Tankless Water Heater Repair 101

Have you ever wondered if there’s a more energy-efficient way to maintain hot water in your home? The good news is that tankless water heaters are made for this purpose. Naturally, you’re wondering how this tankless water heater works and what you’ll need to prepare for in terms of a possible tankless water heater repair. Read this guide to get an introductory understanding of tankless water heaters.

How Does A Tankless Water Heater Work?

First, let’s dive into how a tankless water heater works. As the name suggests, these water heaters don’t rely on a tank. Instead, they provide a constant supply of water on-demand that heats up as it moves through the system. The water is heated by the heating elements it flows through.

5 Types Of Tankless Water Heater Repairs

Now that you know how a tankless water heater works, you’ll have a better idea of each kind of tankless water heater repair. Here are the five types of repairs you’ll need to be aware of for a tankless water heater.

1. Mineral Buildup

The first tankless water heater repair to be aware of involves mineral buildup in the system. This buildup happens when calcium and magnesium get heated up enough to form a scaly substance. Luckily, if you consistently monitor your tankless water heater and keep the filter clean by flushing out the heater at least once a year, you shouldn’t have to worry about this becoming a problem.

2. System Errors

Most tankless water heaters include a panel that allows you to control the settings and informs you of any problems with system error codes. You can use your user manual to interpret what the error code tells you, allowing you to know the issue with little to no hassle. You’ll be able to know whether or not you can troubleshoot it yourself or if you’ll need to call a technician for this tankless water heater repair.

3. Ignition Failure

The next type of tankless water heater repair to know about involves ignition failure. The cause of this ignition failure could be due to a propane shortage or a faulty gas valve. If it’s the former, ensure that there’s enough propane for your heater to ignite a flame and heat your water. Call a technician to help return your tankless water heater to working order if it’s the latter.

4. Ventilation Blockage

A major tankless water heater repair involves unclogging any ventilation blockages. These blockages can be the result of sediment or mineral buildup, as well as any kind of debris getting in the way of the air supply line. When these lines are blocked, your tankless water heater can easily overheat, resulting in a fire. You can clear the source of the blockage yourself if you have the necessary equipment and experience. If not, leave this job to the professionals.

5. Inconsistent Temperature

Finally, the last type of tankless water heater repair to be aware of addresses inconsistent temperatures. The lack of consistency in water temperature can be attributed either to ignition problems or it could just be a case of the hot water supply being used up and needing to recharge. If the water doesn’t return to being hot after a while, call a technician to figure out what’s happening.
