Signs You Need Tankless Water Heater Service
How to Know When Your Tankless Water Heater Needs Attention
It’s important to identify issues early to prevent costly repairs. Look out for these signs that your tankless water heater may need repair or replacement:
Inconsistent Hot Water Supply
If your water temperature fluctuates or doesn’t heat up properly, it could indicate an issue with the unit’s heating elements or thermostat.
Water Flow Issues
A decrease in water pressure or inconsistent flow may signal a problem with the unit’s flow sensor or water filter.
Error Codes on the Display
Many tankless water heaters have digital displays that show error codes. If you see one, it’s a sign that the system needs professional attention.

Strange Noises
Unusual noises, like hissing or gurgling, can be caused by sediment buildup or internal issues that need addressing.

you asked we answer
Tankless water heaters offer several advantages, including providing endless hot water, saving energy by heating water on demand, and taking up less space compared to traditional hot water tanks. These systems also have a longer lifespan and may lower your energy bills over time.
A well-maintained tankless water heater can last anywhere from 15 to 20 years, much longer than traditional hot water tanks. Routine maintenance, such as descaling, is necessary to ensure longevity and efficient operation.
If your tankless water heater is experiencing inconsistent water temperatures, reduced water flow, or error codes on the display, it may need professional repair. Sediment buildup or issues with the heating element can cause these problems, and regular maintenance can help prevent them.
Yes, tankless water heaters can provide hot water to multiple outlets at the same time, but the size of the unit and its flow rate will determine how many outlets it can serve simultaneously. Larger homes or higher hot water demands may require multiple units or a higher-capacity tankless water heater.
Tankless water heaters should be serviced at least once a year. Maintenance tasks include descaling the unit to remove mineral buildup, inspecting the filters, and ensuring the system is functioning efficiently. Regular maintenance will help avoid costly repairs and extend the lifespan of your system.
