To defrost a tankless water heater in winter, first, shut off the water and power supply. Next, use a hairdryer or heat tape to gently warm the pipes and the unit. Focus on the valves and connections, as these are prone to freezing. Never use an open flame to thaw your heater. Once thawed, slowly restore water flow to ensure no leaks are present. It's a good idea to insulate your pipes and water heater to prevent future freezing.
