Steps to Service a Tankless Hot Water Heater
1. Ensure Safety First
Before beginning any maintenance, follow these safety steps:
- Turn Off the Power: If your unit is electric, switch off the circuit breaker. If it’s gas-powered, shut off the gas supply.
- Close the Water Supply Valves: Shut off the cold water inlet and hot water outlet to stop water from flowing into the system.
- Let the System Cool Down: Allow the heater to cool if it has been in use recently to avoid burns or injuries.
2. Gather Necessary Tools and Supplies
To properly service your tankless water heater, you will need:
- A submersible pump for flushing.
- Two hoses that fit the isolation valves of your unit.
- A bucket (5-gallon capacity) to hold the cleaning solution.
- White vinegar (about 2.5 gallons) or a descaling solution specifically designed for tankless heaters.
3. Descale the Heater
Mineral buildup inside the heat exchanger can lead to inefficiency. Flushing the system removes these deposits:
- Attach Hoses: Connect a hose from the submersible pump to the cold water inlet and another hose from the hot water outlet back into the bucket.
- Fill the Bucket with Vinegar: Place the pump inside the bucket filled with vinegar.
- Turn on the Pump: Let it circulate the vinegar through the heater for about 60 minutes to break down mineral deposits.
- Flush with Clean Water: After descaling, run fresh water through the system to remove any remaining vinegar.
4. Clean the Inlet Filter
The inlet filter prevents debris from entering the heater, so it must be cleaned regularly:
- Locate the Filter: Usually found at the cold water inlet.
- Remove and Inspect: Take out the filter and check for debris or buildup.
- Rinse Thoroughly: Use clean running water and a soft brush if necessary.
- Reinstall the Filter: Secure it back into place once it’s clean.
5. Restore Power and Test the System
- Open the Water Supply Valves: Ensure the water flows freely through the heater.
- Turn the Power Back On: Restore the electricity or gas supply.
- Check for Leaks: Inspect all connections for any signs of leaks.
- Run the Hot Water: Test the system to ensure it is working properly.
How Often Should You Service a Tankless Water Heater?
The frequency of maintenance depends on several factors, including water hardness and usage. Generally, it is recommended to:
- Flush the system every 12 months in areas with hard water.
- Check and clean the filter every 6 months.
- Inspect gas components and venting annually.
