Maintenance Myths: What Tankless Water Heaters Really Require

Tankless water heaters offer endless hot water and energy efficiency, but many homeowners wonder about their upkeep. There are a lot of misconceptions about what these systems need to run correctly. Some people think they are maintenance-free, while others believe they require constant attention. As the trusted local expert in water heater repair in Scottsdale, AZ, Trident Plumbing & Drain shares some insight so you can get the most out of your system and avoid costly breakdowns.

Tankless Water Heaters Do Not Need Flushing

Actually, they do. The most important part of tankless water heater maintenance is flushing the system. This process removes mineral buildup, which is a big concern in areas with hard water. Over time, calcium and magnesium deposits can form on the heat exchanger. This scale reduces the unit’s efficiency and can cause it to fail.

A professional flushing procedure uses a solution to break down these minerals. The frequency depends on your water quality. Without it, the flow of water can be restricted, and your tankless water heater may not heat water as quickly as it should.

Occasional Water Heater Services Are Enough

Most manufacturers recommend professional service once a year. This check-up is more than just a flush. A professional will inspect the entire system, including the vent pipes, gas or electric connections, and the heat exchanger. They will check for any leaks, cracks, or loose parts. A certified technician can spot small issues before they become major problems. A yearly service plan can protect your investment and ensure your tankless water heater operates at peak efficiency. It’s a small cost that can prevent the need for a full water heater replacement down the road.

Anyone Can Perform Tankless Water Heater Maintenance

While some online guides may suggest DIY flushing, it is best to leave this to a professional. The process involves handling chemicals and working with water and gas or electricity. Any mistakes can be dangerous and could void your warranty. Incorrectly flushing the system might not remove all the scale or could damage the internal components, prompting the need for new water heater installation.
