A vehicle or stationary liquid, water or oil tank heater teaches that a hot fluid may be passed through a metal body placed in the water piping or in the vacuum piping, thereby melting any ice in the system and preventing further freezing. The system may be advantageously used with manifolds, valves, scrubbers, pipes or the water tank itself. The coolant flow path may be optimized for ease of production and/or efficient heat transfer. The invention may be used with an external source of hot liquid, or it may be used with a cuff which may slipped over any of a variety of devices in need of de-icing.
