A tankless water heater heats water as it passes through the unit and releases it as needed. Tankless water heaters are growing in popularity because they can save homeowners money on their energy bills and take up less space than traditional water heaters. Despite these benefits, tankless water heaters do have some problems. Here are several tankless water heater problems that require the attention of professional water heater repair services:
1. Water Temperature Fluctuations
Water temperature fluctuations can be caused by several factors, including sediment build-up, a faulty thermostat, or a blocked exhaust vent. It can also occur when the unit is not properly sized for the home, or the water supply isn't adequate.
If you are experiencing this problem, it's important to call a qualified water heater service. They will be able to diagnose the problem and fix it quickly and efficiently, starting with checking the thermostat.
2. Water Leaks
Leaks can be caused by various factors, including loose connections, improperly installed valves, or a build-up of sediment in the unit. A heater technician will first check for any obvious leaks, such as around the unit's base or in the pipes leading to and from the unit.
If there are no obvious leaks, they will then pressure test the unit to see if there are any hidden leaks. Once they have located the leak, they will repair it using a sealant or replace the affected parts.
3. Strange Noises
If you notice a banging, popping, or knocking noise, it could be due to sediment build-up in the unit. This is most likely to happen if your water heater isn't flushed regularly. Sediment can cause the burner to overheat and make loud noises.
A water heater repair service can clean out the sediment and get your unit back to working quietly and efficiently. Another possibility is that the noise is coming from a loose part. This is easier to fix with a tightening of the loose part.
4. Low Water Pressure
One common problem in heaters is low water pressure. If the water pressure is too low, it can cause the unit to overheat and shut down. A qualified water heater repair service can check the unit and ensure it receives the proper water volume.
Sometimes, the problem may be as simple as a clogged inlet screen or a loose connection. However, if the unit is older or has been damaged, it may need to be replaced. A technician will assess the situation and recommend the best course of action.
A faulty water heater can cause much discomfort because of a lack of hot water for personal and domestic use. But any fault can be fixed by a skilled technician. Call a water heater repair service if you suspect your heater has any of these problems.
