Essential Services for Maintaining a Tankless Water Heater

Tankless water heaters, also known as on-demand water heaters, offer a compact, energy-efficient solution for providing hot water. Unlike traditional tank-style heaters, they heat water only when needed, reducing energy waste and saving space. However, tankless water heaters require specific services and maintenance to ensure optimal performance and longevity. Understanding these needs can help you keep your system running smoothly and efficiently. 

Regular Descaling

Descaling is one of the most critical maintenance tasks for a tankless water heater. Over time, minerals from hard water can accumulate inside the heat exchanger, reducing the unit’s efficiency and performance. Descaling involves flushing the system with a descaling solution to remove these mineral deposits. This process helps maintain efficient heat transfer, prevents overheating, and extends the lifespan of your unit. Depending on water hardness, descaling should be performed annually or semi-annually.

Routine Filter Cleaning

Tankless water heaters typically have filters that prevent debris and sediments from entering the system. These filters need to be cleaned or replaced regularly to ensure the proper flow of water and prevent clogging. Cleaning the filters helps maintain the heater's efficiency and prevents potential damage caused by obstructions. Check the manufacturer’s guidelines for the recommended frequency of filter cleaning.

Venting System Maintenance

The venting system is essential for safely expelling combustion gases for gas-powered tankless water heaters. Regular maintenance involves checking for obstructions, leaks, or corrosion. The technician will ensure that the venting system is properly connected and functioning, preventing the risk of dangerous gas buildup or carbon monoxide leaks. Proper venting is critical for the safe operation of gas-powered units.

Check Water Pressure

High water pressure can put undue strain on your tankless water heater, leading to potential damage and reduced lifespan. Regularly checking and regulating the water pressure is important to ensure that it stays within the recommended range specified by the manufacturer. If the water pressure is too high, a pressure-reducing valve can be adjusted to protect the system from damage.

Verify Temperature Settings

The temperature settings on your tankless water heater should be verified regularly to ensure they are set to the desired level. Overheating or excessively high temperatures can cause discomfort and potential scalding, while too-low temperatures may result in insufficient hot water. Ensuring the temperature settings are accurate and adjusted to your needs helps maintain a comfortable and efficient hot water supply.

Inspect and Maintain Electrical Components

Inspecting and maintaining electrical components is crucial for electric tankless water heaters. This includes checking the electrical connections, wiring, and control panels for any signs of wear or damage. Regular maintenance ensures the electrical components function correctly and safely, preventing potential electrical hazards and ensuring reliable operation.
