Worcester Greenstar 4000 60/100 SimpleSwitch Flue Adaptor

Worcester Greenstar 4000 60/100 SimpleSwitch Flue Adaptor

The Worcester Greenstar 4000 60/100 SimpleSwitch Flue Adaptor is an important fitting for creating a safe and compliant boiler installation, helping remove combustion gases from the appliance to outside air. It is a useful choice when replacing or specifying essential boiler parts for a compatible heating setup. As part of our wider boiler accessories range, this product helps installers complete the system neatly and reliably.

The Worcester Greenstar 4000 60/100 SimpleSwitch Flue Adaptor is designed to make boiler replacements quicker, cleaner, and far less disruptive. When upgrading from an older Greenstar i Junior or Si combi boiler, this adaptor allows installers to reuse the existing flue hole - meaning no core drilling, less mess, and a faster installation. The SimpleSwitch design provides a precise offset that compensates for the slight changes in flue positioning between models. This creates a smooth connection while maintaining the integrity of the building fabric. It's an efficient solution that helps reduce labour time and makes boiler swaps more straightforward for both homeowners and installers.
