Why Cleaning and Flushing Is Important

Regularly maintaining and cleaning your tankless water heater will increase longevity and keep it in good working order.  Cleaning and flushing your tankless water heater is essential for several reasons:

Prevention of Mineral Build-Up

Over time, mineral deposits from hard water can accumulate inside the heater’s heat exchanger and pipes. This build-up reduces the heater’s efficiency, as it takes longer for water to heat up. Regular cleaning and flushing help to remove these deposits, ensuring optimal performance and efficiency.

Extended Lifespan

Mineral build-up affects the heater’s efficiency and can result in corrosion and damage to internal components. By regularly cleaning and flushing the heater, you can prevent corrosion and prolong its lifespan, helping avoid costly repairs or replacements.

Improved Energy Efficiency

Consistent maintenance ensures that your water heater works at its peak efficiency. It also lowers energy consumption and saves you money on utility bills. You’ll enjoy consistent performance and lower energy costs by keeping your unit clean and well-maintained.

Consistent Hot Water Supply

Mineral build-up can cause fluctuations in water temperature and reduced water flow. By cleaning the heater, you can ensure a steady supply of hot water all through your home. This can mean no more cold showers! 

Reduced Risk of Damage and Leaks

Mineral deposits can put added strain on the heater’s components, increasing the risk of leaks or damage. Regular tankless water heater maintenance helps to prevent these issues, ensuring safe and efficient operation.

Mineral deposits can cause your water heater to produce strange noises during operation. Flushing the unit can help reduce noise and provide a quieter home environment.

How to Clean and Flush Your Tankless Water Heater

Step 1: Turn off the power. Before you begin any maintenance work on your water heater, ensure to turn off the power supply to the unit. Safety first!

Step 2: Turn off your water supply. Find the shut-off valve near the water heater or at the main water line and turn it off to stop the water supply.

Step 3: Drain the water heater. Attach a hose to the drain valve of the heater and direct it to a drain or outside area. Open the valve to drain any remaining water from the unit completely.

Step 4: Take out and clean the filter. The majority of tankless water heaters have a filter to trap sediment and debris. Take out the filter and clean it thoroughly with water or a mild cleaning solution to ensure optimal filtration.

Step 5: Flush the heater. Fill a bucket with white vinegar or a descaling solution and attach it to the heater’s cold-water inlet valve, then open the valve to let the solution flow through the unit and dissolve any stubborn mineral deposits. Let it sit for about an hour before flushing it out with clean water.

Step 6: Reassemble and restart. Once the cleaning and flushing process is complete, reattach the filter, close the drain valve, and turn the water and power supply back on.

Keep Your Tankless Water Heater in Good Condition

As discussed, cleaning and flushing your water heater at least once a year (or as recommended by the manufacturer) is essential to remove mineral deposits and debris that can affect its efficiency and lifespan.

High water pressure can put excessive strain on your water heater and its components, leading to leaks or damage over time. Use a pressure gauge to ensure that the water pressure is within the recommended range (usually between 40 to 80 psi).

If you live in an area with hard water, think about installing a water softener. This will reduce mineral deposits in your water heater and other plumbing fixtures. This can help prolong the lifespan of your unit and improve its efficiency.

Frequently check for any signs of corrosion or leaks around your water heater, including on pipes, fittings, and valves. Dealing with leaks promptly can prevent water damage and costly repairs.

If your tankless water heater is gas-powered, ensure that the venting system is clear of debris and properly installed to prevent carbon monoxide buildup. Schedule professional inspection and maintenance of the venting system as needed.

Make sure there is adequate clearance around your water heater for ventilation and servicing. To prevent overheating, avoid storing items or blocking airflow around the unit.

Consider arranging an annual maintenance check with a qualified technician to inspect and service your water heater. They can identify any possible issues early on and ensure that your unit is operating well.

Always follow the manufacturer’s guidelines and recommendations for the maintenance and usage of your specific water heater model. Following these guidelines can help optimize performance and prevent voiding the warranty.

By following these steps and staying proactive about maintenance, you will keep your tankless water heater in optimal condition. This will ensure you consistently have hot water and limit expensive repairs or replacements down the line.
