Tankless Water Heater Repair in Daniel Island, SC

Common Tankless Water Heater Problems We Fix

Identifying the specific issue with your tankless water heater is the first step toward an effective repair. Our skilled technicians are familiar with the common symptoms and underlying causes of tankless malfunctions.

1. No Hot Water or Intermittent Hot Water: This is perhaps the most frustrating issue. It can stem from various sources, including ignition failures (pilot light or electronic ignition problems), issues with the gas supply, a faulty flow sensor that isn't detecting water movement, or even mineral buildup restricting water flow. We meticulously troubleshoot these components to pinpoint the exact cause and restore consistent hot water.
2. Error Codes Displayed: Modern tankless water heaters often feature diagnostic error codes that appear on the unit's display. These codes are invaluable in guiding our technicians directly to the problem area. Common codes might indicate anything from ignition failure (e.g., E01) to excessive temperature (e.g., E10) or flow sensor malfunctions. Our team understands these codes across various brands, allowing for precise and efficient diagnostics.
3. Fluctuating Water Temperature: If your hot water isn't consistently hot or cycles between hot and cold, it could be due to mineral buildup within the heat exchanger. This buildup can impede efficient heat transfer, leading to temperature inconsistencies. Improper sizing for your home's demand or low water flow can also contribute to this problem.
4. Low Water Pressure: Sediment buildup within the unit or blockages in the ventilation system can restrict water flow, leading to noticeable drops in water pressure. A failing or clogged water filter can also be a culprit. We inspect all relevant pathways to identify and clear obstructions.
5. Leaking Tankless Water Heater: While less common than with traditional tanks, leaks can occur. These often indicate loose connections, a failing pressure relief valve, or, in more severe cases, a crack in the heat exchanger. Any sign of a leak requires immediate professional attention to prevent water damage and further system degradation.
6. Strange Noises: Banging, hissing, popping, or whistling sounds coming from your tankless unit are usually indicators of internal issues. Calcification (mineral scaling) is a common cause, as sediment heats up and expands, creating noise. Loose components or issues with the burner can also produce unusual sounds, signaling a need for inspection.

When to Repair vs. Replace Your Tankless Water Heater

Deciding whether to repair or replace your tankless water heater can be a complex decision. We provide honest assessments based on several factors:

1. Age of the Unit: While tankless heaters typically last 20 years or more, older units may experience more frequent breakdowns.
2. Frequency of Repairs: If your unit requires constant repairs, the cumulative cost might approach that of a new installation.
3. Cost of Repair vs. New Installation: We provide transparent estimates for repairs. If the repair cost is a significant percentage of a new unit's price, replacement might be a more economical long-term solution. You can also explore financing options for new installations.
4. Energy Efficiency: Newer models often boast superior energy efficiency, potentially leading to significant long-term savings on utility bills.

Our technicians will guide you through this decision, offering insights into both options so you can make an informed choice that best suits your needs and budget.
