If you live in Los Angeles, you know how essential it is to have a reliable water heater to keep your home running smoothly. Tankless water heaters are becoming increasingly popular due to their energy efficiency and on-demand hot water supply. However, like any appliance, they require regular maintenance to function optimally. In this blog, we’ll share the top 5 tips for maintaining your tankless water heater in Los Angeles, ensuring it serves you efficiently for years to come.

1. Descale Your Tankless Water Heater Regularly

Los Angeles has hard water, which means that minerals like calcium and magnesium can build up inside your tankless water heater over time. This can affect its performance and reduce its lifespan. To prevent this, it’s essential to descale your water heater regularly. We recommend scheduling a descaling service at least once a year, or more frequently if you have very hard water.

Tip: If you’re unsure how to descale your unit, it’s best to hire a professional.

2. Clean the Air Filter and Vent System

For optimal performance, tankless water heaters rely on a clean air supply. Over time, dust, dirt, and debris can accumulate in the air filter and vent system, reducing efficiency and causing the unit to overheat. Regularly cleaning these parts ensures your unit operates at its best.

Tip: Check and clean the filter at least once every six months. If you’re not comfortable doing it yourself, we can handle this for you. At

3. Flush the System Annually

Flushing your tankless water heater is a vital part of its maintenance routine. Doing so helps remove any sediment buildup and mineral deposits, which can restrict water flow and affect the heater’s efficiency. Flushing the system also helps maintain the warranty on your unit.

Tip: If you’re unsure how to flush your tankless water heater, we recommend leaving it to the experts.

4. Check the Temperature Settings

Another simple yet important maintenance task is checking your water heater’s temperature settings. If your unit’s temperature is set too high, it may strain the system, leading to increased energy consumption. On the other hand, if it’s too low, you may not get hot water when you need it.

Tip: We recommend setting your tankless water heater to 120°F for optimal performance and energy efficiency.

5. Inspect for Leaks and Signs of Wear

Regularly inspect your tankless water heater for leaks or visible signs of wear, such as rust or corrosion around the unit. Leaks can cause significant damage to your home and decrease the lifespan of your heater. Addressing issues early on can save you money on repairs in the long run.
