As a genuine Glow‑Worm spare part, the S1005600 de‑aerator 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‑locked circuits.
Over 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 or clogged de‑aerator may result in increased noise, reduced circulation, frequent need for manual bleeding, and additional wear on the pump and heat exchanger. Replacing a worn or compromised automatic de‑aerator with this OEM component restores reliable air extraction, improves overall system efficiency, and helps maintain silent, stable operation throughout the heating season. Because this part interfaces directly with the boiler’s hydraulic circuit, installation and testing should be carried out by a qualified heating engineer to ensure correct placement, secure connections, and compliance with safety and performance standards.
Glow-Worm provide a 1 year warranty on all genuine spare parts. Electrical Deals Direct now sells a wide range of spare parts. If you cannot see the item you require on our website, please call 01934 253600 or email [email protected] for more information.
This is a compatible Glow-Worm product, designed to match the original specifications and provide reliable performance.

Standard delivery for all orders over £150 ex-VAT are free of charge.
If we can speed this up, we will, but you can also select Express Delivery when you check out and get your purchase more quickly (usually the next working day, subject to a 1pm cut-off): there is an extra charge for this ranging from £5 to £29.99 depending on the products you are buying.
We partner with several of the best UK carriers (such as TNT, Royal Mail, DPD etc) depending on the type of product and the warehouse it is coming from, and also with some pallet companies for larger items. All of these operate during normal Monday – Friday working hours, and we expect all deliveries to arrive in 5 days. For more details checkout this page.
For all Gledhill Cylinders, a flat delivery charge of £27.50 (ex-VAT) applies, regardless of order value or delivery method. This will be added automatically at checkout.
Having to return a product because it doesn’t fit, or is not what you wanted, is really annoying! To try and make sure this isn’t necessary we have lots of helpful advice on our site, and you should feel free to call our experts on the number above to check if you are in any doubt at all – we’re always happy to help.
But if you do, don’t worry, just contact us and we’ll get it sorted (note that for trade customers there may be a restocking fee). If you need it, we can usually arrange the carrier to pick it up.
