A real time-saver for ease of installation and seamless swapping out with i Junior, Si combi and i System boilers (2005-2015).
- Fixing points, pipe centres and distance from flue to valves match predecessor models for minimum time, effort and re-work.
- Wall-frame provides a pre-piping option for all seven combi pipe connections before the boiler is hung.
- SimpleSwitch explained When quoting for a replacement boiler, it will be fairly common that you will come across one of the Greenstar 4000s predecessors.
- SimpleSwitch refers to sharing the same positions for the top and bottom wall-frame screws, the pipework positioning, PRV, siphon and flue. The 4000 can easily switch with the following boilers: • Greenstar i Junior combi (2005-2013) • Greenstar i Junior combi (2013-2015) • Greenstar Si combi (2005-2013) • Greenstar i ErP (2015-2021) • Greenstar i System (2005-2015) • Greenstar i System ErP (2015-2021) The distance from flue to valves is identical, as are overall service clearances, to the previous model. The isolation valves are more hidden inside the boiler casing with the 4000 – for improved aesthetics.
