Warranty Coverage

Many tankless water heaters come with extensive warranty coverage, reflecting the manufacturer’s confidence in their product’s durability. Warranties typically cover parts and labor for a specified period, providing peace of mind for homeowners.

Maintenance Tips To Extend The Lifespan

1. Regular Descaling

Descaling the unit regularly is essential, especially in areas with hard water. This involves flushing the system with a descaling solution to remove mineral buildup from the heat exchanger. Most manufacturers recommend descaling every 6 to 12 months, depending on water hardness.

2. Cleaning The Inlet Filter

The inlet filter prevents debris and sediment from entering the unit. Cleaning the filter every few months ensures optimal water flow and prevents potential blockages that could affect performance.

3. Inspecting Venting And Exhaust Systems

Proper ventilation is crucial for the safe and efficient operation of gas-powered tankless water heaters. Regularly inspect the venting and exhaust systems for any blockages, leaks, or damage. Ensure that the vent pipes are properly sealed and free from obstructions.

4. Checking For Leaks

Periodically check for any signs of leaks around the unit, including water connections and gas lines. Addressing leaks promptly can prevent damage to the unit and surrounding areas.

5. Professional Maintenance

While some maintenance tasks can be performed by homeowners, it’s advisable to schedule professional maintenance annually. A qualified technician can thoroughly inspect the unit, perform necessary maintenance, and identify any potential issues before they become major problems.

Signs Of A Failing Tankless Water Heater

Decreased Hot Water Output

One of the first signs of a failing tankless water heater is a noticeable decrease in hot water output. This could be due to a variety of issues such as mineral buildup, a failing heating element, or a malfunctioning thermostat.

Fluctuating Water Temperatures

If you experience inconsistent water temperatures, it could indicate a problem with the unit. Fluctuations in temperature can be caused by issues such as clogged filters, faulty sensors, or inadequate gas supply.

Strange Noises

Unusual noises coming from the tankless water heater, such as popping, rumbling, or whining, can signal underlying problems. These noises are often associated with mineral buildup or loose components within the unit.

Error Codes

Modern tankless water heaters are equipped with self-diagnostic systems that display error codes when something goes wrong. Refer to the user manual to interpret these codes and determine the necessary steps for troubleshooting.
