How to Prevent Frozen Pipes in Your Heating System

1. Maintain a Consistent Temperature

• Keep your thermostat set to at least 55°F, even when you’re away.
• Avoid drastic temperature drops at night.

2. Insulate Exposed Pipes

• Use pipe insulation or heat tape on pipes in unheated areas like basements, crawl spaces, and attics.
• Seal gaps or cracks around pipes with caulking or foam insulation.

3. Allow Air Circulation

• Open cabinet doors under sinks to let warm air reach pipes.
• Keep interior doors open to maintain even heat distribution.

4. Keep Water Flowing

• Let faucets drip slightly to prevent stagnant water from freezing.
• Running water, even at a trickle, helps prevent ice buildup.

5. Service Your HVAC System Regularly

• Have a professional inspect your heating system before winter.
• Check for signs of leaks, pressure drops, or reduced efficiency.

6. Use Space Heaters in Vulnerable Areas

• If certain areas of your home are prone to freezing, use space heaters cautiously to keep the temperature above freezing.

7. Install a Pipe Heating Cable

• A thermostatically controlled heating cable can keep pipes warm in extreme conditions.

Troubleshooting Frozen Pipes

If your pipes freeze:

• Turn Off Water Supply: Shut off the main valve to prevent bursting.
• Apply Heat: Use a hairdryer or heating pad on the affected pipe. Avoid open flames.
• Call a Professional: If you can’t locate or thaw the frozen section, contact an HVAC technician.

Conclusion

Preventing frozen pipes in your heating system is crucial for avoiding costly damage and maintaining efficiency. Regular maintenance, insulation, and temperature control are key strategies. If you suspect frozen pipes, act quickly to minimize potential damage.
