Glow-Worm S1005600 Automatic De-Aerator\n\nAs a genuine Glow\u2011Worm spare part, the S1005600 de\u2011aerator is manufactured to original equipment specifications for internal geometry, venting performance, and material durability under continuous heating system conditions. Efficient removal of dissolved and trapped air is essential for optimal hydraulic performance: air within the system can create resistance to flow, reduce the effective pumping head, and contribute to uneven heating in radiators or underfloor circuits. By automatically eliminating air, this component supports more uniform heat distribution, improves pump efficiency, and helps prevent common issues like cold spots, erratic thermostat behaviour, or unnecessary boiler cycling that can result from air\u2011locked circuits.\n\nOver time, air separation devices can become partially obstructed by debris, corrosion particles, or scale, which can reduce their effectiveness and allow air accumulation to persist. A failing.
