Product Information
Full details
The Ideal Diverter Valve Manifold Kit (171025) is an essential replacement component designed for homeowners and heating engineers maintaining specific Ideal boiler models. Its primary function is to accurately route heated water between your central heating system and the domestic hot water supply, ensuring consistent performance. While it is a high-quality genuine part, it requires professional installation, as improper handling of boiler internal components can compromise safety and system integrity.

FAQs
Is this kit compatible with all Ideal Isar boilers?
No, it is compatible with Ideal Isar HE24, HE30, and HE35 models with serial numbers prior to XF, and the Isar M30100. Always check your specific boiler serial number.
Can I install this diverter valve myself?
No. Due to the nature of boiler repair and the necessary safety protocols involving gas and water systems, this must be installed by a Gas Safe registered engineer.
What tools are needed for this repair?
Standard plumbing tools and specialized boiler repair tools are required. Your engineer will bring the necessary equipment to drain and replace the component.
How do I know if my diverter valve needs replacing?
Common symptoms include radiators heating up when they shouldn't, slow hot water response, or visible water dripping from the manifold assembly.
Does this kit include all necessary seals?
Yes, as a genuine Ideal kit, it is designed to contain the necessary components for a standard manifold replacement for the listed models.
Troubleshooting
Hot water is lukewarm or inconsistent
The diverter valve may be failing to switch completely. Have an engineer check the manifold for scale buildup or internal blockage.
Radiators heat up when hot water tap is opened
This is a classic sign of a stuck or failed diverter valve. The internal diaphragm or plunger may require replacement using this kit.
Leakage detected underneath the boiler near the valve
Inspect the manifold seals. If the manifold body itself is cracked or the seal seats are pitted, the complete 171025 kit is the recommended replacement.

Setup, Compatibility & Care
This kit is compatible with Ideal Evo C22/24, C22/30, and C22/35 models. It is also suitable for Ideal Isar HE24, HE30, and HE35 (specifically for units with serial numbers prior to XF) and the Ideal Isar M30100. Installation involves shutting off the gas, water, and electrical supply to the boiler. The heating system must be fully drained before the manifold can be accessed or removed. Because this involves water-bearing components and is part of a gas appliance, it is strictly recommended that a qualified professional perform the installation to prevent leaks or system faults. Regular annual service by a professional will help identify if the manifold is beginning to show signs of scaling or wear.
