As temperatures drop in Chicago, homeowners need to take extra precautions to ensure their residential water heater is ready for winter. Freezing temperatures can lead to burst pipes, reduced efficiency, and costly repairs. By following these simple steps, you can protect your water heater and keep hot water flowing efficiently all season long.
Step 1: Check the Temperature Setting
Recommended Setting: 120°F–140°F
- If the temperature is too low, your residential water heater will struggle to keep up with demand in cold weather.
- If it’s too high, it can waste energy and cause scalding risks.
What to Do:
- Locate the thermostat on your water heater and adjust it within the safe range.
- If your unit lacks a digital thermostat, use a thermometer to check the water temperature at the tap.
Step 2: Drain and Flush the Tank
Why? Sediment buildup reduces efficiency and can cause internal damage.
What to Do:
- Turn off the power or gas supply to the heater.
- Connect a hose to the drain valve and direct it to a safe drainage area.
- Open the valve and let the water run until clear.
- Close the valve and refill the tank before restoring power.
Tip: For tankless water heaters, flushing the system removes mineral buildup that could restrict water flow.
Step 3: Insulate the Tank and Pipes
Why? Insulation helps retain heat and prevents pipes from freezing.
What to Do:
- Wrap the water heater tank with an insulation blanket.
- Cover exposed pipes with foam pipe insulation, especially those near exterior walls.
- For gas heaters, ensure vents and flues remain unobstructed for safety.
Step 4: Test the Pressure Relief Valve
Why? A faulty valve can lead to dangerous pressure buildup.
What to Do:
- Lift the pressure relief valve lever and let it snap back.
- If water flows freely, the valve is working.
- If no water comes out or the valve leaks afterward, it needs replacement.
- If you’re unsure, call a professional plumber in Chicago to inspect the system.
Step 5: Inspect for Leaks or Corrosion
Why? Leaks can worsen in cold weather and lead to water damage.
What to Do:
- Check around the base of your residential water heater for moisture.
- Look for rust or corrosion on connections and fittings.
- Listen for unusual noises—popping sounds may indicate sediment buildup.
- Tip: If you notice persistent leaks, schedule repairs before winter arrives.
Step 6: Consider a Maintenance Check from a Professional
- If your water heater is over 10 years old, an expert plumber in Chicago can assess if repairs or a replacement are needed.
- Regular inspections help prevent emergency breakdowns when temperatures drop.
Conclusion
Winter in Chicago can be brutal, but preparing your residential water heater ensures hot water reliability and energy efficiency.
