4 Common Tankless Water Heater Problems Faced By Homeowners


Tankless water heaters have transformed the water heating for households. They’re efficient and conserve energy far better when compared with a traditional water heater. A tankless water heater has no storage tank and supplies constant hot water at the rate of 2–5 gallons per minute.

But isn’t on-demand hot water supply convenient? Well, not for long. There are a number of factors that can disturb your continuous supply of hot water and force you to take cold showers.

Tankless water heaters require proper maintenance to function properly. Here are some common tankless water heater problems that every homeowner faces at one point or another.

1. Mineral buildup:

It’s one of the most common issues with any hot water heater and depends on the hard water supply you get. If your water supply contains a high amount of calcium and magnesium, these components will deposit around the internal piping of your system, causing a number of issues. This may damage your appliance if not addressed in time. Some heaters have integrated sensors to detect mineral buildup. They alert the user when the scaly buildup has increased beyond a certain limit.

To eliminate the buildup, flush your water tank once every year. Try using a water softener to reduce the damaging effects of hard water.

2. Low water pressure:

An unstable flow of water is the result of inadequate water pressure. This is a frustrating situation and usually occurs due to the lack of gas or power supplied to the system. Check your propane tank to make sure it’s not empty.

3. System overload:

If you’re drawing water due for multiple appliances, your water heater may get over-exhausted. It won’t be able to meet the hot water requirements of your household and may shut down completely. It’s a common issue and can occur at any time. If this is a frequent problem in your home, consider an upgrade and buy a larger one that can facilitate your entire family.

4. Exhaust blockage:

If your water heating system displays this message, it’s trying to address a problem with the venting system. The message shows that the fuel isn’t combusting properly. Check the vent pipes for any damage and make sure they’re connected tightly to the system. Contact a professional to detect any possible leaks. Another reason for this issue is a blocked pipeline. Address the issue ASAP to avoid any severe damage.
