Most Common Tankless Water Heater Issues

Tankless water heaters are always a smart choice because of their energy-efficient properties and the ability to supply nearly limitless hot water. However, the newer technology of the tankless water heater could make it more complicated to identify and solve potential issues.

 

While most on-demand water heaters will last you up to 20 years with proper maintenance, some common mistakes can reduce performance and require immediate repairs. Overusing the tankless water heater or poor installation are the most common issues, but let’s look at other common causes of these problems.

 

Common Causes of Tankless Water Heater Issues

 

Here are the most common causes of tankless water heater issues:

 

1.   Malfunctions Due to High Temperatures

 

You should do your best to avoid computer-generated shutdowns with tankless water heaters because they can create a significant problem. If the exhaust from the heaters is extremely hot, it must be immediately and adequately vented. The heater may be turned off automatically if the computer detects that the venting is restricted. This sort of issue is frequently caused by vent tubes that are excessively long or twisted.

 

2.   Too Much Water Activity

 

Using multiple faucets puts a strain on your heater that can be difficult to undo. Without sufficient gas, your water heater may shut down, leaving you with a malfunctioning heater. In some cases, you’ll need to upgrade the natural gas line to your house to handle the load. Talk to your plumber about finding a gas line that can handle the amount of water your household typically uses. You’ll need to ensure that your system has sufficient gas supply to perform effectively and deliver enough hot water to your property.

 

3.   Scale Buildup

 

Just as with any other residential maintenance, water heater maintenance is imperative. When dirt, debris, and minerals such as calcium and magnesium build up in your system over time, you’ll have a significant problem. You should notice a light switch on your system to indicate a problem, but if not, you can contact a local plumber for help.

 

This issue typically reduces the water heater’s efficiency and increases the risk of your system breaking or being damaged prematurely. A warranty probably won’t cover this type of malfunction. To prevent this from happening, you will need to buy a water softener or install a scale filter. You can also use the vinegar-water solution as a more straightforward substitute. Some tankless water heater models may need to be serviced by a professional plumber regularly if the mineral buildup is an ongoing problem.

 

4.   Water Heater Corrosion

 

Tank-type water heaters rust more quickly than tankless heaters. Still, corrosion poses a significant threat if it does occur. If the condensed water drips over the burner, it can deteriorate and cause a gas supply obstruction. Even if it’s unlikely, a tankless water heater’s delicate microprocessor could be fooled by a minor constraint and shut down the entire system.

 

Incorrect installation of the heat exchanger can lead to early corrosion damage. This shouldn’t be a concern for the heater’s lifespan, provided it’s placed correctly. However, a damaged heater may require a pricey replacement.
