Heatline Diverter Valve Repair Kit

Heatline Diverter Valve Repair Kit (3003202082 | D003200017 | D003202082) The Heatline Diverter Valve Repair Kit (Part Nos: 3003202082, D003200017, or D003202082) is a specialized internal component service set engineered for the classic brass-bodied 3-way diverter valves used across major Heatline combination boiler platforms. This comprehensive overhaul kit contains the primary pressure-sensing rubber diaphragm, front bypass seals, pushrods, and high-tolerance O-rings. By servicing the worn internals of the existing valve body, this kit restores the mechanical capability required to smoothly alternate primary heated water between the domestic plate heat exchanger and the central heating radiator network. Flow Activation Recovery: Restores the dynamic pressure responsiveness of the internal diaphragm, ensuring the boiler instantly detects a tap opening and fires for hot water. Rad-Bleed Prevention: Replaces degraded internal pushrod seals and gaskets to prevent thermal leakage (hot water escaping into the radiators when you only want domestic hot water). Industrial-Grade Rubber Compounds: Features an upgraded elastomeric diaphragm engineered to endure high-temperature primary cycles and resist chemical degradation from central heating sludge. Cost-Efficient Overhaul: Provides a professional-grade repair method to rebuild the internal mechanical block, saving the time and high expense of swapping the entire brass manifold structure. Compatible Models: Heatline Compact C24 — 47-157-06 Heatline Compact C28 — 47-157-07 Heatline S 24 Compact (2002–2007) — 47-157-02 Heatline S 30 Compact (2002–2007) — 47-157-03 Heatline Solaris 24 PC (2007–2009) — 47-157-04 Heatline Solaris 30 PC (2007–2009) — 47-157-05 Heatline Hydroline B24 (2003–2007) — 47-157-18 Heatline Vizo 24 (2002–2008) — 47-157-08 Glow-worm / Heatline Diverter Valve Repair Kit (3003202082 | D003200017 | D003202082) The Glow-worm / Heatline Diverter Valve Repair Kit (Part Nos: 3003202082, D003200017, or D003202082) is a precision-engineered internal component overhaul set designed for the classic brass-bodied 3-way diverter valves used across several entry-level, cost-efficient boiler platforms produced under the Vaillant Group umbrella (including Heatline and Glow-worm badged models). This kit features a high-sensitivity rubber diaphragm, pushrods, gland nuts, and specialized O-rings. By replacing these core internal wear parts, the valve can accurately respond to mechanical pressure drops, smoothly shifting primary heated water between central heating and domestic hot water modes. Instant Flow Detection: Replaces stretched or split diaphragms to restore immediate pressure-sensing capability, ensuring the boiler fires the moment a domestic hot water tap is opened. Thermal Isolation Protection: Features high-tolerance pushrod seals that prevent primary heat from bleeding into the radiator network during dedicated hot water operation. Resilient Materials: Utilizes reinforced elastomeric rubber and high-grade metal components designed to withstand constant mechanical friction, high temperatures, and system chemical inhibitors. Targeted Mechanical Rebuild: Allows for a clean, comprehensive internal service of the existing brass valve housing, eliminating the high cost and labor of replacing the entire manifold structure.
