Tankless water heaters provide energy efficiency and consistent hot water, making them a popular choice for homes in Arlington Heights. However, as winter approaches, these systems require proper care to ensure peak performance during the colder months. Flushing your tankless water heater is a critical part of water heater maintenance and helps prevent damage caused by mineral buildup or freezing temperatures.
Follow these step-by-step instructions to prepare your tankless water heater for winter and protect your investment.
Step 1: Turn Off the Power Supply
Safety is key when performing any maintenance. Begin by turning off the power supply to your tankless water heater. Most units have a dedicated circuit breaker or power switch. If your system runs on gas, ensure the gas supply is also turned off.
Step 2: Shut Off the Water Supply
Next, shut off the cold water inlet and hot water outlet valves to isolate the unit from your home's plumbing system. This prevents water from flowing through the heater during the flushing process.
Step 3: Drain the System
Locate the drain valve and connect a hose to direct water safely into a bucket or sink. Open the valve to drain any remaining water from the system. This step helps remove sediment that can reduce efficiency and cause clogs.
Step 4: Flush with a Descaling Solution
Prepare a descaling solution recommended by your tankless water heater manufacturer. Connect a submersible pump to the cold water inlet and place both the pump and drain hose into a bucket containing the solution. Run the solution through the system for 30–45 minutes to dissolve mineral deposits.
Step 5: Rinse the System Thoroughly
After descaling, flush the unit with clean water to remove any remaining solution. Open the cold water inlet valve and let water run through the system until it flows clear. This step ensures no chemical residue remains that could damage the unit or affect water quality.
Step 6: Inspect for Damage and Insulate Pipes
Inspect your unit for signs of wear or damage, such as rust, leaks, or unusual noises. Additionally, insulate the pipes leading to and from the water heater to protect them from freezing during Arlington Heights' frigid winters.
Step 7: Restore Power and Test
Once maintenance is complete, close the drain valve, turn on the water supply, and restore power or gas to the unit. Run hot water through a faucet to ensure the system is functioning properly.
Why Flushing Matters in Arlington Heights
Hard water is common in Arlington Heights, and its high mineral content can lead to limescale buildup inside your tankless water heater. Flushing the system helps remove these deposits, ensuring optimal efficiency and extending the lifespan of your unit. Regular maintenance also reduces the risk of winter-related issues, such as freezing or sudden breakdowns.
