At St. George Water Heaters, we’ve seen firsthand how convenient and energy-efficient tankless water heaters can be. These systems deliver hot water on demand, which means you never have to worry about running out mid-shower. However, like any major home appliance, tankless water heaters are not immune to issues.
If you’re noticing anything unusual with your system, it may be time to schedule a professional evaluation. Below are the top signs you need tankless water heater repair in St. George to keep your system running at peak performance.
- Inconsistent Water Temperature
One of the main advantages of tankless water heaters is their ability to supply a steady stream of hot water. If you find the temperature fluctuating—going from hot to lukewarm or even cold—it’s a clear sign something’s not quite right. Mineral buildup, faulty sensors, or a failing heating element could be to blame. Ignoring these issues won’t just result in uncomfortable showers; it can also lead to more serious damage over time.
- Reduced Water Flow
If your hot water pressure suddenly drops, it might be due to a clogged or malfunctioning component within the heater. Tankless water heaters in St. George often contend with hard water, which can lead to mineral and calcium buildup. This buildup can restrict the flow of water, resulting in lower pressure. Our team can flush the system to remove sediment and help restore your water flow.
- Unusual Noises
Tankless water heaters are generally quieter than their traditional tank-based counterparts. That’s why rumbling, popping, or hissing sounds should raise a red flag. These noises can indicate trapped air, loose parts, or scale buildup. Addressing the issue early with a thorough inspection will help you avoid costlier repairs later.
- Error Codes on the Display
Many modern tankless water heaters have digital displays that show error codes when something isn’t functioning properly. If you spot an unfamiliar code and can’t resolve it by resetting the system, it’s time to call us for professional tankless water heater repair in St. George. Ignoring error codes can lead to reduced efficiency, higher energy bills, and potential damage to the unit.
- Rising Energy Bills
Tankless water heaters are known for energy savings, but a malfunctioning unit can cause your utility costs to rise unexpectedly. When the system struggles to reach or maintain the desired temperature, it may work overtime, increasing your energy usage. If you’ve noticed an unexplained spike in bills, a service check is likely in order.
- Visible Leaks or Rust
Although leaks are less common with tankless units, they can still occur around valves, fittings, or internal components. Rust, corrosion, or dripping water could point to a serious issue. If left unaddressed, even a small leak can lead to water damage or mold growth. It’s best to schedule a professional assessment at the first sign of moisture around your system.
- Age and Lack of Maintenance
Tankless water heaters can last up to 20 years with proper care. However, neglecting routine maintenance will shorten that lifespan significantly. If your unit is getting older and hasn’t been serviced recently, you’re at greater risk for problems. Regular inspections and descaling are essential—especially given St. George’s hard water conditions—to keep your system operating smoothly.
