To fix frozen heating pipes, first use a hairdryer or heat gun to gently warm the pipe, starting from the faucet end. Apply heat until water flows, then insulate exposed sections with foam or insulation tape. Avoid open flames, as they can cause sudden pressure buildup. If the pipe is completely frozen, shut off the heat source, let it thaw slowly, and contact a licensed plumber.

The primary cause of frozen pipes is rapid temperature drops, which force water to expand and rupture pipes. Insulation reduces heat loss by up to 90%, according to the U.S. Department of Energy, lowering the risk of freezing. Data from the Insurance Institute for Highway Safety (IIHS) shows that frozen pipes account for approximately 25% of winter-related home insurance claims, with average repair costs exceeding $5,000. Thawing methods like heat application work because they gradually increase temperature, preventing ice crystals from forming. However, improper use of torches or excessive heat can cause metal warping or leaks. The National Association of Home Insurers (NAHI) emphasizes that proactive insulation and slow thawing are critical to avoiding costly damage. Over 15% of U.S. households experience pipe freezes annually, costing billions in repairs, underscoring the importance of preventive measures.

By combining immediate heat application with insulation, homeowners can mitigate risks effectively. Always prioritize safety and consult professionals for severe cases to prevent long-term structural damage.
