Don’t Ignore These Signs Your System Needs Service
Identifying problems early can save you from a complete loss of hot water during the coldest months of the year. While these units are durable, they are complex machines that require specialized knowledge to fix correctly. Look out for these specific indicators that your unit needs a professional tune-up:
- Sudden Temperature Drops: If your water goes cold mid-shower (the “cold water sandwich” effect), there may be a sensor or ignition issue.
- Error Codes on Display: Modern units often provide digital alerts that signal internal component errors or venting obstructions.
- Reduced Water Flow: Significant scale buildup can restrict the passage of water through the narrow copper or stainless steel pipes in the heat exchanger.
- Unusual Rumbling: Grumbling or knocking sounds often point to a need for a professional system flush to remove sediment.
