How do I thaw a frozen boiler condensate pipe?

To thaw a frozen boiler condensate pipe, first turn off the boiler for safety. Locate the frozen section, usually outside or in an unheated area. Gently apply warmth using a hot water bottle, warm cloths, or a hairdryer on a low setting. Avoid using boiling water or open flames. Once thawed, reset the boiler and check for proper drainage to prevent refreezing.
