Worcester Greenstar 4000 / Compact Remote PRV Kit

Worcester Greenstar 4000 / Compact Remote PRV Kit

The Worcester Greenstar 4000 / Compact Remote PRV Kit is designed to offer greater flexibility when installing a boiler, particularly in tight or central spaces. By allowing the Pressure Relief Valve (PRV) to be positioned outside of the boiler casing, installers have much more freedom when choosing the best location for pipework and discharge routes. This makes the kit especially useful for installations in places like airing cupboards, where space can be limited and accessibility is important. By relocating the PRV, servicing and maintenance also become easier, helping to ensure long-term reliability and compliance with safety requirements. Engineered specifically for the Worcester Greenstar 4000 and Greenstar Compact boiler ranges, the kit integrates seamlessly with the appliance and maintains the same high performance you’d expect from Worcester Bosch components.

FAQs

Is this remote PRV kit compatible with all Worcester Bosch boilers?

No — it is designed exclusively for the Worcester Greenstar 4000 and Greenstar Compact boiler models.

Why would I need to fit the PRV outside the boiler?

Relocating the PRV gives greater flexibility in tight spaces, improves accessibility for servicing, and allows easier routing of the discharge pipework — ideal for central locations like airing cupboards.

Does this kit need to be installed by a professional?

Yes — the PRV is a safety-critical component and must be fitted by a Gas Safe registered engineer to ensure safe and compliant installation.
