Full protection, whatever the weather: With an IP68 protection rating, the Flow Wire keeps pipes safe from frost and freezing temperatures in gardens, homes, and outbuildings — buried underground or fully exposed, it handles everything the British winter throws at it.
Switches itself on and off so you don't have to: The built-in thermostat activates the cable automatically when temperatures fall below 6 °C and cuts out again once they rise above 13 °C — completely hands-free frost protection throughout the cold season.
Uses energy only when there's a real risk of frost: Because the Flow Wire is self-regulating, it adjusts its output to match actual conditions rather than running at full tilt all winter — delivering 16 W per metre only when the temperature demands it.
Fits around bends, joints, and awkward runs: The flexible cable conforms easily to straight pipe sections, curves, and fittings alike — so you can protect garden taps, external supply lines, and outbuilding connections regardless of the pipework layout.
The right size for shorter pipe runs: At 4 m of heating cable with a 1.8 m mains lead, the Flow Wire is ideal for single connections and compact outdoor areas — no overspending on cable you don't need, and no cutting required.
Product description
A burst pipe in January is one of the most expensive things that can happen to your home — and one of the most preventable. The Klarstein Flow Wire heating cable wraps around your outdoor pipes and keeps frost at bay all winter, without you having to lift a finger.
The clever part is how it works: the cable activates automatically when the temperature drops below 6 °C and switches itself off again once it climbs back above 13 °C. You only use electricity when it's actually needed. At 16 W/m, it delivers enough heat to protect pipes even during a prolonged cold snap — and at 4 m long, it's perfectly sized for shorter pipe runs, individual connections, or compact outdoor areas like a garden tap or outbuilding supply.
Built to handle the outdoors year-round, the Flow Wire carries an IP68 protection rating, so it can be buried in soil, set in concrete, or left exposed to the elements without issue. The silicone insulation copes with mechanical stress, and the UV-resistant, weatherproof housing means it won't degrade sitting outside between winters.
Whether it's a garden water pipe, an external tap, or the supply line to a garage — anywhere frost damage is a risk, the Flow Wire pays for itself in the very first cold season.
Get yours before the cold sets in and give your pipes the protection they deserve.
