: stable temperatures, higher efficiency, fewer shutdowns, longer system life.
Typical Lifespan (and How to Extend It)
- Tankless systems: ~15–20 years with routine descaling and filter cleaning
Extend life with: annual descale, clean inlet screens, proper gas line sizing and venting, surge protection where recommended.
Repair vs. Replace — How to Decide
Replace when:
- Heat exchanger is compromised or repairs approach replacement cost
- Unit is well past lifespan with recurring high-cost faults (boards, fans, valves)
- Major venting/gas upgrades required make repair uneconomical
- Capacity consistently fails to meet household demand
Repair when:
- Scale-related faults or single components fail on a younger unit (flow sensor, fan, igniter, valves)
- Maintenance (descale/filters/condensate) resolves temp swings or error codes
