Leaky Troubles: Causes and Solutions for Tankless Water Heater Leaking

Understanding Tankless Water Heaters

As a homeowner, you may encounter various issues with your household appliances, one of them being a ‘tankless water heater leaking’. To better understand this issue, it’s important to first gain a basic understanding of tankless water heaters and their lifespan.

Basics of Tankless Water Heaters

Tankless water heaters, also known as on-demand or instantaneous water heaters, provide hot water only as it’s needed. They don’t produce the standby energy losses associated with traditional storage water heaters, which can save you money.

They heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit. A gas burner or an electric element heats the water. As a result, tankless water heaters deliver a constant supply of hot water.

There are several factors to consider when choosing a tankless water heater, such as its sizing and whether it’s electric or gas. You can learn more about these considerations in our articles on tankless water heater electric vs gas and tankless water heater sizing.

Lifespan of Tankless Water Heaters

Tankless water heaters typically have a life expectancy of about 20 years, according to bradfordwhite.com. However, the actual lifespan can vary based on factors such as water quality, regular maintenance, and proper installation.

To ensure the longevity of your tankless water heater, regular maintenance is crucial. This includes periodically checking for leaks, which is one of the common issues you might encounter with your tankless water heater.

If you’re facing issues such as your tankless water heater not heating water, or it not turning on, it’s important to troubleshoot these issues promptly to prevent further damage. You can refer to our tankless water heater troubleshooting guide for assistance.

Understanding the basics and lifespan of tankless water heaters can help you make informed decisions when dealing with issues such as leaking. It also helps you understand the importance of proper maintenance and installation, which you can learn more about in our tankless water heater installation guide.
