How to Handle and Prevent Heating System Freezing During Severe Cold Snaps with Newton Heating and Plumbing Tips

by

During severe cold snaps, heating systems are at risk of freezing, which can lead to costly repairs and discomfort. Newton Heating and Plumbing offers essential tips to help you handle and prevent your heating system from freezing during the coldest months.

Understanding Why Heating Systems Freeze

Heating systems can freeze when water inside pipes or components drops below freezing temperatures. This is especially common in unheated areas like basements, attics, or outdoor pipes. When water freezes, it expands, potentially causing pipes to burst or damage to the system.

How to Handle Freezing Issues

If you suspect your heating system is freezing or has frozen, act quickly:

  • Turn off the heating system to prevent further damage.
  • Open faucets connected to the affected pipes to allow water to flow and relieve pressure.
  • Use a hairdryer or heat lamp to gently thaw frozen pipes, starting from the faucet and working back toward the frozen section.
  • Do not use open flames or high-heat devices, as they can cause pipe damage or fires.
  • If you cannot thaw the pipes safely, contact a professional plumber immediately.

Preventative Tips from Newton Heating and Plumbing

Prevention is key to avoiding freezing issues. Newton Heating and Plumbing recommends the following measures:

  • Insulate exposed pipes with foam sleeves or wrap them with heat tape.
  • Keep interior doors open to allow warm air to circulate around pipes.
  • Allow a slow drip of water to flow from faucets during extremely cold nights.
  • Maintain your heating system regularly to ensure it operates efficiently.
  • Seal leaks around windows and doors to prevent cold air from entering unheated spaces.

Additional Tips for Severe Cold Snaps

During severe cold weather, consider the following:

  • Set your thermostat to at least 55°F (13°C) even when you’re away.
  • Install outdoor faucet covers to protect outdoor pipes.
  • If you plan to be away for an extended period, drain outdoor pipes and sprinkler systems.
  • Keep garage doors closed if water supply lines run through the garage.
  • Monitor weather forecasts and prepare in advance for cold snaps.

By following these tips from Newton Heating and Plumbing, you can minimize the risk of your heating system freezing and ensure your home stays warm and safe during the coldest months.
