NEW WATER HEATER CARE

After installing a tankless water heater, regular maintenance is essential to keep it running efficiently and extend its lifespan. Here are some key care instructions:

1. Flush the System Annually

  • Mineral buildup, especially in areas with hard water, can reduce efficiency.
  • Use a descaling solution or white vinegar to flush out limescale and sediment.
  • Follow manufacturer instructions or hire a professional for descaling.

2. Clean the Inlet Filter

  • Many units have an inlet water filter that traps debris.
  • Remove and rinse the filter periodically to prevent clogging.

3. Check the Venting System

  • Ensure the exhaust vent is free of blockages or obstructions.
  • Look for any leaks or damage in vent pipes.

4. Inspect the Burner and Heat Exchanger

  • Dust and debris can accumulate over time.
  • Clean the burner and inspect for soot or corrosion.

5. Test the Pressure Relief Valve

  • If your unit has one, test it occasionally to ensure it releases pressure properly.

6. Keep the Area Around the Heater Clear

  • Maintain at least a 2-foot clearance around the unit for proper airflow.
  • Avoid storing flammable materials nearby.

7. Monitor for Error Codes

  • Tankless water heaters have digital displays that show error codes.
  • Refer to the manual to troubleshoot or call a professional if needed.

8. Check Gas and Water Connections

  • Periodically inspect for leaks or loose connections.
  • If you smell gas, turn off the supply and call a professional immediately.

9. Install a Water Softener (If Necessary)

  • Hard water can cause scale buildup faster.
  • A water softener can help reduce maintenance needs.

10. Winterize if Needed

  • In cold climates, insulate exposed pipes to prevent freezing.
  • If shutting down for an extended period, drain the unit per manufacturer guidelines.

By following these care instructions, you can keep your tankless water heater operating efficiently for many years. 

After installing a tanked water heater, regular maintenance is crucial to ensure efficiency, longevity, and safety. Here are the key care instructions:

1. Flush the Tank Annually

  • Sediment buildup can reduce efficiency and damage the tank.
  • Drain and flush the tank once a year to remove mineral deposits.
  • In areas with hard water, flushing may be needed more frequently.

2. Test the Temperature & Pressure (T&P) Relief Valve

  • The T&P valve prevents excessive pressure buildup.
  • Lift the valve’s lever briefly to ensure water flows out and stops when released.
  • Replace the valve if it does not function properly.

3. Check and Replace the Anode Rod

  • The anode rod prevents rust inside the tank by attracting corrosive elements.
  • Inspect it every 2–3 years and replace it if it is heavily corroded.
  • A good anode rod extends the life of the water heater.

4. Adjust the Temperature Setting

  • Keep the thermostat set to 120°F to balance efficiency and safety.
  • Higher temperatures increase the risk of scalding and energy costs.

5. Insulate the Tank and Pipes

  • Use an insulation blanket around the tank to reduce heat loss.
  • Insulate hot water pipes to maintain water temperature and reduce energy use.

6. Check for Leaks and Rust

  • Regularly inspect around the base of the tank and connections for leaks or rust.
  • Small leaks can indicate bigger problems, so address them early.

7. Maintain Proper Venting (Gas Heaters)

  • Ensure the vent pipe is free from blockages and securely attached.
  • A clogged vent can lead to dangerous carbon monoxide buildup.

8. Inspect the Burner (Gas Heaters)

  • Check for soot buildup or yellow flames, which may indicate incomplete combustion.
  • A blue flame is ideal; if it’s orange or yellow, get it serviced.

9. Check the Electrical Elements (Electric Heaters)

  • If the water isn’t heating properly, test and replace faulty heating elements.
  • Ensure wiring connections are secure.

10. Prepare for Cold Weather

  • If the heater is in a cold area (garage, basement), insulate exposed pipes to prevent freezing.
  • If shutting down for an extended period, drain the tank to avoid damage.

Regular maintenance will extend the life of your tanked water heater and help it operate efficiently.
