A tankless water heater is an excellent upgrade for your home that can make it more energy-efficient. This type of water heater doesn’t store water in a tank, which reduces the risk of leaks. But tankless units are not immune to breakdowns or wear and tear. Units that go without maintenance are the ones that tend to experience the most problems. If you notice any of the following warning signs, you need to call Arctic Air Home Services to book service.
1. Water Never Gets Fully Hot
The water never getting fully hot is a clear sign that something is wrong with your water heater. This problem not only leads to uncomfortable, lukewarm showers but also indicates failing components. There could be a heating element issue, ignition malfunction or mineral buildup affecting the heat transfer process.
2. Mineral Buildup Signs or Scaling Issues
Many properties in Sarasota and Manatee County have hard water that increases calcium and magnesium buildup inside their water heaters. When scale builds up on the heat exchanger, you may notice reduced water flow. If the scale isn’t removed, it can cause the equipment to overheat and completely shut down. This is why regular flushing is so important for water heaters, even tankless models.
Other signs of mineral buildup in tankless water heaters:
- Fluctuating water temperatures
- Visible white mineral deposits
- Scale residue on fittings
- Low hot water pressure
- Delayed hot water delivery
3. Ignition or Flame Sensor Failures
To heat water on demand, tankless water heaters use electronic ignition and flame sensors. But the device may have trouble starting or turn completely off if certain parts break or become dusty. Sensor misalignment, gas supply problems and buildup on ignition components are common culprits for this type of malfunction.
4. Rising Energy Bills Without Explanation
If your energy bill keeps going up despite no change in your water use, the system may be supplying hot water less efficiently. You may be taking longer showers without realizing it while waiting for the water to warm up. Dishwashing and laundry may also be taking longer, using more water and energy. We can inspect the equipment to see whether it’s operating efficiently. It may need a flush or repair to restore its normal operation.
5. Delayed Hot Water Delivery Times
One of the main reasons that people upgrade their homes with tankless water heaters is because of their on-demand delivery. There is no need to wait for stored hot water because the system heats water instantly. If you keep experiencing a delay in the delivery of hot water, this is a sign of trouble. There could be a water flow restriction, an inaccurate sensor reading or some type of internal damage. If you don’t get the problem fixed quickly, it may get worse until the unit quits working altogether.
6. Unusual Noises Coming From Unit
Tankless water heaters don’t produce loud noises when they operate. You may hear a soft humming or brief clicking noise, but these are no cause for concern. They occur because of normal operation. However, if you hear banging or rattling noises, you need to take fast action. Popping noises mean there’s mineral buildup that requires flushing to remove. Rattling sounds typically mean there’s a loose component. Shutting the system off until it receives service is the best way to prevent further damage.
7. Metallic or Burning Odors Present
Your tankless water heater should never emit any type of strange odor. If you notice a metallic smell, this may suggest corrosion on the heat exchanger or other internal components. Electrical overheating can lead to burning smells that are similar to plastic or rubber. Calling for service is the smartest way to keep the home safe and protect the system from additional damage.
8. Rusty or Discolored Hot Water
Your water supply should remain clear at all times. If it’s rusty, brown or cloudy, this is another indication of corrosion inside the unit. We may be able to flush the system or replace internal components to fix the discolored water problem. Some homes benefit from installing a water filtration system to add extra protection for plumbing and appliances. This is especially helpful for homes with hard water.
9. Frequent System Resets Required
If you’re constantly having to reset the water heater, you need to have it serviced. An efficient unit will operate normally without you having to perform frequent resets. We’ll be able to tell whether it’s a sensor issue, electrical fault or faulty control board causing the shutdowns.
